一、前言家蚕病毒病是我国当前蚕业生产上为害十分严重的一种蚕病,全国各地均有发生,尤其在夏秋蚕时期,蔓延更加剧烈。目前对病原虽已初步探明,但传染規律、誘发因素等方面还不够清楚,因此尚无絕对控制其发生的有效防治方法。虽然如此,消毒还是防治蚕病的首要关鍵。目前預防蚕病的消毒药剂各有其优缺点:漂白粉消毒力虽强,但有效氯易于消失;福尔馬林单独使用,其消毒力对胃腸型脓病多角体消毒效果很差,消毒蚕室又必須密閉,遇低温会产生聚甲醛成白色沉淀,降低其消毒力等等。近年来中外学者对蚕病病原体的消毒药剂方面做了一些研 I. Introduction The silkworm virus disease is a kind of silkworm disease that is seriously harmed in the production of sericulture in our country and has occurred all over the country. Especially in the summer and autumn silkworms, the spread is even more severe. Although the pathogen has been initially proved, but the infection rules, triggers and other aspects is not clear enough, there is no absolute control of its occurrence and effective prevention and treatment methods. Nevertheless, disinfection is the primary key to prevention and treatment of silkworm disease. At present, the disinfectants for preventing silkworm disease have their own advantages and disadvantages: although the disinfectant power of bleaching powder is strong, the available chlorine tends to disappear; while the formalin is used alone, the sterilizing effect of the sterilizing agent on the polyhedron of gastrointestinal type of pus is very poor, Must be sealed, in case of low temperature will produce poly-formaldehyde into white precipitate, reducing its disinfection and so on. In recent years, Chinese and foreign scholars have done some research on the disinfectants of silkworm pathogens
