柞蚕放养在野外,经常受到各种不良条件和病虫害的侵袭而影响产量。柞蚕寄生线虫就是我省柞蚕重要敌害之一。此外,在吉林、山东、河南、贵州等省部分柞蚕区,都有发生和为害。据不完全统计,辽宁有近三万把(210万亩)柞蚕场有线虫发生和危害,其中最严重的也有一万余把。在有效防治之前,蚕儿受害率一般为50～60%,重者可达90%以上,故有些蚕场被迫停止养蚕。

Tussah stocking in the wild, often affected by various adverse conditions and the invasion of pests and diseases affect the yield. Tussah parasitic nematodes is one of the main predators in our province tussah. In addition, parts of tussah areas in Jilin, Shandong, Henan and Guizhou provinces have occurred and been harmed. According to incomplete statistics, there are nearly 30,000 (2.1 million mu) tussah farms in Liaoning that have nematode occurrence and harm, of which the worst is about 10,000. Prior to the effective prevention and treatment, the damage rate of Caner children is generally 50 to 60%, and the severe case up to 90% or more, so some silkworm farms were forced to stop sericulture.
