Abstract

Chinese medicinal plants extracts of a group of 30 species from 20 different botanical families, were screened for contact toxicity and antifeedant activities against Spodoptera exigua. The extracts from eight of the Chinese medicinal plants showed strong activity against the insect. The most effective plant extracts were from Litsea cubeba (Lour.) Pers., Brucea javanica (L.) Merr. and Artemisia argyi Lévl. et Vant. Three of the extracts exerted strong antifeedant activity to the insect.

 

Key words: Plant extract, contact toxicity, antifeedant activity, Spodoptera exigua Hübner.
