摘要
棉蚜Aphis gossypii Glover是棉花生产中最严重的害虫之一。长期以来防治棉蚜主要依赖于化学杀虫剂,其中新烟碱类杀虫剂扮演着十分重要的角色,但由于其长期、大量的使用,棉蚜已对该类杀虫剂产生了较高水平的抗性,严重影响了对棉蚜的防治效果。抗性机制研究表明,棉蚜对新烟碱类杀虫剂产生抗性的机制主要涉及解毒代谢能力增强和靶标敏感性下降。细胞色素P450、羧酸酯酶、谷胱甘肽S-转移酶、UDP-葡糖基转移酶等解毒酶基因过量表达介导的解毒代谢增强和烟碱型乙酰胆碱受体β1亚基突变引起的靶标敏感性下降是棉蚜对新烟碱类杀虫剂产生抗性的关键。针对我国棉蚜对新烟碱类杀虫剂抗性问题突出的现状,为更好地利用该类药剂防治棉蚜,亟需根据棉蚜抗性机制制定合理的抗性治理策略。本文将从棉蚜对新烟碱类杀虫剂的抗性现状、抗性机制以及抗性治理策略等方面进行综述,以期为抗性棉蚜的科学治理提供参考。
Aphis gossypii Glover is one of the most serious insect pests in cotton production.The control of A.gossypii has been largely dependent on the application of chemical insecticides,among which neonicotinoid insecticides has played a very important role.However,due to the long-term,large-scale,and unreasonable use,A.gossypii has evolved high level of resistance to neonicotinoid insecticides,which has seriously reduced the control efficacy of neonicotinoids to cotton aphids.Previous studies of resistance mechanisms demonstrated that the enhanced detoxification mediated by the overexpression of detoxify enzyme genes,such as cytochrome P450,carboxylesterases,glutathione S-transferases,and UDP-glycosyltransferases,and the decreased target sensitivity caused by the mutation of nicotinic acetylcholine receptorsβ1 subunit were the main resistance mechanisms of A.gossypii against neonicotinoid insecticides.In view of the prominent resistance status of A.gossypii to neonicotinoid insecticides,to effectively use of neonicotinoid insecticides for controlling A.gossypii in the fields,more reasonable resistance management strategies need to be developed according to the resistance mechanisms.In the present review,the current status of resistance and resistance mechanism of A.gossypii to neonicotinoid insecticides as well as the strategies for insecticide resistance management in A.gossypii were reviewed.
