A queenless hive can survive for several months, but its longevity depends on various factors such as environmental conditions, the availability of resources, and the behavior of the worker bees. Initially, the colony may lose a significant number of workers within the first month, but the remaining bees can persist until they eventually succumb to starvation or cold. This survival is surprising given the typical lifespan of forager bees, which is much shorter. However, without a queen to lay eggs and sustain the colony's population, the hive will eventually collapse.

Key Points Explained:

1. Survival Duration of Queenless Hives

   • Queenless hives can survive for several months, often longer than expected based on the lifespan of individual worker bees.
   • The survival period is influenced by factors such as the availability of food, the health of the remaining workers, and environmental conditions.

2. Biphasic Worker Loss

   • Worker loss in queenless hives occurs in two phases:
     • Initial Phase: A significant number of workers die within the first month due to stress, lack of resources, or natural attrition.
     • Extended Phase: The remaining workers persist for a longer period, often until they die of starvation or cold.

3. Role of the Queen in Colony Sustainability

   • The queen is essential for laying eggs and maintaining the population of the hive.
   • Without a queen, the colony cannot produce new workers, leading to a gradual decline in numbers and eventual collapse.

4. Environmental and Resource Factors

   • The availability of nectar, pollen, and other resources can extend the survival of a queenless hive.
   • Harsh weather conditions, such as cold temperatures, can accelerate the decline of the colony.

5. Behavioral Adaptations of Worker Bees

   • In the absence of a queen, worker bees may attempt to lay unfertilized eggs, which develop into drones.
   • However, this behavior does not sustain the colony in the long term, as drones do not contribute to foraging or other essential tasks.

6. Use of Tools Like the Hive Brush

   • Regular maintenance and inspection of the hive, using tools like the hive brush, can help identify queenlessness early.
   • Early detection allows beekeepers to take corrective actions, such as introducing a new queen or merging the colony with another.

7. Beekeeper Intervention

   • Beekeepers can intervene to save a queenless hive by:
     • Introducing a new queen or queen cell.
     • Merging the colony with a queenright hive.
     • Providing supplemental feeding to support the remaining workers.

Understanding the dynamics of a queenless hive and taking proactive measures can help beekeepers maintain healthy and productive colonies.
