| 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。 |

| Abstract: |
| 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.vitessoides55.74%. The results of this study indicate that T. evanesceus is a potential natural enemy of H. vitessoides. |
