dc.description.abstractPebrine, caused by Nosema bombycis N. is a serious disease of mulberry silkworm, Bombyx mori L. The disease is an important production constraint of silk in the Kashmir valley. In the present study, conducted in three different Sericultural Zones of Kashmir valley viz., North Zone (Baramulla-Kupawara),Central Zone (Srinagar-Budgam) and South Zone (Anantnag-Pulwama), the disease was found prevalent throughout the Sericultural map of the valley but at varying levels of incidence. The existing rearing practices in the valley were found to have a greater influence on this disease. For the isolation of pebrine pathogen through the process of centrifugation, maximum sedimentation of spores took place when the centrifugation was carried out at 5000 revolutions for 5 minutes. Among various stains used Safranin, Malachite green and Methyl blue effectively stained the spores whereas Hematoxylin and Eosin gave better visibility when both these stains were applied to the same smear. All the test chemicals/antiprotozoan drugs evaluated at different concentrations for their influence on fecundity and hatching of B. mori were found to record significantly low fecundity (eggs/female) and hatching percentage as compared to check-I and check-II.en_US
