Abstract
The effects of five insecticides-metasystox, malathion, folithion, rogor and metacid -on eggs, feeding stage and limb bud stage tadpoles were determined. By chronic exposure to descending concentrations of each insecticide, the threshold levels for continuation of development and metamorphosis were determined. In general, at concentrations much lower than the dosage recommended for field application, the insecticides caused a prolongation of life history and a reduction in size at metamorphosis.
