Abstract: Crop plants suffer severe yield losses due to the significant damages caused by aphids. RNA interference (RNAi) technology is a versatile and environmentally friendly method for pest management in crop protection. Transgenic plants expressing siRNA/dsRNA and non-transformative methods such as spraying, microinjection, feeding, and a nanocarrier-delivery-mediated RNAi approach have been successfully applied for agricultural insect pest management. In this review, we summarize the application of host-induced gene silencing (HIGS)-mediated RNAi, spray-induced gene silencing (SIGS)-mediated RNAi, and other delivery-method-mediated RNAi methods for aphid control. We further discuss the challenges in RNAi application and propose potential solutions to enhance RNAi efficiency.
