Comparison between some digistive Enzymes in the Midgut larvae of nasal Batfly: Cephalopina Titillator clark [Diptera: oestridae] and sheep blowfly lucilia cuprina wiedeman [Diptera: oestridae]

Activities of invertase [alpha-1-2 glucosidase] trehalase [alpha-1-1 glucosidase] cellobiase[beta-1-4 glucosidase] and proteases in the midgut of 3[rd] instar larvae of Cephalopina titillator and Lucilia cuprina were determined. Homogenates from third instar Larval midgut showed the invertase, trehalase, cellobiase, and proteases activity in L. cuprina were more than that of C.titillator and upon using T. test it was found that there was a very high significant difference between the activities of the mentioned enzymes in the two insects. The enzyme activities may be affected by the different habitats of the larvae
