Invertase activity in the gut of 6th instar larvae of Spodoptera mauritia Boisd. (Noctuidae, Lepidoptera).

Invertase activity has been studied in the fore-, mid- and hindgut of the 6th instar larva of Spodoptera mauritia. The highest activity was in the midgut except during the early hours of the larva period when the foregut showed comparatively increased activity. The hindgut invertase activity may be from the voiding of enzyme along with the undigested food.
