Toxicidade do inseticida Tiametoxam para o Pacamã(Lophisiolurus alexandri)

This research evaluated acute and chronic toxicity of a thiamethoxam insecticide for Pacama ( Lophisiolurus alexandri ), assessing the LC50 and liver histopathological changes in animals exposed for 96 hours and 15 days. Therefore, were used 120 fingerlings subjected to five different concentrations (30, 60, 120, 240 and 480mg/L) for 15 days with two sampling times, 96 hours and 15 days. There was no significant mortality during the experimental period, however the animals showed changes as vacuolation, congestion and necrosis. The LC50 was determined as greater than 100mg/L, considered practically non-toxic. Necrosis was the more significant change in exposed animals, with increasing occurrence in chronic toxicity test.
