摘要
本试验从病毒的致病力,蚕的感染抵抗性,蚕饲育技术三方面对家蚕核型多角体病发生较多的原因进行了研究与分析。认为多发的根本原因在于蚕室蚕具消毒不彻底、忽视地面消毒和地面用药的不当。该病之所以在中秋蚕期多发一与病毒的数量积累有关,二与所用蚕品种在中秋蚕期对该病的感染抵抗性降低有关。
The causes of Naclear Polyhydrosis Disease (NPD) were studied with the effect of virus, the infecteel resistance of silkworms, the breeding process of silkworms.
The frequent occurance of the disease was mainly caused by incomplete sterlization of the house—neglector the ground sterilization and improper application of stenlants. The occarrauce of NPD in mid autumn coas related with the accumulation of virus and the significant decrease in the resistance of the silkwormn varieties used in the province.
