چکیده انگلیسی
In an attempt to assess the effects of chlorpyrifos [O,O-diethyl O-(3,5,6-trichloropyridin-2-yl) phosphorothioate], the second largest selling insecticide in India, studies were made with reference to some non-target organisms. The present study was undertaken to evaluate the effects in the embryos of Duttaphrynus melanostictus caused by the commercial formulations of chlorpyrifos (Tricel, chlorpyrifos, 20% EC). The LC50 value for Duttaphrynus melanostictus embryos after 48â¯h (h) of treatment with chlorpyrifos was found to be 57.525â¯ppm. The mortality of the embryo was significantly affected by different concentrations of chlorpyrifos when compared with the control groups. An increase in concentration of chlorpyrifos resulted in the simultaneous decrease of the hatching percentage and an increase in the morphological abnormalities such as compression of the embryo, reduced body size and curling of tail.
