dorsalis雌成虫外周感受器的种类、分布和形态结构，采用扫描电子显微镜观察触角（鞭节）、下颚须、喙、足、翅及产卵器上的感受器种类和形状。结果显示：橘小实蝇雌成虫6种器官上主要分布有5种类型感受器，分别为微毛型感受器、毛型感受器、锥形感受器、腔锥形感受器和刺型感受器。微毛型感受器分布于触角、下颚须、喙、足和翅上，其中足上有3种亚型（Ⅰ～Ⅲ型），翅上微毛型感受器的长度长于触角、下颚须、喙上的微毛型感受器。毛型感受器分布于触角、喙和产卵器上，触角上的毛型感受器形状明显区别于喙和产卵器上的毛型感受器。锥形感受器分布于触角、下颚须和喙上，其中触角和喙上分别有2种（Ⅰ型和Ⅱ型）和3种亚型（Ⅰ～Ⅲ型）；仅触角和下颚须上的锥形感受器表面分布有小孔。腔锥形感受器分布于触角和产卵器上，产卵器上有2种亚型（Ⅰ型和Ⅱ型），其中Ⅰ型呈对称分布。刺型感受器分布于下颚须、喙、足、翅和产卵器上，形状相似，足上有3种亚型（Ⅰ～Ⅲ型）。表明橘小实蝇不同外部器官上的感受器在分布、种类和形态上存在差异，暗示这些感受器可能在不同的生物学功能中发挥作用。

dorsalis, scanning electron microscopy was used to examine sensilla on the antennae(funiculus), maxillary palps, proboscis, legs, wings, and ovipositor. The results revealed that five types of sensilla were mainly distributed across six organs: microtrichia, sensilla trichoid, sensilla basiconica, sensilla coeloconica, and sensilla chaetica. Microtrichia were distributed on the antennae, maxillary palps, proboscis, legs, and wings. Notably, three subtypes(Ⅰ-Ⅲ) were observed on the legs, and those on the wings were longer than those on the antennae, maxillary palps, and proboscis. Sensilla trichoid were distributed on the antennae, proboscis, and ovipositor, with distinct morphological differences between those on the antennae and those on the other two organs. Sensilla basiconica were found on the antennae, maxillary palps, and proboscis. Two subtypes(Ⅰ and Ⅱ) were present on the antennae and three subtypes(Ⅰ-Ⅲ) on the proboscis. Pores were observed on the surface of sensilla basiconica on the antennae and maxillary palps, but not on the proboscis. Sensilla coeloconica were located on the antennae and ovipositor, with two subtypes(Ⅰ and Ⅱ) on the ovipositor, among which subtype Ⅰ exhibited a symmetrical distribution. Sensilla chaetica were distributed on the maxillary palps, proboscis, legs, wings, and ovipositor, displaying similar morphology across organs, with three subtypes(Ⅰ-Ⅲ) identified on the legs. These results indicate that sensilla on different external organs of B. dorsalis differ in their distribution, type, and morphology, suggesting that these sensilla may perform distinct biological functions. keywords:Bactrocera dorsalis  peripheral sensilla  scanning electron microscopy  sensilla type and function View Full Text  View/Add Comment  Download reader
