摘　　要：广赤眼蜂Trichogramma evanesceus是农林生产中一种重要的天敌昆虫。研究明确了广赤眼蜂对黄野螟Heortia vitessoides卵的寄生习性及林地内对黄野螟卵的寄生率。广赤眼蜂寄生黄野螟的卵,每年可以繁殖17代,每代历期9~11天;实验室条件下平均出蜂率可达93.69%,林地内野外寄生卵块平均出蜂率87.16%。茂名地区白木香Aquilaria sinensis林内黄野螟卵平均寄生率可达55.74%。研究结果表明广赤眼蜂可以作为防控黄野螟的天敌资源加以利用。Trichogramma evanesceus is an important natural enemy in agriculture and forestry system. The parasitism habits of T. evanesceus in egg of Heortia vitessoides and the parasitization rate were determined. T.evanesceus can be bred 17 generations each year, and each generation lasts 9-11 days. The highest rate of output wasps was 93.69% in laboratory, and 87.16% in the field. The average parasitization rate in egg of H. vitessoides 55.74%. The results of this study indicate that T. evanesceus is a potential natural enemy of H. vitessoides.
