【Abstract】 Osmia cornifrons and O.longnicornis were released and their biological characteristics were studied from 2000 to 2001 in an apple-pear orchard in the Yanbian area, China. The results show that both species of them can establish nest and reproduce successfully in the apple-pear orchard. O.cornifrons visited 4?158 flowers per day, while O.longnicornis visited 4?359 flowers per day. O.longnicornis is a prospective pollinator for apple-pears.更多还原
