Abstract or Summary
  • Out of 53 queens captured for initiating colonies in the laboratory, 33 laid eggs (62 percent), 29 of these produced colonies (55 percent), and 14 produced queens (26 percent). A behavioral model depicts the activities of queens from spring emergence through colony development. A discussion of its application to bumble bee domestication is made. New queens entered a diapause under laboratory conditions, and their dependence on a "proper" colony environment for doing so is suggested. The changes in fat body and ovary development support the concept of a fat body timer responsible for maintaining diapause. Eggs laid by new queens of B. occidentalis were largely nonviable and those which hatched died. A discussion of the problem in terms of queen motivation and inadequate releasers for maternal behaviors is presented. Artificial insemination of bumble bee queens is feasible. Sperm collection, insemination techniques, the female reproductive anatomy, and suggestions for improvements are included.
