Insects, especially those reared in a laboratory, may require transportation between various stations within the laboratory and to different locations outside of the laboratory. Depending on the stage of development of the insects, different means of transportation may be appropriate.
Various examples are described relating to devices, systems, and methods for insect storage and release.
One general aspect includes an insect storage and release device, including: a bottom, a top flange, and a perimeter wall that connects the bottom and the top flange, where the perimeter wall and the bottom form a cylinder that defines a cylindrical interior volume for receiving a population of insects, and where an opening is formed in the top flange. The insect storage and release device also includes a population of insects disposed within the interior volume. The insect storage and release device also includes a lid sized and configured to enclose the opening and prevent the population of insects from exiting the cylinder.
Another general aspect includes a system, including: a bottom section including a plurality of insect sections, each insect section including an insect compartment, each insect compartment including at least one live insect. The system also includes a lid that extends over and encloses each insect compartment. The lid is configured for individual access to each insect compartment.
Another general aspect includes a method of compressing insects, including: loading an insect container into a retainer. The method of also includes adding a population of insects to an interior volume of a compression device. The method also includes adding a foam section to the interior volume of the compression device. The method also includes compressing the interior volume of the compression device and transferring the population of insects and the foam section to the insect container.
Another general aspect includes an insect rearing device, including: a pouch in which is formed a pocket. The insect rearing device also includes a first duct connected to a first side of the pocket and extending in a first direction. The first duct is configured to retain an aqueous solution, larvae insect food, and one or more insect larvae. The insect rearing device also includes a second duct connected to a second side of the pocket and extending in a second direction, the second duct configured to retain adult insect food.
The accompanying drawings, which are incorporated into and constitute a part of this specification, illustrate one or more certain examples and, together with the description of the example, serve to explain the principles and implementations of the certain examples.
Examples are described herein in the context of storage of adult stage insects, and in particular adult stage mosquitoes. Those of ordinary skill in the art will realize that the following description is illustrative only and is not intended to be in any way limiting. For example, the techniques described herein can be used to store mosquitoes in other stages of development and/or other insects. Reference will now be made in detail to implementations of examples as illustrated in the accompanying drawings. The same reference indicators will be used throughout the drawings and the following description to refer to the same or like items.
In the interest of clarity, not all of the routine features of the examples described herein are shown and described. It will, of course, be appreciated that in the development of any such actual implementation, numerous implementation-specific decisions must be made in order to achieve the developer's specific goals, such as compliance with application- and business-related constraints, and that these specific goals will vary from one implementation to another and from one developer to another.
As part of a sterile insect technique (SIT) program or otherwise, it is desirable to release known quantities of sterile insects into a target environment. The systems and devices described herein are used to load, store, and transport known quantities of such sterile insects in easy-to-use single-use or reusable containers. Each container may hold as few as one insect or can be scaled to hold hundreds, thousands, tens of thousands, or even more insects. To increase density, in some applications, insects are compressed as they are loaded into containers.
Sheets or rolls of containers, which may include multiple containers, may be produced, loaded, and sent for distribution. Using sheets or rolls of containers enables “dosing” selection in which set numbers of containers can be opened and released. The containers described herein may be shipped to end users for release. For example, a homeowner participating in a SIT program may receive, in the mail or otherwise, a package of containers including a set number of insects and instructions for releasing the insects (e.g., release one container per day for a week). The homeowner may be responsible for opening the containers and releasing the insects. For example, for a typical yard, about two containers of 1000 mosquitoes may be opened each week.
Turning now to a particular example, a single-use insect storage and release device includes a cup having a cylindrical shape, and a cap. The insect storage and release device is configured to hold a compressed quantity of insects within an interior volume of the cup. To load the insect storage and release device, the cup is placed into a retainer of a loading device with an opening of the cup facing up. A barrel of a syringe is loaded with a reticulated foam wafer that has a diameter about equal to a cross-sectional area of the opening. A quantity of insects is then loaded into the barrel. With the foam wafer and insects in the barrel, a structure supporting the barrel is used to align the barrel with the cup in the retainer. Once aligned, a plunger of the syringe is used to push the insects via the foam into the interior volume of the cup, thereby compressing the insects beneath the foam. Once foam has passed into the interior volume, loading concludes. The cap may then be placed on the cup to keep the insects and the foam from escaping the interior volume. The cap and/or the cup may include small perforations or slits to provide ventilation for the insects within the interior volume.
This illustrative example is given to introduce the reader to the general subject matter discussed herein and the disclosure is not limited to this example. The following sections describe various additional non-limiting examples of insect storage and release systems.
Turning now to the Figures,
The insect storage and release device 100, which is illustrated with a top portion resting on a surface, includes a top flange 102, a bottom 104, and a side wall 106 that together define an interior volume 110, which may be referred to as an insect compartment. The side wall 106 may be around 20 mm tall and the interior volume may have a diameter of around 20 mm. In some examples, the side wall may be greater than or less than 20 mm tall and the diameter may be greater than or less than 20 mm. The dimensions of the side wall and diameter may be selected based on a quantity of insects to store in the insect storage and release device 100 and a packing density for the insects (e.g., a quantity of insects per volume). In some examples, other factors, which may relate to packing density or otherwise, such as a mortality rate (e.g., a percentage of insects that die during packing and/or transport) may also be considered.
The insect storage and release device 100 has a cylindrical form factor, but other form factors such as rectangular, bulbous, and those corresponding to other shapes are also possible. The bottom 104 includes a perforated section 108. The perforated section 108 includes small slits, cuts, holes, or other perforations to enable air flow into and out of the interior volume 110. This allows air transfer between the interior volume 110 and outside the insect storage and release device 100. A lid such as one described with reference to later figures is used to seal an opening formed where the top flange 102 and an upper edge of side wall 106 intersect.
The illustrated insect storage and release device 100 is formed from a thermoformable plastic. However, other materials may be employed such as foil, paper, compostable products, rubbers, silicone/urethane, foam, 3D printed resin and filament, insect food (e.g., sucrose, bread, etc.). In some examples, the material used may be color coded to signify a characteristic such as volume of the container or quantity of insects held therein. The material may also be tinted (e.g., tinted plastic), UV protected (e.g., UV protected plastic), and have color-changing properties.
The insect storage and release device 100 may also be loaded with food (e.g., sugar water, sugar capsule, etc.). In some examples, the sugar water mixture is placed on the opposite side of the perforated section 108 and/or included in a foam wafer placed in the insect storage and release device 100.
In some examples, the insect storage and release device 100 is loaded directly from an insect sortation system. The insect sortation system may be configured to singulate and sort insects based on predefined characteristic (e.g., sex, species, size, etc.). Once singulated, the insects can be blown, driven, or otherwise loaded into the insect storage and release devices 100 from a singulation pathway of the insect sortation system. In some examples, insects from the singulation pathway are loaded into a holding chamber, and the insects are loaded from the holding chamber into the insect storage and release device 100. Whether using a singulation system or otherwise, the insect storage and release device 100 may be used to store insects of a particular characteristic (e.g., all male insects, all female insects, etc.).
The illustrated foam section 212 is a reticulated foam. However, any other open cell foam, silicone, plastic, or other material capable of being compressed similarly to such open-cell foams, etc. may be employed in place of the reticulated foam. The foam section 212 may be soaked in food, such as sugar water, for insects within the interior volume 210. In some examples, the interior volume 210 of the insect storage and release device 200 (and any other insect storage and release device described herein) is loaded with insect food such as a piece of fruit, sugar water, and any other such food. In other examples, food is supplied to insects within the insect storage and release device 200 (or within any other insect storage and release device) through openings in the bottom 204, the side wall 206, and/or the lid when these openings contact the food. For example, the insect storage and release device 200 (or any of the other insect storage and release devices described herein) may be placed on a towel, sponge, foam, or other absorbent object that has absorbed a liquid food (e.g., sugar water).
In some examples, a pressure-maintaining item is installed in between the foam section 212 and the lid. The pressure-maintaining item, which may include a variable force spring, a rigid pieces of material, such as a rigid plastic or metallic disk, a constant force spring, or other such item, may function to apply and/or maintain a constant pressure within the interior volume 210. For example, after the foam section 212 has been added to the interior volume 210, the pressure-maintaining item can be added, followed by the lid. The pressure-maintaining item may exert a force on the foam section 212 to ensure a constant pressure is maintained inside the interior volume 210.
The insect storage and release device 300 includes a lid 314 attached to a top flange 302 that encloses an interior volume 310. The insect storage and release device 300 also includes a foam section 312 located within the interior volume 310 between the lid 314 and a population of insects 316. The lid 314 includes an adhesive backing that is used to seal the lid to a top surface of the top flange 302. For example, the lid 314 may be formed from drywall tape (e.g., Tyvek® brand tape), peelable foil, perforated plastic, any other similar materials. In some examples, the lid 314 is formed from the foam section 312 or a second foam section. This example insect storage and release device 300 relies on air flow via the lid 314, i.e., the bottom 304 and the wall 306 are not perforated. As such, the lid 314 includes perforations and/or is formed from a material that allows breathability (e.g., air flow in and out of the interior volume 310). However, in some examples one or more of the lid, 314, the bottom 304, or the wall 306 may be perforated.

The insect compression device 530 includes a retainer block 532 and a compression apparatus 534. Generally, the retainer block 532 is configured to receive and retain an insect storage and release device 500 while the insect storage and release device 500 is being loaded with insects. The compression apparatus 534 is used to compress the insects into the insect storage and release device as it is retained by the retainer block 532.
Beginning with the retainer block 532, the retainer block 532 includes a set of alignment holes 536a-d surrounding a concave depression 538. The alignment holes 536 correspond to a set of alignment posts 540a-d of the compression apparatus 534, and are used to align the compression apparatus 534 with the retainer block 532. In the view depicted in
The concave depression 538 is configured to receive and retain the insect storage and release device 500. As such, the size and shape of the concave depression 538 may correspond to an exterior form factor of the insect storage and release device 500. In this example, the concave depression 538 may more or less has a cylindrical shape that corresponds to the cylindrical shape of the insect storage and release device 500 (e.g., such as the insect storage and release devices 100-400 described with respect to
Turning now to the compression apparatus 534, the compression apparatus 534 includes a chamber 542 including a distal opening 544a and a proximate opening 544b, a plunger 546 including a distal end 548 and a handle 550, along with the alignment posts 540 introduced previously. The chamber 542 defines an interior volume extending between the two openings, 544a and 544b. The plunger 546 is configured to travel longitudinally (e.g., translate) within the interior volume of the chamber 542. To move the plunger 546, a user or a robotic device may exert a force on the handle 550 (e.g., either pushes to move the distal end 548 toward the distal opening 544a or pulls to move the distal end 548 toward the proximate opening 544b).
To operate the insect compression device 530, the compression apparatus 534 is separated from the retainer block 532. An insect storage and release device 500 is loaded into the concave depression 538 of the retainer block 532. The plunger 546 is pulled back within the chamber 542 to define a loading volume extending within the chamber 542 between the distal opening 544a and the distal end 548 (e.g., the distal end 548 is moved adjacent to the proximate opening 544b). Once the plunger 546 is in this position, a foam section 512 (e.g., the foam section 512 and/or a lid) is loaded into the chamber 542 via the distal opening 544a until it wrests against the distal end 548. A population of insects 516 may then be loaded into the chamber 542 via the distal opening 544a. In other examples, the distal end 548 is removed entirely from the chamber 542 and the population of insects 516 and the foam section 512 are loaded via the proximate opening 544b. Following these actions, the compression apparatus 534 and the retainer block 532 are brought into alignment via the alignment posts 540 and the alignment holes 536. Finally, the plunger 546 is moved through the interior volume of the chamber 542 such that the distal end 548 pushes the foam section 512 and the insects 516 toward the retainer block 532, which includes the insect storage and release device 500 loaded into the concave depression 538. In some examples, a packing pressure of substantially 0.5 PSI and 3 PSI may be applied to the insects 516 during packing. This pressure may depend on the force applied at the handle 550 given an area of the plunger 546. Once the insects 516 and the foam section 512 are within the insect storage and release device 500, the insect compression device 530 may be separated from the retainer block 532 and the loaded insect storage and release device 500 may be removed from the concave depression 538. In some examples, a lid may be loaded into the chamber 542 and translated within the interior volume as part of compressing the insects 516.
During loading of the insect storage and release device 500 using the insect compression device 530, the foam section 512 may be added to provide compliance during compression as well as to reduce damage to the insects 516 (e.g., the foam section 512 provides pressure on the insects 516, but does so without crushing the insects 516). The foam section 512 also allows the insects 516 to breathe.
In some examples, the insect compression device 530 includes any suitable compression cylinder/piston arrangement, cam shaft compression arrangement, or other suitable compression arrangement. This may enable automated loading. As described elsewhere herein, multiple insect compression devices 530 may be held together in an array of insect compression devices 530 to enable loading of multiple insect storage and release devices 500 simultaneously.
In some examples, the insect storage and release device 600 (or any other insect storage and release device) may take the form factor of single-dispense blister packs such as those used to package medicine. For example,
In some examples, the number of insects within each of the insect storage and release devices 600 on the sheet 756 may vary (e.g., 1 insect in one and 20 insects in another) or may be consistent (e.g., a full sheet of insect storage and release devices 600 each including 1 insect). In some examples, the sheet 756 is manufactured and loaded based on an order for a particular number of insects to be released at some dosage interval (e.g., 1 insect on a first day, 5 insects on a second day, 10 insects on a third day, etc.). The number of insect storage and release devices 600 in the sheet 756 may be defined as an array having any suitable number of rows and columns (e.g., 10×10, 1×1, 10×1, etc.).
The insect rearing and storage device 857 includes a pouch 862 in which is formed a pocket 860. The pocket 860 forms a main chamber of the insect rearing and storage device 857. The insect rearing and storage device 857 also includes a first duct 864 connected to a first side of the pocket 860 and extending in a first direction and a second duct 866 connected to a second side of the pocket 860 and extending in a second direction. The first duct 864 is configured to retain an aqueous solution, larvae insect food 868, and one or more insect larvae. The second duct 866 is configured to retain adult insect food 870. The first duct 864 includes a proximate end that terminates at the pocket 860 and a distal end that terminates radially from the pocket 860. The second duct 866 includes a proximate end that terminates at the pocket 860 and a distal end that terminates laterally from the pocket 860.
In operation, one or more larvae and water are added to the first duct 864 while the insect rearing and storage device 857 is in the illustrated orientation. The larvae feed on the larvae insect food 868 and develop into pupae. Once this has occurred, the device 857 is rotated 90 degrees to the left. This causes the pupae to move through the first duct 864 and into the pocket 860, e.g., by gravity. Within the pocket 860, the pupae are suspended in water that drained from first duct 864 or other water while the develop into adults. Once adults, the insects can access the adult insect food 870 in the second duct 866. To provide air exchange for the insects, the insect rearing and storage device 857 includes a perforated section disposed at a suitable location of the pocket 860.
The system 974b includes the balloon 976 with the opening 978 stretched over a container 980. The insects are loaded into the balloon 976 with the opening 978 stretched in this manner. Once within the balloon 976, the air can be evacuated from the balloon 976 to compress the insects.
The system 974c includes the balloon 976 and a loading straw 982. The loading straw 982 is inserted into an opening of the balloon 976. The insects are loaded into the balloon 976 via the loading straw 982. Once the insects have been loaded, the loading straw 982 may be removed from the balloon 976.
In some examples, loading insects, whether using the insect loading and storage system 1084, the insect compression device 530, or any other loading device suitable for loading insects, may be include cooling, gassing using CO2 or other suitable gas, or other suitable techniques to immobilize the insects. For example, the temperature may be held between 9 degrees C. and 14 degrees C. In some examples, the insects are stored at this temperature, whether under compression or otherwise.
In some examples, the top strip 1196 includes an adhesive backing that connects the top strip 1196 to the bottom strip 1198. As the insect release system 1194 is indexed on an insect release device, the top strip 1196 may be separated from the bottom strip 1198 to release the insects held within the insect storage and release devices 100. Once opened, the insect release device may include a blower to blow the insects from the insect storage and release devices 100.
Turning now to the details of the insect storage and release system 1400, the insect storage and release system 1400 includes a bottom container 1410 and a lid 1412. The bottom container 1410 includes a floor 1414 and a wall 1416 that encircles the wall 1416 to define an interior volume. The lid 1412 is sized to seal with a perimeter edge of the wall 1416 to enclose the interior volume of the bottom container 1410. When assembled, the lid 1412 may be brought towards the floor 1414 at least until a perimeter edge of the lid 1412 engages with the perimeter edge of the wall 1416 and/or interior surfaces of the wall 1416. The insect storage and release system 1400 may hold insects in a compressed state by pressing the lid 1412 against the bottom container 1410 to a predetermined pressure level while the insects are held in place between the lid and the bottom container. For example, the insects may be loaded in accordance with a packing pressure, as described herein. For example, the packing pressure may be measured given a force applied to the lid 1412 as it is brought into contact with the bottom container 1410 and a surface area of the bottom container 1412. In some examples, the packing pressure may be substantially between 0.5 PSI to 3 PSI. In some examples, the pressure may be lower than 0.5 PSI and may be higher than 3 PSI. In some examples, one or more pressure-maintaining items such as pneumatic cylinders or other resilient devices (e.g., spring) may be interposed between one or more layers of bottom containers 1410 and/or lids 1412 to maintain a constant compressive force between layers. The packing pressure may be used for packing insects in other insect storage and release systems described herein.
In some examples, combinations of bottom containers 1410 and lids 1412 may be stacked on top of each other to create a stacked arrangement of insect storage and release systems 1400. In some examples, the stacked arrangement of insect storage and release systems 1400 may be placed within a cylindrical tube or tube having a different cross section for bottom containers 1410 and lids 1412 having different cross sections (e.g., rectangular, etc.). The tube may function to retain the stacked insect storage and release systems 1400 and provide rigidity when the insect storage and release systems 1400 are transported. To release insects from one of the insect storage and release systems 1400, all insect storage and release systems 1400 within the tube (e.g., all “layers” of storage and release systems 1400) may be translated within the tube until a top insect storage and release system 1400 is adjacent a top opening of the tube. At this point, the lid 1412 of the top insect storage and release system 1400 may be removed and the insects within the corresponding bottom container 1410 may be free to exit the bottom container 1410 and/or the tube. Releasing insects from one bottom container 1410 may constitute a metered “dose” of insects, where a dose includes a quantity of insects from a discrete layer of the insect storage and release system (or from the entire system if only a single layer is employed). In some examples, the number of insects loaded into the bottom container 1410 may be metered such that each bottom container 1410 holds roughly the same quantity of insects. It should be appreciated that different sized doses of insects may be stored in different layers. For example, a first layer may include 100 insects, a second layer may include 50 insects, and a third layer may include 200 insects.
To store adult insects in the insect storage and release system 1400, the insects, such as mosquitoes, are first loaded into the bottom container 1410. This may include suppressing (e.g., sedating or otherwise reducing the energy level) the insects before placing them in the bottom container 1410. After the insects have been loaded into the bottom container 1410, the lid 1412 is releasably coupled with the wall 1416. In this manner, the insects may be retained within the volume bounded by the floor 1415, the wall 1416, and the lid 1412. In some examples, the lid 1412 may be releasably coupled with the wall 1416 using any suitable coupling such as a hook and loop fastener (e.g., Velcro® brand hook and loop fastener), adhesive, or other coupling disposed at the perimeter edges. To release insects from one layer (e.g., one bottom container 1410 and one lid 1412), the lid 1412 for that layer may be removed from the respective bottom container 1410 to reveal the interior volume. At this point, the insects may be free to fly from the bottom container 1410. In some examples, a blower, heater, and/or any other revival device may be arranged to encourage evacuation of the insects from the bottom container 1410.
In some examples, at least some bottom containers 1410 in a stack of insect storage and release systems 1400 may hold different quantities of insects. For example, a dosing requirement for a particular application may require a first insect quantity to be released on a first day, a second insect quantity to be released on a second day, and a third insect quantity to be released on a third day. Given this requirement, a stack of insect storage and release systems 1400 may be formed in which a top insect storage and release system 1400 may include the first insect quantity, a middle insect storage and release system 1400 may include the second insect quantity, and a bottom insect storage and release system 1400 may include the third insect quantity. The stack of insect storage and release systems 1400, whether in a tube or not, may be shipped with instructions for release. The instructions may inform a user that on a first day remove the lid 1412 of the top insect storage and release system 1400, on the second day remove the bottom container 1410 of the top insect storage and release system 1400 and the lid 1412 of the middle insect storage and release system 1400 and, and on the third day remove the bottom container 1410 of the middle insect storage and release system 1400 and the lid 1412 of the bottom insect storage and release system 1400.
As illustrated, the insect storage and release systems 1400a and 1400b are structurally similar, with the exception that the insect storage and release system 1400b also includes a floor opening 1408 in the floor 1414b of the bottom container 1410b and a lid opening 1418 in the lid 1412b. As illustrated in
The mounting structure 1520 is illustrated as including sections of foam 1528 (e.g., reticulated foam) arranged into layers. In this example, the mounting structure 1520 may be placed within a cylindrical container with the insects being placed between layers of the insect storage and release systems 1400 and the reticulated foam sections 1528. In some examples, the reticulated foam sections 1528 may be any other open cell foam, silicone, plastic, or other material capable of being compressed may be employed in place of the reticulated foam. The reticulated foam sections 1528 may occupy any excess volume within the interior volume and enable compression of the insects within the interior volume. The reticulated foam sections 1528 may be soaked in sugar water to provide food for insects within the interior volume.
The insect storage and release system 1400 has a cylindrical form factor (i.e., the bottom container 1410 and the lid 1412 have circular cross or ovoid sections), but other form factors such as rectangular, triangular, spherical, bulbous, and other shapes are also possible.
The retaining structures 1604 may include one or more sheets of planar material such as paper, plastic, metal, etc. In some examples, at least two retaining structures 1604a may form an insect storage and release subsystem by which insects may be stored. For example, the retaining structure 1604a may function as a containing layer of the subsystem to define an interior volume and may be used to retain a quantity of insects, and the retaining structure 1604b may function as a lid layer of the subsystem to define a lid for the containing layer. In this example, the retaining structure 1604a may also function as a lid layer of a subsystem that includes the retaining structure 1604N functioning as the containing layer.
In some examples, the retaining structures 1604 may function to retain other elements that are used to store insects. For example, structures similar to insect storage and release systems 1400 may be loaded in between the retaining structures 1604, and held in compression by the retaining structures 1604.
Depending on the application, the insects may be released from the insect storage and release system 1600 by separating the top and bottom retaining structures 1604 that are holding the insects. For example, in the illustrated system 1600, the insects held between the retaining structure 1604a and the retaining structure 1604N may be free for release.
Generally, insects may be held between coaxial layers. For example, the pliable mat 1812 may be rolled out as in the partially rolled state 1808, and insects (e.g., in a sedated state) may be placed on the first side 1810a. Next, the pliable mat 1812 may be rolled about the roll axis 1816 such that the insects are held between the first side 1810a and the second side. In some examples, the pliable mat 1812 also includes an insect retaining material and/or coating disposed on at least the first side 1810a. For example, an open-cell foam may be provided on the first side 1810 to give the insects some place to roost or otherwise go when the pliable mat 1812 is rolled. To release insects, at least some portion of the pliable mat 1812 may be unrolled. In this manner at least some of the insects held between the layers may be exposed to the open air. At this point, the insects may be free to fly from the pliable mat 1812. In some examples, a blower, heater, and/or any other revival device may be arranged to encourage evacuation of the insects from the pliable mat 1812.
In some examples, the pliable mat 1812 also includes one or more retaining devices 1814. The retaining devices 1814, which may be located on one or both sides 1810 and/or as a separate device, are provided to retain the pliable mat 1812 in the rolled state 1808. For example, the retaining devices 1814 may include hook and loop fasteners (e.g., hooks on the first side 1810a and loops on the second side) that couple as the pliable mat 1812 is rolled about the roll axis 1816. The retaining devices 1814 may also be used to maintain a suitable compression force between layers of the roll. A tension for rolling the pliable mat 1812 may be computed based on a desired compression force between layers. The retaining devices 1814 may be configured to maintain this compression force by holding the layers.
Insects may be loaded and held in between opposing top and bottom surfaces of the storage layers 1906. For example, the insects may be loaded and held between the second surface 1912b of the planar section 1908a and the third surface of the 1912c of the planar section 1908b. Other insects may be held between the fourth surface 1912d and the fifth surface 1912e. In this manner, the insects are held and retained in between opposing surfaces of the Z shape. Thus, in at least one example, the insect storage and release system 1900 includes a single layer 1906 that includes a structure that is comparable in shape and design to the layers of the insect storage and release device 1706. In the system 1900, however, each layer may be connected via additional joint sections 1910 to make one uniform Z folding structure. To release insects, the planar sections 1908 may be separated from each other. At this point, the insects may be free to fly out of the V-shaped structure. In some examples, a blower, heater, and/or any other revival device may be arranged to encourage evacuation of the insects from the surfaces of the layers 1906.
The system 1900 may also include retaining devices configured to maintain compression within the stack of layers. For example, rubber bands, straps, tension clips, or the like may be used to hold the layers in compression.
The insect storage and release system 2000 includes at least two insect retaining sections 2006a-2006N connected to a pliable mat 2008 (e.g., at the top side 2010a). In this example, the pliable mat 2008 is formed from a rectangular piece of thin paper and is divided into a plurality of mat sections 2012a-2012N. The insect retaining sections 2006 may be formed from a foam. The insect retaining sections 2006 may be spaced roughly equally apart from each other on the pliable mat 2008, with the space between being about equal to a width of a single insect retaining section 2006 (e.g., a mat section 2012). In the expanded state illustrated in the first perspective view 2002 with the top side 2010a facing up, the insects may be placed on the insect retaining section 2006a. After which, the mat section 2012b may be folded onto the insect retaining section 2006a to provide a barrier between the insect retaining section 2006a and the insect retaining section 2006b. The similar approach can be taken for loading insects in the insect retaining section 2006b. Once all layers have been loaded, the insect storage and release system 2000 will take the form of the stacked state in perspective view 2004. To release the insects held within an insect retaining section 2006, the mat section 2012 that is on top of the insect retaining section 2006 may be removed to reveal the insects to the open air. At this point, the insects may be free to fly off of the insect retaining section 2006. In some examples, a blower, heater, and/or any other revival device may be arranged to encourage evacuation of the insects from the surfaces of the insect retaining sections 2006.
The system 2000 may also include retaining devices configured to maintain compression within the stack of layers. For example, rubber bands, straps, tension clips, or the like may be used to hold the layers in compression.
The illustrated insect storage and release systems described herein may be formed from a thermoformable plastic, foil, paper, compostable products, rubbers, silicone/urethane, foam, 3D printed resin and filament, insect food (e.g., sucrose, bread, etc.). In some examples, the material used may be color coded to signify a characteristic such as volume of the container or quantity of insects held therein. The material may also be tinted (e.g., tinted plastic), UV protected (e.g., UV protected plastic), and have color-changing properties. The insect storage and release system described herein may also be loaded with food (e.g., sugar water, sugar capsule, etc.).
In some examples, the insect storage and release systems described herein are loaded directly from an insect sortation system. The insect sortation system may be configured to singulate and sort insects based on predefined characteristic (e.g., sex, species, size, etc.). Once singulated, the insects can be blown, driven, or otherwise loaded into the insect storage and release systems from a singulation pathway of the insect sortation system. In some examples, insects from the singulation pathway are loaded into a holding chamber, and the insects are loaded from the holding chamber into the insect storage and release systems.
In some examples, the insect storage and release devices may include climate or other environmental control such as temperature, humidity, and/or pressure control. Such control may be maintained during storage, packing, shipping, transportation, etc. In some examples, the insect storage and release devices may be compatible for feeding of insects. In some examples, the insect storage and release devices may include a tracking mechanism such as radio-frequency identification (RFID) tracking. In some examples, the insect storage and release devices may enable timed release such as a maze form factor (e.g., designed such that it takes an insect some predefined amount of time to exit), barrier (e.g., food barrier that is eaten by insects), or dissolvable. For example,
Releasing the insects from the insect storage and release devices described herein may be performed in any suitable manner, which may include, for example, placing the insects onto a recovery plate (e.g., a foam mat) and allowing the insects to recover on the plate, placing the insects onto a tray below an airstream. As the insects fly up into the airstream the insects will get blown out of the release device.
The insect packing curve 2102 represents a packing curve for compressed insects. In particular, the graph 2100 illustrates the number of mosquitoes packed per cubic center along the X axis 2104 (increasing in number of insects from a lowest quantity on the far left to a highest quantity on the far right) and the percentage of male mosquitoes undamaged along the Y axis 2106. In this example, when the density is around 200 male mosquitoes per cubic centimeter, the lowest percentage of those insects is damaged.
At block 2204, the process 2200 includes adding a population of insects to an interior volume of a compression device (e.g., the compression apparatus 534). For example, this may include loading insects into the chamber 542. In some examples, the compression device includes a syringe held within a mounting bracket that aligns with and is releasably coupled to the retainer. In this example, the interior volume may be defined within a barrel of the syringe.
At block 2206, the process 2200 includes adding a foam section to the interior volume of the compression device. For example, this may include adding the foam section 212 into the chamber 542. Depending on which end of the compression device is loaded with insects, the block 2204 may be performed before or after the block 2206.
At block 2208, the process 2200 includes compressing the interior volume of the compression device and transferring the population of insects and the foam section to the insect container. This may include applying a force to the plunger 546 of the compression apparatus 534 to cause the plunger to translate within the interior volume and transfer the insects into the insect container.
In some examples, the block 2208 includes compressing the interior volume at least until a predefined packing pressure of the interior volume is reached. In this example, the process 2200 may further include adding a pressure-maintaining item to the interior volume such that a first portion of the pressure-maintaining item contacts the foam section, and adding a lid to the insect container to enclose the interior volume such that a second portion of the pressure-maintaining item contacts an interior portion of the lid. The pressure-maintaining item may be configured to maintain the predefined packing pressure of the interior volume by asserting opposing forces on the foam section and the lid. The pressure-maintaining item may include at least one a spring or a constant force material.
In some examples, the process 2200 may further include suppressing the population of insects at a particular temperature. For example, the population of insects may be chilled at a particular temperature (e.g., between 9 degrees C. and 14 degrees C.) to reduce their activity. In some examples, at least one of blocks 2204-2208 is performed at the particular temperature.
In some examples, the process 2200 may further include maintaining at least one environmental condition of the interior volume at least while performing the block 2208. The environmental condition may include at least one of humidity or pressure.
