Behavioral, morphological deformities and biomarkers of oxidative damage as indicators of sublethal cypermethrin intoxication on the tadpoles of D. melanostictus (Schneider, 1799)

► Acute toxicity treatments showed strong negative effects on survival of D. melanostictus. ► Cypermethrin toxicity was concentration and time dependent. ► D. melanostictus exhibit behavioral and morphological anomalies on exposure to cypermethrin. ► Sublethal concentration of cypermethrin induces oxidative damage in D. melanostictus.
