is a highly invasive and destructive pest distributed worldwide. Chemical insecticides remain the primary measure for their control; however, this species has already developed resistance to several insecticides. In recent years, there have been several reports of monitoring resistance in China, but continuous monitoring results are lacking and do not even span a decade. In this study, we monitored the dynamics of resistance to seven insecticides among 11 geographically distinct Chinese populations of (2010-2013; follow-up in 2023). The 11 populations were found to adapt rapidly to antibiotic insecticides (spinosad, emamectin benzoate, and avermectin), reaching high levels of insecticide resistance in several areas. Overall, a decreasing trend in resistance to organophosphorus insecticides (chlorpyrifos and trichlorfon) was observed, whereas pyrethroid (beta-cypermethrin and cyhalothrin) resistance trends were observed to both increase and decrease. The monitoring of field resistance among different populations over the duration of this study is important for improving the efficiency and sustainability of agricultural pest management, and the results provide a scientific basis for the development of more effective resistance management strategies.
是一种高度入侵性和破坏性的害虫，分布于全球。化学杀虫剂仍然是控制它们的主要措施；然而，该物种已经对几种杀虫剂产生了抗性。近年来，中国有几篇关于监测抗性的报道，但缺乏连续的监测结果，甚至没有跨越十年。在本研究中，我们监测了11个地理上不同的中国种群对七种杀虫剂的抗性动态（2010 - 2013年；2023年进行随访）。发现这11个种群对抗生素类杀虫剂（多杀菌素、甲氨基阿维菌素苯甲酸盐和阿维菌素）适应迅速，在几个地区达到了高水平的杀虫剂抗性。总体而言，观察到对有机磷杀虫剂（毒死蜱和敌百虫）的抗性呈下降趋势，而拟除虫菊酯类（高效氯氰菊酯和氯氟氰菊酯）抗性趋势则有增有减。在本研究期间对不同种群的田间抗性进行监测，对于提高农业害虫管理的效率和可持续性很重要，研究结果为制定更有效的抗性管理策略提供了科学依据。
