This invention relates to insect traps, and in particular to systems, devices, and methods for using insect traps with combinations of dual multi-colored lights combining blue/green LED (light emitting diodes) with UV (ultraviolet) LEDs (light emitting diodes) for attracting insects to the lights and capturing the insects.
Insect traps using UV (ultra violet) LED (light emitting diodes) lamps have been proposed over recent years. See for example, U.S. Pat. No. 9,706,764 to Koo et al.; U.S. Pat. No. 9,717,228 to Koo et al.; and 9,832,986 to Koo et al., which are incorporated by reference.
The UV (ultra violet) LED (light emitting diodes) in these devices are generally limited to wavelengths of between 335 to 395 nm, and do not cover other wavelengths visible to insects needed for attracting insects.
Attempts have been proposed to use LED (light emitting diode) groups having different wavelengths for attracting insects. See U.S. Pat. No. 10,986,828 to Studer et al. and U.S. Published Patent Application 2018/0184635 to Stud et al., which are both incorporated by reference.
The Studer et al. patent requires a translucent tubular sleeve around the LEDS which acts as a filter to limit and cut-down on the light transmission rays from the LEDs.
The Studer et al. published patent application limits the field by placing the LEDs into of a housing having narrow aperture openings which further limits the direction and spread of light passing from the LEDs.
Japan patent 2016 208944 to Maya Arakane describes a simple device for emitting a mixed wave of ultraviolet visible light that appears to require a cover 4/5 that would further inhibit the light rays and spread from the LEDs (light emitting diodes.
LEDs emit light in a very narrow pencil thin width of light. Insects do not fly directly along a line to the light source.
LEDs produce mainly monochromatic light, meaning that the wavelengths of light are produced in a narrow nanometer range. For this reason, fluorescent bulbs are usually used in light traps. Those fluorescent bulbs produce light in broad bands. But fluorescent bulbs need to be replaced often because the UV output shifts.
Not all the attractive wavelengths of light are in the ultraviolet. So, UV light traps are not as effective as those with broad light output.
Mosquito mesh on cages that catch mosquitoes allow sand flies to escape. The sand fly is really small and it can squeeze through mosquito mesh. The current technologies do not capture sand flies.
Light provided by LEDs is usually pinpoint so insects cannot follow it into the trap.
Thus, the need exists for solutions to the above problems with the prior art.
Our invention spreads the light from the LEDs so insects can follow the light to the source (trap). Most LED light sources are directional and do not attract insects in a close to 360 degree area around the trap. The orientation of our LED plus the spread of light attracts insects from a wider area.
A primary objective of the present invention is to provide systems, devices, and methods for using an insect trap with combinations of dual multi-colored lights combining blue/green LED (light emitting diodes) with UV (ultraviolet) LEDs (light emitting diodes) for attracting insects to the lights and capturing the insects.
A secondary objective of the present invention is to provide systems, devices, and methods for using an insect trap with combinations of dual multi-colored lights combining blue/green LED (light emitting diodes) with UV (ultraviolet) LEDs (light emitting diodes) on a module without any lens, covers or other materials for inhibiting light emissions from the LEDs, for attracting insects to the lights and capturing the insects.
A third objective is to spread the light so there is a uniform beam that covers a wide area around the lights in the trap.
A fourth objective is to orient the wide beams of light so an almost 360 degree of light surrounds the trap to attract the most insects.
The light receptors in the mosquito and other flying insect eyes are broad and extend over a wider range of wavelengths than produced by LEDs.
The muliticolor light trap utilizing UV and Blue LEDs extends the produced wavelengths to those more closely aligned with the wide range light receptors of the insect eye.
Blending the attractive colors of UV and blue improves light trap performance by increasing provided light across the attractive wavelengths.
The approximately 340 micron mesh retains the sand fly (biting midge or noseeum) without inhibiting the suction provided by the fan. Capture of sand flies in our trap is increased by more than 99% by using the approximately 340 micron mesh screen>.
Our LEDs give a 120 degree spread of light so insects can follow the light to the trap.

In this embodiment a centrally located blue-green LED (light emitting diodes) 1 can be located on opposite sides of the module/fixture 4. The blue-green LED can emit light between approximately 45 nm to approximately 550 nm. To each side of the blue-green LED 1 can be at least two or more UV (ultraviolet)-LED (light emitting diodes) each have a wavelength of approximately 365 nm.
Each of the LEDS 1, 2 can include novel lens on the emission side of the LEDs that would not cut down on the intensity of the light
As described above, U.S. Pat. No. 9,706,764 to Koo et al.; U.S. Pat. No. 9,717,228 to Koo et al.; and 9,832,986 to Koo et al., which are incorporated by reference.
The UV (ultra violet) LED (light emitting diodes) in these devices are generally limited to wavelengths of between 335 to 395 nm. However, these limited wavelengths would clearly limit the visible light wavelength attractive to insects.
A publication, Muir et al., Aedes aegypti (Diptera: Culicidae) Vision: Spectral Sensitivity and Other Perceptual Parameters of the Female Eye, J. Med., Entomol, pages 278-281, 1992. The Muir paper teaches us that mosquito eyes are capable so detecting light over a wide range of wavelengths (nm). It does not teach us which wavelengths are preferred or cause aversion. Our optimized trap would utilize ultraviolet and blue-green light to attract more insects than either color alone.
Each of the LEDS 1, 2 in
The LEDs 1, 2 and/or different arrays of LEDs can be individually tunable to different selected wavelengths for both different insects and different species as needed.
The tunable LEDs can be accomplished by various techniques, such as those shown and described in U.S. Pat. No. 6,357,889 to Duggal et al., which is incorporated by reference.
Power for the LEDs can be supplied through wall plug power sources, such as 110, 220 volts, and the like. Possible battery power sources can be used.
Overlapping light spread 110 can be seen from each LED on one side of module. Overlapping light spread 20 can be seen from each LED on opposite side of module.

All the embodiments allow for overlapping light spreads from the LEDs on both sides of the module/fixture.
While the above
The various colors of lights do not have to be with the blue-green LED in the center. Also, the ratio of blue-green to ultraviolet LEDs could differ depending on the target species of insect.
A suction fan 55 can further pull insects attracted to multi-colored lights 1, 2 within a protective cover, and a screen capture cage 56 can capture the dead carcasses of the insects.
During experiments, a fine mesh bag 7 was used with an approximately 340 micron mesh bag wrapped around a cage. The mesh bag caught approximately 39,700 sand flies in a couple of nights. Using only the cage only approximately 500-700 sand flies were captured.
The approximately 340 micron mesh bag allowed the trap to capture biting, tiny, sand flies (biting midges). In a one week period a trap with standard mesh screening to contain mosquitoes only caught approximately 300 to approximately 400 sand flies. When an approximately 340 micron mesh bag was placed over the screened cage, it caught approximately 40,000 sand flies. In other words, the mesh bag improved sand fly catch by more than 99%.
The 340 micron mesh can be placed as a bag over an existing cage to convert the light trap from capturing only mosquitoes to also include sand flies, or the mesh can replace the mesh on the cage to capture both sand flies and mosquitoes.
A bug zapper having an electrically conductive grill with alternating positive and negatively charged electric wires 64 can have a module/fixture 100(from
Insects attracted to the LEDs 1, 2 on the module/fixture 100 can be killed by the electrical grill of wires 64 and collected in a trap 65 underneath.
From Jul. 26, 2021 through Aug. 11, 2021, the subject inventors performed a field trial was conducted in Vero Beach, Fla. to compare the results of different light traps. The initial night of installation was Jul. 25, 2021, and the traps were removed from the field on Aug. 12, 2021. Data was collected over 12 days and included overall biomass (grams) of arthropods caught in each trap and the number and species of mosquitoes caught per trap.
There were 4 trap types in the study as follows:
The SV+B is the multicolor mosquito light trap. Overall, the traps caught 19 different species in 6 different genera. The CDC traps caught fewer species than the other traps (10 species), but the rest of the traps showed no differences with the SV traps and the DT traps catching 12.3 and 13 species, respectively. The number of mosquitoes caught by the different traps was different with the SV Blue Light trap catching the most mosquitoes on 8 of the 12 nights of the trial. Traps also collected non-mosquito arthropods, called by-catch. The CDC traps caught no by-catch, but the other traps caught between ca. 200-300 grams of by-catch over the course of the trial. SV Blue Light caught the most by-catch followed by SV Original and then DynaTrap.
