草地贪夜蛾（Spodoptera frugiperda，J.E. Smith）（鳞翅目：夜蛾科）是巴西玉米作物的主要害虫。植物代谢物对昆虫生物学和行为的影响的研究很少。该研究的目的是通过使用含有芦丁的人工饲料来评估芦丁对草地贪夜蛾生物学的活性。该研究评估了四种治疗方法：常规饮食（对照组）和含有 1.0、2.0 和 3.0 mg g(-1) 芦丁的饮食。每天评估幼虫的以下生物学变量参数：发育时间（天）、幼虫和蛹重量（克）和活力（%）、成虫寿命和总生命周期（天）。采用完全随机的实验设计，重复 25 次。芦丁类黄酮通过延长幼虫发育时间、减轻幼虫和蛹的重量以及降低蛹的活力，对草地贪夜蛾的生物学产生负面影响。添加不同浓度的芦丁延长了草地贪夜蛾的生命周期。利用具有杀虫活性的植物在病虫害综合治理策略方面具有潜力。
The fall armyworm Spodoptera frugiperda (J.E. Smith) (Lepidoptera: Noctuidae) is a major pest of maize crops in Brazil. The effects of plant metabolites on the biology and behavior of insects is little studied. The aim of the study was to evaluate the activity of rutin on the biology of the S. frugiperda by using artificial diets containing rutin. The study evaluated four treatments: regular diet (control group) and diets containing 1.0, 2.0 and 3.0 mg g(-1) of rutin. The following biological variables parameters of the larvae were evaluated daily: development time (days), larval and pupal weight (g) and viability (%), adult longevity and total life cycle (days). A completely randomized experimental design was used with 25 replication. The rutin flavonoid negatively affected the biology of S. frugiperda by prolonging the larval development time, reducing the weight of larvae and pupae and decreasing the viability of the pupae. The addition of different concentrations of rutin prolonged the S. frugiperda life cycle. The use of plant with insecticidal activity has the potential with strategy in IPM.
