RNAi技术在烟粉虱基因功能和防控研究中的应用

Application of RNA interference technology in the gene function and control of Bemisia tabaci

烟粉虱(Bemisia tabaci)是一种世界性蔬菜害虫,可传播多种植物病毒,影响植物生长发育,导致蔬菜产量下降。烟粉虱的防治以化学防治为主,但过度使用杀虫剂导致烟粉虱的抗药性不断增强,绿色防控的需求日益增加。RNA干扰(RNA interference,RNAi)是一项特异性沉默靶标基因技术,广泛应用于昆虫的基因功能研究和绿色防控。通过介绍RNAi作用原理和RNAi在烟粉虱的基因功能,总结了RNAi在烟粉虱的防控应用和RNA农药的应用现状,为烟粉虱的新靶点研究和开发RNA农药进行烟粉虱防控应用提供参考。

Bemisia tabaci is a worldwide vegetable pest that can transmit a variety of plant viruses,affecting plant growth and development,and leading to the decrease of vegetable production.The control of whitefly is dominated by chemical control.However,the excessive use of insecticides has led to the increasing resistance of whitefly,and the demand for green control is increasing.RNA interference(RNAi)is a technology that specifically silences target genes and is widely used in gene function research and green control in insects.This paper introduces the principle of RNAi and the research on the gene function of RNAi in whitefly,summarizes the application of RNAi in the prevention and control of whitefly and the application status of RNA pesticides.It provides a reference for the research on new targets of whitefly and the RNA pesticide development for the prevention and control of whitefly.
