Abstract

In the present study, acute toxicity of the organophosphate pesticide, diazinon, was evaluated under experimental condition to Oligochaete worm, Branchiura sowerbyi. The 96 h LC50 with 95% confidence limits of B. sowerbyi was 2.87 (2.50–3.17) mg/l. None of the unexposed control worm died during the experiment. Mortality rate between each dose and mortality rate between 24–96 h depending on time was correlated. The mortality rate also varied significantly (p<0.05) with the increasing concentration for the organisms at all the exposure concentrations except 6.00 mg/l, 6.50 mg/l and 7.00 mg/l (p>0.05) at all the exposure times. The relationship between mortality rate and exposure times was found to be significant (p<0.01). The effect of toxicant on the behavioral changes of the Oligochaete worm was directly proportional to the increasing concentration of diazinon.
