Abstract: Earthworm, the Intestine of Earth plays a vital role in providing nutrients to soil increasing its
fertility potential. This study was done to study the impact of chloropyrifos pesticide on different
biological parameters of LampitomauritiiKinberg. Subtoxic concentration of chloropyrifos such
as 5ppm, 10ppm, 20ppm brought significant changes insurvivility, growth, feeding, regeneration,
respiration and excretion as compare with 0ppm dose. The values of these parameters decreased
significantly with the increasing dose of the input pesticide, when statistically observed |
