大多数甲螨以其外分泌的油腺分泌物而闻名，其中已描述了一百多种不同的化学成分（烃类，萜烯，芳香族化合物和生物碱）。这些分泌物的生物学功能对大多数物种来说仍然是个谜，但警报信息素和异源激素功能已经被假设，并在某些情况下得到证实。在这里，我们测试了不同的实验刺激，以诱导释放防御分泌物的模型oribatid miteArchegozetes longisetosusAoki.Therefore各种机械刺激并没有导致一个可重复的和完全驱逐的油腺分泌物，重复处理己烷导致完全放电。生活史参数，如生存，发育和繁殖不受己烷治疗。重复己烷处理也导致筛状幼鱼油腺的完全耗尽。
Most oribatid mites are well known for their exocrine oil gland secretions, from which more than a hundred different chemical components (hydrocarbons, terpenes, aromatics and alkaloids) have been described. The biological functions of these secretions have remained enigmatic for most species, but alarm-pheromonal and allomonal functions have been hypothesized, and demonstrated in some cases. Here, we tested different experimental stimuli to induce the release of defensive secretions in the model oribatid miteArchegozetes longisetosusAoki.Whereas various mechanical stimuli did not result in a reproducible and complete expulsion of oil gland secretions, repeated treatments with hexane led to complete discharge. Life history parameters such as survival, development and reproduction were not influenced by the hexane treatment. Repeated hexane treatments also resulted in a complete depletion of oil glands inEuphthiracarus cribrariusBerlese.
