Insect trapper

Abstract

The invention relates to an insect trapper. A supporting rod insertion hole is formed in the center of the bottom of a bottom cylinder, a central positioning stand column is fixedly mounted at the position, which corresponds to the supporting rod insertion hole, of a bottom plate of the bottom cylinder; the central positioning stand column is of a cylindrical hollow structure; the bottom of the central positioning stand column communicates with the supporting rod insertion hole; a cover body is movably mounted on the top of the central positioning stand column; a supporting ring is fixedly mounted on the inner wall of the bottom cylinder; a leaking hole disc sleeves the outer side of the central positioning stand column and positioned above the supporting ring; and an attractant carrying sponge ring block sleeves the outer side of the central positioning stand column and positioned above the leaking hole disc. The trapping and killing effect of an attractant can be improved, and an insecticidal effect of the attractant can be maintained for a long time. Moreover, the insect trapper is simple in structural design and low in integral design cost, can be popularized and used, and plays a positive and important role in green prevention and control of tobacco production, accurate pesticide application and reduction of pesticide consumption at present in China.

Description

technical field [0001] The invention relates to the field of tobacco planting, in particular to an insect trap. Background technique [0002] In the process of tobacco production, it is extremely vulnerable to pests. From the time the tobacco is transplanted to the field, it is easy to be gnawed by cutworms, resulting in the lack of seedlings and broken ridges of the tobacco plants. During the growth of tobacco, it is easy to suffer from tobacco budworms, cotton bolls Lepidopteran pests such as worms and Spodoptera litura have caused extremely serious losses to tobacco agricultural production. For the prevention and control of this kind of pests, in the adult stage, the method of trapping is mainly used, including sexual temptation, lamp lure, food temptation, other physical trapping methods, etc., and chemical pesticide spraying has been mostly used in the production of larvae. method for prevention. [0003] With social progress and people's requirements for a better lif...
