LsFAMeT, a juvenile hormone synthesis gene from laodelphax striatellus and its application in biological control of laodelphax striatellus

By targeting and interfering with the juvenile hormone synthesis gene LsFAMeT in the planthopper, a dsRNA interference reagent was prepared and injected into the planthopper, solving the environmental pollution and drug resistance problems caused by chemical control and achieving biological control of the planthopper.

AI Technical Summary

Technical Problem

Chemical control has led to increased resistance in planthoppers, exacerbated environmental pollution, and increased risks to the quality and safety of agricultural products. Existing technologies are insufficient to effectively control planthopper damage.

Method used

The gene LsFAMeT, which synthesizes juvenile hormone in the planthopper, was targeted and interfered with. This was achieved by preparing dsRNA interference reagents and injecting them into the planthopper, thereby interfering with its juvenile hormone synthesis and affecting its reproductive development.

Benefits of technology

It significantly inhibits oviposition by female adult planthoppers, achieving biological control of planthoppers. It is environmentally friendly and safe, providing a green control strategy.

Abstract

The application provides a Laodelphax striatellus juvenile hormone synthesis gene LsFAMeT and application thereof in biological control of the Laodelphax striatellus, and the LsFAMeT gene can be targetedly inhibited to significantly inhibit the oviposition of female adults, thereby controlling the population of the Laodelphax striatellus and reducing the damage of the Laodelphax striatellus to grain crops. The dsRNA or interference reagent is prepared by transcription of the LsFAMeT gene, and the oviposition of female adults of the Laodelphax striatellus can be effectively inhibited after the reagent is injected into the Laodelphax striatellus, so that the biological control of the Laodelphax striatellus is realized. The biological method is used for the control of the Laodelphax striatellus, and is safe and harmless to the environment and food, thereby providing a new strategy for green control of the Laodelphax striatellus.
