Growth Inhibitory Activities and Feeding Deterrence of Solanaceae-Based Derivatives on Fall Armyworm

Spodoptera frugiperda is a pest of worldwide importance, responsible for significant economic losses, mainly in maize crops. The use botanical derivatives emerges as promising alternative to control this insect pest. In work, we evaluated the effect ethanolic extracts (EE) and semi-purified fractions Acnistus arborescens Datura stramonium (Solanaceae) on biological development S. effects feeding behavior 4th instar caterpillars. Crude caused lethal sublethal effects, namely increasing both duration larval pupal stages well deformities adults, decreasing weight pupae. turn, deterrence were more pronounced treatments with A. fractions. Our results highlight potential EE from solanaceous species source allelochemicals that can be used integrated management frugiperda.
