Description
Summary:Recently, Spodoptera litura (Fab.) has emerged as a significant threat to the environment. Because of the pest's ability to spread, pesticides are often applied to agricultural crops. By combining certain plant extracts with other compounds, both a reduction in insect infestation and an increase in production could be achieved. The antifeedant, larvicidal and histological effects of Solanum torvum (Sw.) leaf extracts were investigated against S. litura . The study found that the ethyl acetate leaf extract showed a significant antifeedant effect against S. litura of (86.16%) at 5% concentration. Ethyl acetate extract showed larvicidal activity against S. litura of 88.21% and the LC50 value was 2.05%. Exposure of larvae to ethyl acetate leaf extract resulted in significant histological damage, particularly affecting epithelial, goblet and digestive cells. The results suggest that the inclusion of these plant extracts in integrated pest management approaches can promote sustainable and environmentally friendly pest control methods in agriculture.
