Osmia cornifrons is a highly efficient pollinator of rosaceous tree fruits (Pyrus and Prunus spp.). It is managed commercially in Japanese orchards, and it has been introduced into the eastern United States. Due to its effectiveness, docility, ease of handling and short flight range, it is well adapted for use on small farms.
