Abstract :

Toxicological effects of synthetic chemicals such as pesticides are becoming apparent due to their indiscriminate use. Pesticides are presenting as pollutants of biologically active nature in all the ecosystems. Increasing evidences of their potential hazards to human and wildlife are suggesting importance of their toxicity studies. Neonicotinoid (NNT) is a novel class of insecticides used world wide. Similarly these are found to be associated with mass death of honey bees in many countries. Aquatic organisms also get exposed to these class of insecticides as these insecticides are used on crops grown in riverine region. Present study was carried to determine acute toxicity and to assess behavioral effect of a commercial formulation ‘Admire’ NNT group insecticide on freshwater crab. LC0, LC50 and LC100 values for 96 h of this insecticide were observed to be 4.38, 37.12 and 100.46 ppm respectively. Significant behavioral changes were observed with increase in dose concentration.
