三种紫胶虫胶质比较研究李金元，赵玉兰，李义龙，黄维垣关键词紫胶虫，紫胶树脂，原胶质量我国生产上主要放养三个紫胶虫种［１］：紫胶虫〔Ｋｅｒｒｉａｌａｃｃａ（Ｋｅｒｒ）〕、信德紫胶虫〔ｋｅｒｒｉａｓｉｎｄｉｃａ（Ｍａｈｄ．）〕和中国紫胶虫〔Ｋｅｒｒｉａｃ...
Tests have been conducted for the gradation of the raw lac produced by threespecies of lac
insects along with the contents of hard and soft resins respectively. The resultshave shown
that the content of soft resin excreted by K. chinensis Mahd.in summer genera-tion is lower
than those by K. sindica Mahd.and No. 4 lac insect,K. lacca Kerr. by 1%～2%。In winter
generation it is comparatively higher and the content of yellow pigment isricher in both
generations especially in summer one. It is 1～4 times that of each of the lattertwo. The soft
resin content of the latter two is higher in both generations though somewhathigher in winter
period. On the contrary,the yellow pigment content in the raw lac yieldedby K. chinensis
Mahd.is lower both in summer and winter generation.
