秋粘虫是一种广为人知的重要粮食作物害虫，已对多种杀虫剂产生抗药性。2019年，它入侵了四川省的中国。在这项研究中，我们对11个田间采集的四川种群进行了杀虫剂抗性监测，所有种群都对阿维菌素苯甲酸酯和毒死蜱敏感。这些种群对吲哚杀威(RR)9.23~45.53倍，多菌灵(RR)4.32~18.05倍，氯氰菊酯(RR)2.02~10.39倍有不同程度的抗性。为了探讨氯氰利普利的抗性机制，进行了增效试验，结果表明，胡椒基丁氧基对QJ-20种群中抗性(RR)为1.43倍(RR)的处理组与未加增效剂的处理组相比，具有轻微的增效作用(RR为10.39倍)。此外，抗性相关基因的表达扫描显示，5个P450基因(CYP6AE43、CYP321A8、CYP305A1、CYP49A1和CYP306A1)和兰尼定受体基因(RyR)在QJ-20群体中过表达。这些结果表明，四川秋粘虫对几种杀虫剂表现出不同的敏感性，RyR和几个P450基因的过度表达可能参与了果蝇对氯氰菊酯的抗性形成。
The fall armyworm, Spodoptera frugiperda (Noctuidae: Lepidoptera), is a wide-reaching notorious insect pest of important cereal crops, which has developed resistance to multiple classes of insecticides. It invaded the Sichuan Province of China in 2019. In this study, we performed resistance monitoring of insecticides for 11 field-collected populations from Sichuan, and all the populations were susceptible to emamectin benzoate and chlorpyrifos. The variations in resistance level to indoxacarb (resistance ratio (RR), 9.23–45.53-fold), spinetoram (RR, 4.32–18.05-fold), and chlorantraniliprole (RR, 2.02–10.39-fold) were observed among these populations. To investigate the resistance mechanism of chlorantraniliprole, synergism tests were performed and showed that piperonyl butoxide had a slight synergistic effect on chlorantraniliprole for the QJ-20 population (1.43-fold) in moderate resistance (RR, 10.39-fold) compared with the treatment group without synergist. Furthermore, the expression scanning for resistance-related genes showed that five P450 genes (CYP6AE43, CYP321A8, CYP305A1, CYP49A1, and CYP306A1) and the ryanodine receptor gene (Ryr, chlorantraniliprole target) were overexpressed in the QJ-20 population. These results indicated that the fall armyworm in Sichuan has exhibited diverse susceptibilities to several classes of insecticides, and the overexpression of Ryr and several P450 genes may contribute to the development of resistance in S. frugiperda to chlorantraniliprole.
