Abstract :
The toxicity of Murraya paniculata (L.) leaf-derived petroleum ether fractions (P1- P13) and ethyl acetate fractions (E1-E27) were evaluated by a residual film bioassay against adult male and females of Callosobruchus maculatus (F.). Petroleum ether fraction P1 was more toxic than ethyl acetate fraction E1. The 24-, 48- and 72- h LD50 values for P1 and E1 were: 11537.78, 1890.05, 347.02 and 26698.99, 5026.88, 411.14 ng/cm^2 (male) and 28227.67, 5809.14, 431.81 and 44838.78, 6691.01, 522.51 ng/cm^2 (female) respectively. Males were more susceptible than females. M. paniculata leaf-derived materials merit further study as potential insect-control agents for C. maculatus.
