【摘要】 采用组织切片法光镜下观察黑翅土白蚁Odontotermes formosanus(Shiraki)有翅成虫的复眼形态结构及光、暗适应条件下色素颗粒移动的规律。结果如下:(1)头正前方观,复眼外部形态略呈圆形。(2)有翅成虫复眼类型属于并列像眼,每只复眼约由360个小眼组成。(3)每个小眼是由1套屈光器(1个角膜和1个晶锥)、小网膜色素细胞、视杆和基细胞等几部分组成。小网膜色素细胞内均含有丰富的色素颗粒。(4)在光适应条件状态下,屈光器及视杆周围的色素颗粒主要分布在视杆部位的上侧,暗度适应条件状态时则较均匀地分布于视杆两侧上下;性别对色素颗粒分布无明显影响。更多还原

【Abstract】 The structure of compound eye of alates Odontotermes formosanus (Shiraki); and the characteristics of pigment granule movement under light and dark adaptation were investigated with optics microscope and histologyical slice. The results showed that compound eyes was hemisphere in shape of. The compound eyes of alates O. formosanus belonged to the type of apposition eyes. Each compound eye was composed of approximately 360 ommatidia. Each ommatidium consisted of a cornea, a cone, retinula cell, rhabdom and basal cell. Each retinula cell contained abundant pigment granules. In the light-adapted state, the distribution of the pigment granules were mainly around the top region of rhabdoms, however, the pigment granules distributed evenly around rhabdoms in the dark-adapted state. No difference was observed between male and female.更多还原
