Abstract:
The results of the present study indicated that fifth instar larval duration was short in SH6 (173.01h) and Nistari (149.70h) during spring and summer respectively. Total larval duration was recorded shortest in NB4D2 (645.56h) during spring, however during summer it was short in Nistari (501.16h). SKUAST-28 recorded the shortest total larval duration of 667.97h among the bivoltines during the same season. Significantly higher cocoon yield by number (9116.50 cocoons/10,000 larvae) and by weight (16.95 kg) was recorded by SKUAST-28 during spring, while during summer cocoon yield by number was high in Nistari (9399.87cocoons/10000 larvae).
