Potential of <i>Achyrocline satureioides</i> Ethanolic Extract in the Control of <i>Spodoptera littoralis</i>

Abstract

The species Spodoptera littoralis is one of the most destructive agricultural pests in tropical and subtropical areas, causing significant losses to farmers; alternative forms of control are therefore necessary. This study aims to evaluate ethanolic extracts from leaves and inflorescences of Achyrocline satureioides as a potential control agent for Spodoptera littoralis. The ethanolic extract was prepared via maceration and a bioassay was carried out in five replications with sixth instar S. littoralis larvae, using the Food Deterrence methodology; the larvae continued to feed until they had eaten 75% of the control or sample. The results demonstrated that the extracts from A. satureioides leaves and inflorescences at a concentration of 10 mg/mL inhibited 37.23% and 22.72% of S. littoralis feeding, respectively, indicating that the extracts have an inhibitory effect.
