茶毒蛾黑卵蜂是茶毒蛾卵期的优势寄生蜂,能将茶毒蛾消灭在幼虫发生为害之前,识主利它素对它的寄生活动起着重要的作用。试验结果表明,茶毒蛾黑卵蜂的识主利它素存在于茶毒蛾的卵块和卵粒上,能被蒸馏水、70%甲醇或乙醇溶液等极性溶剂所抽提,其粗抽提物可诱发80%以上的雌蜂表现出触角敲打和产卵管刺探行为,但不能被己烷等非极性溶剂所抽提。识主利它素在室温条件下较稳定,但是高温加热(100℃)处理1小时可使之丧失部分活性。识主利它素的应用不仅可增强黑卵蜂的搜索活动,缩短寄生时间,提高对寄主卵的寄生效能,还能引诱其寄生原来不寄生的非寄主卵,有利于茶毒蛾黑卵蜂的室内大量饲养和繁殖。
Tea poisonous moth, black eggs, is the dominant parasitic wasps in the egg stage of the tea poisonous moth. It can eliminate the tea molt. Before the larvae are killed, they know that prednisolone plays an important role in its parasitism. The experimental results show that the knowledge of the dominant neprilysin of the black oyster from the tea poisonous moth is found in the eggs and eggs of the tea poisonous moth and can be extracted by polar solvents such as distilled water and 70% methanol or ethanol solution. The crude extracts More than 80% of the female bees evoked antennae and spawning behavior but could not be extracted by non-polar solvents such as hexane. Sidulacetin is more stable at room temperature, but high temperature heating (100 ° C) for 1 hour can make it lose some activity. The application of sida albitos not only enhances the searching activity of black oyster, shortens the time of parasitism, improves the parasitism effect on the host egg, but also lures the non-host egg which does not parasitize the parasite, Indoor large breeding and breeding.
