苹果榕传粉小蜂雌性触角感器及其生态学意义

利用扫描电子显微镜对苹果榕传粉小蜂Ceratosolen sp.雌性触角感器进行观察。结果显示:苹果榕传粉小蜂雌性触角呈膝形,分布着7类13种类型的感器,包括毛型感器、多孔的板型感器、锥型感器(2种类型)、栓锥型乳突状感器、刺型感器(4种类型)、腔锥型感器(3种类型)和一种专一性的角锥型感器。对各感器的形态、数量、分布进行描述,并结合感器的选择性染色(Ag+染色)、传粉小蜂行为及其榕/蜂互惠共生系统,对不同类型感器的功能和生态学意义进行探讨。

Antennal sensilla of female fig pollinator Ceratosolen sp. and its ecological implication

The antennal sensilla of female parasitoid, Ceratosolen sp. (Hytnenoptera: Agaonidae) , were observed with scanning election microscopy (SEM). The antenna was geniculate in shape, and consisted of three basal segments. Thirteen types of sensilla were distinguished, including sensilla trichodea (1 type), multiporous placoid sensilla (1 type), basiconic sensilla (2 types), basiconic capitate peg sensilla, chaetica sensilla (4 types), coeloconic sensilla (3 types) and one specialized sensillum regarded as sensillum obscunun. The morphology, abundance, distribution of the sensilla was recorded. Their putative functions were analyzed based on selected staining results and wasp behavior observed in the field. Furthermore, the ecological significance of the sensilla was also discussed in relation to the specific relationship between the fig/wasp mutualism.
