Various climate types and ecological environment in China have led to high species persity and genetic persity of lac insects, which provide good condition for lac production.
紫胶虫具有重大的经济价值，我国紫胶虫物种和遗传资源丰富，气候类型和生态环境多样，为发展紫胶生产提供了良好的条件。
Comprehensive methods and formulas of lac insect evaluation were proposed in this paper based on such indexes from lac insect cultivation and production.
本文在紫胶虫培育和生产中的评价指标基础上 ,建立综合评价方法及评价公式 :(1)种胶的判断公式是E =e×p× (1-m)× (1-s) ;(2 )生产判断公式是I =(Nt+ 1) /Nt=∏(si)·p♀·F ;(3)寄主植物的判断公式是E =p× (1-m)× (1-s) ×d。
