Reed beds are wetland habitats with the dominance of Phragmites australis, which are inhabited by diverse communities of organisms of high conservation value, known to be good diagnostic species for conservation measures. We studied bees and wasps associated with ten reed bed types and with the galls of frit flies of the genus Lipara in hundreds of localities in central Europe between the years 2011 and 2017. Species assemblages differ among specific types of reed beds; these differences are prominent compared between the near-natural and anthropogenic sites. Species of high conservation value prefer wet meadows with flowering plants and a portion of common reed, or terrestrial reed beds near fishponds, rivers and streams. Similar species also inhabit temporary field wetlands. Reed beds in sand pits, quarries, enduro tracks, brown coal spoil heaps or power plant tailing ponds are inhabited by generalist species. Mowing, the most frequently used management tool for removing common reed, has a positive effect on species nesting in reed stalks but negative on those nesting in reed galls. It is thus necessary to implement mowing only of a part of the reed bed into the management tools and to leave some parts of the reed bed, as well as reed margins, untouched. A high number of small to large reed beds increases the biodiversity of bees, wasps and other invertebrates, and these habitats can serve as biodiversity hotspots in increasingly anthropized and agricultural landscapes.

芦苇是湿地栖息地的霸主地位芦苇，这是由高保护价值，已知的保护措施良好的诊断种群的生物多样化的社区居住。我们研究了与十种芦苇床类型以及Lipara属的果蝇蝇相关的蜜蜂和黄蜂在2011年至2017年之间，欧洲中部数百个地区的芦苇床种类有所不同。这些差异在近乎自然和人为的地点之间比较明显。具有较高保护价值的物种更喜欢在湿润的草地上种植开花植物，以及在鱼塘，河流和溪流附近的一部分普通芦苇或陆地芦苇床。相似的物种也栖息在临时的田间湿地中。沙坑，采石场，耐力赛道，褐煤渣堆或发电厂尾矿池中的芦苇床被多才多艺的物种居住。割草是最常用的去除常见芦苇的管理工具，对芦苇茎上的物种筑巢有积极影响，但对芦苇gall中筑巢的物种却有不利影响。因此，有必要仅将一部分芦苇床割入管理工具中，并保留部分芦苇床以及芦苇边缘。大量的小芦苇床到大芦苇床增加了蜜蜂，黄蜂和其他无脊椎动物的生物多样性，这些栖息地可以作为日益人为和农业景观中的生物多样性热点。
