Acute toxicity of apple snail Pomacea canaliculata’s eggs on Rhinella arenarum tadpoles

The effect of the crude homogenate of snail Pomacea canaliculata’s eggs (CHSE) exposition on Rhinella arenarum tadpoles was investigated. Exposure to 10 g CHSE/L treatment produced 95% tadpole mortality, whereas the median lethal concentration (48-h LC50) was 4.35 g/L. Moreover, CHSE inhibited significantly the activities of acetylcholinesterase (AChE) and glutathione-S-transferase (GST) with respect to control tadpoles, and modified tadpoles swimming behavior. Together all these evidences indicate that eggs of snail P. canaliculata have a neurotoxic effect on tadpoles limiting survival at low concentrations and short time exposition.
