【摘要】 通过盐析、柱层析和分子筛层析，从松毛虫雌蛾附腺中分离到一种ＳＰ－Ｉ组份，经生化方法检测鉴定，此组份是一种糖蛋白，分子量为１．３５×１０５，等电点为４．２，蛋白质含量９２％，糖含量８％．它能引诱松毛虫黑卵蜂和松茸毒蛾黑卵蜂在非天然寄主上的产卵检查、刺探行为，是一种黑卵蜂寄主识别利它素．更多还原

【Abstract】 A compound named SP Ⅰwas isolated from the extract of the female Dendrolimus punctants and partially putified by (NH 4) 2SO 4 Salting out,CM C cation exchange column chromatography,Sephadex G 200 gel filtration.It was obtained clearly in one band in SDS PAGE.The molecular weight of the compound was 1.35×10 5;it was a acidic glucoprotein(pI=4.2),and contained 92% protein,8% carbohydrate. The bioassay results revealed that it could induced Telenomus dendrolimusi and T.dasychiri Chen et Wu to examine and to probe the artiticial host egg coated with SP Ⅰ,the host recognition kairomone.更多还原
