柞蚕脓病主要是核型多角体病一种,养蚕群众称谓“老虎病”或“黄烂病”,过去我省柞蚕生产中发病率30%左右。对该病的防治研究,曾经从多方面进行过探索,第一,用福尔马林死毒疫苗接种,由于柞蚕本身免疫力很低,多次测定保护指数不超过0.5,故无应用价值。第二,药物治疗。我们先后筛选了百余种抗病毒药剂,仅有几种药剂,如肽丁胺等,有一定的治疗效果,添食低量病毒,治愈率只有30%左右,也无应用价值。第三,研究病原及传染规律并采用消毒防病措施,取得了明显 Tussah pus is mainly a nuclear polyhedrosis, sericulture masses called “tiger disease” or “yellow disease”, in the past the incidence of tussah in our province about 30%. The prevention and treatment of the disease, has been explored from many aspects, first, with formalin vaccination, as tussah itself immunity is very low, many times to determine the protection index does not exceed 0.5, so no application value. Second, medical treatment. We have screened hundreds of antiviral agents, only a few agents, such as peptide butylamine, have a certain therapeutic effect, add a small amount of virus, the cure rate is only about 30%, there is no application value. Third, the study of pathogens and the law of infection and the use of disinfection and disease prevention measures have been made clear
