| 中文摘要: |
| 茶翅蝽 Halyomorpha halys(Stal)是水果和蔬菜生产中的重要害虫。为了寻找优势卵寄生蜂用于其生物防治，本文进行了相关的野外调查和室内试验。通过定期野外采集茶翅蝽卵块，培育、收集和鉴定寄生蜂，发现在自然环境中茶翅蝽卵粒的寄生率为56.29%，其中茶翅蝽沟卵蜂比例最高，占77.66%；其次是黄足沟卵蜂占20.44%。Y型嗅觉仪测定结果显示，茶翅蝽沟卵蜂和黄足沟卵蜂对茶翅蝽卵均具有明显的选择趋性。室内寄生能力试验结果表明，茶翅蝽沟卵蜂与黄足沟卵蜂单独作用的寄生率分别为94.06%和84.21%，与两种寄生蜂混合寄生茶翅蝽卵的寄生率91.65%均无显著性差异。两种寄生蜂混合寄生时，茶翅蝽沟卵蜂与黄足沟卵蜂的寄生比例分别为 58.95%和41.05%， 二者之间无显著差异。 |

| The brown marmorated stink bug, Halyomorpha halys (Stal)(Hemiptera: Pentatomidae) has a very broad host range and is a serious pest in fruit and vegetable production. In order to develop a biological control method to control this pest sustainably, we surveyed the parasitoids of H. halys by collecting its egg masses in the field at regular intervals. The results showed that the total parasitism of eggs is 56.29%, within, Trissolcus halyomorphae account for 77.66%, it is really a predominant parasitoid, and followed by T. flavipes, the parasitism is 20.44%. These two species were further studied by Y tube olfactometer to examine their olfactory responses to host eggs. Both parasitoids showed significant attraction responses to egg masses of H. halys. In addition, the parasitisms were tested in the laboratory by providing egg masses of H. halys to T. halyomorphae and T. flavipes alone or simultaneously. Results showed that the parasitism is 94.06% and 84.21% for T. halyomorphae and T. flavipes, respectively, there is no significant difference between them. The parasitism is 91.65% when mix two species, there is no significant difference with any one species alone, within,T. halyomorphae account for 58.95%, T. flavipes account for 41.05%, there is no significant difference between them. |
