摘要: 采用阈性状分析法,估算了菜缢管蚜Lipaphis erysimi(Kaltenbach)和棉铃虫Helicoverpa armigera(Hubuer)对菊马混剂及其单剂、棉铃虫对灭铃威混剂及其单剂的抗性现实遗传力,并对抗性风险和混剂延缓抗性的作用进行了评估。结果表明,菜缢管蚜和棉铃虫对混剂的现实抗性遗传力均明显小于各单剂,依次为:拟除虫菊酯>氨基甲酸酯>有机磷>混剂。混剂的使用寿命大于组成其各个单剂的使用寿命之和,抗性风险依次为:拟除虫菊脂>氨基甲酸酯>有机磷>混剂。菊马混剂对菜缢管蚜和棉铃虫,灭铃威混剂对棉铃虫均有延缓抗性发展的作用。灭铃威对棉铃虫抗性发展的延缓作用最显著。

Abstract: Realized heritabilities (h2) of resistance to F-M mixture (fenvalerate+malathion) and its components in Lipaphis erysimi (Kaltenbach) and Helicoverp aarmigera (Htibner) and to CPM mixture (cyhalothrin+parathion-methyl+methomyl)and its components in Helicoverpa armigera were estimated by threshold trait analysis.The values of h2 to mixtures in Lipaphis erysirni and Helicoverpa armigera were smaller than that of its components significantly, and the order was: pyrethroid>carbamate>organophosphorus〉mixture. The application lifetime of the two mixtures was longer than the total of its compoments's lifetimes respectively, resistance risk was: pyrethroid >carbamate>organophosphorus>mixture. Both F-M mixture and CPM mixture could delay resistance development, and CPM mixture was better in delaying resistance development in Helicoverpa armigera.
