Bullfrog (Rana catesbeiana) tadpoles were exposed to malathion in water in a 28‐d static renewal test. The effects of malathion on survival, growth, development, and loss of equilibrium posture were determined. Survival was significantly decreased at malathion concentrations of 2,500 μg/L and higher...
