T e results revealed t at, t ere w ere 10 digestive en zymes inM onocham us a ternatus and 8 in Tom icus p inpi erda. T e activity order of enzymes of larvae ofM onocham us a ternatus arranged as pectinase amylase endo1, 4glucanase ( Cxase) em icellu lase invertase 1, 4 glucosidase exo1, 4glucanase ( C1ase) lipase trypsinlike enzym e pepsin; and for larvae and adu lts of Tom icus p in pi erda, t e activity order of enzymed arranged aspectinase amylase em icellulase invertase exo 1, 4glucanase( C1ase) trypsinlike enzyme lipase pepsin. T ere w ere no Cxase and 1, 4glucosidase for bot larvae and adu lts ofTom icus p inip erda. T e resu lt pectinase a
