Diversity, Abundance and Pollen Affinity of Wild Bee Pollinators of Almond: Insights From a Moroccan Orchard

ABSTRACT Almond trees are economically important and widely cultivated across the Mediterranean. Their yield depends on cross‐pollination by insects, yet their pollinators remain largely unknown, particularly in North Africa. This study investigated the diversity, abundance and pollen affinity of wild bee species in a Moroccan almond orchard. Using sweep netting and pan traps, a total of 813 specimens representing 104 species, 17 genera and 5 families were recorded in the studied orchard. Bee diversity and abundance peaked during the flowering phase, reflecting the key role of bloom phenology in shaping pollinator activity. The most species‐rich and abundant genera were Andrena , Eucera and Lasioglossum . In total, 26 species were identified as almond floral visitors (AFV), with Andrena flavipes and Andrena bimaculata being the most abundant floral visitors. Among them, palynological data identified eight species as almond pollen victors (APV), with a total of 182 plant‐bee interactions and confirmed strong almond pollen affinity for both Andrena species, particularly A. flavipes . While this study is limited to one orchard, it highlights the ecological importance of wild bees in Moroccan almond systems and underscores the potential of selecting native species to enhance pollination services, especially in light of reported pollination deficits. These findings support the development of conservation‐oriented management strategies aimed at sustaining pollinator diversity and crop productivity.
