AI Technical Summary

Technical Problem

In existing technologies, single chemical agents lead to increased resistance of stored insects, and the control effect gradually declines year by year. Biological agents have a slow onset of action and a limited target range, making it difficult to achieve long-term, multi-faceted control of grain storage pests.

Method used

A compound preparation of chemical reagent 2-phenylethanol with Bacillus amyloliquefaciens and Bacillus brevis is used. 2-phenylethanol misleads flying insects to avoid oviposition sites, while Bacillus amyloliquefaciens and Bacillus brevis colonize the surface of grains and produce inhibitory substances, interfering with the development of insect eggs and forming a biological protective layer.

Benefits of technology

It achieves rapid repellency of flying insects, significantly reduces egg laying, effectively blocks pest reproduction for a long time, and does not affect grain quality. It is also simple to operate and easy to integrate.

Abstract

This invention provides a biological compound preparation for repelling insects or reducing the oviposition of flying insects, its preparation method, and its application. The biological compound preparation for repelling insects or reducing the oviposition of flying insects includes a chemical reagent and a biological agent; wherein the chemical reagent includes 2-phenylethanol, and the biological agent includes *Bacillus amyloliquefaciens* and *Bacillus brevis*; the preservation number of *Bacillus amyloliquefaciens* is CGMCC No. 35162, and the preservation number of *Bacillus brevis* is CGMCC No. 35161. The core advantage of this invention lies in the synergistic effect of 2-phenylethanol (chemical reagent) with *Bacillus amyloliquefaciens* (CGMCC No. 35162) and *Bacillus brevis* (CGMCC No. 35161) (biological agent). Through complementary and mutually reinforcing mechanisms, the two significantly enhance the control effect.
