The spectrum of Mesostigmata mite species that are phoretic on the bark beetle Ips typographus has been well described. However, phoretic mite abundance has mostly been quantified by researchers who used only a single method for capturing bark beetles: pheromone traps. We therefore compared mite abundance using two beetle-capture methods. At a single location with high numbers of I. typographus in the eastern Czech Republic in 2013, beetles were collected with pheromone traps and from infested logs placed in emergence traps. In total 29,589 I. typographus beetles were captured using the two methods. Mite abundance was assessed on 2400 beetles from pheromone traps and on 955 beetles from emergence traps; in total 5805 phoretic mesostigmatid mites were detected. Six species of phoretic mites were captured using pheromone traps and four species using emergence traps. The number of phoretic mites per beetle was higher for beetles captured in emergence traps than for beetles captured in pheromone traps. The most abundant mite species overall were Dendrolaelaps quadrisetus, Uroobovella ipidis, and Trichouropoda polytricha. The seasonal dynamics of phoretic mites paralleled the seasonal dynamics of their hosts.

在树皮甲虫Ips typographus上发色的中生食螨物种的光谱已得到很好的描述。但是，隐身螨的丰度主要是由研究人员量化的，他们只使用一种方法捕获树皮甲虫：信息素诱捕剂。因此，我们使用两种甲虫捕获方法比较了螨虫的丰度。2013年，在捷克共和国东部一个印刷术高产的地方，甲虫用信息素诱捕器收集了甲虫，并从放出诱捕器中的受感染原木中收集了甲虫。总计29,589个I. typographus使用两种方法捕获了甲虫。对来自信息素陷阱的2400株甲虫和来自出苗陷阱的955株甲虫进行了螨虫丰度评估。总共检测到了5805个突中线虫。使用信息素诱捕器捕获了6种昆虫螨，使用出苗捕获器捕获了4种昆虫。在出苗陷阱中捕获的甲虫比在信息素陷阱中捕获的甲虫，每个甲虫的螨数量更高。总体上最丰富的螨虫物种是Dendrolaelaps quadrisetus，Uroobovella ipidis和Trichouropoda polytricha。隐身螨的季节性动态与宿主的季节性动态平行。
