AI Technical Summary
Technical Problem
The resistance of diamondback moth to chemical insecticides has increased rapidly, and existing prevention and control methods are difficult to effectively solve this problem.
Method used
The Enterobacter hormaechei A3 strain of Enterobacter hormaechei A3 was isolated and screened from the intestine of the diamondback moth. Through feeding tests and in vitro degradation tests, it was verified to improve the resistance and ability of the diamondback moth to degrade pesticides.
Benefits of technology
Enterobacter hormaechei A3 strain significantly increased the resistance of Riceworm to chlorobacteria and Fluobacteria chlorobacteria and effectively degrade these pesticides in vitro, reducing pesticide residues.

Abstract
The invention discloses an Enterobacter holmesii A3 strain and its application, and the strain is preserved in the Guangdong Provincial Microbial Culture Collection Center, and the biological preservation number is: GDMCC NO: 64603. The Enterobacter holmesii A3 strain of the invention can improve the production of resistance of diamondback moth, and the strain can survive in a culture medium containing only bromofenac or chlorfenapyr as the only nutrient source, and can degrade the pesticide in vitro; the Enterobacter holmesii A3 strain of the invention provides a basis for the study of the resistance mechanism of diamondback moth, and at the same time, because it has the application in pesticide degradation, it provides a basis for the application of biological control.
