The rate of gregariousness and intra- and inter-specific attractivity were evaluated under laboratory conditions in five species of Dermaptera. The three species of the genus Forficula (Forficula auricularia L., F. decipiens Gené and F. pubescens Gené) showed distinctly gregarious behaviour in old larvae and adults in the pre-reproductive phase. This gregariousness was seen at the intraspecific level and also among individuals of different species. The other two species, Labidura riparia Pallas and Euborellia moesta Gené, were randomly distributed over the available shelters, with no distinct tendency for aggregation or isolation. In individual tests, insects of all five species were attracted by shelters previously visited by conspecifics in preference to control shelters. For the two non-gregarious species, this phenomenon might function as a burrow marker. The same tests showed an interattractivity for four of the species studied. Only L. riparia did not respond to the trails of the four other species, although its trails were attractive to the other species. The pheromonal nature of the substances involved in the interspecific relationships and the involvement of behaviour in the biology and speciation of Dermaptera are discussed.
在实验室条件下，对五种革翅目昆虫的群居率以及种内和种间吸引力进行了评估。蠼螋属的三个物种（耳蠼螋Forficula auricularia L.、伪蠼螋F. decipiens Gené和毛蠼螋F. pubescens Gené）在生殖前期的老龄幼虫和成虫阶段表现出明显的群居行为。这种群居行为在种内以及不同物种个体之间都有体现。另外两个物种，即河岸肥螋Labidura riparia Pallas和暗褐肥螋Euborellia moesta Gené，随机分布在可用的庇护所中，没有明显的聚集或隔离倾向。在个体测试中，所有五个物种的昆虫都更倾向于选择同种个体先前光顾过的庇护所，而不是对照庇护所。对于这两个非群居物种来说，这种现象可能起到洞穴标记的作用。相同的测试表明，所研究的四个物种之间存在种间吸引力。只有河岸肥螋对其他四个物种的踪迹没有反应，不过它的踪迹对其他物种具有吸引力。文中讨论了参与种间关系的物质的信息素性质以及行为在革翅目生物学和物种形成中的作用。
