Abstract

Global decline of the amphibian population has become a major ecological concern. With extensive application of pesticides within agricultural proximity, the inhabiting fauna is subjected to greater risk. The present study was aimed to determine the acute toxicity and elucidate the responses of Dattaphrynus melanostictus tadpoles to three sublethal concentrations of commercial formulated chlorpyrifos (CPF). While 96 hours LC50 was noted to be 5.9mg/l, tadpoles on exposure to 0.7 (1/8th), 1.1 (1/5th) and 1.9 mg/l (1/3rd) of CPF for a duration of five days indicated significant (p
