Phoresy is a biologically mechanical phenomena where an immobile organism hitches on a other mobile organism to translocate. This behaviour is not studied very well on the field level especially between two important parasites infesting the same host. Parasite/parasite interaction is rarely studied through most biological host-parasite systems. Here, we evaluated the phoretic relation between parasitic chewing lice and hippoboscid flies (Pseudolynchia canariensis) on rock pigeons. A total of 69 captivated rock pigeons, Columba livia, were examined for the parasitic chewing lice and hippoboscid flies in Giza Zoo and two local farms near Cairo, Egypt. Results indicated that there is a positive correlation between infestation of hippoboscid flies and chewing lice. Also, the analysis of louse/louse interaction using ANOVA indicated a significant difference between the three chewing louse species which were recorded on the rock pigeons with relatively high abundance of two species, Columbicola columbae and Campanulotes compar. The analysis of hippoboscid flies' abundance and its relation with chewing lice infestation indicate a significant increase of lice intensity in case of high infestation with the fly. The level of hygiene of nest may be inversely related to level of parasite infestation. This work forms a step in the process of understanding parasite/parasite and host/parasite interactions using two parasitic species with a characteristic phoretic behaviour in nature.
寄养是一种生物力学现象，其中不动的生物体附着在另一个移动的生物体上进行迁移。这种行为在野外水平上研究得不是很好，特别是在两个寄生在同一宿主身上的重要寄生虫之间。寄生虫/寄生虫的相互作用在大多数生物宿主-寄生虫系统中很少被研究。在这里，我们评估了寄生在岩鸽身上的咀嚼虱和 hippoboscid 蝇（Pseudolynchia canariensis）之间的寄养关系。在埃及吉萨动物园和开罗附近的两个当地农场，总共检查了 69 只被捕获的岩鸽，以确定寄生的咀嚼虱和 hippoboscid 蝇。结果表明， hippoboscid 蝇和咀嚼虱的感染之间存在正相关。此外，使用方差分析对虱子/虱子相互作用的分析表明，在记录于岩鸽上的三种咀嚼虱中存在显著差异，这三种虱子的相对丰度较高，分别为 Columbicola columbae 和 Campanulotes compar。 hippoboscid 蝇丰度及其与咀嚼虱感染的关系分析表明，在苍蝇大量感染的情况下，虱子的强度显著增加。巢的卫生水平可能与寄生虫感染水平成反比。这项工作是使用两种具有自然特征寄养行为的寄生物种来理解寄生虫/寄生虫和宿主/寄生虫相互作用过程中的一个步骤。
