摘要
从马尾松毛虫Dendrolimus punctatus新发生区采集虫源,在自然温湿度和光照条件下,借鉴家蚕的人工饲养经验和技术,采取卵面、松针、饲养室和饲养用具等的消毒措施,提高了室内饲养松毛虫幼虫的存活率和茧蛹的羽化率。马尾松毛虫在室内的规模化人工饲养取得了初步成功,顺利完成从卵到卵的生活世代,经过消毒的卵孵化率为91.4%,室内饲养幼虫的存活率达到92.54%,茧蛹的羽化率达88.4%,雌雄性比为1.08∶1。
Dendrolimus punctatus collected from the new occurrence places could complete its life cycle under the normal light, humidity and temperature when fed with pine needles in the laboratory after the sterilization of the surface of the eggs, rearing room and pine needles. The hatchability of the sterilized eggs was 91.4 %, the survival rate of the larvae reared in the lab was 92.54% and the emergence rate was 88.4 %. The ratio of females to males was 1.08 ： 1.
