Abstract
Ten of 13 selected substrates were hydrolyzed by crude extracts of midguts from larvae of Heliothis zea (Boddie). Sucrose was the most readily hydrolyzed; raffinose, melezitose, trehalose, glycogen, starch, melibiose, maltose, inulin, and α-methyl glucoside were less readily hydrolyzed. Cellulose, cellobiose, and lactose were not hydrolyzed. The pH optimum for each substrate was determined. Thin-layer chromatography showed that a β-fructosidase occurs in the midgut. Sucrase activity and pH of gut contents were determined each day for 5- to 11-day-old larvae.This publication has 1 reference indexed in Scilit:
