Abstract. Pollinator insects are essential for the pollination of many crops and wild plants. Recent declines in insect population pose significant challenges for maintaining pollination services. Habitat loss and landscape homogenization are among the primary drivers of these declines. In order to monitor and assess populations of pollinating insects, precise and accurate methods are required. A common method to collect pollinators is pan traps, but this method suffers from a bias due to surrounding flower frequency, yet this remains untested at the large spatial scale such as the landscape. Understanding how different pollinator sampling methods reflect the impact of landscape composition on pollinator communities is critical for designing robust monitoring schemes that can lead to effective conservation strategies. This study investigates how two common pollinator sampling methods – insect nets and pan traps – measure the abundance, diversity, and composition of pollinator communities in sweet-cherry orchards (Prunus avium) in Belgium. The study also examines how pollinator data obtained by these methods relate to the surrounding landscape, specifically the amount of seminatural habitat and intensive fruit cultivation. We conclude that both methods provided similar sampling efficiencies, yet they captured different subsets of the pollinator community. Insect nets caught a higher abundance and species richness of bumblebees, while pan traps caught higher solitary bee abunda...
