本文叙述了昆虫卵沿着产卵管运动的机理。一系列向后定向的鳞片，位于沿着产卵器阀的内部，当卵从输卵管中出现时抓住卵的表面，并且当阀来回摆动时使卵沿着产卵器移动。产卵器鳞片的形态进行了检查，扫描电子显微镜，并比较了22种。昆虫的20个家族该机制也证实了直接操纵麻醉昆虫的产卵器。产卵器鳞片的长度从1-30 μ m不等，并且在不同物种中可以是刺状、梳状或鳞片状结构。Caddis-flies（毛翅目）是唯一一组没有产卵器鳞片的检查。其中一种，Philanisusplebeius步行者，有纵向脊沿着其产卵器阀的内表面。在这项研究中检查的石蛾蝇种缺乏产卵器鳞片的关系，他们的行为和可能的产卵地点进行了讨论。
This paper describes the mechanism by which eggs are moved along the length of the ovipositor of insects. A series of posteriorly orientated scales, located along the inside of the ovipositor valves, catch the surface of the egg as it emerges from the oviduct and move it along the ovipositor as the valves oscillate back and forth. The morphology of ovipositor scales is examined by scanning electron microscopy and is compared for 22 spp. in 20 families of insects. The mechanism is also confirmed by direct manipulation of the ovipositor of an anesthetized insect. Ovipositor scales vary in length from 1-30 .mu.m and can be spine-like, comb-like or scale-like in structure in different species. Caddis-flies (Trichoptera) were the only group examined which did not possess ovipositor scales. One species, Philanisus plebeius Walker, has longitudinal ridges along the inside surface of its ovipositor valves. The lack of ovipositor scales in the caddis-fly species examined in this study is discussed in relation to their behavior and possible oviposition sites.
