Abstract:

xogenous or endogenous double-stranded RNA (dsRNA) can be used to apply RNA interference (RNAi) to targeted insect genes. There has recently been progress in the utilization of RNAi technology to control agricultural pests. The high cost of dsRNA synthesis is the main obstacle to the application of RNAi in the field. We constructed a cheap and efficient dsRNA production method using the L4440 and HT115 (DE3) bacterial strains that can significantly reduce the cost of dsRNA production compared to commercial kits. Our method has the potential for large scale assays of insect gene function and for the field application of RNAi reagents, which may promote the practice and development of RNAi-based pest control.
