调控小菜蛾抵御蝉拟青霉侵染的基因、制备方法及其应用
By regulating the PGRP-LB and miR308-p3 genes of the diamondback moth and using dsRNA technology to modulate the diamondback moth's immune function, the problem of slow speed and unstable effect of fungal insecticides in controlling the diamondback moth was solved, achieving a highly efficient biological control effect.

AI Technical Summary
Existing fungal insecticides are slow to kill and have unstable control effects when controlling diamondback moth. They are also easily affected by the environment. The immune mechanisms of insects against pathogenic fungal infection are not fully understood, resulting in unsatisfactory control effects.
By regulating the genes PGRP-LB and miR308-p3 in the diamondback moth, and using dsRNA to interfere with PGRP-LB expression or mimic/inhibit miR308-p3 expression, the immune function of the diamondback moth can be regulated, thereby enhancing its resistance to Paecilomyces cicadae.
It significantly improved the control effect of diamondback moth on Paecilomyces ciliata, reduced the survival rate of pests, reduced the development of drug resistance, and the preparation method can be mass-produced and has strong environmental adaptability.
