Incidence of diseases and pests is a serious concern in silk production due to prevailing tropical condition. Annual crop loss due to diseases during rearing varies between 15% and 20% in national level and in West Bengal it ranges between 35.7% and 44.7%. Crop losses due to specific diseases are also reported to the tune of 30%-40%. Cocoon crop is also affected due to Uzi fly, Exorista bombycis (Louis) infestation. Extent of infestation in West Bengal and Karnataka is between 40%-75%. Silkworm crop protection has been ingenuously investigated in various dimensions and prophylactic measures were developed. Intervention of crop technologies with adequate extension support crop loss due to diseases, which declined from 35% to 14%. Formulation and recommendation of disinfectants and management of rearing with productive breeds/hybrids ensured crop stability and added income of seri farmers. Elaborate technologies have been discussed for successful cocoon crop.

Incidence of diseases and pests is a serious concern in silk production due to prevailing tropical condition. Annual crop loss due to diseases during rearing varies between 15% and 20% in national level and in West Bengal it ranges between 35.7% and 44.7%. Crop losses due to specific diseases are also reported to the tune of 30%-40%. Cocoon crop is also affected due to Uzi fly, Exorista bombycis (Louis) infestation. Extent of infestation in West Bengal and Karnataka is between 40%-75%. Silkworm crop protection has been ingenuously investigated in various dimensions and prophylactic measures were developed. Intervention of crop technologies with adequate extension support crop loss due to diseases, which declined from 35% to 14%. Formulation and recommendation of disinfectants and management of rearing with productive breeds/hybrids ensured crop stability and added income of seri farmers. Elaborate technologies have been discussed for successful cocoon crop.
