摘　　要：为了掌握核桃长足象触角上的感器类型、数量和分布规律,利用扫描电子显微镜对核桃长足象雄性成虫触角上的感器进行观察。结果表明:核桃长足象触角上分布9种感受器类型,分别为毛形感器、腔锥感器、刺形感器、锥形感器、端指形感器、鳞形感器、腔形感器、棒形感器和叉形感器;感器的类型和数量在柄节、梗节和鞭节上的分布规律有明显差异,柄节的感器类型、数量较少,鞭节的第6、7鞭亚节上的感器类型和数量最多,说明这2个亚节是触角感受能力最强的部位。In order to know sensilla type,number and distribution on the antennae of Alcidodes juglans,the sensilla on the antennae of male adults of Alcidodes juglans was observed by scanning electron microscope.The results showed that nine types of antennal sensilla were identified,including sensilla trichoid,sensilla coeloconica,sensilla chiaetica,sensella basiconca,sensella finger-like and sensilla squamiformia,sensilla cavity,sensilla rod-like,sensilla furcatea.There were obvious differences in the distribution,type and number of sensilla between scape,pedicel and flagellum.The type and number of sensilla on the scape were less,and the type and number of sensilla on the 6 th and 7 th flagellum were the most,which suggested that the 6 th and 7 th flagellum are the most strongest parts of antennal receptivity.
