Cocoon production assessment for Eudrilus eugeniae exposed to monocrotophos (Organophosphorus Insecticides)

The earthworm Eudrilus eugeniae was exposed monocrotophos (MCP) in laboratory controlled soil. Cocoon production was measured over 28 days to determine the impact of MCP. Cocoon production was more sensitive than other parameters such as growth, mortality, etc. Cocoon production was highest in the control to compare with experiments. When the 300ppm MCP concentration is increased 3 numbers of cocoons produced after 14th day and when the duration of exposure is increased of 28 days it revealed 1 number of cocoon at higher concentration of 300 ppm. Our research findings strongly conclude food play a major role in reproduction potential (cocoon production).
