Technical Field
[0001] This utility model relates to a tool for attracting pregnant female mosquitoes in the wild, belonging to the technical field of mosquito attracting tools. Background Technology
[0002] Mosquitoes are major vectors for infectious diseases such as dengue fever, malaria, yellow fever, and Zika virus, especially in tropical and subtropical regions where mosquito populations are abundant, where excessive mosquitoes pose a significant threat to public health. Pregnant female mosquitoes, which are female individuals preparing to lay eggs after feeding on blood, often carry pathogens such as dengue virus and malaria parasites, and are the primary vectors for disease transmission. Trapping pregnant female mosquitoes is crucial for disease control, as they pose a greater risk of transmission compared to mosquitoes at other stages. Trapping and eliminating these individuals can effectively interrupt the transmission chain and significantly reduce the reproductive capacity of mosquito populations, thus reducing the number of the next generation of mosquitoes at the source. Furthermore, monitoring pregnant female mosquitoes reflects disease transmission potential and mosquito density, serving as an important means of assessing epidemic risk and guiding control strategies. Therefore, trapping pregnant female mosquitoes is a precise, efficient, and sustainable measure for mosquito-borne disease control.
[0003] Currently, the most common method for attracting pregnant female mosquitoes in the wild is through oviposition traps. These traps use black containers that simulate stagnant water environments and oviposition attractants to attract pregnant female mosquitoes to lay their eggs, which are then captured using adhesive or other methods. To cater to the mosquitoes' habit of seeking out water surfaces or near water edges to lay their eggs, the openings of the black containers are generally designed to face upwards. This allows the mosquitoes to land directly in the trap after flying through the air, reducing entry barriers and increasing the capture rate. Furthermore, the upward-facing opening facilitates the diffusion of the attractant scent, covering a wider area. However, oviposition traps with upward-facing openings are frequently exposed to thunderstorms in the wild, causing rainwater to enter the black containers. While overflow holes at a certain height in the container prevent this from filling the container, the oviposition attractant still leaks out, excessively diluting its concentration and reducing its effectiveness.
[0004] Therefore, in order to improve the efficiency of attracting pregnant female mosquitoes, there is an urgent need for a field tool for attracting pregnant female mosquitoes that can keep the opening facing upwards while automatically draining the rainwater that is poured in, and prevent the oviposition attractant from being lost through the overflow hole, so as to be able to attract mosquitoes efficiently in the field for a long time. Summary of the Invention
[0005] The technical problem to be solved by this utility model is to provide a field-based tool for attracting pregnant female mosquitoes, which solves the problem that the oviposition attractant is lost and the mosquito-attracting effect deteriorates when the current field-based attractants for pregnant female mosquitoes are flooded by rainwater.
[0006] The technical problem to be solved by this utility model is achieved by the following technical solution:
[0007] A tool for attracting pregnant female mosquitoes in the wild, comprising:
[0008] The container includes a barrel with an opening at the top and a lid with a hollow hole that closes the opening.
[0009] The attracting tube has a hollow hole installed in the middle of its outer wall. The top of the attracting tube is provided with a funnel-shaped attracting channel that is wider at the top and narrower at the bottom. The bottom of the attracting tube is fixed with a mesh plate to prevent mosquitoes from escaping. The inner wall of the attracting tube is fitted with a trapping sleeve for sticking mosquitoes.
[0010] A flow guide is provided directly below the funnel-shaped attracting channel. The flow guide catches the water flowing down from the bottom of the funnel-shaped attracting channel and directs the water flow outside the barrel.
[0011] Preferably, the guide includes a water receiving hopper, which is fixed to the bottom of the barrel and the interior of the water receiving hopper is in communication with the exterior of the barrel.
[0012] Preferably, the guide component further includes a drain pipe and a float valve. One side of the water receiving hopper is fixed to the bottom of the bucket body through the drain pipe. The drain pipe connects the water receiving hopper to the outside of the bucket body, and the float valve is installed at the bottom of the water receiving hopper.
[0013] Preferably, the top of the funnel-shaped trapping channel is provided with a mesh cover that allows mosquitoes to pass through.
[0014] Preferably, an outwardly expanding fixing ring is provided in the middle of the outer wall of the trapping tube. The fixing ring seals the gap between the trapping tube and the hollow hole, and restricts the trapping tube from descending further.
[0015] Preferably, the fixing ring and the top cover are fixed by magnetic attraction.
[0016] Preferably, the capture sleeve is a plastic sleeve with adhesive coated on its inner wall.
[0017] Preferably, the mesh plate is screwed to the bottom of the trapping cylinder, and the trapping sleeve is confined within the trapping cylinder by the mesh plate.
[0018] Preferably, the barrel body is a foldable barrel body that can be folded inward.
[0019] Preferably, the bottom circumference of the barrel is provided with supporting feet.
[0020] The beneficial effects of this utility model are:
[0021] 1. The liquid containing the oviposition attractant is poured into the barrel to simulate a stagnant water environment, attracting pregnant female mosquitoes to lay eggs. The mosquitoes are then led in through the funnel-shaped trapping channel of the trapping tube and are difficult to escape. The trapping snare then traps the mosquitoes, thus achieving the purpose of trapping. The mesh can restrict the mosquitoes to move within the trapping tube, increasing the chance of them being trapped.
[0022] 2. Based on this, a water collection hopper was added to work in conjunction with the funnel-shaped trapping channel. The water collection hopper can drain the rainwater from the top of the bucket, preventing the oviposition attractant from being lost and maintaining a high mosquito-attracting effect in the wild for a long time.

[0035] To facilitate a clear understanding of the technical means, creative features, objectives, and effects of this utility model, the following description, in conjunction with specific illustrations, further elaborates on this utility model.
[0036] like Figure 1 , Figure 4 As shown, this field tool for attracting pregnant female mosquitoes includes a black container 1, a black attracting tube 2, and a flow guide 3 located in the container 1.
[0037] Container 1 is a flexible, conical barrel 101 made of rubber or plastic, with an opening at the top. The flexible barrel 101 can be folded for easy carrying. The bottom is squeezed inward to form a folding barrel structure. The top cover 102 is a plastic cover, which is fixed to the opening of the barrel 101 by screws or snaps, and has a hollow hole 103 in the middle.
[0038] like Figure 2 , Figure 3 As shown, the trap 2 is a black plastic barrel 101. An outwardly expanding retaining ring 201 is provided in the middle of the outer wall of the trap 2. The trap 2 is inserted into the hollow hole 103. The retaining ring 201 seals the gap between the trap 2 and the hollow hole 103, and restricts the trap 2 from descending further. The trap 2 can be fixed to the hollow hole 103 by an interference fit, or by magnetic blocks that attract each other on the retaining ring 201 and the corresponding position on the top cover 102, thus fixing the trap 2 to the top cover 102. This design facilitates the removal of the trap 2 from the container 1 when cleaning up mosquito carcasses, making it easy to replace the trap sleeve 203 and clean the container.
[0039] The bottom of the trap 2 is fixed with a mesh plate 202 to prevent mosquitoes from escaping. The inner wall of the trap 2 is fitted with a trapping sleeve 203 for trapping mosquitoes. The mesh plate 202 restricts the movement of mosquitoes within the trap 2, increasing the probability of mosquitoes being trapped by the trapping sleeve 203. This allows mosquitoes and their corpses to be concentrated inside the trap 2, making them easy to remove and clean.
[0040] like Figure 4 As shown, in some embodiments, the guide 3 is located directly below the funnel-shaped attracting channel 204. The guide 3 catches the water flowing down from the bottom of the funnel-shaped attracting channel 204 and directs the water flow out of the barrel 101. The guide 3 includes a water receiving hopper 301, which is fixed to the bottom of the barrel 101 and is connected to the outside of the barrel 101.
[0041] When rainwater flows into the container 1 through the funnel-shaped attractant channel 204, the water is caught by the water collection hopper 301 after passing through the mesh plate 202, instead of directly entering the barrel 101, thus preventing the loss of the spawning attractant. The water in the water collection hopper 301 is discharged from the bottom of the barrel 101. Support feet 104 are provided on the circumference of the bottom of the barrel 101, which elevates the barrel 101, making it easier for the water discharged from the barrel 101 to spread outwards.
[0042] like Figures 5-7 As shown, in some embodiments, the guide 3 also includes a drain pipe 302 and a float 3031 valve 303. One side of the water receiving hopper 301 is fixed to the bottom of the bucket 101 through the drain pipe 302. The drain pipe 302 connects the water receiving hopper 301 to the outside of the bucket 101. The float 3031 valve 303 is installed at the bottom of the water receiving hopper 301. The float valve 303 includes a float 3031, a connecting rod 3032, a hollow bracket 3033, a guide sleeve 3034, and a conical valve core 3035. The bottom of the water receiving hopper 301 is provided with a conical opening 3011 that is smaller at the top and larger at the bottom. The guide sleeve 3034 is fixed to the upper part of the conical opening 3011 by the hollow bracket 3033. The connecting rod 3032 is inserted into the guide sleeve 3034. A limiting ball 3036 is provided at the top of the connecting rod 3032. The diameter of the limiting ball 3036 is larger than the inner diameter of the guide sleeve 3034. The float 3031 is fixed at the bottom of the connecting rod 3032. The conical valve core 3035 is fixed on the connecting rod 3032. The conical valve core 3035 is located below the conical opening 3011 and cooperates with the conical opening 3011.
[0043] Summer's abundant rainfall is ideal for mosquito breeding, but it also makes existing female mosquito traps prone to water ingress, leading to the loss of oviposition attractant and reduced effectiveness. To address this issue, a certain amount of liquid containing oviposition attractant is poured into the trap body 101. The upper limit of the liquid level is called the upper limit height. The working principle of this trap's water replenishment and anti-over-dilution mechanism is as follows:
[0044] (1) Insect attraction: When it does not rain, the liquid level inside the tank 101 will gradually drop below the upper limit due to the evaporation of water and the diffusion of odor. At this time, under the action of gravity, the float 3031 valve 303 is normally open.
[0045] (2) Water replenishment: When it starts to rain, because the liquid level in the tank 101 is lower than the upper limit height, the float 3031 valve 303 is in the normally open state (e.g., Figure 6As shown), at this time, the water in the water receiving hopper 301 will fall into the bucket 101 (the drain pipe 302 is connected to one side of the water receiving hopper 301, which is located at a higher position, so rainwater will fall into the bucket 101 from the bottom first), replenishing the liquid of the oviposition attractant in the bucket 101. When replenishing the water, the oviposition attractant will not overflow out of the bucket 101, ensuring that the remaining oviposition attractant can still play a good oviposition attraction effect.
[0046] (3) Blocking: When the liquid level inside the tank 101 is equal to or higher than the upper limit height, the float 3031 valve 303 will block the bottom of the water inlet 301 (e.g. Figure 7 As shown), the water in the water inlet 301 will be discharged out of the tank 101 along the drain pipe 302. While the guide component 3 plays a role in replenishing water, it can stop replenishing water when the liquid level reaches the upper limit value to prevent the loss of the oviposition attractant, so that the attracting tool can carry out mosquito attracting work in the field for a long time without worrying about rain damage.
[0047] like Figure 1 , Figure 4 As shown, in some embodiments, the top of the horn-shaped trapping channel 204 is provided with a clogging mesh cover 4 that allows mosquitoes to pass through.
[0048] In the wild, the anti-blocking mesh cover 4 can prevent debris such as branches and fallen leaves from entering the funnel-shaped trapping channel 204 and prevent the narrow part at the bottom of the funnel-shaped trapping channel 204 from being blocked. The always unobstructed funnel-shaped trapping channel 204 can make it easier for pregnant female mosquitoes to enter and be trapped.
[0049] In some embodiments, the capture sleeve 203 is a plastic sleeve with adhesive coating on its inner wall. The mesh plate 202 is screwed to the bottom of the trapping cylinder 2, and the capture sleeve 203 is confined inside the trapping cylinder 2 by the mesh plate 202.
[0050] The plastic sleeve with adhesive coating on the inner wall is a convenient fixing structure that allows for easy removal and replacement of the plastic sleeve from the trapping tube 2.
[0051] During field patrols, if the oviposition attractant is insufficient, water and oviposition attractant can be added to container 101. Once the adhesive is saturated, the trap 203 can be replaced. Then, continue the trapping of pregnant female mosquitoes.
[0052] In some embodiments, the barrel 101 is a foldable barrel 101 that can be retracted. Since multiple trapping tools are typically needed in the field, using a foldable barrel 101 helps reduce transport space and allows more trapping tools to be carried at once.
[0053] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of protection claimed by this utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
