Abstract
The antifeedant and insect growth-regulating activities of salannin, n imbin, and 6-deacetylnimbin, in comparison with azadirachtin-A, have b een studied against Spodoptera litura, Pericallia ricini, and Oxya fus covittata. Salannin deterred feeding, delayed molt by increasing larva l duration, caused larval and pupal mortalities, and decreased pupal w eights in the two lepidopterans. Salannin also caused molt delays and nymphal mortalities in Oxya fuscovittata. The role of salannin and oth er compounds in conferring bioactivity, along with azadirachtin-A, to neem oil/neem seed extracts is emphasized.
