Embodiments of the invention include a lure including two or more insect attractants. The lure is optionally placed in an insect trap. Features of the lure enable the use of insect attractants that would adversely react chemically with each other. For example, an acidic attractant compound could react with an alcohol based attractant compound to form an ester. These reaction products can be less effective as attractants than their precursors. Thus, if such reactions are allowed to occur, the efficacy of the lure is reduced. This can result in a dramatically reduced shelf life for the lure. Reduced shelf life is avoided by placing attractants in different compartments and severely limiting diffusion of attractants between the compartments. Lures of the invention can include two, three, four or more compartments. The compartments may or may not be directly attached to each other.
Compartments 110 may have curved and/or flat sides. For example, in various embodiments Compartments 110 are cylindrical, hemispherical, or rectangular. Shell 115 can be formed from a wide variety of materials, such as plastic or coated paper. A single connected Shell 115 may form all three Compartments 110 making the Compartments 110 directly connected to each other. Alternatively, two or more of the Compartments 110 may be formed from different Shells 115. If formed from different Shells 115, Compartment 110A can be disposed in a different part of an insect trap. In some embodiments, Shell 115 is also part of the structure of an insect trap, e.g., a trap lid, wall or bottom of the insect trap.
Diffusion Membrane 125 is configured to control the rates diffusion of Attractants 120 from within Compartments 110. In various embodiments, Diffusion Membranes 125 are less than 50, 10, 5 and 2 thousandths of an inch thick. In contrast, the openings of Compartments 110 covered by Diffusion Membranes 125 may be on the order of ¼ to ½ to ¾ inches (or more) in length or diameter. Part of Diffusion Membranes 125 may be masked by a less (non) permeable material so as to reduce the active diffusion area from one or more of Compartments 110. In various embodiments, the active diffusion area and/or openings of Compartments 110 are less than 0.1, 0.2, 0.3, 0.5, 0.6 or 0.7 inches in length or diameter, or any range between these values. In
Other materials that may be used as membranes include, but are not limited to:
1) Polyolefins, including low-, linear low-, and high-density polyethylene (LDPE, LLDPE, HDPE), polypropylene (PP), and biaxially oriented polypropylene (BOPP)
2) Copolymers of ethylene, like ethylene-vinyl acetate (EVA), ethylene-vinyl alcohol (EVOH), and ethylene-acrylic acid (EAA)
3) Substituted olefins, like polystyrene (PS), high-impact polystyrene (HIPS, with 1,3-butadiene isomer added during the polymerization of the PS), oriented polystyrene (OPS), poly(vinyl alcohol) (PVOH), poly(vinyl chloride) (PVC), and poly(vinylidene chloride) (PVdC), and poly(tetrafluoroethylene) (PTFE)
4) Polyesters, like polyethylene terephthalate (PET), polyethylene naphthalate (PEN), and relative copolymer PET-PEN;(v)polycarbonates (PC)
5) Polyamide (PA)
6) Acrylonitriles, like polyacrylonitrile (PAN) and acrylonitrile/styrene (ANS)
7) Regenerated cellulose
8) Polylactic acid (PLA) as biodegradable polymer for food packaging contact
9) Blending, layering or lamination of with any plastic film listed above
Different Diffusion Membranes 125 can be used to cover different members of Compartments 110. The Diffusion Membranes 125 may differ in material or thickness. The selection of Diffusion Membranes 125 can be made so as to control diffusion rates of different members of Attractants 120. In some embodiments, Diffusion Membranes 125B and 125C are the same, while Diffusion Membranes 125A is different. In some embodiments, each of Diffusion Membranes 125A, 125B and 125C are different. Diffusion Membranes 125A, 125B and/or 125C may be a single piece that spans the respective members of Compartments 110. Typically thicknesses for Diffusion Membrane 125 are at less than 0.1 mils, 5 mils, 10, mils, 25 mils, 50 mils, 100 mils, or any range between these values. Any combination of the membrane materials disclosed herein may be used for Diffusion Membranes 125A, 125B and/or 125C. One of Compartments 110 may have a different membrane than the other one or two Compartments 110, or all three of Compartments 110 may have different membranes.
The diffusion occurs through a region of each of Diffusion Membranes 125A, 125B and 125C referred to as the “active diffusion area.” The size of this active diffusion area can be controlled by masking and/or by the diameter/dimensions of Compartments 110. In some embodiments the different Diffusion Membranes 125A-125C have different active diffusion areas. For example, Diffusion Membrane 125A over Compartment 110A may have a 50% greater active diffusion area relative to Diffusion Membrane 125B over Compartment 110B. In various embodiments, the active diffusion area of one of Diffusion Membranes 125A-125C is at least 25%, 50%, 100%, 200% or 300% greater than the active diffusion area of another of Diffusion Membranes 125A-125C. Differences in active diffusion areas are optionally used to control relative release rates of different lures.
Removable Sealing Layer 130 is configured to prevent significant amounts of Attractants 120 from escaping from Lure 100, prior to removal of this layer. For example, Sealing Layer 130 may comprise a foil film that provides an airtight or essentially airtight seal to Compartments 110. Sealing Layer 130 is attached in a removable fashion such that it can be peeled away leaving Diffusion Membranes 125 in place. Removable attachment of Sealing Layer 130 may be performed thermally or using an adhesive. Removal of Sealing Layer 130 allows Attractants 120 to diffuse from Lure 100 and attract insects. When attached, Sealing Layer 130 also limits (e.g., effectively prevents) diffusion of Attractants 120 between Compartments 110. For example, Sealing Layer 130 helps prevent Attractant 120B from reaching and reacting significantly with Attractants 120A or 120C. As used herein, a “significant” chemical reaction is one that results in commercially relevant degradation of the lure. In one example, a significant chemical reaction is one that would reduce the efficacy of the attractants by more than 10% at room temperature in 6 months.
Seals 135 are also configured for preventing mixing of Attractants 120. Seals 135 form a barrier between Compartments 110, and optionally between Compartments 110 and the exterior of Lure 100. Seals 135 may or may not penetrate Diffusion Membranes 125. Seals 135 may comprise an adhesive, plastic or other material. Alternatively, Seals 135 may be formed by heating and/or pressing on Sealing Layer 130 and/or Diffusion Membranes 125. For example, Seals 135 may be formed by a combination of pressure and heat that causes melting of Sealing Layer 130 and/or Diffusion Membranes 125. Seals 135 may be formed before and/or after attachment of Sealing Layer 130. In various embodiments, Seals 135 are configured to reduce diffusion of Attractants 120 between Compartments 110 to a factor of at least 100, 1000 or 10,000 times less than the diffusion out of Compartments 110 (through Diffusion Membranes 125) when Sealing Layer 130 is removed.
Attractants 120 may include any compounds known to attract insects. Generally, the purpose of dividing Attractants 120 between more than one of Compartments 110 is to prevent different Attractants 120 from reacting with each other. For example, in some embodiments acidic Attractants 120 are placed in Compartment 110A and Attractants 120 having an alcohol moiety are placed in Compartment 110B.
In addition to acids and alcohols, Attractants 120 optionally further include esters and/or other compounds found to attract insects. As used herein, acidic is used to refer to a compound having a pH less than 7; alcohol is used to refer to an organic compound having a hydroxyl functional group (—OH) bound to a saturated carbon atom; “ester” is used to refer to chemical compounds derivable from an acid (organic or inorganic) in which at least one —OH (hydroxyl) group is replaced by an —O-alkyl (alkoxy) group. Examples of compounds that may be included in Attractants 120 are listed in Tables II, III and IV. In addition to those listed in these tables, any suitable ester, saturated alcohol and/or saturated carboxylic acid may be used as an attractant. Further, in addition to those listed in Table IV, the esters used as attractants optionally include any suitable mono- or di-unsaturated compounds of up to 12 carbon atoms. In various embodiments, these saturated alcohol and/or saturated carboxylic acid include up to 4, up to 6 or up to 10 carbon atoms. Some embodiments further include attractants including mono or di-unsaturated compounds of up to 6 carbons.
In various embodiments, Lure 100 includes at least two Compartments 110A and 110B. Acetic acid is disposed in Compartment 110A and any two, three or more of the compounds listed in Table III are disposed in Compartment 110B. In various embodiments, Lure 100 includes at least three Compartments 110A, 110B and 110C. Acetic acid is disposed in Compartment 110A; ethanol is disposed in Compartment 110B; and acetoin and methionol are disposed in Compartment 110C. In various embodiments, Lure 110 includes at least three Compartments 110A, 110B and 110C; acetic acid is disposed in Compartment 110A; a first of the compounds listed in Table III is disposed in Compartment 110B; and at least a second and third of the compounds listed in Table III disposed in Compartment 110C. In various embodiments, a Lure 100 includes at least four Compartment 110; acetic acid disposed in a first of Compartments 110; ethanol is disposed in a second of Compartments 110; acetoin is disposed in a third of Compartments 110; and methionol is disposed in a fourth of Compartments 110. Acetoin is a solid dimer at room temp, so water, ethylene glycol, propylene glycol and other diluents can be added as a solvent. In some embodiments the solvent is selected for the resulting mixture to have an equivalent or higher vapor pressure than the solvent alone. Attractants 120 can be in solid or liquid form. The order of Compartments 110A, 110B and 110C is typically not important, and as used herein the identification of them as “first-second” or “110A-110B” etc. is not meant to indicate a requirement for an actual physical order.
The lures used in Compartment 110A-110C are optionally configured to attract one or more of the insects listed in Table V.

Other compounds that may be included in Compartments 100A-110C include those listed in Table VI. These compounds, and those included in Tables II-IV, are used in any combination, in various embodiments of the invention.
In a Place First Attractant Step 820 a first insect Attractant 120A is placed in the first Compartment 120A. In various embodiments, this Attractant 120A can include any of the Attractants 120 described elsewhere herein. In a Place Second Attractant Step 825, Attractant 120B is placed in the second Compartment 120B. This Attractant 120B can include any of the Attractants 120 described herein, but is typically different than Attractant 120A. In an optional Place Third Attractant 830, Attractant 120C is placed in optional Compartment 120C. This Attractant 120C can include any of the Attractants 120 described herein, but is typically different than Attractants 120A and 120B. Similar steps may be performed for additional compartments. The results of Steps 820-830 include any of the combinations of Attractants 120 disclosed elsewhere herein. For example, Attractant 120A may comprise Acetic Acid, Attractant 120B may include Ethanol or a combination of Ethanol, Acetoin and Methionol, Attractant 120C may include a combination of Acetoin and Methionol. As discussed elsewhere herein, other useful chemicals can be added to the Compartments 110 discussed herein, or to additional compartments within Lure 100. This optionally occurs during Steps 820-830.
In an Apply Diffusion Membrane Step 835, Diffusion Membrane 125A is applied to Compartment 110A, Diffusion Membrane 125B is applied to Compartment 110B, and optionally Diffusion Membrane 125C is applied to Compartment 110C, etc. As discussed elsewhere herein, Diffusion Membranes 125 are configured to control diffusion of Attractants 120 from the respective Compartments 110.
In some embodiments the application of Diffusion Membranes 125A, 125B and 125C is performed in a single step using a single sheet of membrane. For example, a sheet of polymer membrane may be placed over Shell 115 and attached using adhesive and/or heat at the locations illustrated in
In an Apply Seal Layer 840, removable Sealing Layer 130 is applied to Lure 100. As discussed elsewhere herein, Sealing Layer 130 is configured to seal Lure 100 and Compartments 110 so as to prevent appreciable amounts of Attractants 120 from being released from Lure 100, prior to removal of Sealing Layer 130. Sealing Layer 130 further prevents Attractant 120A from diffusing from Compartment 110A through Diffusion Membranes 125A and 125B to Compartment 110B. Sealing Layer 130 can be attached using pressure, heat, solvent, adhesive, and/or any other removable attachment mechanism known in the art. In some embodiments the Sealing Layer 130 is attached at positions illustrated in
In some embodiments, the attachment of Diffusion Membranes 125 and/or Sealing Layer 130 results in the formation of Seals 135. For example, the attachment of these elements can result in a diffusion path from Compartment 110A to Compartment 110B through Diffusion Membranes 125A and 125B that is tenths of an inch, this effectively eliminates diffusion between these two compartments, e.g., it effectively seals the Compartments 110 from each other. The effective elimination of diffusion between Compartments 110 significantly limits chemical reactions between Attractants 120 from different Compartments 110 to inconsequential trace levels that do not impact the shelf life of Lure 100. These reactions are prevent from occurring in other than trace, inconsequential amounts.
In an optional Add to Trap Step 845, Lure 100 is added to Trap 410. Lure 100 can be hung in Trap 410 as illustrated in
