| Abstract |
An investigation was conducted under laboratory condition to study the effect of Neemazal T/S 1 % Azadirachtin (AZA) on mortality., pupation, adult emergence and malformation when the newly hatched larvae of Pnctinophora gossypiella PBW exposed to treated diet,as well as the latent effect of AZA on fecundity, fertai'-y and longevity of adult moths derived from treated larvae.
Neemazal T/5 adversely affect larval morality in a dose and time, where the cunnalative larval mortality increase by the time reached to 85.27 % at 130 ppm after 20 days. Neemazal also influences larval and pupal development resulted morphological deformation, reduction larval and pupal weight gains and severe reduction in fecundity, fertility and longevity of the resulted moths.
The biochemical effect of AZA on total carbohydrate, lipids and protein, in addition to the level of nucleic acid in larvae of 10 and 13 days age fed as newly hatched larvae on treated diet were studied. AZA treated larvae resulted in a decrease in total carbohydrate and increase in all other chemical composition examined in the larvae of ten days age at LCSp concentration, most of these component decreased in the larvae of 13 days compared with control. These chemical changes explained reduction in reproductive potentiality and larval and pupal weight gains
