Abstract

The toxic effect of three chemicals ,were isolated from plants , Anaphalis margantacea , Chenopodium ambrosioides and Ambrosia maritime against the second and fourth instar larvae of the cotton leafworm, Spodoptera littoral/s was bioassayed in the laboratory tests. The molecular formula of these cheinicals were C,5H1204, C271-1,00,4 and C1ell1s07 ,respectively .The 2w and 4' instar larvae were left to contact for 24h with the residual film of each chemical at different concentrations. The first chemical (C1511,204) was the most toxic against the two instar larvae with LC55 values of 6 and 28 P.P.M. for both instars , while the third chemical was the least toxic one with LCSO values of 60and 84 P.P.M. for the two instar larvae, respectively. The biological parameters of the treated larval instars were obviously affected specially with the first chemical. Therefore, the larval and pupal duration were prolonged, the pupation and adult emergence percentages were decreased, the pupal weight was reduced. Also, the fecundity and fertility were retard ,arid the longevity was shorted ,also the sex ratio of the emerged adults was shifted in respect to control The Pupal and. adult malformation percentages were recorded as a result of the , larvae treated of 4th instar with these chemicals at the LC50 values.
