2、代,以蛹滞育越冬;幼虫食性杂,喜食榛(Corylusheterophylla)、旱柳(Salixmatsu—dana)、胡桃楸(Juglansmandshurica)等的树叶;幼虫期4眠5个龄期,少见5眠6个龄期,全龄经过27—41d,因取食不同树种的树叶其龄期经过有差异。对野生柳蚕的人工试养结果表明:l9~23oC、RH75%~85%为暖卵最适温度和湿度;在室内自然温度(19~26℃)、湿度(RH60%~75%)和光照条件下,以榛叶饲养的幼虫全龄发育历期最短(34.6d),收蚁结茧率可达45%,显著高于野外人工饲养;饲养过程中须注意对软化病、白僵病以及寄生蝇和寄生蜂等病虫害的防控。关键词
