Bee diseases are health issues that affect honeybees and can lead to colony decline. Common diseases include American foulbrood, a bacterial infection that affects larvae, and Varroa mites, which are parasites that weaken bees by feeding on their blood. These diseases can spread quickly and may result in the loss of entire colonies if not managed properly. Preventing bee diseases involves good hive management practices, such as regular inspections and maintaining strong colonies. Beekeepers can also use treatments and medications to control pests and infections. Awareness and education about these diseases are essential for the health of honeybee populations and the ecosystems they support.
