  1. Provide artificial nest sites for solitary bees

    From 1988-1991, Bosch (1992) recorded rates of parasitism for the orchard bee Osmia cornuta, nesting in nest boxes comprising paper straws in milk cartons, drilled holes in wooden blocks, grooved wooden boards, or bundles of reed stem. Overall parasitism rates ranged from 5-18% of cells in wild populations, and 0.1-13% of cells in managed populations.
