Robbing in beekeeping refers to the phenomenon where honeybees from one colony attempt to steal honey and other resources from another colony's hive. It typically occurs when forager bees from a weaker or struggling colony, or even from a strong colony during times of dearth, discover an unguarded or weakened hive and exploit the opportunity to plunder its honey and other valuable resources. Robbing can lead to significant colony losses, weakened populations, and increased stress on bee colonies. Here's how robbing occurs and strategies for prevention and control:
1. How Robbing Occurs:
Weak or Unprotected Hives: Robbing often targets weak or unprotected colonies that may have reduced defensive capabilities or be unable to adequately protect their hive entrances.
Scent of Honey: Forager bees from the robbing colony are attracted to the scent of honey and other hive products, which they detect while foraging.
Initial Aggression: When foragers from the robbing colony discover a vulnerable hive, they may initially exhibit aggressive behavior, attempting to gain access to the hive and overpower the defending bees.
Feedback Loop: As the robbing bees gain access to the hive and begin stealing honey, they release alarm pheromones that attract more bees from their colony to join in the plundering. This creates a feedback loop that intensifies the robbing behavior.
2. Prevention and Control:
Maintain Strong Colonies: One of the best ways to prevent robbing is to ensure that colonies are strong and healthy. Strong colonies are better able to defend their hives against robbers. Regular inspections, disease management, and supplemental feeding during times of dearth can help maintain colony strength.
Reduce Hive Entrances: Narrowing the hive entrance with an entrance reducer or entrance gate can help deter robbers by making it easier for defending bees to defend the entrance.
Provide Adequate Ventilation: Proper hive ventilation can help reduce the buildup of scent within the hive, making it less attractive to robbers.
Use Robbing Screens: Robbing screens are devices that cover the hive entrance with a mesh or screen, allowing bees from the colony to enter and exit while preventing robbers from gaining access. This helps protect weaker colonies from robbing attacks.
Feed Colonies Inside the Hive: If supplemental feeding is necessary, feed colonies inside the hive using internal feeders rather than placing feeders outside the hive, which can attract robbers.
Manage Colony Odor: Avoid spilling honey or other hive products outside the hive, as the scent can attract robbers. Promptly clean up any spilled honey or comb debris.
Monitor Hive Activity: Regularly monitor hive entrances for signs of robbing behavior, such as increased aggression, fighting, and bees attempting to enter other colonies' hives. Take immediate action if robbing is detected.
By implementing these preventive measures and promptly addressing any signs of robbing, beekeepers can help protect their colonies from the damaging effects of robbing and maintain strong, healthy bee populations.
