Observations of Antennal Sensilla of the Male Black Cutworm Moth with Scanning Electron Microscope

利用扫描电镜观察了小地老虎雄蛾触角感受器的种类、形态和分布。结果表明，小地老虎雄蛾触角为双栉状（端半部为丝状），由1节柄节、1节梗节和82～92节鞭节组成。在触角上分布有毛形感器、刺形感器、鳞形感器、腔锥感器、腔形感器、耳形感器、B6hm’s氏鬃毛7种感受器，其中毛形感器数量最多。

Morphology of antennal sensilla of male black cutworm moth is observed with scanning electron microscope. The results show that antenna of male black cutworm moth takes on a shape of two combs, and is made up of one scape, one pedicel and 82 -92 segments. There are seven types of sensilla on the male black cutworm moth＇s antenna, including sensillure trichodea, sensillum chaetieum, sensilla squamiformia, sensillum coeloeonicum, sensillum coelonica, sensillum auricillica and Bohm＇s bristles. The sensillum trichodea are the most numerous.
