Common Bee Diseases: Chalkbrood
If you’re a beekeeper, you may have heard of chalkbrood – a fungal infection that can be harmful to honey bee larvae. This honey bee disease is caused by the fungus Ascosphaera apis and can severely weaken bee colonies.
Chalkbrood causes infected larvae to turn into a hard, chalk-like substance, making it difficult for worker bees to remove them from the hive. Normally, worker bees will carry dead larvae out of the hive to prevent the spread of diseases.
Unfortunately, chalkbrood can be challenging to control. It thrives in moist conditions, and overcrowded hives with poor ventilation can exacerbate the problem. Additionally, chalkbrood can spread rapidly, negatively affecting honey bee populations.
There are ways to prevent chalkbrood from taking hold in your hive. By taking measures to ensure proper ventilation, reducing overcrowding, and maintaining hygienic hive conditions, you can reduce the risk of a chalkbrood outbreak.
If an outbreak does occur, you may need to remove and destroy any infected comb to prevent further spread.

| Oil Traps | A trap that involves placing a container with oil on top of the hive, which traps beetles before they can move inside the hive. |
| Sticky Traps | Sticky traps coated with oil or adhesive material that capture beetles that venture onto them. |
By using these small hive beetle control methods, beekeepers can help maintain the overall health of their hives and promote a strong and thriving bee population.
Wax Moths: Masters of Waxy Destruction
Wax moths, also known as bee moths, are unwelcome guests in any apiary. While their larvae, known as waxworms, play a beneficial role in the environment by breaking down abandoned beehives, their presence in active hives can be devastating.
These moths can wreak havoc on your honey production and damage your hive infrastructure. Let’s delve deeper into the world of wax moths:
Understanding the Waxy Foe
There are two main culprits you might encounter:
- The Greater Wax Moth (Galleria mellonella): This larger moth boasts a wingspan of up to 3 centimeters and prefers weak or neglected hives.
- The Lesser Wax Moth (Achroia grisella): This smaller moth, with a wingspan of around 1.5 centimeters, is more aggressive and can infest even strong colonies.
Both species share similar life cycles, laying eggs near cracks and crevices in the hive. Their larvae hatch and feast on beeswax, pollen, and honey, creating tunnels and causing significant damage.
Signs of a Wax Moth Infestation
A vigilant beekeeper can spot the signs of a wax moth invasion:
- Presence of adult moths: These small, brown moths are most active at night and may be seen fluttering around the hive entrance.
- Webbing and silken tunnels: The larvae spin silken tunnels throughout the hive, creating a messy and unsanitary environment.
- Damage to wax combs: Look for chewed and discolored combs, with sunken cappings and potential holes.
- Presence of frass: Frass, the droppings of the larvae, resembles sawdust and can be found on the hive floor or around frames.
Combating the Waxy Menace
Early detection is key to successfully managing a wax moth infestation. Here are some effective strategies:
- Maintain strong hives: Strong colonies are better at defending themselves against pests. Ensure proper beekeeping practices to keep your bees healthy and productive.
- Regular inspections: Regularly inspect your hives for signs of moth activity, focusing on areas around frames and cracks.
- Freeze-infested frames: Freezing-infested frames for at least 48 hours can kill moth eggs and larvae.
- Trap adult moths: Use pheromone traps to attract and capture adult moths, preventing them from laying eggs.
- Moth-proof your apiary: Ensure good ventilation and close any potential entry points for moths, such as cracks or gaps in hive walls.
By implementing these strategies, you can effectively manage wax moth populations and protect your valuable beehives. Remember, a proactive approach is essential to maintain a healthy and thriving apiary.
Braula Flies: Not Quite a Bee Disease, But Still a Hive Nuisance
While not technically classified as a bee disease, Braula flies can be a nuisance to honeybee colonies.
Unlike other harmful bee pests, these wingless insects don’t directly harm bees or their brood.
However, their presence can still disrupt the hive’s efficiency and overall well-being. Understanding Braula flies and their impact on honeybee health is crucial for effective beekeeping practices.
Appearance and Lifecycle
Braula flies are tiny, red-brown insects with six legs and a hairy body. Lacking wings, they hitch a ride on adult honeybees, clinging to them with specialized claws on their front legs.
The females lay small, white eggs throughout the hive, but only those laid on capped honeycombs have a chance of hatching. The larvae feed on honey and honeycomb debris before pupating and emerging as adult flies, continuing the cycle within the hive.
Impact on the Hive
While Braula flies don’t directly harm bees or their brood, their presence can still negatively impact the hive in several ways:
- Competition for Resources: Though small, Braula flies compete with bees for nectar and pollen at the honeybee’s mouthparts, potentially reducing the amount of food available for developing larvae and adult bees.
- Stress and Disruption: The constant presence of flies on their bodies can be stressful and disruptive to bees, potentially affecting their foraging behavior and overall hive productivity.
- Disease Transmission: Though not confirmed, some research suggests Braula flies might act as vectors for certain bee diseases by carrying pathogens between bees and hives.
Management Strategies
Fortunately, Braula flies are rarely found in significant numbers in healthy, well-managed beehives. However, if you suspect a Braula fly infestation, several strategies can help:
- Strong Colony Management: Maintaining strong, healthy colonies with sufficient resources like pollen and nectar is crucial. Strong bees are better equipped to handle the presence of Braula flies and resist other bee diseases.
- Hive Inspections: Regular hive inspections allow beekeepers to monitor for signs of Braula flies, such as the presence of adult flies or their eggs on capped honeycombs.
- Limited Intervention: Due to the minimal harm they cause, chemical treatments specifically targeting Braula flies are generally discouraged. In most cases, maintaining strong colonies and good beekeeping practices are sufficient to manage their populations.
By understanding the role of Braula flies and implementing proper beekeeping practices, beekeepers can minimize their impact and ensure the health and productivity of their hives in the fight against various bee diseases.
Conclusion
Caring for your honey bee colonies is a crucial aspect of successful beekeeping. By being aware of common threats like chalkbrood, varroa mites, nosema ceranae, deformed wing virus, and small hive beetles, you can take steps to prevent them from damaging your hives.
Regular monitoring and early intervention are essential for maintaining the health and longevity of your honey bees.
Remember to use only safe and effective treatment methods and follow best practices for hive management.
With the right care and attention, your bees will thrive, producing delicious honey and facilitating pollination in your local environment.
