Abstract:
Crop loss is a regular feature associated with the Indian sericulture caused by various factors with major reasons being the outbreak of different diseases, parasitic attacks and fluctuations in the environmental conditions. The productivity of silkworm, Bombyx mori is adversely affected by various pathogens that cause considerable yield loss to silkworm rearers.
Among the various diseases, pebrine caused by protozoa, the microsporidian Nosema bombycis is one of the most important pathogen causing majority of damage to the sericulture industry. The present study was conducted to study the effect of microsporidian (Nosema bombycis) on the commercial and economic parameters in six races of silkworm, Bombyx mori viz; SK1, SK6, SK28, SH6, NB4D2 & CSR2. The results of the study elucidated that the commercial and economic parameters of the silkworm races under study were adversely affected due to the pebrine disease. Among the six races under study SH6 race showed least effect due to the microsporidian infection and the race SK28 suffered the maximum loss in terms of all parameters under study.
