The Colorado potato beetle, Say, is a potato pest that can cause important economic losses to the potato industry worldwide. Diverse strategies have been deployed to target this insect such as biological control, crop rotation, and a variety of insecticides. Regarding the latter, this pest has demonstrated impressive abilities to develop resistance against the compounds used to regulate its spread. Substantial work has been conducted to better characterize the molecular signatures underlying this resistance, with the overarching objective of leveraging this information for the development of novel approaches, including RNAi-based techniques, to limit the damage associated with this insect. This review first describes the various strategies utilized to control and highlights different examples of reported cases of resistances against insecticides for this insect. The molecular leads identified as potential players modulating insecticide resistance as well as the growing interest towards the use of RNAi aimed at these leads as part of novel means to control the impact of are described subsequently. Finally, select advantages and limitations of RNAi are addressed to better assess the potential of this technology in the broader context of insecticide resistance for pest management.
科罗拉多马铃薯甲虫(Say)是一种马铃薯害虫,会给全球马铃薯产业造成重大经济损失。人们已采用多种策略来对付这种害虫,如生物防治、轮作以及多种杀虫剂。就后者而言,这种害虫已展现出对用于控制其传播的化合物产生抗性的惊人能力。为更好地表征这种抗性背后的分子特征,人们开展了大量工作,总体目标是利用这些信息开发新方法,包括基于RNA干扰的技术,以减少与这种害虫相关的损害。本综述首先描述了用于控制的各种策略,并重点介绍了该害虫对杀虫剂产生抗性的不同报道案例。随后描述了被确定为调节杀虫剂抗性的潜在分子线索,以及对将针对这些线索的RNA干扰作为控制该害虫影响的新手段的兴趣日益浓厚。最后,阐述了RNA干扰的一些优点和局限性,以便在更广泛的杀虫剂抗性害虫管理背景下更好地评估这项技术的潜力。
