Effect of Murraya paniculata (L.) Jack Extract on the Adult Mortality of Callosobruchus maculatus F. (Coleoptera: Bruchidae)

Leaf, stem and root of Murraya paniculata (L.) Jack was extracted in four different organic solvents (petroleum ether, ethyl acetate, acetone and methanol). The extracts were tested on the mortality of adult male and female of Callosobruchus maculatus F. All the evaluated extract was toxic to both the sexes. Males generally showed higher susceptibility compared to females. Petroleum ether extract was more toxic than others. It was in the order: pet. ether>EtOAc>acetone>MeOH extract. Leaf extract was most toxic in comparison to stem and root extracts. It was in order: Leaf>root>stem. Generally, 72 hours exposure exhibited lower LD50 values compared to 24 and 48 hours.
