EFFECT OF PESTICIDES ON AMYLASE ACTIVITY IN FORAGERS OF APIS MELLIFERA L. UNDER LABORATORY CONDITIONS

SUSHIL KUMAR

Abstract

The effect of sub lethal concentrations of three organophosphates (Dimethoate – 30 EC, Malathion – 50 EC and Quinalphos – 35 EC) and one biopesticide (neem oil – 25 EC) on the activity of digestive enzyme Amylase in foragers of Apis mellifera L was studied. The experiments were performed in laboratory conditions. The data obtained from treated groups of bees revealed that all the pesticides reduced the Amylase activity. The results suggested that organophosphates (Dimethoate, Malathion and Quinalphos) had great inhibitory action on amylase activity. Neem oil a biopesticide, showed insignificant inhibitory effect. The maximum inhibition was observed for Dimethoate followed by Malathion, Quinalphos, Neem oil.
