Abstract:

RNA interference(RNAi)is a physiological phenomenon of post-transcriptional degradation of endogenous genes in organism,and it is widely present in organisms. RNAi is mainly induced by short/small RNA to hinder the translation or transcription of the target gene,and which cause the target messenger RNA to be silence. RNAi has the advantages of high efficiency and specificity,thus it is widely used in insect gene function research and has shown great potential for development of novel pest management strategies. This review mainly expounds the silencing mechanism of RNAi,several ways of transferring double-stranded RNA into insects,and the latest research progress of RNAi technology in insects of different orders. Finally,the paper briefly summarizes the shortcomings of RNAi technology,and prospects the application of RNAi technology in pest control,with a view to providing theoretical support for the widespread application of this technology in agricultural pest control.

Key words: RNA interference, insect, transfer mechanism, pest control
