摘　　要：采用扫描电镜技术观察并描述了臭蜣螂Coprisochus头部、胸腹部和足部体表上的凹陷和刚毛的结构。发现有 4种简单的凹陷 ,其三维结构、边缘类型和位于凹陷中央的带孔刚毛的长度在身体不同部位均有不同。体壁上还有中央具隆起的凹陷 ,其中心具带孔刚毛 ;或缺中心刚毛但在其半环状外边沿上具一小刚毛的凹陷。简单凹陷广泛分布于除腹部以外的各部分 ,但具中央隆起的凹陷仅出现在前胸背板 ,具半环状外边沿的凹陷出现在腿节上。在鞘翅纵沟纹的念珠状结中有管状开口。体壁上还有大小和形状不同的刚毛 ,它们不同于生于凹陷的刚毛。凹陷和刚毛的分布及形态构成体表的非光滑表面 ,作者探讨了这些结构与体表减粘脱附功能的关系。Understanding the integument structure of edaphic insects helps discover the unstickness mechanism of these insects and offer clues for bionics.Scanning electron microscopy (SEM) was used to observe the structure of pits and setae of the integument of the head, body and legs of the dung beetle, Copris ochus Motschulsky. Four kinds of simple pits were found, that varied from one part of the body to another in their dimensions, types of rims and the length of a centrally located, socketed seta. In addition, there were pits that had a mound in the center containing a central socketed seta, and pits that lacked a central seta, but had a small one at the top of a semicircular rim. Simple pits, of one kind or another, occurred widely over the body, except for the abdomen; pits with mounds were present on the prothorax, and those with semicircular rims only on the tibia. There also were openings of ducts in the nodes of elytral grooves that often contained accumulations of some substance. There was a variety of sizes and types of setae other than those associated with pits, especially on the head and legs. The distribution and form of pits and setae forms unsmooth surface which minimize adherence of particles to body surface, but secretions and cuticular chemicals also may contribute to the non adherent properties of these insects.
