Abstract
Biodiversity is a popular issue today. Vast biodiversity is available on our planet from ancient time. Among al groups, insects are very important for ecosystem. Insects are worthy for human beings by many ways viz. - help in pollination, production of useful substances etc. However, many of these insects are very harmful to us in many ways like destroy our crops, stored food products, cause of dreadful diseases. Common categories of pesticides are organophosphate, organochlorine and carbamate which are common pesticides in country and used externally to control this destruction. Now it is necessary to test the potency of pyrethroid for indoor use which are safer comparatively. The present study reveals pyrethroid sample lambda-cyhalothrin tested in Drosophila melanogaster, a dipteran insect. After treatment, a significant change in morphological parameters like decreased larvae number and darkening of caterpillars front and morphometrical changes i.e. decrease in length of larvae, weight of larvae and adult fly weight of Drosophila melanogaster. The obtained data were statistically signified to confirm the biological and appropriate importance of the research work conducted.
