Santosh Pawar ^[3] | Ahmad Shahezad ^[2]

Abstract: Chloropyriphose is an organophosphate pesticide which is highly affected on earthworms life or population of earthworm. The objective of this work was to measure the impact of pesticide on earthworm, Eisenia foetida. For the experiment, earthworms were selected on the basis of developed clitellum and they were divided into six groups. Each groups contained ten animals. First group as control group and bed was prepared in distilled water and remaining five groups were experimental groups and prepared single doses of 0.1, 0.2, 0.3, 0.4 and 0.5mg of Chloropyriphos for kilogram of dry soil for each set and exposed it for the duration of 7, 14, 21, 28 and 35 days. In the dose concentrations of 0.1and 0.2 were showed less effect on growth and weight of earthworm for the exposure period of 7 and 14 days, but at the 21, 28, and 35 days of exposure periods and doses concentration of 0.3, 04 and 0.5 were having more effects on weight and growth of worms.
