Lure and kill device for farmland lepidopteran pest corn borer larvae attractant

Abstract

A device for attracting and killing corn borer larvae, a lepidopteran pest in farmland, belongs to the technical field of plant protection and consists of a trap ring (1), a terminal plug (14), a bayonet (15) and a fixed tie (16). It is characterized in that: the booby trap (1) is in the shape of a ring, and there is a gap called bayonet (15), and the two sides of the bayonet are end plugs (14), and each end plug (14) is outside A fixed tie (16) is all arranged, and after the corn stalk is blocked, the fixed tie (16) can be fastened in a knotted mode, so that the trap ring (1) can be firmly fixed on the corn stalk Above; the trapping ring (1) is plastic, rubbery or fibrous, including the attractant storage bag (2), the return insect collar (3), the killing liquid (4), the trapping ring cavity (5), the insect inlet ( 6), blocking escape (7) and plant cavity (13). The device is simple in manufacture, strong in operability, low in cost and obvious in effect.

Description

technical field [0001] The invention relates to a device for attracting and killing corn borer larvae, a lepidopteran pest in farmland, and belongs to the technical field of plant protection. Background technique [0002] Corn borer, also known as corn borer, belongs to Lepidoptera, Boreridae. There are two types of corn borer in my country, the Asian corn borer and the European corn borer. They mainly damage corn, sorghum, millet, etc., and can also damage cotton, sugarcane, Hemp, sunflower, rice, sugar beet, beans and other crops are worldwide pests. Corn borer adults are yellowish brown, the male moth is 13-14mm long, and the wingspan is 22-28mm. The body length of the female moth is about 14-15 mm, the wingspan is 28-34 mm, the body is bright yellow, and each line is reddish brown. Eggs are flat and elliptical, about 1 mm long and 0.8 mm wide. Several to dozens of eggs form egg masses, arranged in the shape of fish scales, initially milky white, gradually changing to ye...

AI Technical Summary

Problems solved by technology

Since the position of corn borer larvae on corn plants changes over time, especially in the interior of the stalk, general insecticides and other control measures have no obvious killing effect on them, so how to kill corn borer efficiently Larvae have become a major problem that needs to be solved urgently. Therefore, the attractant and killing device for corn borer larvae, a lepidopteran pest in farmland, uses the different activity positions and feeding habits of corn borer larvae on corn plants in different periods. Borer larvae are lured into it and killed with killing liquid, so as to achieve the purpose of efficiently killing corn borer larvae. It is necessary to invent a lure and kill device for farmland lepidopteran pest corn borer larvae.
