The extracts of Strychnos, Vitex, Lippia and NSP 60 EC possess insecticidal properties. The impact of these extracts on protein, carbohydrate and lipid contents of the leaf webber larva was studied. Among the botanicals tested, the highest reduction of protein content (59.78 %) of the larvae was caused by NSP 60 EC and the lowest reduction was caused by Strychnos (10.25 %). Lippia and Vitex extracts reduced the carbohydrate content of the larvae by 93.38 per cent. Lippia extract caused 91.05 per cent reduction in lipid content however, NSP 60 EC increased the lipid content by 25.79 per cent.

NSP 60 EC reduces protein content in cabbage leaf webber larvae, while Lippia and Vitex extracts reduce carbohydrate content, and NSP 60 EC increases lipid content.
