RNA interference (RNAi) is an homology‐dependent gene silencing mechanism that is a feasible and sustainable avenue for the management of hemipteran pests. Commercial implementation of RNAi‐based control strategies is impeded by limited knowledge about the mechanism of double‐stranded RNA (dsRNA) uptake, the function of core RNAi genes and systemic RNAi mechanisms in hemipteran insects. This review briefly summarizes recent progress in RNAi‐based studies aimed to reduce insect populations, viral transmission and insecticide resistance focusing on hemipteran pests. This review explores RNAi‐mediated management of hemipteran insects and offers potential solutions, including in silico approaches coupled with laboratory‐based toxicity assays to circumvent potential off‐target effects against beneficial organisms. We further explore ways to mitigate degradation of dsRNA in the environment and the insect such as stacking and formulation of dsRNA effectors. Finally, we conclude by considering nontransformative RNAi approaches, concatomerization of RNAi sequences and pyramiding RNAi with active constituents to reduce dsRNA production and application cost, and to improve broad‐spectrum hemipteran pest control. © 2020 Society of Chemical Industry

基于RNAi的半足动物控制的当前方案

RNA干扰(RNAi)是一种依赖同源性的基因沉默机制,是处理半足动物害虫的可行且可持续的途径。关于双链RNA(dsRNA)摄取的机制,半RNA昆虫中核心RNAi基因的功能和系统性RNAi机制的有限知识,阻碍了基于RNAi的控制策略的商业实施。这篇综述简要总结了基于RNAi的研究的最新进展,这些研究旨在减少针对半足动物害虫的昆虫种群,病毒传播和抗药性。这篇综述探讨了RNAi介导的半足类昆虫的管理,并提供了包括计算机技术在内的潜在解决方案方法与基于实验室的毒性测定相结合,规避了对有益生物的潜在脱靶效应。我们进一步探索减轻环境和昆虫中dsRNA降解的方法,例如dsRNA效应子的堆叠和配制。最后,我们通过考虑非转化性RNAi方法,RNAi序列的胶结化和将RNAi与活性成分金字塔化来结束,以降低dsRNA的生产和应用成本,并改善广谱半足类害虫的防治。©2020化学工业协会
