利用赤眼蜂治虫是一项主要的生物防治方法。如何长期保存赤眼蜂的寄主卵乃是目前生产中一个急待解决的技术问题。除苏联有用液氮冷冻麦蛾卵的报导外。国外未见报导。我们根据家畜精液冷冻保存的技术和经验。于1983年开展了对赤眼蜂中间寄主卵(米蛾卵、松毛虫和柞蚕卵)冷冻保鲜试验。通过对甘油、二甲亚矾、蔗糖、聚乙烯吡 The use of Trichogramma is a major biological control method. How to preserve the host eggs of Trichogramma long-term is an urgent technical problem in production. In addition to the Soviet Union, the use of liquid nitrogen frozen moth eggs reported. No reports from abroad. We are based on the technology and experience of frozen storage of domesticated semen. In 1983 carried out on the Trichogramma host eggs (rice moth eggs, pine and tussah eggs) frozen preservation test. Through the glycerol, dimethyl alum, sucrose, polyvinylpyridine
