چکیده
|
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.
