| 中文摘要: |
| 利用扫描电子显微镜技术, 研究了云南锦斑蛾幼虫头部触角和口器上的感器。结果表明, 云南锦斑蛾幼虫头部呈椭球形。每根触角上具有1根毛形感器、1根刺形感器、5根锥形感器和1根栓锥形感器。上唇两侧各有6根刺形感器。内唇分布有6根刺形感器、4根内唇感器和2根指形感器。每个上颚表面具有2根刺形感器。下颚的感器主要分布在外颚叶和下颚须上, 每片外颚叶上具有3根刺形感器、3根锥形感器和2根栓锥形感器;每根下颚须上具有8根锥形感器。每根下唇须上具有1根锥形感器和1根栓锥形感器。因此, 锥形感器是云南锦斑蛾幼虫头部数量最多的感器, 可能是幼虫搜寻寄主的关键感器;不同类型的感器在长度上存在差异。 |

| Sensilla on antennae and mouthparts of Achelura yunnanensis were studied using the scanning electron microscopy technique. The results showed that its larval head was elliptical. One sensillum trichodeum (ST), one sensillum chaeticum (SC), five sensilla basiconica (SB) and one sensillum styloconicum (SS) were observed on each antenna. Six SC were found on each side of the labrum. Six SC, four epipharyngeal sensilla and two sensilla digitiformia were identified on the epipharynx. Each dentate mandible carried two SC. The sensilla on the maxilla were mainly distributed on the galea and maxillary palpus, in which each galea harbored three SC, three SB and two SS, and there were eight SB on each maxillary palpus. There were one SB and one SS on each labial palpus. In summary, SB was the most abundant sensilla on larval heads of A.yunnanensis, suggesting its key roles in host searching behaviors of larvae. In addition, various types of sensilla in length were different. |
