The invention relates to mitigation of arthropods in general and particularly to systems and methods for mitigating arthropods without application of chemical agents.
The Centers for Disease Control (CDC) has recently reported that illnesses from mosquito, tick, and flea bites have tripled in the U.S., with more than 640,000 cases reported during the 13 years from 2004 through 2016. Nine new germs spread by mosquitoes and ticks were discovered or introduced into the United States during this time. See “Illnesses on the Rise” Vital Signs, CDC News Release dated May 1, 2018, copy appended hereto.
This is CDC's first summary collectively examining data trends for all nationally notifiable diseases caused by the bite of an infected mosquito, tick, or flea. It provides detailed information on the growing burden of mosquito-borne and tickborne illnesses in the U.S.
Zika, West Nile, Lyme, and chikungunya—a growing list of diseases caused by the bite of an infected mosquito, tick, or flea—have confronted the U.S. in recent years, making a lot of people sick.
In the United States, some ticks carry pathogens that can cause human disease, including:
Anaplasmosis is transmitted to humans by tick bites primarily from the blacklegged tick (Ixodes scapularis) in the northeastern and upper midwestern U.S. and the western blacklegged tick (Ixodes pacificus) along the Pacific coast.
Babesiosis is caused by microscopic parasites that infect red blood cells. Most human cases of babesiosis in the U.S. are caused by Babesia microti. Babesia microti is transmitted by the blacklegged tick (Ixodes scapularis) and is found primarily in the northeast and upper midwest.
Borrelia mayonii infection has recently been described as a cause of illness in the upper midwestern United States. It has been found in blacklegged ticks (Ixodes scapularis) in Minnesota and Wisconsin. Borrelia mayonii is a new species and is the only species besides B. burgdorferi known to cause Lyme disease in North America.
Borrelia miyamotoi infection has recently been described as a cause of illness in the U.S. It is transmitted by the blacklegged tick (Ixodes scapularis) and has a range similar to that of Lyme disease.
Bourbon virus infection has been identified in a limited number patients in the Midwest and southern United States. At this time, we do not know if the virus might be found in other areas of the United States.
Colorado tick fever is caused by a virus transmitted by the Rocky Mountain wood tick (Dermacentor andersoni). It occurs in the Rocky Mountain states at elevations of 4,000 to 10,500 feet.
Ehrlichiosis is transmitted to humans by the lone star tick (Ambylomma americanum), found primarily in the southcentral and eastern U.S.
Heartland virus cases have been identified in the Midwestern and southern United States. Studies suggest that Lone Star ticks can transmit the virus. It is unknown if the virus may be found in other areas of the U.S.
Lyme disease is transmitted by the blacklegged tick (Ixodes scapularis) in the northeastern U.S. and upper midwestern U.S. and the western blacklegged tick (Ixodes pacificus) along the Pacific coast.
Powassan disease is transmitted by the blacklegged tick (Ixodes scapularis) and the groundhog tick (Ixodes cookei). Cases have been reported primarily from northeastern states and the Great Lakes region.
Rickettsia parkeri rickettsiosis is transmitted to humans by the Gulf Coast tick (Amblyomma maculatum).
Rocky Mountain spotted fever (RMSF) is transmitted by the American dog tick (Dermacentor variabilis), Rocky Mountain wood tick (Dermacentor andersoni), and the brown dog tick (Rhipicephalus sangunineus) in the U.S. The brown dog tick and other tick species are associated with RMSF in Central and South America.
START (Southern tick-associated rash illness) is transmitted via bites from the lone star tick (Ambylomma americanum), found in the southeastern and eastern U.S.
Tickborne relapsing fever (TBRF) is transmitted to humans through the bite of infected soft ticks. TBRF has been reported in 15 states: Arizona, California, Colorado, Idaho, Kansas, Montana, Nevada, New Mexico, Ohio, Oklahoma, Oregon, Texas, Utah, Washington, and Wyoming and is associated with sleeping in rustic cabins and vacation homes.
Tularemia is transmitted to humans by the dog tick (Dermacentor variabilis), the wood tick (Dermacentor andersoni), and the lone star tick (Amblyomma americanum). Tularemia occurs throughout the U.S.
364D rickettsiosis (Rickettsia phillipi, proposed) is transmitted to humans by the Pacific Coast tick (Dermacentor occidentalis ticks). This is a new disease that has been found in California.
Mosquitoes are also known to carry diseases. Examples are the Zika virus, West Nile virus; dengue fever and chikungunya.
The only flea-borne disease in the CDC report is plague, the bacterium responsible for the medieval Black Death. It remains rare but persistent: Between two and 17 cases were reported from 2004 to 2016, mostly in the Southwest. The infection can be cured with antibiotics.
The Asian long-homed tick, Haemaphysalis longicomis, is spreading rapidly along the Eastern Seaboard. It has been found in seven states and in the heavily populated suburbs of New York City.
In the prior art, it is known to use various chemical agents either to repel such insects, or to attempt to kill or otherwise render insects harmless. However, many such chemicals pose their own risks to health. In some cases, such applications require people and pets to remain indoors while the chemicals are applied, often by spraying from vehicles, helicopters or airplanes. Use of chemicals also adds costs, which may be significant. Examples of such chemicals are N, N-Diethyl-meta-toluamide (known as DEET), Icaridin, also known as picaridin, and/or ethyl butylacetylarninopropionate (also known as IR3535).

The foregoing and other objects, aspects, features, and advantages of the invention will become more apparent from the following description and from the claims.
The objects and features of the invention can be better understood with reference to the drawings described below, and the claims. The drawings are not necessarily to scale, emphasis instead generally being placed upon illustrating the principles of the invention. In the drawings, like numerals are used to indicate like parts throughout the various views.
In general, the invention involves providing apparatus and methods by which arthropods are collected, and can be removed from a region of interest, such as a lawn, a playing field, a walking path or trail, and then the arthropods can be neutralized, all of which is accomplished without the deliberate application of hazardous chemicals to the region of interest. The method includes passing a mechanism that may comprise a surface that arthropods preferentially attach themselves to, or a mechanism that provides suction, or both, over the region of interest, allowing the arthropods to attach themselves to the surface or be collected by the suction force, removing the arthropods from the region of interest, and subjecting the arthropods to a neutralizing field such as electromagnetic radiation (UV light, for example). The arthropods may be collected for further analysis by suitable laboratories, for example to count how many (or what percentage of) arthropods are infected with, or are carriers of, various diseases. This can assist health monitoring agencies to determine where (geographically) such infected arthropods are present, and how severe the danger from specific types of arthropods (and the diseases that they are carrying) may be at a given time.
In one embodiment, the present invention comprises an electromechanical device, designed to provide intake pressure, or suction, of parasitic arthropods from grasses, and to collect said arthropods in an aqueous medium, whereby said arthropods are subjected to irradiation, such as from a UVC light source. Said collection system is designed to extract parasitic arthropods from grasses, and to neutralize the harmful bacteria in which they may carry, such as Lyme Borreliosis, Rocky Mountain spotted fever, anaplasmosis, ehrlichiosis, Powassan virus, and or babesiosis; all of which are subject to neutralization through the repeated exposure to an irradiation type light source.
In describing the invention, it will be understood that a number of techniques and steps are disclosed. Each of these has individual benefit and each can also be used in conjunction with one or more, or in some cases all, of the other disclosed techniques. Accordingly, for the sake of clarity, this description will refrain from repeating every possible combination of the individual steps in an unnecessary fashion. Nevertheless, the specification and claims should be read with the understanding that such combinations are entirely within the scope of the invention and the claims.
In a first embodiment, a parasitic arthropod collection system, apparatuses, and methods for collecting and neutralizing parasitic arthropods that carry harmful blood-borne pathogens are discussed herein. In the following description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of the present invention. It will be evident, however, to one skilled in the art that the present invention may be practiced without these specific details.
The present disclosure is to be considered as an exemplification of the invention, and is not intended to limit the invention to the specific embodiments illustrated by the figures or descriptions below.
The first embodiment will now be described by referencing the appended figures representing preferred embodiments.
The first embodiment of the invention may be provided as a device that attaches to a mechanical object such as a riding mower, as illustrated in
The embodiment illustrated in
The device of the second embodiment has an interior structure in the form of a cylinder (which may be hollow or may be solid), and having a pair of end plates that can support a rotational structure aligned along the central axis of the cylinder. The rotational structure may be an axle that extends past each end of the cylinder, and may be constructed of a single axle extending from an exterior surface of the first end plate to an exterior surface of the second end plate, or may be two rotational structures, each one attached to a respective exterior surface of each end plate.
The device of the second embodiment has a handle structure that allows each rotational structure, and the attached cylinder, to rotate while the handle structure is used to propel the roller over a surface, such as by way of example, a grass lawn. The roller can be propelled by a human, or by a mechanical device such as a riding mower.
The roller of
Either the roller embodiment such as illustrated in
The experimental roller was tested in conjunction with a drag mat. The roller provides a preferred medium for some users, as it allows users to “roll” the grass easily, while avoiding snagging the drag mat on small sticks etc. The observed behavior of the ticks is that they will “hunker down” into the synthetic threads while the roller is moving, and once the roller comes to a stop, they will begin to move about within 2-3 minutes. This movement allows for an easier collection of the ticks, as they are no longer hunkered down in between the threads, but they climb atop of the threads, making them easier to acquire.
The drag mat was attached behind the roller to ensure that ticks were preferentially snared in the roller, and that ticks were not missed. In every use of the roller/mat combination to the present time, 100% of the ticks collected were collected by the roller, and none were found on the drag mat. It is possible that if the number of tick was larger, or that if other arthropods of interest were present, that they might be collected on the drag mat.
Traditional tick collection methods often employ a technique referred to as “tick dragging”, whereby a cloth measuring approximately 1 meter by 1 meter, is used to “drag” along the surface of foliage in an attempt to exploit the arthropods “questing” behavior. The nature of “questing” is to facilitate the adherence to a potential host. However this behavior does not afford one the capacity to differentiate between an actual host, or a synthetic material that has the same physical characteristics of a preferred host. The ticks appendages are configured to establish a “snaring” action via tiny “hook like” tips at the ends of their appendages, which help to facilitate adhesion upon the surface of a host. Although this method of “dragging” has been shown to be an effective means of adhering ticks, its very application places the user in danger of becoming a potential host himself.
In order to drag the cloth, the user either walks directly in front of the cloth, or off to one side. In either configuration, the user potentially places himself directly in the pathway of the ticks.
In the present invention, one can avoid this dilemma by “treating” the foliage (or mitigating the number of arthropods) before the user is required to walk through it. One such device is the “roller”, which is propelled by a user, who applies a force via a handle as the user walks behind the device. The roller's surface is further configured to possess a synthetic covering which mimics the arthropods preferred host. The roller reduces exposure of a user to the likelihood of acquiring an arthropod as a result of causing “adherence” of the tick to the synthetic roller prior to the operator passing through the foliage. In this manner, the foliage or grass is “treated” or “swept” prior to the user walking through the foliage or grass. Arthropods exposed to the synthetic material are “tricked” into believing that it is a suitable host, and as a result, will adhere themselves to the material, thereby reducing potential exposure to an operator.
The “rolling” action of the device further reduces the potential of friction, which the “dragging” method suffers from as it is pulled atop of foliage. By dragging a cloth, it is subject to “snaring” upon debris, such as sticks, for which can reduce its effectiveness. Additionally, the frictional force exhorted upon “clinging” ticks as a result of being dragged across foliage may result in the loss of some of the ticks. By applying a roller, the action reduces the likelihood of “snaring” debris as a result of its spinning action, rather than a frictional drag. The ease by which a user can operate the roller, combined with its reduction in exposure to ticks as a user passes through the foliage, make the roller a preferred collection model.
In each of the embodiments, the invention provides that advantage that the user need not come into contact with a surface that has not been treated to mitigate the number of arthropods.
In some embodiments, such as the first embodiment that uses suction to mitigate the number of arthropods, the intake can be place in a location such that the surface is treated to mitigate the number of arthropods is treated before the user reaches and contacts the treated surface. In some embodiments, such as the second embodiment configured as a mechanical roller, the user can walk behind the roller, so that the surface is treated to mitigate the number of arthropods before the user contacts the treated surface. In some embodiments, such as the third embodiment attached to the front of a riding mower, the user rides on a mechanical device and does not touch the surface that is being treated at all.
