桃小食心虫复眼的外部形态及结构特征*

桃小食心虫(Carposina nipponensis Wals)蛾复眼的外部形态与棉铃虫(Heliothis armi-gera Hubner)蛾等较相似，但大小及结构明显不同，它的体长为o.54毫米，宽为o.50毫米，每只复眼大约有l500个小眼组成。 小眼密度为每平方毫米3301个。透明区占小眼总长的64%。网膜细胞多在远端膨大，细胞核也大都在此集中。本文对小眼及其周围分10个层次进行了描述和摄影。

MORPHOLOGY AND STRUCTURE OF THE COMPOUND EYE OF A MOTH, CARPOSINA NIPONENSIS WALS

The compound eye of the peach fruit moth, Carposina niponesis Wals. measures 0.54 mm by 0.50 mm in size and each of them contains about 1500 ommatidia arranged in a density about 330 per square millimeter. The clear zone is about 64% of the ommatidum. The re-tinula cell is enlarged at the distal end of the clear zone where the nucleus is located.The ommatidiun and its periphery from the distal surface to the proximal are divided into 10 layers as revealed in examination of the fine structures in the present work.
