| 摘 要： | 对亚洲玉米螟成虫触角的外部形态结构在扫描电镜下作了观察.触角由柄节、梗节和62—67个鞭节组成,触角背面被鳞片覆盖,绝大部分触角感器位于触角的腹面和侧面.所有鞭节的表皮上都有连续的网纹结构,但在柄节和梗节的表皮上则无.在雌雄蛾的触角上都可以找到以下七种感器,即栓锥感器、腔锥感器、锥形感器(即B?hm氏鬃毛)、刺形感器、耳形惑器、鳞形感器和毛形感器.毛形感器数目最多,并根据其形状和表面细微结构分为两种类型:A型和B型.除锥形感器外,所有的感器都分布在触角鞭节的网纹区上.对此昆虫的触角两性差异进行了详细的讨论.

| Abstract: | The external morphological structures of the antennae of Ostrina jurnacalis were observed with a scanning electromicroscope. The antennae of the make and female moths consist of scape, pedicel and 62-67 flagellar segments. The dorsal aspect of the antennae of both sexes is cove-red by 2 rows of scales per segment. The reticuiation of the cuticle of the flagellar segments ex-tend around segmental cylinders under the scales, but the cuticie of the scape and pedicel lacks the reticuiation characteristic of those segments. Most of the sensilla are localized on the ventrai side of the antennae. The sensilla found on the antennae of both male and female moths inclu-de sensilla styloconka, sonsilla coeloconica, sensilla basiconica, sensilla chaetica,, sensilla auri-cillica,seusilla squamiformia and sonsilla trichodea. The sensilla trichodea are the most iabundani and can be subdivided into two distinct types (type A and type B) according to form and sur-face substructure. All sensilla, except sensilla basiconica, occur on the reticulated area of the antennae. Sexual dimorphisim of the antennae were discussed in detail. |
