| Abstract: | Five solvents, namely ethanol, ether, benzene, petroleum ether and acetone were selected to obtain extracts from the stems and leaves of Lycopersicon esculentum Mill..The biological activities of the extracts were tested against Pieris rapae L. in laboratory. The results showed that these extracts had higher antifeeding effect and stomach toxicity against P.rapae. The antifeeding activity and stomach toxicity of ethanol extract were the strongest among the five extracts. |
