背景技术背景：温室白粉虱Trialeurodes vaporariorum（Westwood），又称温室粉虱，是世界上温带地区保护地蔬菜和观赏植物的重要害虫。新烟碱类杀虫剂被广泛用于控制这一物种，虽然已经报道了耐药性，并可能成为普遍。计算了温室病菌对一系列类烟碱和吡蚜酮（一种具有不同作用模式的化合物）的抗性，并且在这些菌株中的一些菌株中发现了显著的抗性。一个很强的协会之间发现类烟碱和吡蚜酮，和交互选择实验证实了这一发现。对烟碱类杀虫剂吡虫啉和吡蚜酮的抗性表达具有年龄特异性，并且对烟碱类杀虫剂的抗性不影响推荐的施用率。vaporariorum和烟草粉虱Bemisia tabaci Gennadius，表明潜在机制可能相似。(C)2010年化学工业协会
BACKGROUND: Trialeurodes vaporariorum (Westwood), also known as the greenhouse whitefly, is a serious pest of protected vegetable and ornamental crops inmost temperate regions of the world. Neonicotinoid insecticides are used widely to control this species, although resistance has been reported and may be becoming widespread.RESULTS: Mortality rates of UK and European strains of T. vaporariorum to a range of neonicotinoids and pymetrozine, a compound with a different mode of action, were calculated, and significant resistance was found in some of those strains. A strong association was found between neonicotinoids and pymetrozine, and reciprocal selection experiments confirmed this finding. Expression of resistance to the neonicotinoid imidacloprid and pymetrozine was age specific, and resistance in nymphs did not compromise recommended application rates.CONCLUSION: This study indicates strong parallels in the phenotypic characteristics of neonicotinoid resistance in T. vaporariorum and the tobacco whitefly Bemisia tabaci Gennadius, suggesting possible parallels in the underlying mechanisms.
