ABSTRACT
Final instar larvae of S. mauritia treated topically on day 0, 1, 2 and day 3 with a daily dose of 20 microg juvenile hormone analogue (JHA) showed an increase in most of the nutritional parameters such as approximate digestibility, efficiency of conversion of ingested food, consumption index and growth rate. Also, the activities of digestive enzymes amylase, invertase, trehalase and protease increased significantly in JHA treated larvae. The supernumerary larvae formed after JHA treatments showed an increase in the activities of digestive enzymes. Neck-ligated larvae treated with 10 microg JHA exhibited a significant increase in the activities of trehalase and protease. The results demonstrate that treatments of JHA increase the activities of digestive enzymes in the last instar larvae of S. mauritia.
