Prevent escape of commercial bumblebees from greenhouses
Koide et al. (2008) tested whether netting could prevent the escape of the buff-tailed bumblebee B. terrestris from four greenhouses with different netting techniques in Japan, where netting is a legal requirement for greenhouse growers using bumblebee colonies. The study showed that nets mounted on the outside of windows with packers (tubes that hold plastic film) or Vinipets (U-shaped devices) prevented bumblebee escape, providing the nets were regularly checked and maintained. Nets mounted on the inside, or on the outside with clips, allowed bees to escape. Double netting of doors, even with a plastic vestibule, also allowed bumblebees to escape, but zipped, netted entrances prevented escape as long as the entrance was weighted at the bottom.
