SOME CHARACTERISTICS OF KOREAN INDIGENOUS BUMBLEBEE SPECIES (HYMENOPTERA; BOMBUS SSP.) UNDER LABORATORY CONDITIONS
The hibernated queens of seven Korean native bumblebee species were collected throughout Korea from March 23 to May 14, 1999. Among them, three species, B. ignitus, B. ardens ardens and B. hypocrita sapporoensis, established colonies under laboratory conditions (28oC, 29oC, 65%; 8L/16D); 48.9%, 38.9% and 25.0%, respectively. The queens of B. ardens ardens and B. hypocrita sapporoensis laid the first brood in five days and B. ignitus in nine days after field collection. The first worker bees of B. ardens ardens, B. ignitus and B. hypocrita sapporoensis emerged in 26 days or 28 days after field collection, respectively. The emergence of the first male of three species, B. ardens ardens, B. hypocrita sapporoensis and B. ignitus took place in 50 days, 64 days and 73 days, with the emergence of new queens in 15, 10 and 7 day intervals. It is also noticeable that a colony of B. ignitus developed to 456 heads with 262 worker bees, 74 males and 120 virgin queens.
