Description

Technical Field

[0001] This utility model relates to the field of pest control technology, specifically to a trap suitable for larch caterpillars. Background Technology

[0002] Larch caterpillars are a major pest in forestry. Traps, commonly used for monitoring and controlling this pest, typically consist of a funnel to guide the caterpillars in and a collection bottle detachably connected to the funnel. However, existing traps lack a structure at the funnel opening that effectively prevents caterpillars from escaping while ensuring they fall smoothly into the collection bottle. Furthermore, when used with the funnel, the collection bottle's opening must remain open to receive caterpillars falling from the funnel. When the collection bottle needs to be removed from the funnel for counting, processing, or replacement, its opening is completely open, allowing captured caterpillars to easily escape. This not only reduces the trap's efficiency but also affects the accuracy of data monitoring larch caterpillar populations, failing to meet the needs of practical forestry pest control. Therefore, a suitable trap for larch caterpillars is urgently needed. Utility Model Content

Detailed Implementation

[0016] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. The preferred embodiments described are only examples. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0017] like Figures 1-4 As shown, the specific embodiment adopts the following technical solution: it includes an insect collection bottle 1 and a funnel 2. The insect collection bottle 1 is fitted under the funnel 2. An observation port is provided on the left side wall of the insect collection bottle 1. An observation window 18 is provided inside the observation port. The insect population density can be quickly estimated without opening the insect collection bottle 1 by using the observation window 18. It also includes: Support rod 3, there are several support rods 3, which are distributed at the upper part of the funnel 2 with equal rounded corners. The upper ends of the several support rods 3 are fixedly provided with rain cover 4, and the upper part of the rain cover 4 is fixedly provided with hook 5. The insect collection bottle 1 is provided with a disassembly and closure mechanism 12. A vertical rod 6 is fixedly installed inside the rain cover 4. A pheromone emitter 7 is fixedly installed at the lower end of the vertical rod 6. A reinforcing rod 17 is fixedly installed on the support rod 3, and one end of the reinforcing rod 17 is fixedly connected to the vertical rod 6. The reinforcing rod 17 can be used to connect the vertical rod 6 and the support rod 3, thereby effectively improving the structural strength of the trap. A mobile power supply 8 is fixedly installed inside the rain cover 4, and the mobile power supply 8 is electrically connected to the pheromone emitter 7. A crossbar 9 is fixedly installed at the bottom opening of the funnel 2. A first baffle 10 is rotatably connected to both the left and right sides of the crossbar 9, and the first baffle 10 is set to abut against the bottom of the funnel 2. A metal spring 11 is fixedly installed at the bottom of the crossbar 9, and the metal spring 11 is set to abut against the two first baffles 10. A sticker 15 is provided on the upper part of the first baffle 10, and a fluorescent coating 16 is provided on the upper part of the sticker 15. By utilizing the phototaxis of the larch caterpillar, the fluorescent coating 16 on the sticker 15 can guide the larch caterpillar to fly downward and enter the insect collection bottle 1. The disassembly and closure mechanism 12 includes: Rotating rod 12-1, there are two rotating rods 12-1, both of which are rotatably installed inside the insect collecting bottle 1 through bearings. The second baffle 12-2 is movably abutted on both the left and right sides of the insect collecting bottle 1. The rotating rod 12-1 is fixedly inserted into the second baffle 12-2. The fixing block 12-3 is fixedly installed on the front side of the insect collecting bottle 1. The front end of the rotating rod 12-1 passes through the insect collecting bottle 1 and is inserted into the fixing block 12-3 through the bearing. Gears 12-4 are fixedly sleeved on both rotating rods 12-1. The two gears 12-4 are meshed and located inside the fixing block 12-3. Two torsion springs 12-5 are movably sleeved on two rotating rods 12-1 respectively. The two ends of the torsion springs 12-5 are fixedly connected to the gear 12-4 and the inner wall of the fixing block 12-3 respectively. A flipping rod 12-6 is rotatably provided on the front side of the fixing block 12-3 through a rotating shaft. The flipping rod 12-6 is fixedly connected to the rotating rod 12-1 on the right side. A fixing plate 12-7 is fixedly installed on the front side of the funnel 2. The fixing plate 12-7 is set to abut against the flipping rod 12-6. When the insect collecting bottle 1 is removed from the funnel 2, the opening of the insect collecting bottle 1 can be self-sealed by disassembling the closing mechanism 12, so as to prevent the larch caterpillars from escaping due to the opening of the insect collecting bottle 1 not being closed in time. A limiting block 13 is fixedly installed on the flipping rod 12-6. A limiting groove 14 that cooperates with the limiting block 13 is opened on the fixing plate 12-7. The limiting block 13 can be used to realize convenient limiting between the flipping rod 12-6 and the fixing plate 12-7, so as to prevent the insect collecting bottle 1 from slipping due to insufficient friction between the insect collecting bottle 1 and the funnel 2.

[0018] When using this invention, the trap is hung at a designated position using the hook 5, and the pheromone emitted by the pheromone emitter 7 attracts the larch caterpillars into the funnel 2. The fluorescent coating 16 emits fluorescence, and the larch caterpillars fall onto the first baffle 10 due to their phototaxis. At this time, the first baffle 10 flips down due to the weight of the larch caterpillars, and the metal spring 11 bends. After the larch caterpillars on the first baffle 10 fall into the insect collection bottle 1, the metal spring 11 resets and causes the first baffle 10 to flip back to a horizontal state, closing the lower opening of the funnel 2 again to prevent the larch caterpillars in the insect collection bottle 1 from escaping during the trapping process. When it is necessary to remove the insect collecting bottle 1 from the funnel 2, the flipping rod 12-6 can be flipped to the right at a certain angle so that the limiting block 13 disengages from the limiting groove 14. Then, the insect collecting bottle 1 can be pulled down to disengage from the funnel 2, and the flipping rod 12-6 can be released. At this time, the torsion spring 12-5 drives the gear 12-4 connected to it to rotate. By using the meshing of the two gears 12-4, the rotating rods 12-1 on both sides can be rotated synchronously in opposite directions. The rotating rods 12-1 drive the second baffle 12-2 to flip to a horizontal state, thereby sealing the insect collecting bottle 1 and preventing the pine caterpillars from escaping during the disassembly of the insect collecting bottle 1.

[0019] Compared with the prior art, the beneficial effects of this utility model are: The pheromone emitter 7 actively attracts larch caterpillars by emitting pheromones. Combined with the fluorescent coating 16 on the sticker 15 on the upper part of the first baffle 10, the insects are guided to fly downwards by phototaxis. The first baffle 10 can also flip with the weight of the insects to allow them to fall in. The metal spring 11 drives the funnel 2 to reset and close the opening, forming a continuous mechanism of attraction-guidance-escape prevention, which greatly improves the trapping efficiency. When the insect collecting bottle 1 is disassembled, the second baffle 12-2 is automatically flipped by the torsion spring 12-5, gear 12-4 and rotating rod 12-1 to achieve automatic sealing of the insect collecting bottle 1, so as to prevent larch caterpillars from escaping through the opening of the insect collecting bottle 1 during this process. By utilizing the cooperation between the limiting block 13 and the limiting groove 14, the insect collecting bottle 1 can be prevented from slipping due to insufficient friction with the funnel 2, thus ensuring the installation stability of the insect collecting bottle 1. The left side wall of the insect collection bottle 1 is equipped with an observation port with an observation window 18, which allows for quick estimation of the density of larch caterpillars without opening the insect collection bottle 1. This avoids the problem of pests escaping due to frequent opening of the insect collection bottle 1, and also eliminates the tedious steps of disassembling and opening the insect collection bottle 1, significantly simplifying the insect population monitoring operation process and improving monitoring efficiency.

[0020] For those skilled in the art, modifications can be made to the technical solutions described in the foregoing embodiments, and equivalent substitutions can be made to some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
