摘　　要：夜蛾黑卵蜂Telenomus remus Nixon是鳞翅目夜蛾科害虫卵期的重要寄生性天敌.通过扫描电镜对夜蛾黑卵蜂雌蜂触角感器进行观察,共发现9种类型的感器,分别为锥形感器、毛形感器、栓锥感器、钟形感器、毛状弯曲形感器、具沟端弯感器、端孔坛形感器、芽孢形感器和刺形感器.其中锥形感器具有3种形态,锥形感器Ⅰ分布于柄节与头部及梗节连接处,锥形感器Ⅱ常见于端孔坛形感器周围,锥形感器Ⅲ分布于鞭节,数量较少.毛形感器数量较多,在柄节、梗节及鞭节均有分布.其他7种类型的感器则主要集中于触角的第8～11节.Telenomus remus Nixon （ Hymenoptera ： Scelionidae） is an egg parasitoid of Noctuidae insects. The antennal sensory sensilla of female parasitoid were observed with scanning electron microscopy. Nine distinct types of sense receptors were observed, including sensillum basiconica, sensillum triehodea, sen- sillum trichodea curvata, sensillum styloconicum, sensillum campaniformium, fluted bent-tipped sensil- lure, pore-tipped ampullaceous sensillum, sensillum gemmiformium and sensillum chaeticum. Three forms of sensillum basiconica （SB） were found. SB I were distributed at the end parts of scape that link the head and pedicel; SB m were only found at the flagellum, and SB 1 were always accompanied with the pore-tipped ampullaceous sensillum. Sensillum trichodea were distributed widely on the antenna with larger amount. However, the other seven sensilla were mainly distributed at the eighth to the eleventh fragments of antenna.
