1. The intensification of farming practices, along with the loss and fragmentation of semi‐natural habitats within agricultural areas, has contributed significantly to insect decline worldwide including flower‐visiting aculeate Hymenoptera.
2. In this study aculeate Hymenoptera were collected using bi‐directional Malaise traps placed along farmland linear habitats across a range of farming intensities. The aim was to further our understanding of the value of farmland linear habitats to this insect group and in particular the Vespinae, an understudied subfamily.
3. Overall, significantly greater aculeate Hymenoptera species richness was found on extensive than on intermediate and intensive farms. Significantly more species and specimens were collected on the side of the traps adjacent to the linear habitats compared to the side which opened onto the fields. Aculeate Hymenoptera species richness was also significantly greater in dense hedgerows than in open hedgerows. Furthermore, two out of six Vespinae species, Vespula rufa and Vespula vulgaris, had significantly more individuals on extensive than intensive farms.
4. This study highlights that low‐intensity farming practices and farmland linear habitats, especially dense hedgerows, may enhance aculeate Hymenoptera occurrence in agricultural areas. It also demonstrates that Malaise traps set up along linear habitats across a range of farming intensities can make a significant contribution to knowledge regarding the biodiversity value of such areas. Given that selected Vespinae species follow similar trends to aculeate Hymenoptera, the possibility of using them as simple biodiversity indicators is worthy of further exploration.

使用Malaise诱集器评估各种耕作强度下与农田线性生境相关的无翅膜翅目

1. 耕作方式的集约化，再加上农业区域内半自然生境的丧失和破碎化，极大地促进了全世界昆虫的减少，包括访花的不规则膜翅目膜翅目。
2. 在这项研究中，使用沿着各种耕作强度沿农田线性生境放置的双向Malaise捕集器收集了无鳞的膜翅目。目的是使我们进一步了解农田线性生境对该昆虫类群，特别是维斯皮奈科（一个未得到充分研究的亚科）的价值。
3. 总体而言，与中型和集约化养殖场相比，粗放型膜翅目膜翅目物种丰富度明显更高。与向野外敞开的那一侧相比，在与线性栖息地相邻的捕集阱一侧收集的物种和标本明显多得多。在密集的树篱中，无翅膜翅目物种的丰富度也明显大于在开放的树篱中。此外，在六种维斯平藻物种中，粗大胡蜂（Vespula rufa）和寻常小胡蜂（Vespula vulgaris）在集约化养殖场上的个体明显多于集约化养殖场。
4. 这项研究强调指出，低强度耕作方式和农田线性生境，特别是茂密的树篱，可能会增加农业地区无翅膜翅目的发生。这也表明，在一系列耕作强度的线性栖息地上建立的Malaise陷阱可以对有关此类地区生物多样性价值的知识做出重大贡献。鉴于选定的维斯pinae物种遵循相似的趋势来使膜翅目成虫，将其用作简单生物多样性指标的可能性值得进一步探讨。
