Abstract

Tuta absoluta is one of the most destructive and invasive insect pests throughout the world. It feeds on numerous solanaceous plant species and has developed resistance to most types of popular insecticides. Tetraniliprole is a novel diamide chemical agent that acts as a modulator of the ryanodine receptor. To establish T. absoluta susceptibility to tetraniliprole and to understand potential mechanisms of resistance, we monitored 18 field populations of T. absoluta collected from northern China. One field-evolved resistant population, Huailai (HL), showed moderate resistance to tetraniliprole (36.2-fold) in comparison with susceptible strain YN-S. Assays of cross-resistance, synergism, metabolic enzyme activity, and inheritance of resistance were performed with YN-S strain and HL population. The latter displayed 12.2- and 6.7-fold cross-resistance to chlorantraniliprole and flubendiamide, respectively, but little cross-resistance to broflanilide (1.6-fold), spinosad (2.1-fold), metaflumizone (1.5-fold), or indoxacarb (2.8-fold). Genetic analyses revealed that tetraniliprole resistance in HL population was autosomal, incompletely dominant, and polygenic. Piperonyl butoxide was found to significantly increase tetraniliprole toxicity, and enzymatic activities of P450 monooxygenase and glutathione S-transferase were significantly higher in HL than YN-S population. These results enhance our knowledge of the inheritance and mechanism of tetraniliprole resistance, enabling future optimization of resistance management strategies.

摘要

烟实夜蛾是世界范围内极具破坏性和侵袭性的昆虫之一。它以多种茄科植物为食,并对大多数类型的常用杀虫剂产生了抗性。四氯虫酰胺是一种新型双酰胺类化学药剂,作为肌醇三磷酸受体调节剂而起作用。为了确定烟实夜蛾对四氯虫酰胺的敏感性,并了解潜在的抗性机制,我们监测了来自中国北方的 18 个烟实夜蛾田间种群。一个田间进化的抗性种群(怀来,HL)与敏感品系 YN-S 相比,对四氯虫酰胺表现出中等抗性(36.2 倍)。我们使用 YN-S 品系和 HL 种群进行了交叉抗性、增效作用、代谢酶活性和抗性遗传的测定。后者对氯虫苯甲酰胺和氟苯虫酰胺的抗性分别为 12.2 倍和 6.7 倍,但对溴虫氟苯酰胺(1.6 倍)、多杀菌素(2.1 倍)、甲氧虫酰肼(1.5 倍)或茚虫威(2.8 倍)的交叉抗性很小。遗传分析表明,HL 种群对四氯虫酰胺的抗性是常染色体的、不完全显性的和多基因的。增效醚被发现能显著增加四氯虫酰胺的毒性,而 HL 种群的 P450 单加氧酶和谷胱甘肽 S-转移酶的酶活性明显高于 YN-S 种群。这些结果增强了我们对四氯虫酰胺抗性遗传和机制的认识,使未来能够优化抗性管理策略。
