Abstract
Studying the pollen preferences of introduced bees allows us to investigate how species use host-plants when establishing in new environments. Osmia cornifrons is a solitary bee introduced into North America from East-Asia for pollination of Rosaceae crops such as apples and cherries. We investigated whether O. cornifrons (i) more frequently collected pollen from host-plant species they coevolved with from their geographic origin or (ii) prefer hosts-plant species of specific plant taxa independent of origin. To address this question, using pollen metabarcoding, we examined the identity and relative abundance of pollen in larval provisions from nests located in different landscapes with varying abundance of East-Asian and non-Asian plant species. Our results show that O. cornifrons disproportionately, yet not exclusively, collected pollen from their native range. Plants in the family Rosaceae were their most preferred pollen hosts, where they differentially collected species native to East-Asia, Europe, or North America depending on the landscape. Our results suggest that while O. cornifrons more frequently collect pollen of East-Asian origin, the collection of pollen from novel species within their phylogenetic familial affinities can facilitate pollinator establishment. This phylogenetic preference highlights the effectiveness of O. cornifrons as crop pollinators of a variety of Rosaceae crops from different geographic origins. Our results imply that globalization of non-native plant species may ease the naturalization of their coevolved pollinators outside of their native range.
