背景：类烟碱杀虫剂是欧洲核果生产商使用的害虫管理策略的关键组成部分。新烟碱类化合物是目前防治桃-马铃薯蚜虫（Myzus persicae）的最重要的工具之一。对类烟碱的过度依赖导致了个体蚜虫通过代谢和靶位点抗性机制的组合而产生抗性。2010年，先正达开展了一项耐药性监测项目，以确定M.结果：抗性监测结果表明，烟粉虱对新烟碱类化合物的抗性在烟粉虱种群中较为普遍。从法国的Educo-Alpesillon、普罗旺斯-阿尔佩斯-科特达祖尔和罗纳-阿尔佩斯地区的桃园收集的桃蚜中，抗性可以与靶位点突变（R81 T）的频率相关。在其杂合形式的R81 T突变也存在于西班牙人口，并与烟碱类药物resistance.CONCLUSION：烟碱类药物在法国南部的抗性和抗性发展的潜力在北方西班牙的广泛性质突出需要一个协调的管理策略，采用不同的行动模式，以减少选择压力与烟碱类药物杀虫剂。(C)2011年化学工业协会
BACKGROUND: The neonicotinoid class of insecticides is a key component of pest management strategies used by stone fruit producers in Europe. Neonicotinoids are currently one of the most important tools for control of the peach-potato aphid (Myzus persicae). Overreliance on neonicotinoids has led to the development of resistance through a combination of metabolic and target-site resistance mechanisms in individual aphids. A resistance monitoring project was conducted by Syngenta in 2010 to determine the resistance status of M. persicae populations collected from France and Spain, and to determine the frequency of the target-site mutation in those populations.RESULTS: Resistance monitoring suggests that resistance toneonicotinoids is relatively widespread in populations of M. persicae collected from peach orchards in the Languedoc-Roussillon, Provence-Alpes-Cote d'Azur and Rhone-Alpes regions of France, and resistance can be associated with the frequency of the target-site mutation ( R81T). The R81T mutation in its heterozygous form is also present in Spanish populations and is associated with neonicotinoid resistance.CONCLUSION: The widespread nature of neonicotinoid resistance in southern France and the potential for resistance development in northern Spain highlight the need for a coordinated management strategy employing insecticides with different modes of action to reduce the selection pressure with neonicotinoids.
