This study was carried out in ICBS laboratory of Zoology researchers, Department of Zoology, University of Gujrat, Pakistan from April 2015 to August 2015. Analysis has been made to evaluate the effect of different concentration of lambda cyhalothrin on histopathology of stomach and heart of frog, Rana tigrina. In this study 24 frogs divided into 4 groups, 6 for each group. One group was control being untreated group while remaining received low, medium, and high doses respectively. A morphological and histopathological study reveals, it adversely affects the stomach and heart of frog that leads to limited ages of frog species and ultimate cause reduction in population size. Results suggested that these animals are sensitive to lambda cyhalothrin; therefore measures must be taken to secure these animals otherwise pernicious effects of agrochemicals will lead to extinction of this group.
