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.). |
