Before the bee was introduced, the honeybee was introduced into North America. It's just the unique thing about honeybees is they're so easily managed. There aren't many insects that you could take 30,000 of them in a box and move them into an almond orchard.
Wally Thurman of North Carolina State University and PERC talks with EconTalk host Russ Roberts about the world of bees, beekeepers, and the market for pollination. Thurman describes how farmers hire beekeepers to pollinate their crops and how that market keeps improving crop yields and producing honey. Thurman then discusses how beekeepers have responded to Colony Collapse Disorder--a not fully understood phenomenon where colonies disband, dramatically reducing the number of bees. The discussion closes with the history of bee pollination as an example of a reciprocal externality and how Coase's insight helps understand how the pollination market works.
