Spodoptera litura is one of the major agricultural pests in China, and it has developed serious resistance to many traditional chemical insecticides. In the present study, the bistrifluron-resistant (Bis-SEL) strain accompanied by a higher oviposition, 113.8-fold RR compared to the bistrifluron-susceptible (Bis-UNSEL) strain, was obtained by bidirectional screening. A comparison of their gonad coefficiency and genes related to oviposition or resistance was used to elucidate the resurgence mechanism.

斜纹夜蛾 (Fab.) (夜蛾科: 鳞翅目) 甲壳素合酶 A 相关的双氟隆抗性的适应性优势

斜纹夜蛾是我国主要的农业害虫之一，对多种传统化学杀虫剂产生了严重的抗药性。在本研究中，通过双向筛选获得了与双氟隆敏感（Bis-UNSEL）菌株相比，双氟隆抗性（Bis-SEL）菌株具有更高的产卵率，RR 113.8倍。比较它们的性腺系数和与产卵或抗性相关的基因来阐明复苏机制。
