Abstract Development of insecticide resistance often changes life history traits of insect pests, because metabolic detoxification of insecticides in insect bodies requires huge energetic reserves. The brown planthopper, Nilaparvata lugens (Stål), an important insect pest of rice crop in East and Southeast Asia, has developed strong resistance to imidacloprid from mid-2000s. The aim of this study was to examine the costs of life history traits and reveal changes in energy reserves with developing imidacloprid resistance. We compared the life history traits (survival time, fecundity, developmental time, and hatchability) and total lipid content between imidacloprid-resistant and imidacloprid-susceptible (control) brown planthopper strains. As compared to the control strains, adults' survival time of the resistant females was shorter, and their fecundity was lower; the other life history traits did not differ significantly between the resistant and control strains. As the results, net reproductive rates (R0) were lower in the resistant strains than in the susceptible strains. However, the amount of stored lipids was larger in resistant females than control ones. Our findings demonstrated a physiological trade-off between the development of imidacloprid resistance and the reproductive traits of brown planthopper. The imidacloprid-resistant strains are likely to store lipids for metabolic detoxification rather than consume them for reproduction.

能量储备补偿褐飞虱(半翅目:飞虱科)代谢抗性和生活史特征之间的权衡

摘要 杀虫剂抗性的发展往往会改变害虫的生活史特征,因为杀虫剂在昆虫体内的代谢解毒需要巨大的能量储备。褐飞虱 Nilaparvata lugens (Stål) 是东亚和东南亚水稻作物的重要害虫,从 2000 年代中期开始对吡虫啉产生很强的抗性。本研究的目的是检查生活史特征的成本,并揭示随着吡虫啉抗性的发展,能量储备的变化。我们比较了吡虫啉抗性和吡虫啉敏感(对照)褐飞虱品系之间的生活史特征(存活时间、繁殖力、发育时间和孵化率)和总脂质含量。与对照品系相比,抗性雌性成虫的存活时间较短,它们的繁殖力较低;其他生活史特征在抗性菌株和对照菌株之间没有显着差异。结果,抗性菌株的净繁殖率 (R0) 低于易感菌株。然而,抗性雌性中储存的脂质量大于对照雌性。我们的研究结果证明了吡虫啉抗性的发展与褐飞虱繁殖性状之间的生理平衡。吡虫啉抗性菌株可能储存脂质用于代谢解毒,而不是消耗它们用于繁殖。然而,抗性雌性体内储存的脂质量大于对照雌性。我们的研究结果证明了吡虫啉抗性的发展与褐飞虱繁殖性状之间的生理平衡。吡虫啉抗性菌株可能储存脂质用于代谢解毒,而不是消耗它们用于繁殖。然而,抗性雌性体内储存的脂质量大于对照雌性。我们的研究结果证明了吡虫啉抗性的发展与褐飞虱繁殖性状之间的生理平衡。吡虫啉抗性菌株可能储存脂质用于代谢解毒,而不是消耗它们用于繁殖。
