Abstract: The distribution of the cellulolytic enzymes namely Endo-β-1,4-glucanase (CX),cellobiohydrolase (CBH) and β-1,4-glucosidase activities in gut and salivery glands of Apriona germari (Hope) was measured.97.13% CX,95.7% β-1,4-glucosidase and 97.03% CBH activities were found in the midgut and not detected in salivary glands.This showed that the major origin of cellulases were endogeneous.

Key words: Apriona germari (Hope), Cellulase, Distribution, Origin
