| Abstract: | The results showed that the extracts of foliage, seed, and root-cortex of Vitex negundo contain some insecticidal activity against pests, but the primary insecticidal activity were in foliage and seed. The extracts of dimethylbenzene in foliage, not only had the higher insecticidal activity against Pieris rapae(L.), Prodenia litura (Fabricius), and Myzus persicae (Sulzer) of which the LC50 values was 186 times, 259 times, and 371 times respectively, but also had the more anti-feeding effect against Pieris rapae(L.). |
