Dermanyssus gallinae (poultry red mite, PRM) is a main ectoparasite of poultry that represents a serious economic threat to all farming systems, including cages and backyard flocks. In recent years, economic losses associated with this ectoparasite have progressively increased, mainly because of the lack of information regarding its population dynamics and appropriate control methods. In this study, we used a modified monitoring method to examine the in-house factors affecting the population density of D. gallinae. PRMs have been found in all poultry houses examined in Turkey. The largest population was detected in the front and back parts of the middle rows in cage systems as well as in perches in backyard systems. Relative humidity, light, and temperature might be the most affecting factors on the mite distribution inside the poultry houses. Besides, the mite populations are influenced mainly by the last (chemical) treatment date and the construction materials of the building. Dermanyssus gallinae were found to be the most dominant mite species (98.9%), followed by Cheyletus sp. (Cheyletidae); also some Acaridae (Tyrophagus spp.) and Oribatida were identified. Hence, further research on Cheyletus sp. is required to elucidate their predatory potential and develop future control strategies. This study contributes to understanding the PRM population behavior in poultry houses as well as their monitoring and control methods, which are key components in the appropriate application of integrated pest management programs.

Dermanyssus gallinae（家禽红螨，PRM）是一种主要的家禽体外寄生虫，对包括网箱和后院鸡群在内的所有养殖系统构成严重的经济威胁。近年来，与这种外寄生虫相关的经济损失逐渐增加，主要是因为缺乏有关其种群动态和适当控制方法的信息。在这项研究中，我们使用改进的监测方法来检查影响D. gallinae种群密度的内部因素. 在土耳其检查的所有禽舍中都发现了 PRM。在网箱系统的中间行的前部和后部以及后院系统的栖木中检测到最大的种群。相对湿度、光照和温度可能是影响禽舍内螨类分布的最大因素。此外，螨类种群主要受最后（化学）处理日期和建筑物的建筑材料的影响。Dermanyssus gallinae被发现是最主要的螨种（98.9%），其次是Cheyletus sp。（雪足虫科）；还鉴定了一些螨科（Tyrophagus spp.）和Oribatida。因此，进一步研究Cheyletussp. 需要阐明它们的掠夺潜力并制定未来的控制策略。本研究有助于了解禽舍中 PRM 种群的行为及其监测和控制方法，这是适当应用综合虫害管理计划的关键组成部分。
