Thiamethoxam induced histopathological alterations in hepatopancreas of freshwater bivalve Parreysia cylindrica

Abstract

Freshwater bivalves, Parreysia cylindrica were exposed to acute and chronic dose of thiamethoxam so as to study the histopathological effects of pesticide on hepatopancreas. The histopathological studies have shown that the thiamethoxam has affected the hepatopancreas when compared with their respective control. Severe damages were found in hepatopancreas of pesticide exposed bivalves. Intensity of damage in the tissues of pesticide exposed bivalves was found to be increased with increase in exposure period.
