熊蜂（Bombus spp.）作为农作物和野花的传粉者，在农业系统中发挥着关键作用。然而，由于农业集约化，该分类单元已严重减少。保护工作主要集中在为熊蜂提供整个夏季的饲料资源，但在早春筑巢期间提供合适的栖息地可能是增加当地熊蜂数量的更有效方法。本研究评估了三种不同农田栖息地类型（树篱、田边和草地）的吸引力，以及苏格兰农村管理计划下各自土地管理方案对大黄蜂蜂王在蜂王羽化和蜂群建立期间寻找巢址和觅食的相对优点。对于春季蜂王来说，树篱是最没有吸引力的栖息地类型。乡村管理物种丰富的草地具有复杂的植被结构，吸引了寻找巢穴的蜂王，而被废弃的允许自然更新的草地则含有更多的花朵，吸引了觅食的蜂王。田野边缘栖息地是最具吸引力的栖息地类型，乡村管理田野边缘以相对较高的密度吸引了巢穴搜索和觅食蜂王。这种管理方案包括播种混合草，形成寻找巢穴的蜂王所喜欢的复杂植被结构，但定期的干扰会导致早期开花的大黄蜂饲料植物的入侵。这些发现表明，应该有可能制定简单的组合管理策略，以在农田上提供合适的筑巢地点和春季饲料资源，促进熊蜂群体的基础，从而促进农业环境的丰富。 (C) 2009 年，爱思唯尔有限公司出版。
Bumblebees (Bombus spp.) play a key role within agricultural systems as pollinators of crops and wild flowers. However, this taxon has suffered severe declines as a result of agricultural intensification. Conservation efforts largely focus on providing forage resources for bumblebees through the summer, but providing suitable habitat during the period of nest foundation in early spring could be a more effective method of boosting local bumblebee populations. This study assesses the attractiveness of three different farmland habitat types (hedgerow, field margin and grassland), and the relative merits of respective land management prescriptions under the Scottish Rural Stewardship scheme to nest site searching and foraging bumblebee queens during the period of queen emergence and colony foundation. Hedgerows were the least attractive habitat type to spring queens. Rural Stewardship species-rich grassland comprised a complex vegetation structure attracting nest site searching queens, whilst grassland that had been abandoned allowing natural regeneration contained more flowers, attracting foraging queens. Field margin habitats were the most attractive habitat type, and Rural Stewardship field margins attracted both nest site searching and foraging queens at relatively high densities. This management option consisted of a sown grass mix, giving rise to the complex vegetation structure preferred by nest site searching queens, but regular disturbance allowed invasion by early flowering bumblebee forage plants. These findings suggest that it should be possible to develop simple combined management strategies to provide both suitable nesting sites and spring forage resources on farmland, promoting bumblebee colony foundation and therefore abundance in the agricultural environment.
