Cage for catching and killing harmful imagoes

Abstract

The invention discloses a cage for catching and killing harmful imagoes. The cage comprises a cover plate; the cover plate is fixedly sleeved with a net cage cover; the net cage cover is of a circular net structure with openings in the upper end and the lower end; the lower end of the net cage cover is in through connection with the upper end of a funnel; a pest storage device is arranged at the lower end of the funnel; net holes are formed in the two sides of the net cage cover; a conical net cover is fixedly connected to the net holes; imagoes are attracted into the net cover through an induction box, so that the imagoes can be trapped in the net cover, the imagoes flap steel wire ropes when flapping wings in the net cover, the wings of the imagoes are damaged and lose the flying ability, the imagoes are caught and killed, and no imagoes exist, and incubation of larvae through oviposition is avoided; and the cage for catching and killing the harmful imagoes is simple in structure, reasonable in layout, capable of being placed in a field farmland for a long time, convenient to use and capable of replacing a pesticide deinsectization method on a large scale.

Description

technical field [0001] The invention relates to the technical field of pest control, in particular to a cage for killing harmful adults. Background technique [0002] In the process of tobacco growth, there are lepidopteran pest larvae such as cutworms, tobacco budworms, and Spodoptera litura successively, causing great losses. Tobacco farmers generally use pesticides to prevent and control, but this not only increases the pesticide residues on tobacco leaves, but also destroys ecosystem. [0003] At present, there are also trap cages designed for the good absorption of sweet and sour liquid by adult Lepidoptera pests of tobacco. When the vinegar smells, they will try their best to get into the cage to inhale. Through the designed conical net cover, the adults can only fly in and not fly out, so as to achieve the purpose of killing the adults. Without the adults, they cannot lay eggs and hatch larvae. The method has a good hunting ability, but on the one hand, because the ...

[0003] At present, there are also trap cages designed for the good absorption of sweet and sour liquid by adult Lepidoptera pests of tobacco. When the vinegar smells, they will try their best to get into the cage to inhale. Through the designed conical net cover, the adults can only fly in and not fly out, so as to achieve the purpose of killing the adults. Without the adults, they cannot lay eggs and hatch larvae. The method has a good hunting ability, but on the one hand, because the sweet and sour liquid evaporates quickly during use, especially in summer when the temperature is high, it needs to be manually added after a period of use, and the cages are generally set far away from the tobacco farmers. There are a lot of cages in the field where they live, so the operation of adding sweet and sour liquid is very time-consuming and laborious for tobacco farmers. On the other hand, dead bodies in the cages will also accumulate at the bottom, and tobacco farmers also need to do it manually. clean up, time consuming
