| 摘 要： | 利用光学显微镜、扫描电镜和透射电镜对韭菜迟眼蕈蚊成虫触角感受器的细微结构进行了观察研究。根据感受器外部特征和内部结构,将触角感受器分5种类型,分别是毛形感器、锥形感器Ⅰ、锥形感器Ⅱ、机械感觉毛Ⅰ、机械感觉毛Ⅱ。这5种类型感受器分布在触角不同部位,毛形感器、锥形感器Ⅰ、锥形感器Ⅱ分布于鞭节,而机械感觉毛Ⅰ、机械感觉毛Ⅱ主要分布在柄节和梗节。对雌雄虫触角各种感受器数量比较发现,雄成虫毛形感器数量极显著(P<0.01)多于雌虫的,而雌虫锥形感器Ⅰ的数量极显著(P<0.01)多于雄虫的。

| Abstract: | The fine structure of antennal sensilla in adult Bradysia odoriphaga Yang et Zhang were investigated by light and electron microscopy(both scanning and transmission).Based on their fine structures,sensilla on adult antennae were divided into five types:sensilla trichodea,sensilla basiconicaⅠ,sensilla basiconicaⅡ,mechanoreceptorsⅠand mechanoreceptorsⅡ.There were differences for the distribution of these sensilla on antennae sensilla trichodea,sensilla basiconicaⅠand sensilla basiconicaⅡlocated on the flagellum,while mechanoreceptorsⅠand mechanoreceptorsⅡmainly on the scape and pedicel.According to the number of the sensilla,there were more sensilla trichodea on males than on females(P<0.01) and there were more sensilla basiconicaⅠon females than on males(P<0.01). |
