How do you spot chalkbrood?

Symptoms

1. CHALKY-WHITE COVERING ON LARVAE.
2. GRAY OR BLACK FUNGUS ON LATER-STAGE INFECTION.
3. MUMMIFIED LARVAE.
4. MAINTAIN CONTROLLED, SANITARY BEE HUSBANDRY.
5. KEEP HIVES WARM AND DRY (OR TEMPERATURECONTROLLED IN EXTREME CASES)

7. VERIFY CHALKY WHITE/GRAY/BLACK GROWTH ON BROOD.

How do you treat a chalkbrood in a bee colony?

Apiguard or a thymol based treatment is active against chalkbrood. Vitafeed Green contains thymol and also works against chalkbrood. Beevital Chalkbrood is another product available for treating chalkbrood. Increased ventilation in the hive will help prevent chalkbrood.

What causes chalkbrood in beehives?

Chalkbrood disease is caused by the fungus Ascosphaera apis. The fungus rarely kills infected colonies but can weaken it and lead to reduced honey yields and susceptibility to other bee pests and diseases. Young infected larvae do not usually show signs of disease but will die upon being sealed in their cells as pupae.

What is chalkbrood disease in bees?

What is chalkbrood disease? Chalkbrood disease is caused by the fungus Ascosphaera apis. The fungus produces spores which are swallowed by honey bee larvae when they are fed by nurse bees. The spores germinate in the honey bee’s gut and ultimately cause the larvae to die of starvation.

How does chalkbrood affect a honey bee colony?

Chalkbrood is frequently seen in late spring when colonies are expanding rapidly, the weather is still cool, and there may not be enough nurse bees to keep the brood warm. It often disappears spontaneously as summer temperatures rise. Although chalkbrood rarely destroys a colony, it can weaken a colony and cause reduced honey production.

How to remove chalkbrood from mason bee cocoons?

What to do if you have Chalkbrood disease in bees?

Because spores spread so easily, do not use tools that were used in an infected hive. Clean them thoroughly with alcohol or a propane torch before reusing them. Also, avoid transferring combs from an infected hive to a clean hive, and use robbing screens to discourage drifting bees.
