Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of forestry, especially to a trapping device for preventing and treating insect oviposition. BACKGROUND

[0002] At present, the prevention and treatment of forestry pests mainly relies on chemical agents, which is widely used due to its quick effect in a short time. However, with the abuse of chemical agents, many ecological environmental problems have been caused, and the pesticide resistance of pests has also increased with the use of chemical agents, greatly reducing the persistence period of chemical agent control. Therefore, physical control has important significance for reducing the occurrence of pests, ensuring food safety, and delaying the development of pest resistance.

[0003] Physical control often uses insect-sticking color plates, insecticidal lamps, and new traps to attract and control pests, mainly including: (1) light attraction, i.e., using frequency vibration lamps, black light lamps, and fluorescent lamps to kill insects; (2) sexual attraction, i.e., using artificially synthesized or insect-extracted sex pheromones to attract opposite-sex insects; (3) chemical attraction, i.e., using chemical attractants such as sugar vinegar and methyl eugenol to attract insects; (4) plant attraction, i.e., cultivating preferred plants to attract insects and reduce the damage rate of pests on crops; (5) yellow plate attraction, i.e., using the color preference of insects to kill insects with yellow sticky plates.

[0004] In Chinese Patent Application CN118844404A, a natural enemy-friendly pest trapping light source and its application are disclosed. The utility model discloses a 365nm+385nm+605nm combined wavelength of the light source, which has a good attraction effect on pests, especially on the grassland armyworm. Moreover, the light source with the combined wavelength is friendly to other insects or natural enemy insects except pests, mainly showing weak attraction to other insects except pests. The combination of the light source with the combined wavelength, a wind suction device, a fold line-shaped insect collecting channel, and a natural enemy escape port can effectively reduce the escape of pests, further protecting natural enemy insects or neutral insects.

[0005] For example, Chinese patent CN110024762B discloses an insect trap for hanging, which is characterized in that: the insect trap comprises a first cavity for containing insecticidal liquid and a box body for containing attractant, further comprises a second cavity for containing the box body, the second cavity has an opening for the box body to put in or take out, and the second cavity is located in the first cavity; the opening of the second cavity comprises a first opening located in the first cavity and a second opening located at the bottom of the first cavity; the first cavity has an opening for the insecticidal liquid to be injected, and the opening of the first cavity is in the same direction as the first opening; a partition plate is arranged in the first cavity to surround the second cavity, one end of the partition plate is a connecting end connected with the first cavity, the other end of the partition plate is a free end, and the free end of the partition plate surrounds the first opening; the connecting end of the partition plate is located at the second opening, and the second opening and the connecting end of the partition plate have the same size and shape; the free end of the partition plate is located in a plane parallel to the bottom of the first cavity; the center line of the first cavity and the center line of the second cavity are located on the same straight line; the first cavity is provided with a drain hole on the side wall, and the first opening is located above the drain hole; the insect trap further comprises a hanging piece and a connecting rod, the hanging piece suspends a sexual attractant or a sticky insect board, and the sexual attractant or the sticky insect board is located above the liquid level of the insecticidal liquid in the first cavity; the insect trap further comprises a cover for covering the first opening, the cover is provided with a through hole, the cover has a limiting piece for limiting the relative position of the cover and the second cavity, the limiting piece is located on the back of the cover, and the limiting piece comprises a first baffle and a second baffle, when the cover covers the first opening, the first baffle is located outside the first opening, and the second baffle is located inside the first opening.

[0006] The main control objects in the above-mentioned methods are adult insects, and the cost is relatively high. However, oviposition is the first step of pest damage, and the hatched larvae are the main damage agents. Attracting insects to oviposit on non-plant devices can greatly reduce the number of insect eggs on protected plants and effectively reduce pest damage. Practical new type content
