Commercially managed bees are available for pollination services and are used in large commercial fields, small gardens, or enclosures such as greenhouses and screen houses. We investigated the use rate and number of commercial bees such as bumblebees, honeybees and mason bees for the pollination of 10 major horticultural crops and fruit trees in Korea. The use rates of bumblebees for 10 major horticultural crops and fruit trees were approximately 7.9% and 2.8% in 2009, respectively. The use numbers of bumblebees as pollinators was more than 64,345 colonies which included 51,400 for 10 major horticultural crops and 12,945 colonies for 10 major fruit trees, in 2009. The use rate of honeybees as a pollinator for 10 major horticultural crops in greenhouses and fruit trees were approximately 48.0% and 7.7%, respectively. The number of hives used for 10 horticultural crops and fruit trees was estimated to be 305,216 and 32,386, respectively. The number of honeybees hives used for pollination of 10 major horticultural crops and fruit trees was estimated to be 337,602. The use numbers of honeybees as pollinators was more than 337,602 hives in 10 major horticultural crops and fruit trees, in 2009. The number of honeybee hives used as pollinators of outside crops, including many fruits and vegetables, was estimated to be more than 500,000. The value of honeybees as pollinators was estimated to be more than 8.5% to 15.0% of total Korean beekeeping products. The rate of use of mason bees for 10 major fruit trees was approximately 3.3%. The number of mason bees individuals used for 10 major fruit trees was estimated to be 1,350,000. The value of commercial insect pollinators in 2009 in Korea was estimated at more than $45 million.
