西花蓟马Frankliniella ococcuentalis（Pergande）是一种重要的农业害虫。在田间种群中已检测到高抗性。对杀虫剂多杀菌素的效果。本研究比较了多杀菌素敏感（Ivf 03）和多杀菌素抗性（NIL-R）近等基因系的生活史性状、体尺和摄食行为。[咒语]生命表分析表明，NIL-R降低了雌性寿命，降低了繁殖力。NIL-R的相对适合度（0.43）小于Ivf 03的一半。NIL-R个体在各发育阶段的体长和体宽均小于Ivf 03个体。在NIL-R中，摄食活动的数量和持续时间显着减少，但长时间摄食探针的总持续时间除外。这些结果表明，存在一个适合度权衡与多杀菌素抗性在F。多杀菌素与其他缺乏交叉抗性的农药轮换使用，可能会减少这种害虫的抗性发展。
Abstract Frankliniella occidentalis (Pergande) is an economically important pest of agricultural crops. High resistance has been detected in field populations of F. occidentalis against the insecticide spinosad. In this study, we compared life history traits, body sizes, and feeding behaviors (recorded via an electrical penetration graph) of spinosad-susceptible (Ivf03) and spinosad-resistant (NIL-R) near-isogenic lines of F. occidentalis. Life table analysis showed that NIL-R had reduced female longevity and reduced fecundity. The relative fitness of NIL-R (0.43) was less than half that of Ivf03. NIL-R individuals were smaller than Ivf03 individuals, both in body length and body width at every stage. The number and duration of feeding activities were significantly reduced in NIL-R, with the exception of total duration of long-ingestion probes. These results suggest that there is a fitness tradeoff associated with spinosad resistance in F. occidentalis, and that the development of resistance in this pest species may be reduced by rotating spinosad with other pesticides lacking cross-resistance.
