中文摘要：应用扫描电镜对麦蛾茧蜂Bracon hebetor Say的触角感器进行观察。结果表明：麦蛾茧蜂的触角上存在6种感器，分别为毛形感器，板形感器，刺形感器，鳞状感器，锥形乳头状感器和嗅孔。其中毛形感器和板形感器是主要感器，数量较大，分布较广。雌雄蜂的触角感器差异不明显。
英文摘要：Antennal ultrastructure of Bracon hebetor Say was observed with scanning electron microscope. It was found that six types of sensilla, including sensillum trichodeumⅠ,Ⅱ,Ⅲ, sensillum placodeum, sensillum chaeticum, sensillum squamiformium, sensillum basiconicum and foramen olfactorium, were found on the antenna of wasp. As the major sensilla, both sensillum trichodeum and sensillum placodeum were distributed widely on the antenna with larger amount. There was no significant difference between female and male antennal sensilla.
