Abstract

Fourth instar larval was chosen to evaluate the biochemical activity (proteases, Chitinases and α-&β –esterases) of the red palm weevil treated by Beauveria bassiana under laboratory conditions. Biochemical analysis of the haemolymph indicated that the fungus, B. bassiana-9894 increased proteases, Chitinases and α- & β-esterases enzymes level compared with control. The level of total protein was decreased, meanwhile, the total lipids were increased compared with control.
