摘要:

【目的】明确田间斜纹夜蛾(Spodoptera litura)种群对乙基多杀菌素(spinetoram)的抗性现状及抗性机制,为田间抗性预警和综合抗性治理策略的制定提供科学依据。【方法】于2023—2024年,采集我国23个斜纹夜蛾田间种群,采用浸叶法测定其对乙基多杀菌素的抗性水平;以广西南宁高抗种群(NN)和敏感品系(SS)为亲本,设置正交、反交及混交试验,通过对各处理F1代幼虫进行生物测定,明确其抗性遗传模式;测定马来酸二乙酯(diethyl maleate,DEM)、胡椒基丁醚(piperonyl butoxide,PBO)和磷酸三苯酯(triphenyl phosphate,TPP)等增效剂的增效作用,并测定抗性种群NN和敏感品系SS的羧酸酯酶(CarE)、谷胱甘肽-S-转移酶(GST)和细胞色素P450单加氧酶(P450)活性。【结果】田间抗性监测结果显示,不同地理种群斜纹夜蛾对乙基多杀菌素的抗性存在显著差异。2023年广西南宁(NN)、福建福州(FZ)种群和2024年海南三亚(SY)、云南昆明(KM)、山东潍坊(WF)、河南许昌(XC)种群均表现出高水平抗性,抗性倍数介于43.3—107.8,其中2023年广西南宁(NN)和2024年海南三亚(SY)的抗性倍数分别达106.8和107.8;2023年浙江宁波(NB)、湖北荆州(JZ)种群和2024年福建福州(FZ)、湖北荆州(JZ)、广东广州(GZ)、湖南长沙(CS)、江苏南京(NJ)、上海(SH)、广西桂林(GL)种群对乙基多杀菌素产生中等水平抗性,抗性倍数介于10.3—31.8;2023年浙江杭州(HZ)种群和2024年江西南昌(NC)、安徽合肥(HF)、北京(BJ)和浙江杭州(HZ)种群产生低水平抗性,抗性倍数介于5.0—8.9。抗性遗传方式结果表明,抗性种群NN对乙基多杀菌素的抗性为常染色体介导的不完全隐性遗传。增效剂马来酸二乙酯和磷酸三苯酯的增效比分别为1.8和1.5,对抗性种群NN的抗性具有抑制作用;NN种群中GST和CarE活性分别为敏感品系SS的4.1和3.5倍。【结论】我国多个地区的斜纹夜蛾种群已对乙基多杀菌素产生抗性,GST和CarE活性增强是其抗性形成的重要因素。

Abstract:

【Objective】This study aims to clarify the current resistance status and underlying mechanisms of field populations of Spodoptera litura to spinetoram, and to provide a scientific basis for field resistance monitoring and the development of integrated resistance management (IRM) strategies.【Method】From 2023 to 2024, 23 field populations of S. litura were collected across China. The resistance levels to spinetoram were determined using the leaf-dipping method. The highly resistant Nanning (NN) population and the susceptible strain (SS) were subjected to reciprocal crosses and mass crosses, and the F1 progeny larvae were bioassayed to analyze the resistance inheritance pattern. The synergistic effects of piperonyl butoxide (PBO), diethyl maleate (DEM), and triphenyl phosphate (TPP) were evaluated, and the activities of carboxylesterase (CarE), glutathione S-transferase (GST), and cytochrome P450 monooxygenase (P450) were measured in both the NN and SS strains.【Result】Field resistance monitoring revealed significant variation in spinetoram resistance among different geographic populations of S. litura. High-level resistance (43.3- to 107.8-fold) was detected in populations from Nanning (Guangxi) and Fuzhou (Fujian) in 2023, and from Sanya (Hainan), Kunming (Yunnan), Weifang (Shandong), and Xuchang (Henan) in 2024. Notably, the resistance ratios for the Nanning (2023) and Sanya (2024) populations reached 106.8- and 107.8-fold, respectively. Moderate resistance levels were observed in the 2023 Ningbo (Zhejiang) and Jingzhou (Hubei) populations, as well as the 2024 Fuzhou (Fujian), Jingzhou (Hubei), Guangzhou (Guangdong), Changsha (Hunan), Nanjing (Jiangsu), Shanghai, and Guilin (Guangxi) populations, with resistance ratios ranging from 10.3- to 31.8-fold. Low resistance levels were found in the 2023 Hangzhou (Zhejiang) population and the 2024 Nanchang (Jiangxi), Hefei (Anhui), Beijing, and Hangzhou (Zhejiang) populations, with resistance ratios between 5.0- and 8.9-fold. Inheritance analysis showed that resistance to spinetoram in the NN population was controlled by an autosomal, incompletely recessive gene. The synergists DEM and TPP exhibited synergistic ratios of 1.8 and 1.5, respectively, suppressing resistance in the NN population. Moreover, the activities of GST and CarE in the NN population were 4.1- and 3.5-fold higher than those in the susceptible strain, respectively.【Conclusion】Resistance to spinetoram has developed in S. litura populations across multiple regions. Enhanced activities of GST and CarE play important roles in the resistance of S. litura to spinetoram.
