结果发现:(1)其复眼呈半球形,位于头部两侧,略成"八"字形排列,单个复眼约由3600个小眼组成,最前和最后小眼之间的夹角约为180°,最上和最下小眼之间的夹角约200°;(2)小眼主要由角膜、晶锥和6~8个小网膜细胞、基膜组成,外围环绕有2个初级虹膜色素细胞和6个次级虹膜色素细胞,基膜处有色素颗粒分布;(3)暗适应时,晶锥开裂程度较大,远端5~7个网膜细胞核向远端移动,与晶锥近端相接或接近,次级虹膜色素颗粒亦向远端移动包围晶锥;明适应时,晶锥开裂程度小或闭合,远端网膜细胞核向近端移动,透明带显现,大部分次级虹膜色素颗粒亦向近端移动分布在小网膜细胞柱周围,包被透明带;(4)在相同的明、暗适应下,雌、雄成虫复眼的显微结构无明显差异。
