Data for: Hedgerows have contrasting effects on pollinators and natural enemies and limited spillover effects on apple production

Agricultural intensification has resulted in a decline in insect biodiversity and threatens the provision of valuable ecosystem services. Agri-environment schemes (AESs) have been implemented in an effort to conserve biodiversity on farmland and increase agricultural sustainability, but their effectiveness can vary widely. To better determine which factors influence AES effectiveness, the relative roles of local habitat features, habitat quality, and landscape context need to be further explored. The aim of this study was to determine the most important factors influencing field margin AES effectiveness in commercial apple orchards, in terms of arthropod biodiversity conservation and ecosystem service provision. We surveyed wild bees and aphid natural enemies in field margins and apple trees in 20 orchards, ten bordered by hedgerow field margins (an AES) and ten with herbaceous field margins (no hedgerows present, not an AES). We considered field margin floral resources and the cover of..., ,

农业集约化已导致昆虫生物多样性下降，并威胁到宝贵生态系统服务的供给。农业环境计划（Agri-environment schemes, AESs）已被推行以保护农田生物多样性并提升农业可持续性，但其实施效果差异显著。为更精准地明确影响农业环境计划实施效果的因素，亟需进一步探究本地生境特征、生境质量与景观背景的相对作用。本研究旨在从节肢动物生物多样性保护与生态系统服务供给的维度，确定商业苹果园中影响农田边际带农业环境计划实施效果的关键因素。我们对20个苹果园的农田边际带与苹果树开展了野生蜂与蚜虫天敌调查，其中10个果园以树篱型农田边际带为边界（实施农业环境计划），另外10个果园配置草本型农田边际带（无树篱，未实施农业环境计划）。本研究考量了农田边际带的花卉资源与……的覆盖度，
