The construction and function of a self-warmed, portable incubator for sealed worker honey bee (Apis mellifera) brood is described here.This incubator can be used by both static and migratory beekeepers.The prerequisites of a rational use of a portable incubator in the early to middle spring are cited.A brief overview of the possible uses of the incubator is given. Finally, comparisons with other known techniques related to swarm prevention, to production of new colonies and/or to treatment of varroosis are also made.
