Effects of carbaryl on the aminotransferases in the mid gut of blister beetle,Mylabris pustulata (Thunb)

The activity levels of aminotransferases such as alanine aminotransferases (AlAT), aspartate aminotransferases (AAT), isoleucine aminotranferases (IlAT), leucine aminotransferases (LAT), valine aminotrasferases (VAT) were measured in the mid gut of the blister beetle; Mylabris pustulata (Thunb) exposed to sublethal doses of carbaryl. The insecticide markedly inhibited the activity levels of all aminotransferases exposed for either short or prolonged treatments. The beetles regained normal enzymic activity after withdrawal from the treatment. It is possible that chronic exposures of beetles to carbaryl may induce impairment in protein synthesis in the mid gut of the beetle.
