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 borstlist självhäftande 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 royal nomadic 5413 rug 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.
