Wildflower strip plantings in intensive agricultural systems have become a widespread tool for promoting pollination services and biological conservation because of their use by wasps and bees. Many of the trap-nesting wasps are important predators of common crop pests, and cavity-nesting bees that utilize trap-nests are important pollinators for native plants and many crops. The impact of wildflower strips on the nesting frequency of trap-nesting wasps or bees within localized areas has not been thoroughly investigated. Trap-nests made of bamboo reeds ( sp.) were placed adjacent to eight 0.1 ha wildflower plots and paired fallow areas (control plots) to determine if wildflower strips encourage the nesting of wasps and bees. From August 2014 to November 2015, occupied reeds were gathered and adults were collected as they emerged from the trap-nests. Treatment (wildflower or fallow plots) did not impact the number of occupied reeds or species richness of trap-nesting wasps using the occupied reeds. The wasps , , , and spp. were the most common trap-nesting species collected. Less than 2% of the occupied reeds contained bees, and all were from the genus . The nesting wasp and bee species demonstrated preferences for reeds with certain inside diameters (IDs). The narrow range of ID preferences exhibited by each bee/wasp may provide opportunities to take advantage of their natural histories for biological control and/or pollination purposes.
在集约化农业系统中，由于黄蜂和蜜蜂会利用野花带，因此种植野花带已成为促进授粉服务和生物保护的一种广泛使用的手段。许多筑巢诱捕型黄蜂是常见农作物害虫的重要捕食者，而利用筑巢诱捕器的筑巢型蜜蜂则是本地植物和许多农作物的重要传粉者。野花带对局部区域内筑巢诱捕型黄蜂或蜜蜂筑巢频率的影响尚未得到充分研究。将由竹芦苇（物种）制成的筑巢诱捕器放置在八个0.1公顷的野花地块和配对的休耕地（对照地块）附近，以确定野花带是否会促进黄蜂和蜜蜂筑巢。从2014年8月到2015年11月，收集被占用的芦苇，并在成虫从筑巢诱捕器中羽化时收集成虫。处理方式（野花地块或休耕地块）并未影响被占用芦苇的数量，也未影响使用被占用芦苇的筑巢诱捕型黄蜂的物种丰富度。黄蜂、、、和属是收集到的最常见的筑巢诱捕物种。被占用的芦苇中不到2% 含有蜜蜂，且所有蜜蜂均来自属。筑巢黄蜂和蜜蜂物种对具有特定内径（ID）的芦苇表现出偏好。每种蜜蜂/黄蜂表现出的内径偏好范围较窄，这可能为利用它们的自然习性进行生物防治和/或授粉目的提供机会。
