Evaluation on the Sensitivity of the Freshwater Tropical Worm, Branchiura sowerbyi (Beddard, 1892) to the Pyrethroid Pesticide, BifenthrinBy Shubhajit Saha, Kishore Dhara, Nimai Chandra Saha
Abstract: In the present study, acute toxicity of the pyrethroid pesticide, bifenthrin, was evaluated under the experimental condition to the freshwater tropical oligochaete worm, Branchiura sowerbyi. The 96 h LC50 with 95% confidence limits of B. sowerbyi was 1.043(0.721-1.327) μg/l. None of the unexposed control test animal died during the experiment. Relation between each concentration and mortality rate during 24–96 h was found to be correlated. The mortality rate varied significantly …

Acute Toxicity and Behavioral Alterations of Oligochaete Worm, Branchiura sowerbyi Exposed to DiazinonBy Shubhajit Saha, Nimai Chandra Saha, Dip Mukherjee
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 …
