摘要:

利用扫描电镜对宽颊纹潜叶蜂Kaliofenusa genata雌蜂触角的形态特征、感觉器的类型及分布特点进行了观察.结果表明,宽颊纹潜叶蜂雌蜂触角呈丝状,由基节、柄节、梗节、鞭节组成.其中,鞭节由7鞭小节组成.触角上着生有6种感觉器,分别是毛形感觉器(Ⅰ型、Ⅱ型、Ⅲ型和IV型)、锥形感觉器(Ⅰ型和Ⅱ型)、刺形感觉器、锥形乳突状感觉器、芽形感觉器和Bhm氏鬃毛.其中,毛形感觉器I广泛分布在除基节以外的其他各节上;毛形感觉器II和III主要分布在柄节和梗节上;毛形感觉器IV主要分布在鞭小节的端部.刺形感觉器、芽形感觉器以及锥形感觉器I主要分布在鞭节的末端鞭小节上.腔锥形乳突状感觉器和锥形感器II主要分布在除第1鞭小节以外的其他鞭小节上.Bhm氏鬃毛仅分布在基节中部.结合相关研究报道,对宽颊纹潜叶蜂雌蜂触角各种感觉器可能的功能进行了探讨.

We observed the morphological characteristics, types and distributions of antenna sensilla of K. genata with scanning electron microscopy in this study. The results showed that the antenna of female adult K. genata was filiform, and composed of eoxa, scape, pedicle and flagellum. The female adult flagellum had seven segments. Six types of antennal sensilla were identified in antenna, including sensilla trichodea, sensilla basiconic, sensilla chaetica, sensilla coeloconiea, sensilla gem- miformium and B6hm bristles. Sensilla trichodea I was found verticulate in antennae segments except coxa, while sensilla tri- chodea Ⅱ and Ⅲ were detected mainly distribution in seapes and pedieles and sensilla trichodea IV only in distal end of flagellum segments. Sensilla chaetiea, sensilla gemmiformium and sensilla basiconic I were presented the distal segments of flagellum. Sensilla coeloconica and sensilla basiconic II were found mainly on the flagella except the first flagella segments. B6hm bristles located on the coxa. The especially function of sensilla need to be further explored in future.
