RNA interference (RNAi) is a highly conserved gene-silencing phenomenon, induced by 20-30 nucleotide (nt) small molecules of non-coding RNA in vivo. Three non-coding RNAs, such as small interfering RNA (siRNA), microRNA (miRNA) and PIWI-interacting RNA (piRNA), play important roles in RNAi of eukaryotes including insects. The applications of RNAi in pest control are mainly on the research of gene function, transgenic insect-resistant plants and novel nucleic acid pesticides. Before the applications, the safety risks in terms of non-target effects, target pest resistance and environmental persistence of interfering RNAs need to be strictly evaluated. In this paper, the mechanism of RNAi technology, application and safety of RNAi in agro-forestry pest control are described, which provide some theoretical basis for RNAi technology in pest control.
