The investigation was based upon the effect of sub lethal (LC0) and semi lethal (LC50) concentrations of the mixture of various agrochemicals (Ekalux EC 25, Cypermethrin 10%, fenvalerate 20% EC, Omite and Lambda Cyhalothrin 2.7% EC) on carbohydrate metabolism in Anbas testudineus (Bloch.) in both sexes during different reproductive periods. The level of serum glucose in both the sexes of A. testudineus (Bloch.) were observed as highly significant (p<0.001) in all the periods with same agrochemicls. The liver glycogen level in both sexes with the mixture of agrochemicals during breeding period is comparatively low but at few occasions no cnosistant results were observed. The levels of muscls glycogen was comparatively high im breeding period than prebreeding and post breeding periods only except in semilethal (LC50) condition. The efficacy of the mixture of agrochemicals is highly significant (p<0.001) in all concentrations.
