摘　　要：应用扫描电镜技术对竹织叶野螟雌雄蛾触角感器进行研究。结果表明,竹织叶野螟触角呈丝状,由柄节、梗节和分为74~80个亚节的鞭节组成。触角上存在7种感器,其中毛形感器数量最多,其次是耳形感器和腔锥形感器;毛形感器、刺形感器、腔锥形感器Ⅰ型、耳形感器Ⅰ型、栓锥形感器、鳞形感器和Bhm氏感器为雌雄蛾所共有,腔锥形感器Ⅱ型、耳形感器Ⅱ型仅分布于雄蛾触角上,且腔锥形感器Ⅱ型为螟蛾科首次发现。对竹织叶野螟触角各感器的形态、分布以及雌雄间触角感器形态和数量差异进行描述,此外就竹织叶野螟与其相近种昆虫触角感器间的差异进行讨论。Algedomia coclesalis is one of the serious pest moths on bamboo. Antennal sensilla of A. coclesalis were observed with a scanning electron microscopy （ SEM）. The results showed that the antennae of both adult female and male were filamentous and consisted of scape, pedicel and flagellar segments. The flagellar segment was consisted of 74 - 80 subsegments. Seven types of sensilla were found on the antennae of both female and male, i. e. , trichodea（ I and Ⅱ ） , cheatica（ I and Ⅱ） , coeloconica（ I and Ⅱ ） , auricillica（ I and Ⅱ ） , styloconica（ I and Ⅱ ） , squamiformia, and Bohm bristles（ I and Ⅱ ）. The trichodea was the most abundant, followed by coeloconica and auricillica. The morphology of sensilla was different between male and female. Coeloconica Ⅱ and auriculatea II are found only on male, the other types are observed on both genders, although the numb^er of trichodea in male was larger than in female. The shape, distribution, and difference of sensilla between male and female were described. Sensilla difference between A. coclesalis and other moths was discussed.
