The Orchard Bee Association (OBA) was started in Modesto, CA in 2009 by a team of independent businesses, orchard managers, and researchers to accelerate the production and use of orchard mason bees (Osmia lignaria, O. cornifrons, O. cornuta, and O. rufa) in various spring crops and orchards. We encourage a role of stewardship, preservation, and enhancement of orchard bee populations as well as responsible wild bee management practices to preserve local genetic stock of bees with respect to elevation, climate, and local flora.
OBA has an annual meeting for members to present orchard bee research, exchange ideas and concepts, and to discuss organizational affairs. Other goals of the annual meeting are to facilitate educational awareness to the general public about orchard bees. Our website aims to provide resources to members and to the public as well as promoting international collaboration. OBA provides a listing of resources such as distributors of local orchard bees and supplies. In 2014, OBA became a legally recognized 501(c)3 not-for-profit professional society governed by a board comprised of members.
