柞蚕寄生线虫是柞蚕主要敌害之一。在辽宁、吉林、山东、河南、贵州等省柞蚕区均有发生与为害,但以辽宁分布最广,为害最重。全省约有两万把(140万亩)蚕受害。东沟、岫岩、凤城、宽甸、庄河、盖县、丹东郊区等十余个县区,每年都有程度不同的发生。一般受害率50～60％,重者80～90％,甚至粒茧不收。致使大面积蚕场被迫停放,并有逐年蔓延的趋势,严重威胁柞蚕生产的发展。在毛主席革命路线指引下,我们本着科研为无产阶级政治服务,为工农兵服务,为发展柞蚕生产贡献
Tussah parasitic nematodes is one of the main enemy of tussah. In Liaoning, Jilin, Shandong, Henan, Guizhou and other provinces tussah have occurred and damage, but the most widely distributed in Liaoning, the most serious damage.
