Toxicity of the insecticide chlorpyrifos to the South American toad Rhinella arenarum at larval developmental stage

Highlights • Rhinella arenarum is exposed to relevant pesticide amounts during the reproductive season. • Chlorpyrifos is teratogenic and causes lethal effects on R. arenarum larvae at ppm range. • Esterases are early inhibited by sublethal (1/10 LC50) chlorpyrifos levels. • Sublethal chlorpyrifos c...
