Attractant for Anomala corpulenta

Abstract

The invention belongs to the technical field of insect prevention and control, and discloses an attractant for Anomala corpulenta. The attractant is of a core-shell structure, which comprises a outer shell layer and an inner core layer; the inner core layer is divided into two parts, and the two parts are separated, wherein the first part comprises methyleugenol, beta-ionol, vanillyl alcohol, brown sugar, geranene, ethyl alcohol, andrographolide, nerol, benzyl phenylacetate, cis-3-hexenepentanol and 4-methylethylenone-beta-D galactoside, and the second part is beta-galactosidase; and the outer shell layer isgelatin. The attractant disclosed by the invention has the advantages that the attractant has very strong capability of trapping the Anomala corpulenta, is good in stability and high in specificity, and does not cause resistance to the Anomala corpulenta.

Description

technical field [0001] The invention relates to the technical field of insect control, in particular to an attractant for the aeruginosa beetle. Background technique [0002] Subterranean pests are major pests recognized both at home and abroad that are difficult to predict and control. They mainly damage crop seedlings, roots and tubers. Grubs are the collective name for the larvae of the Coleoptera Scaraboidoidea, the largest group of underground pests, and the species that cause the greatest loss and the most harm. Both larvae and adults of the scarab beetle can cause serious damage. The larvae mainly feed on the underground rhizomes and pods of various crops, causing the crops to wither and die. Bald stalks seriously affect the quality and yield of agricultural products. According to survey statistics, 86% of damage to underground parts of plants is caused by scarab beetle larvae. At present, chemical agents are the main means for preventing and controlling scarab beet...

AI Technical Summary

Problems solved by technology

[0004] In the past, we mainly relied on long-lasting chemical agents for prevention and control, but most of the insecticides used in production are pesticides with short residual effects. It is difficult to control grub damage in autumn crops by using traditional methods such as soil treatment and chemical seed dressing. achieve the desired effect

With the restriction and prohibition of some highly toxic and high residue pesticides (organophosphorus, carbamate, etc.), the control effect of many pesticides on grubs is not ideal

At the same time, the soil will also be permanently or semi-permanently polluted to varying degrees, which in turn will cause quality and safety issues for agricultural products.
