High Death Rates in Bee Colonies

June 26, 2023

Honeybee colonies in the United States are facing a concerning trend according to an annual bee survey conducted by the University of Maryland and Auburn University. While the overall number of honeybee colonies has remained stable, the survey reveals a high death rate among managed colonies.

The High Mortality Rate and its Impact

The survey reports that nearly half of managed honeybee colonies in the United States have been lost, marking the second highest death rate on record. This loss, while staggering, is even more concerning when considering the vital role honeybees play in pollinating over 100 crops, including nuts, vegetables, berries, citrus fruits, and melons.

Contributing Factors

Several factors contribute to the high mortality rate of honeybee colonies. Parasites, such as the Varroa destructor mite, weaken the bees and make them susceptible to viruses. Pesticides further compromise their immune systems and foraging abilities. Starvation, caused by habitat loss and a lack of diverse food sources, exacerbates the issue. Additionally, the effects of climate change and extreme weather events pose additional challenges for these delicate pollinators.

Challenges Faced by Beekeepers

Beekeepers face the challenging task of maintaining the overall population of honeybee colonies. They invest significant resources in splitting and restocking hives, which involves finding or purchasing new queens and colonies. Commercial beekeepers play a vital role in replenishing losses and ensuring the stability of the bee colony population.

The Importance of Conservation Efforts

The significance of addressing the threats to honeybees cannot be overstated. While the current situation may not reach the crisis level observed 15 years ago, environmental threats persist. Honeybees are crucial for pollinating insect-dependent plants and maintaining diverse ecosystems. The growing demand for pollination from commercial bee colonies necessitates increased efforts to safeguard their populations and find sustainable solutions.
