Abstract: We compared and analyzed the ultrastructure, type, distribution and number of antennal sensilla in morphs of the aphid Schlechtendalia chinensis (Bell), using scanning electron microscopy. The results showed that S.chinensis has four types of antennal sensilla: Trichoid sensilla, primary rhinaria, sensory projections and secondary rhinaria, all of which varied in their distribution and number on the antenna in the different morphs. Trichoid sensilla could be divided into I and II types, and they distributed on all morphs of S.chinensis’antenna. Primary rhinaria were mainly observed on the antenna of fundatrices, apterous fundatrigeniae, nymphal alate fundatrigeniae, males and females. There are two types of PrⅠ and PrⅡ, occurring on the last and penultimate segment, respectively. But there was only PrⅠon the antenna of nymphal alate fundatrigeniae. The sensory projection was only located on the third to fifth segments of the antenna of nymphal alate fundatrigeniae. Secondary rhinaria were only located on the third to fifth segments of the antenna of alate fundatrigeniae and alate sexuparae. And they accounted for approximately two-thirds of the antennal surface. We suggest that these differences are related to the habitat of the particular morph (e.g. internal or external to the gall), its main form of behavior (e.g. feeding, mate selection) and whether the morph is winged (e.g. host or migration).

摘要：本研究利用扫描电镜对角倍蚜各蚜型触角感器的超微结构、类型、分布和数量进行了比较分析。结果表明，角倍蚜的触角上着生4种类型的感器：毛形感器、原生感觉圈、感觉突及次生感觉圈，它们在各蚜型触角上的分布和数量各不相同。其中，毛形感器有TypeⅠ和TypeⅡ两种类型，各蚜型触角上均有分布；原生感觉圈主要分布于干母、无翅干雌、第3代有翅干雌若蚜以及性蚜的触角上，有两种类型：PrⅠ和PrⅡ，分别位于触角的末节和倒数第2节，其中，第3代有翅干雌若蚜的触角上仅存在PrⅠ，无PrⅡ；感觉突仅出现于第3代有翅干雌若蚜触角的第3～5节；次生感觉圈仅存在于有翅型春迁蚜和秋迁蚜触角的第3～5节，其面积约占触角鞭节面积的2/3。因此，推测各蚜型触角感器的差异可能与蚜虫的生境(瘿内或瘿外)、行为(如取食、交配)以及翅的有无(如寄主选择、迁飞等)有关。
