Toxic Effect of Organochlorine (Quinalphose) On Earthworms, Essenia Foetida, by Using Filter Paper Contact Test Method

ABSTRAC- Organochlorine (Quinalphose) has been used in agriculture for killing insect which is very poisonous and targeted to non targeted animals like earthworms. In the present study, we investigated the mortality of Organochlorine on the species of Earthworm, Eisenia foetida. The LC50 values will be calculated and it was shown that 150l/850l of Organochlorine concentration was showing 50 % mortality. This mortality compared with the control. This test will show Organocholorine was poisonous for earthworms. We have observed in the test of Organochlorine using the of filter contact test it has been shown affect on earthworm body. The body was folded and very less active after 48 hrs. Periods of test concentration.
