| Abstract: | Experiments with extracts of the seed kernels of Melia azedarach by somesovents in laboratory and green house shows that their potential as strongselective antifeedants aind non-selective antifeedants against cabbageworm. Ofthem chloroform extracts and petroleum ether extracts have stronger effectthan ethanol extracts, water extraces and Chinaberry (Melia azedarach L.)seed oil, but poorer effect than toosendanin. The median selective antifeedantconcentration (AFC_(50)) for the third instar Cabbageworm was determined tobe, 1.068% for chloroform extracts, 2. 0% for petroleum ether extracts, 2.18%for M. azedarach seed oil and 0.0428% for toosendanin. |
