斜纹夜蛾是四川蔬菜的主要害虫之一，中国对多种传统化学杀虫剂产生了严重的抗药性。本研究于2017年对四川5个地区采集的斜纹夜蛾个体进行了抗药性检测。我们发现，与实验室敏感株(Lab-HN)相比，双氟隆的抗药性比率(RRS)分别为15.9-77.7倍。为了阐明双氟隆对斜纹夜蛾生活史参数的影响，我们以DY田间种群为基础，建立了双氟隆敏感品系(Bis-unsel)和抗性品系(Bis-SEL)，与实验室HN品系相比，DY田间种群对Bistrifluron的RR值最高，为77.7倍。结果表明，Bis-SEL品系的RR是Lab-HN品系的113.8倍，而Bis-unsel品系的RR几乎与Lab-HN品系相当(LC_(50)值有重叠的可信区间，P
Spodoptera litura is one of the major insect pests of vegetables in Sichuan, China, and it has developed serious resistance to many traditional chemical insecticides. In this present study, S. litura individuals collected from five regions in Sichuan in 2017, which were detected the resistance to bistrifluron. We found that the resistance ratios (RRs) bistrifluron were in the ranges of 15.9- to 77.7-fold, respectively, compared with a laboratory susceptible (Lab-HN) strain. To elucidate the effect of bistrifluron on the life history parameters of S. litura, we established the bistrifluron-susceptible (Bis-UNSEL) and bistrifluron-resistant (Bis-SEL) strains based on the DY field population with the highest RR of 77.7-fold among the all field populations to bistrifluron compared with a laboratory Lab-HN strain. The results show that the Bis-SEL strain developed a 113.8-fold RR while that of the Bis-UNSEL strain was almost equal to that of the Lab-HN strain (with overlapping confidence intervals (CI) of their LC50 values, P
