Abstract

              In the earlier investigation, silkworm (Bombyx mori L. Lepidoptera, Bombycidae) was used to examine some nutritional additives. The corresponding concentrations were 8, 0.01, 0.3 and 0.07 mg/ml for vitamins mixed, ascorbic acid, delzosin and nitrogen respectively. The results showed that, the best treatment for day after day nutritional dosage was a concentration of 8 mg/ml of vitamins mixed. The control group averaged 60.53 mg/ml of total hemolymph protein, whereas the best averaged 77.11mg/ml. protease enzyme level averaged 64.17µg alanine/min/ml, while control group level average 50.64 µg alanine/min/ml. The average number of eggs produced by female in the treatment group was 264, while the average number of eggs produced by female in the control group was 236. The average hatching percentage for the treatment was 95.78%, whereas the control group 81.29%. The previous results suggests that dietary supplements have positive effects on silkworm and are essential for improving the insect's rearing performance as they led to an improvement in insect characteristics.
