| 中文摘要: |
| 使用扫描电镜技术系统观察并描述了柚木野螟 Eutectona machaeralis Walker幼虫触角及其口器上的化学感受器。观察结果如下:柚木野螟幼虫的头式为下口式,咀嚼式口器,头上有触角、单眼、感觉刚毛、上唇、下唇、上颚、下颚、下颚须、下唇须、吐丝器等。幼虫头部下方有1对触角,触角上有6种感受器,分别是毛形感器、短毛感器、锥形感器、刺形感器、栓锥感器和小锥形感器。口器附肢下颚须上有栓锥感器,下唇须上有刺形感器。在吐丝器前方有1对锥形感器。 |
| 英文摘要: |
| In this study,the scanning electron microscopy (SEM) was used to observe and describe the chemoreceptors on the antennae and mouthparts of Eutectona machaeralis Walker larvae. The observation results were as followed:1) The head structure type of the larvae was hypognathous. 2) There were a pair of antennae on the head of the larvae and six kinds of chemoreceptors on the antennae, namely sensillum trichodea, short sensillum trichodea, sensillum basiconica, sensillum styloconica, sensillum chaeticum and small sensillum basiconica. 3) Three sensilla styloconica were observed on the maxilla and maxillary palpus;one sensillum chaeticum was found on labial palpus, and one sensillum chaeticum was found on the front of each side of fusula. |
