摘要: 雄性双翅目昆虫,包括家蝇Musca domestica、丽蝇Calliphora erythrocephala、华虻Tabanus mandarinus和憎黄虻Atylotus miser Szilady,其复眼性特化光感受器中央小网膜细胞R7的分布从背区扩展到腹区。在雄性家蝇、华虻和憎黄虻复眼中,性特化光感受器中央小网膜细胞R7的感杆延伸到基底膜,并同中央小网膜细胞R8的感杆并列排列。但在雄性丽蝇复眼中,性特化光感受器中央小网膜细胞R7的感杆不延伸到基底膜。在雌性双翅目昆虫复眼中,性特化光感受器中央小网膜细胞R7仅仅分布在复眼的腹区,其数量比中央小网膜细胞R8少得多。

Abstract: The sex-specific photoreceptor central retinula cells R7 extend to ventral region from the dorsal region in male dipterous insects, including Musca domestica, Calliphora erythrocephala, Tabanus mandarinus and Atylotus miser Szilady. The rhabdom of the sex-specific central retinula cell R7 extends to the basement membrane and keeps abreast of the rhabdom of the central retinula cell R8 in male Musca domestica, Tabanus mandarinus and Atylotus miser Szilady, but does not extend to the basement membrane in male Calliphora erythrocephala. The sexspecific central retinula cells in the compound eye of the female dipteran are only distributed in the ventral region of the compound eye and are less numerous than central retinula cells R8 in the same region
