| ABSTRACT |
| As lead is an important environmental noxious waste which directly or indirectly contaminate the foods, soil water, and
air thus, insects could be influenced easily by the lead. Therefore, lead was studied as lead acetate in different doses. viz
0.125 mg., 0.25 mg., 0.5 mg, 01 mg and 02 mg, on external morphology on Drosophila melanogaster at 48 hours post
treatment. It was observed that under the effects of lead abnormalities and deformity were developed in the larvae of
flies. Morphological changes were observed as elongated wings, de-shaped wings, elongated and folded legs, change in
color of larvae, pupae and adults. Some other structural abnormalities of larvae and pupa shape were also observed. Thus
the Dipterous flies could present a useful module for the quick transmission of the environmental hazards due to lead
contamination, which exerts a specific physiological and morphological effect on these flies. So, in this respect,
Drosophila melanogaster, could be used as a test method for heavy metals effects. |
