Advance of RNA interference technique in Hemipteran insects

RNA interference (RNAi) suppressed the expression of the target genes by post transcriptional regulation and the double-stranded RNA (dsRNA) mediated gene silencing has been a conserved mechanism in many eukaryotes, which prompted RNAi to become a valuable tool for unveiling the gene function in many model insects. Recent research attested that RNAi technique can be also effective in downregulation target genes in Hemipteran insects. In this review, we collected the researches of utilizing RNAi technique in gene functional analysis in Hemipteran insects, highlighted the methods of dsRNA/siRNA uptake by insects and discussed the knock-down efficiency of these techniques. Although the RNA interference technique has drawbacks and obscure points, our primary goal of this review is try to exploit it for further discovering gene functions and pest control tactic in the Hemipteran insects.
