Description

Technical Field

[0001] This utility model relates to the field of insect trap technology, specifically to a biodegradable insect trap for pine wilt disease vector insects. Background Technology

[0002] Since pine wilt disease occurred in northern my country in 2016, the State Forestry Administration and designated testing laboratories have isolated and identified Korean pine as the natural host of pine wilt nematode for the first time in my country, and spruce longhorn beetle as the effective vector of pine wilt nematode. Therefore, the prevention and control of this type of insect is particularly important.

[0003] A search revealed existing technology (publication number: CN216147063U), which describes "an insect vector trap for blocking the spread of pine wilt disease, comprising a trapping assembly and a collection bottle. The trapping assembly includes multiple trapping sections, a first connecting rod, a hood, and a canopy. Each trapping section is fixedly connected by the first connecting rod and is coaxially spaced. Each trapping section includes a trapping tube, a first air guide plate, and a second air guide plate, all fixedly connected. The first air guide plate is recessed downwards near the trapping tube. The collection bottle is connected to the trapping tube of the lowest trapping section. The hood is connected to the trapping tube of the highest trapping section. The canopy is located above the hood. A second connecting rod is installed between the canopy and the uppermost trapping section. A hanging ring is installed on the canopy. A lure is installed inside the trapping tube of the uppermost trapping section, which solves the problem of poor diffusion of the lure's odor in current traps, resulting in ineffective attraction."

[0004] While existing insect vector traps for blocking the spread of pine wilt disease have achieved the effect of odor diffusion and trapping, they still have some shortcomings: there are many gaps between the upper and lower parts of the trapping segments, making it difficult to ensure that pests crawl downwards into the collection bottle. At the same time, pests that crawl into the collection bottle may also crawl out. Secondly, the hanging rings involved cannot guarantee the stability of the entire trap, causing it to sway and be damaged by the wind in windy weather. Utility Model Content

[0005] To overcome the shortcomings of existing technologies, a biodegradable insect trap for pine wilt disease is provided to address the problems mentioned in the background.

[0006] To achieve the above objectives, a biodegradable insect trap for pine wilt disease is provided, comprising: a trap body, with fixing components connected to both ends of the upper side of the trap body, a trapping hole on the upper surface of the trap body, and an inner cavity connected to the lower end of the trapping hole, plastic barbs connected to the inner wall of the trapping hole, a connecting ring on the lower side of the trapping hole, and a lure rod connected to the lower end of the connecting ring, an external threaded ring on the outer side of the bottom of the inner cavity, and a collection can screwed to the outer side of the external threaded ring, with an insecticide inside the collection can, the fixing components including a sleeve, the lower end of the sleeve being fixedly connected to the upper side of the trap body, and a telescopic rod slidably connected to the upper end of the sleeve, with a clamping block hinged to the upper end of the telescopic rod.

[0007] Furthermore, the main body of the trap is designed as a rectangular structure, and through air holes are provided inside the main body of the trap and between adjacent trapping holes.

[0008] Furthermore, the plastic barbs are arranged along the circumference of the trapping hole, and the plastic barbs are a hollow cone structure.

[0009] Furthermore, a fluorescent lamp is embedded in the inner wall of the trapping hole, and the fluorescent lamp is controlled by a photovoltaic panel power supply and a light control switch.

[0010] Furthermore, the bottom of the connecting ring is provided with an insertion hole, and the lure rod is fixed to the insertion hole by a locking block connected at the upper end, and the bottom of the lure rod extends into the collection tank.

[0011] Furthermore, the upper end of the sleeve is screwed with a locking bolt, and the locking bolt is in contact with the outer wall of the telescopic rod.

[0012] Furthermore, the clamping block is designed as an arc-shaped block structure, and a locking block is connected to the upper end of the clamping block, and the locking blocks are connected to each other by bolts and nuts.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. When in use, the main body of the trap is fixed in the forest by the clamps and locking blocks included in the fixing components. During the fixing process, the height of both ends of the trap body can be adjusted by the telescopic rod and sleeve. The fixed trap body can increase stability in windy weather. The wind holes can reduce the resistance of strong winds, which further increases the stability of the installed trap body and prevents it from swinging and causing damage.

[0015] 2. The fluorescent light and lure inside the trap hole are used to lure pests into the trap hole. The pests then pass through the plastic barbs and enter the inner cavity. They then enter the collection container along with the lure. When the pests come into contact with the insecticide in the collection container, they can be killed in a short time. At the same time, pests that do not enter the collection container are blocked by the plastic barbs and cannot fly out of the trap hole, thus improving the effectiveness of the trap.

[0021] Reference Figures 1 to 4 As shown, this utility model provides a biodegradable insect trap for pine wilt disease vectors, comprising: a trap body 1, with fixing components 2 connected to both ends of the upper side of the trap body 1, and a trapping hole 12 opened on the upper surface of the trap body 1, with an inner cavity 15 connected to the lower end of the trapping hole 12, plastic barbs 13 connected to the inner wall of the trapping hole 12, a connecting ring 16 provided on the lower side of the trapping hole 12, and a lure rod 17 connected to the lower end of the connecting ring 16; an external threaded ring 18 provided on the outer side of the bottom of the inner cavity 15, and a screw threaded onto the outer side of the external threaded ring 18. The collection tank 19 contains an insecticide 191. The fixing component 2 includes a sleeve 21, the lower end of which is fixedly connected to the upper side of the trap body 1. A telescopic rod 23 is slidably connected to the upper end of the sleeve 21. A clamping block 24 is hinged to the upper end of the telescopic rod 23. A locking bolt 22 is screwed to the upper end of the sleeve 21 and contacts the outer wall of the telescopic rod 23. The clamping block 24 is an arc-shaped block structure, and a locking block 25 is connected to the upper end of the clamping block 24. The locking blocks 25 are connected to each other by bolts and nuts.

[0022] In this embodiment, the internal structure of the trap body 1 and the external fixing component 2 constitute the biodegradable pine wilt disease vector insect trap involved in this application.

[0023] It should be noted that the collection container 19 needs to be checked regularly. After opening, the insect bodies inside should be directly introduced into the soil to achieve natural degradation. Secondly, the dosage and toxicity of the insecticide 191 used can be appropriately selected so that it can be used selectively without damaging the soil quality. Of course, insecticide 191 can also be left unused.

[0024] It should be noted that the pests trapped in this application are the same as those in the prior art documents, namely the spruce flowering longhorn beetle, which is the vector of pine wood nematode.

[0025] Specifically, by setting the clamping block 24 to be hinged to the telescopic rod 23, the connection angle between the clamping block 24 and the telescopic rod 23 can be changed during installation, and the two clamping blocks 24 can be tilted to clamp and connect to tree branches or twigs in the rainforest.

[0026] It should be noted that the main body 1 of the trap does not necessarily have to be installed horizontally, but can also be installed at an angle (in order to adapt to different installation environments). However, when insecticide 191 is present, attention should be paid to the liquid level of insecticide 191 and the angle of tilt.

[0027] It should be noted that a rain shelter is provided on the upper side of the trap body 1 and between the fixing components 2 to prevent rainwater from entering the trap hole 12.

[0028] like Figure 1 , Figure 2 and Figure 4 In the trap, the main body 1 is rectangular, and the trap body 1 has through air holes 11 inside and between adjacent trap holes 12. Plastic barbs 13 are arranged along the circumference of the trap holes 12, and the plastic barbs 13 are hollow cones. Fluorescent lamps 14 are embedded in the inner wall of the trap holes 12, and the fluorescent lamps 14 are controlled by a photovoltaic power supply and a light control switch. The bottom of the connecting ring 16 has an insertion hole, and the lure rod 17 is fixed to the insertion hole by a locking block 171 connected at the upper end. The bottom of the lure rod 17 extends into the collection tank 19.

[0029] As a preferred implementation, by setting the vent 11, the wind impact area of ​​the trap body 1 can be reduced in windy weather, thereby reducing the swaying caused by wind.

[0030] Specifically, each plastic barb 13 is designed as an isosceles triangle, with the upper end of the plastic barb 13 bonded and fixed to the periphery of the outer hole of the trapping hole 12, and the inner tip of the plastic barb 13 suspended in the air facing the center of the trapping hole 12.

[0031] As a preferred implementation, by setting plastic barbs 13, the enclosed hollow cone structure allows pests to crawl in while preventing them from crawling out.

[0032] Specifically, the socket includes a transverse hole and a longitudinal hole, with the longitudinal hole penetrating through the connecting ring 16. The longitudinal hole is opened on the end face of the inner ring wall of the connecting ring 16, and the transverse hole and the longitudinal hole are connected in a cross shape.

[0033] During installation, the locking block 171 passes upward through the longitudinal hole and then rotates ninety degrees, so that the locking block 171 moves downward and engages in the transverse hole, thus achieving the effect of easy disassembly and assembly of the decoy rod 17.

[0034] In use, the trap body is fixed in the forest using the clamps and locking blocks included in the fixing components. During the fixing process, the height of both ends of the trap body can be adjusted using the telescopic rod and sleeve. The fixed trap body can increase stability in windy weather. The wind holes reduce wind resistance and further increase the stability of the installed trap body, thus preventing damage caused by swaying. The fluorescent light and lure stick inside the trap hole lure pests into the trap hole. The pests then pass through the plastic barbs into the inner cavity and then enter the collection container along with the lure stick. When the pests come into contact with the insecticide in the collection container, they can be killed in a short time. At the same time, pests that do not enter the collection container are blocked by the plastic barbs and cannot fly out of the trap hole, thus improving the effectiveness of the trap.

[0035] The biodegradable pine wilt nematode vector insect trap of this utility model can effectively solve the problems mentioned in the background technology. It achieves a stable fixation effect on the trap and enhances the prevention and killing effect on pests based on the existing biodegradable pine wilt nematode vector insect trap technology.
