摘　　要：对臭蜣螂CoprisochusMotschulsky体壁的组织学结构进行了光镜观察。用伊红和马洛赖氏三色法染色可见体壁尤其在腹壁的折叠处及膜翅壁中存在着胶原纤维。鞘翅中有内腔 ,具皮细胞 ,鞘翅背部表皮下陷形成桥墩状结构以支撑加固鞘翅腔并减轻重量。膜翅的背腹壁之间也具有内腔和皮细胞 ,并充满油脂腺 (经分析是棕脂肪细胞腺 )及其分泌物。足的肌肉束中被大量棕脂肪细胞腺环绕。棕脂肪细胞的存在为周围器官提供所需能量 ,并有减轻重量和润滑的作用。体壁表面具有大量突起、刚毛及大量粗细不等的管道与其下相通 ,加上大量油脂腺及其分泌机能 ,为其体表的减粘特性提供了形态和化学基础。The histological structures of the dung beetle, Copris ochus Motschulsky integument was studied by microscope. There are collagenous fiber in body integument especially the ventral integument and the hymenopterous integument discovered by the H.E. and Mallory’s staining. Also cavity in the elytra was found, which are supported by pier formed pillars formed by integument sinking for supporting and reducing weight. There are cavities in the hymenoptera which are full of the brown fat glands and their secretion. The dermal cells were found in the cavities of the elytra and hymenopterous wing which suggest that the elytra and the hymenopterous wing are living structures. A lot of the brown fat glands are surrounding the muscle in the leg to provide energy and decreasing friction between muscles. There are a lot of protrusions, setae and pore canals of different diameters communicating with the outside of the body. Those structures and lots of the oil glands with their secretions provide the morphological and chemical basis for decreasing the integument stickiness.
