摘　　要：采取农村面上饲养调查和定点饲养调查两种方式,对现行两个家蚕抗性品种"苏豪×钟晔(抗)"和"华康3号"在如皋市秋季相对恶劣环境条件下进行了生产对比试验。结果表明,"苏豪×钟晔(抗)"蚕体大、茧型大,全茧量大于"华康3号";"华康3号"抗血液型脓病的优势较为明显,死笼率、发病率均低于"苏豪×钟晔(抗)",虫蛹率高于"苏豪×钟晔(抗)"。同时通过对两个调查点养蚕农户的用药习惯进行分析,认为只有加强饲养管理,规范养蚕用药,将"预防为主,防治结合"的措施贯穿到养蚕全过程,才能更好的发挥抗性蚕品种的优良特性。The comparative production tests on two disease-resistant silkworm varieties,“Suhao×Zhongye(Kang)”and“Huakang No.3”,were carried out by means of general rearing performance survey and on site investigation on fixedrearing farmers under relatively harsh environmental conditions in autumn in Rugao City.The results showed that“Suhao×Zhongye(resistant)”had bigger larval body,larger cocoon shape,and higher cocoon weight than that of“Huakang No.3”;meanwhile,“Huakang No.3”had stronger resistant ability to Nuclear Polyhedrosis,lower rate of dead worm cocoon,lower incidence of diseases and higher survival rate of larval-pupae than that of“Suhao×Zhongye(resistant)”.It come to the conclusion through the analysis on application habits of disease control drugs by silkworm rearing farmers in the two fixed-survey points that the disease resistant characteristics of silkworm varieties can show better performance only by strengthening the rearing management,standardizing the drug application during larval stage,and running through the whole process of cocoon production with the basic idea of“prevention in the first place and integrating prevention with control”.
