摘　　要：利用扫描电镜对迟眼蕈蚊触角的形态和感器进行了观察。结果表明:迟眼蕈蚊触角呈丝状,由柄节、梗节和鞭节组成。整个触角长度为0.83~1.14 mm,鞭节长度为0.99~1.00 mm,分为14亚节。触角上的感器有9种,即毛形感器、刺形感器、锥形感器、耳形感器、腔锥形感器、缘感器、柱形感器、乳状感器、Bohm式鬃毛,不同感器在触角上的分布不同。其中,毛形感器的种类和数量在触角感器中居首位。Antennal morphology and sensilla of Bradysia sp.were observed under scanning electron microsco-py.The results show that the antenna is made up of three parts:scape,pedicelland a 14 segmented flagella.The length of the total antenna is 0.83-1.14 mm,while the entire length of flagella is 0.99-1.00 mm.Nine types of sensillum were observed on the antennae;sensilla trichodea,sensilla chaetica,sensilla basiconicum,sensilla auricil-lica,sensillum coeloconica,sensilla margin,sensilla cylindric,sensilla mammilliformia,bohm bristles.The type and quantity of the sensilla trichodea are the most abundant among the nine sensillum .
