Abstract

Forty three crude-extracts from 40 plant species were bioassayed in vitro on the insecticidal activity to the third instar diamondback moth larvae. The highly effective insecticidal activities (80-100% mortality of larvae at 40 mg/ml of crude-extract) were found in Abrus precatarius Linn., Acorus calamus Linn., and Duranta repens Linn. The moderate insecticidal activities (60-79% mortality of larvae) were observed in Aglaia odorata Lour. And Bixa orellana Linn. The low activity (40-59 % mortality) was shown in Cassia spectabilis DC. and the very low activity ( 20-39% mortality) in Andrographis paniculata Wall ex Nees.
