Spodoptera littoralis is one of the destructive pests that infest several vegetables. Although, the economic importance of vegetable crops, farmers make serious mistakes by burning the leaves of these plants after harvesting. This not only leads to pollution to the environment but also, these leaves contain useful materials that can be used in management the of harmful pests. So, in this study plant extracts of tomato, eggplant, pepper and okra leaves were examined against eggs of S. litttoralis concerning the non-hatching proportion. Data illustrated that tomato leaves extract caused the highest non-hatching proportion followed by eggplant extract then okra extract and pepper extract. GC- Mass analysis proved that phytol is the most abundant compound especially in tomato and pepper leaves extracts while Hexanedioic Acid, Bis(2-Ethylhexyl) Ester is the most abundant compound in eggplant and okraeaves extracts.
