Abstract

The biochemical effect of stored mulberry leaves used in feeding Bombyx mori larvae on the haemolymph enzymes was investigated. Nine enzymes were dertermined namely; acid and alkaline phosphatase, alpha and beta esterases, G.O.T, G.P.T., amylase, trehalase and invertase. The haemolymph enzymes revealed clear differences between larvae fed on fresh and stored leaves. Acid phosphatase, GPT and amy­lase activities decreased, whereas trehalase activity increased as affect­ed by mulberry leaves storage. On the other hand . alkaline phosphatase. alpha and beta esterases , GOT. and lnvertase activities increased firstly then decreased thereafter.
