摘要

Leaf extracts of the plants, Vitex negundo, Withania somnifera, Tridax procumbens and Cassia bra were screened against Callosobruchus chinensis at concentrations of 0.12 mg, 0.25 mg and 0.5 mg/g seed. Extract of V. negundo and W somnifera at 0.5% were more effective, causing 100% adult mortality and progeny suppression. T. procumbens and C. tora extracts showed less oviposition deterrence compared to the other two
