  • Fig. 14 is a schematic illustration of a system with multiple units and a common filter, reservoir and pump.
  • a preferred embodiment of the apparatus 1 includes a trap assembly 1 having a drainable basin 2 positionable over a reservoir 3, the reservoir preferably being provided by a container 4.
  • a drain assembly 5 At the bottom of the basin is a drain assembly 5, having a drain opening 6 (see Fig. 3) and suitable means for opening and closing the drain opening, such as a gate or "knife" valve 7 (see Fig. 4).

  • From the drain opening water in the basin can be drained into and through a filter 8 and thence into the reservoir, by opening the gate valve, for example by an operating handle 9 connected to the gate valve by a cable 10, or by any other suitable means, the actual means by which the valve is operated not being critical.
  • the filter captures any unwanted debris and targeted insect eggs and larvae from the water and allows the water and artificial or natural attractants in the water to pass into the reservoir.
  • a gate valve is especially advantageous due to its self-cleaning nature, i.e. any debris or algae buildup is scraped off the gate each time the gate slides open.
  • a cover 11 (see Fig. 2) to provide protection against excessive debris as well as from wind, rain and sun.
  • the cover has large lateral openings for mosquitoes to enter from the side.
  • the water level in the reservoir 3 is maintained below the height of the filter, so that the filter can dry out between times when the basin 2 is drained. Although the environment will be very humid, it will be sufficiently dry that the larvae cannot survive.
  • the specific filter to be used may vary widely, and could be as simple as the pleated type commonly used with swimming pools for example.
  • the filter must allow water to pass freely into the reservoir, but must have pore sizes sufficiently small to trap the insect eggs and larvae while allowing passage of the water and any natural or synthetic attractant present in the water.
  • the filter design preferably does not permit pooling of water at the bottom of the filter housing, so that maturation of the larvae cannot occur there.
  • the filter may be secured by any number of conventional means, such as by positioning it against the drain assembly and rotating it so that the tongue 80 engages studs 81 (see Figs. 6 and 7).
  • the basin 2 can accommodate any suitable liquid that will attract gravid insects to lay their eggs in the liquid.
  • the liquid will be water, preferably supplemented with a chemical attractant or natural chemical cues that attract gravid insects.
  • water is used above and will be used below, but it should be understood that this includes water supplemented with attractants, as well as any other suitable liquids, unless the context indicates otherwise. Juices and other extracts or certain water-based solutions could conceivably be used, for example.
  • the inner surface of the basin 2 is typically concave in shape.
  • the shape of the basin may be varied widely, according to design preference, though its inner surface of the basin should slope towards the drain assembly 5 to facilitate complete draining of the basin when the gate valve 7 is opened.
  • the inner surface should also be as smooth as possible so that eggs and debris do not adhere to it and so that the basin will drain as thoroughly as possible.
  • the apparatus may be supplied with a customized container to act as the reservoir 3.
  • the trap assembly 1 may be dimensioned to fit over a standard container 4, such as a typical 5-gallon bucket or pail. This avoids the need for a customized container and facilitates portability and shipment of the apparatus. It is then sufficient to supply the trap assembly without a container, as long as the purchaser or user has access to a 5-gallon pail or other suitable standardized container to act as the reservoir. In some situations, it may not even be necessary to provide a container. For example, in some situations the reservoir could be in the form of a suitably sized hole in the ground, lined with plastic to prevent leakage, though this may be far from an ideal configuration.
  • the reservoir function could be provided by a container which is not beneath the basin 2, but instead is merely connected by suitable tubing. It is also possible that a container or containment device could be made by local artisans using locally available materials such as brick or stone, mortar, etc..
  • a ring 12 as shown in Fig. 8 can be provided around the upper periphery of the trap assembly 1 or basin 2, the ring having several concentric channels 13 of various diameters, to accommodate a variety of different container sizes.

  • the ring may be provided with an optional gasket (not illustrated) to create an airtight seal between the trap assembly and the container, and/or there could also be a mechanical latch, tab, or other mechanism to create an airtight seal if desired, such as the latch 70 seen in Fig. 10.
  • the ring or a modified version thereof could be placed over a hole or pit dug in the ground or a projection raised from the ground and the trap assembly could then be positioned over the ring. This arrangement is suited to remote installations where containers may not be readily accessible.
  • the trap assembly may be provided with a lifting handle 14 (see Fig. 1) to facilitate lifting the trap assembly 1 from the reservoir 3.
  • the shape, size and colour of the basin 2 may be chosen to assist in attracting an insect to the pool to lay its eggs. For example, it is believed that mosquitoes prefer dark environments to lay their eggs. Accordingly, it may be preferable that the basin be produced in a dark and opaque colour. A dark colour basin would also retain heat, which has also been shown to be an attractant for mosquitoes and other flying insects. If the basin is opaque it may be beneficial to provide a transparent strip down the side of the basin, so that the water level in the reservoir 3 can be visually monitored.
  • the trap assembly also includes a pump 20 which extends down below the level of the filter (which is kept dry as much as possible) into the reservoir 3 to draw water therefrom.
  • the pump may be of any desired form, manual or powered.
  • it can be of the common manual bilge pump variety as illustrated, operated by a pump handle 21, to pump water from the reservoir into the basin 2, or if powered, it could be a submersible 9-volt DC pump, for example.
  • the pump has at least one outlet 22, which may be on the body of the pump itself, but preferably it is plumbed to several outlets 22 so that the inner surface of the basin can be thoroughly rinsed via swirling action.
  • the several outlets 22 can be in any desired location or configuration to effectively rinse the basin, various examples being shown in Figs. 5A to 5D.
  • a compressor or the like could conceivably be used in order to convey the water via differential air pressure within the container.
  • the basin 2 is filled with water to a suitable level, which may be varied as desired according to the different breeding habits and preferences of the various insects that may use the basin as an artificial breeding pool to lay their eggs.
  • the gate valve 7 Periodically, the gate valve 7 is opened to drain the basin through the filter 8, thereby capturing any eggs which have been laid on the water surface in the basin.
  • the pump 20 is then operated to rinse the basin thoroughly, to wash any eggs or other debris from the basin down into the filter.
  • the gate valve 7 is operated to close the drain, and the pump is operated to refill the basin to the desired level.
  • mosquitoes may choose the water in the basin as their breeding location.
  • the performance of the apparatus is very significantly enhanced by employing means to specifically attract the mosquitoes.
  • Several means may be used to attract the mosquitoes, either separately or preferably in combination.
  • the water in the basin 2 and/or in the reservoir 3 may be spiked with a liquid chemical attractant, such as those described in US Patent Publication No. 2008/0003197, which acts as chemical cue for gravid insects to lay their eggs in the water.
  • FIG. 3 Another alternative uses a floating assembly 25 in the basin, as seen in Figs. 1 , 3 and 4.
  • this assembly includes a lower compartment filled with StyrofoamTM or the like (or air) sufficient for the assembly to float on the surface of the water.
  • the assembly also has an upper compartment, with a hinged lid.
  • the assembly is connected to a track 26 via a U-bar 27, which can slide up and down in the track according to the water level in the basin.
  • a replaceable puck of attractant material can be placed in the upper compartment, to gradually exude attractants over an extended period of time from openings which could be along the top as shown in Fig. 3, or partially along the top, or from open ports near opposite ends of the assembly.
  • a slow-dissolving attractant composition could be deposited in the water in puck form, or in a tea-bag-like dispenser, whether in the basin 2 or in the reservoir 3.
  • a particularly advantageous attraction involves chemical cues which are released from the floating assembly into the water of the reservoir, in combination with natural chemical cues, such as pheromones naturally released by the mosquitoes when they breed successfully. These volatile natural chemical cues accumulate in the reservoir when the water is drained from the basin, since they form part of the aqueous phase within the container. Periodically releasing these pheromones from the reservoir can act as powerful mosquito attractants.
  • the upper edge of the basin 2 is preferably provided with a number of vents 30, as best seen in Figs. 1, 3, 6 and 9, which are open into the reservoir.
  • the reservoir otherwise is preferably sealed, so that air can escape only via the vents.
  • the vents are openable and closable, so that they may be opened only at peak hours, rather than "wasting" the pheromones in daytime or windy conditions.
  • a shutter mechanism such as a slider 31 may be positioned behind the vents 30, configured such that moving the slider blocks or uncovers the vents.
  • the slider could have apertures which either align with the vents, or block them, depending on the position of the slider.
  • the slider could be manually operated, or for automated versions, a small motor 32 may be used to operate it, powered by the battery pack 33.
  • a small motor 32 may be used to operate it, powered by the battery pack 33.
  • Each successive cycle of draining the basin through the filter and then replenishing from the reservoir increases the concentration of attractants in the water, both natural and synthetic. More water may need to be added from time to time if the concentration of attractants becomes excessive, or if the water level drops due to evaporation.
  • a small fan 35 may be provided, preferably but not necessarily mounted to the trap assembly 1 rather than the container, and preferably but not necessarily near the vents 30, to assist in forcing the gas through the vents 30. This fan will also assist in the drying of the filter after the water has been passed through, to increase the efficiency of the system.
  • the fan should be timed to operate only when peak attraction is desired, rather than continuously, since continuous operation would significantly reduce the attractant effect, as well as potentially producing excessive evaporation of the water in the reservoir 3 and draining the battery
  • the container may be slightly pressurized prior to the opening of the vents 30, using a compressor or other means, provided that the container is airtight or relatively so.
  • a screen may be provided above the waterline of the container with a mesh size capable of preventing the passage of mosquitoes.
  • a mesh size capable of preventing the passage of mosquitoes.
  • Another attracting means is to use light emitting and/or light reflecting sources in the vicinity of the basin, such as light from a light or light pack 34 (see Figs. 1 and 4). These light sources may be in a single or multiple frequency arrangements, in accordance with known criteria for the target insect. Yet another attracting means is to place a filter in front of the light source, so as to create polarized light. In order to minimize the energy requirements of the apparatus, light emitting diodes (LEDs) are preferred as the light emitting source due to their low power consumption. However, any type of light emitting source shown to attract gravid insects will work with the apparatus.
  • LEDs light emitting diodes
  • any number of light reflecting sources can be used with the apparatus, including, but not limited to, reflective foils and the like, in order to reflect both ambient light sources, such as the moon or sky, or internal sources.
  • Fig. 3 shows the use of reflective strips 32, for example.
  • Power for the fan and/or LEDs may be supplied from a battery pack 33 (see Fig. 9), preferably rechargeable, from plugging into a power source if available, or ideally from a battery pack recharged by a small solar panel suitably positioned outside the apparatus, whether secured thereto or as a separate component.
  • a battery pack 33 see Fig. 9
  • a small solar panel suitably positioned outside the apparatus, whether secured thereto or as a separate component.
  • Another possible variation, to further enhance the effectiveness of the apparatus in attracting gravid insects which prefer not to lay their eggs directly on a water surface, is to provide an upper portion of the basin 2, and/or at least a portion of the upper surface of the floating unit 25, with an egg laying medium, such as germination paper 36 (see Fig. 3) or any other porous material that can hold humidity.
  • an egg laying medium such as germination paper 36 (see Fig. 3) or any other porous material that can hold humidity.
  • the germination paper is positioned so as to have a portion which contacts the water in the basin, so that water wicks to keep the germination paper moist.
  • the germination paper may be rinsed thoroughly by water from the outlets 22 from the pump 20, or may be suitably disposed of from time to time, weekly for example, or destroyed, for example by burning.
  • the container may be desirable to construct the container from a material with a low albedo value, which will more rapidly heat up the water compared to light coloured material. This may be especially desirable in cooler locations, to create a warmer, moist environment to appeal to the mosquitoes.
  • a customized container 4 with an access door, for example a swing-out door 40 as shown in Fig. 10.
  • the filter may rest on a platform 41 extending inwardly from the door, such that swinging the door inwardly moves the filter into its proper operating position against a flange below the drain assembly 5 and drain opening 6.
  • Another possible variation is to connect multiple units to each other.
  • a system of interconnected units can be provided to enhance the ability restrict the maturation of aquatically hatched insects over a geographic area. This is illustrated in Fig. 11 , showing just two units as an example.
  • the reservoirs are connected via a hose 50 attached to connectors 51.
  • a pump (not shown) can be connected to circulate the water between the multiple reservoirs periodically, either by manual operation, or under electronic control.
  • each unit could have its own reservoir, with a pumping system circulating the water through the various connected units, or as shown in Fig. 14 there could be one or more central reservoirs 3 to which water from the various basins 2 is routed after passing through the valve assemblies 5 and their valves. The filtration could take place at each unit, or as shown in Fig. 14, there could be a centralized filter 8 instead.
  • one container placed in a cool area will most certainly augment the value of the use of this system, i.e. there can be a common reservoir in a cool area for a number of units, not associated with any one unit in particular but interconnected with all of the units.
  • Figs. 12A to 12C show an alternative configuration for the apparatus.
  • a container 4 provides the reservoir, and the basin 3 is defined by a depression in an upper piece which mates with the container.
  • this configuration can be nested to a fair degree to facilitate shipping and/or end of season storage. Of course for shipping, the filter 8 would normally be removed as well.
  • This configuration also does not required a container that is as deep, since the basin does not sit down in the container as in the other embodiments. This reduced container size reduces mold costs, and in general is easier to handle.
  • the various embodiments described above can be operated entirely manually.
  • a user may set the trap once, and the electronic controller will actuate the system on a pre-programmed sequence, only requiring periodic maintenance to add water and/or attractant, and to clean or replace the filter.

Abstract

L'appareil selon l'invention comprend une cuvette qui peut être vidangée (2) et qui contient un liquide, en général de l'eau, auquel ont été ajoutées de préférence une ou plusieurs substances attirant les insectes. La cuvette comporte un système de vidange (6) dans sa partie inférieure qui est ouvert et fermé au moyen d'une vanne (7). Le système de vidange mène à un filtre (8) qui élimine les œufs et les larves du liquide lorsque la cuvette est vidée suite à l'ouverture de la vanne. Le liquide passant par le filtre est recueilli dans un réservoir (3) d'où il peut être réinjecté dans la cuvette. L'appareil utilise de préférence plusieurs récipients standard, le récipient (4) pouvant ensuite servir de réservoir. Une ou plusieurs substances attirant les insectes, notamment les substances chimiques et la lumière, ainsi que les substances naturelles, sont de préférence utilisées. Le réservoir comporte des orifices d'aération (30) et contient des substances attractives concentrées qui sont libérées dans la cuvette au moyen desdits orifices. Deux unités ou plus peuvent disposer de réservoirs reliés les uns aux autres, ou peuvent partager un réservoir commun. Le principe de fonctionnement de l'appareil est le suivant : la cuvette est remplie d'un liquide auquel ont été ajoutées de préférence une ou plusieurs substances attractives, le liquide restant dans la cuvette pendant un laps de temps suffisant pour que les œufs et les larves s'accumulent, mais pas assez longtemps pour qu'elles deviennent adultes. La cuvette est ensuite vidangée, le liquide étant filtré dans le réservoir. La cuvette est ensuite de nouveau remplie avec le liquide filtré provenant du réservoir, et le cycle recommence. L'appareil peut éventuellement être automatisé et le procédé peut être effectué automatiquement en ne nécessitant qu'un entretien régulier.
