摘要
RNA interference (RNAi) suppresses the expression of target genes by post- transcriptional regulation. Because double-stranded RNA (dsRNA) mediated gene silenc- ing is a conserved mechanism in many eukaryotes, RNAi has become a valuable tool for unveiling gene function in many model insects. Recent research has also shown that RNAi can also be effective in the downregulation of target genes in Hemiptera. In this review, we discuss the use of the RNAi technique in gene functional analysis in hemipterans, highlighting the methods of dsRNA uptake by these insects and discuss the knock-down efficiency of these techniques. Although the RNAi technique has disadvantages, our pri- mary goal here is to determine whether it can be exploited further in the discovery of new ~ene functions, and as a oest control strategy, in some important HemiDteran oests.
