Multiple cellulolytic and xylanolytic activities were assayed in major gut regions of Coptotermes formosanus (Shiraki) workers kept on three diets: red oak (Quercus spp.), pine (Pinus spp.) and filter paper. Cellulolytic activities assayed were endoglucanase, exoglucanase and beta-glucosidase. Xylanolytic activities assayed were xylanase and beta-xylosidase. Assays were conducted separately on homogenates from the foregut, midgut and hindgut in all cases.
