Pulses, which are the richest source of proteins, are under serious threat from bruchid pest during storage. Severe losses have been caused by Callosobruchus species in store houses (Sharma 1984). Leaf extracts of Tabernaeomontana livaricate (Chandni) and Tamarindus indica (Imli) in acetone were found to be an effective anti-feedent and adulticidal agent against Callosobruchus chinensis. The loss in seed weight was minimum (0.46 gms and 1.37 gms) at 100% concentration of Tabernaemontana and Tamarindus, respectively. Percent adult mortality was 72.9% in Tabernaemontana and 67.6% in Tamarindus.
