TRACHEAL MITES

 

 

Tracheal mites are tiny external parasites that can infest honeybees and cause significant damage to their respiratory systems. These mites feed on the hemolymph (bee blood) and tissue of the tracheal tubes in bees, which can cause blockages and lead to respiratory problems. Infestations of tracheal mites can weaken or kill honeybee colonies, and therefore, it is important for beekeepers to be aware of the symptoms, treatments, and prevention measures for this condition.

​

Symptoms of Tracheal Mites in Honeybees: Tracheal mites are difficult to detect because they live inside the tracheal tubes of bees, where they feed and lay eggs. However, there are some signs that may indicate a tracheal mite infestation, such as:

​

• Bees with short, ragged wings, and missing or deformed legs

• Bees that have trouble flying and have a shorter lifespan than healthy bees

• Bees that crawl instead of flying

• A higher than normal number of dead bees in front of the hive

• An overall decline in the health of the colony

​

These symptoms may not be specific to tracheal mites, but it is important to monitor the hive for any unusual behaviour and contact a local beekeeping association or veterinary professional if there are concerns.

​

Treatments for Tracheal Mites in Honeybees: There are several treatments for tracheal mites in honeybees, including:

​

• Essential oils: Some essential oils, such as thyme and eucalyptus oil, have been found to be effective against tracheal mites. These oils can be added to sugar syrup or applied as a spray to the bees.

• Formic acid: Formic acid is a natural substance found in honey, and it can also be used to treat tracheal mites. However, it should be used with caution as it can be toxic to bees and humans if not handled correctly.

• Oxalic acid: Oxalic acid is a chemical compound that is effective against tracheal mites when applied in the right concentrations. It is usually applied as a vapor or dribbled onto the bees.

• Powdered sugar: Powdered sugar can be used to dust the bees and remove the mites. This method is not always effective, but it is a non-toxic and inexpensive option.

​

Prevention Measures for Tracheal Mites in Honeybees: Prevention is always better than treatment, and there are several measures beekeepers can take to prevent tracheal mites in their hives:

​

• Regular hive inspections: Regular hive inspections can help detect early signs of tracheal mites and prevent an infestation from spreading.

• Re-queening: Re-queening with a new queen bee can help prevent tracheal mites as the new queen may be more resistant to the mites.

• Good hive hygiene: Keeping the hive clean and free of debris and waste can help prevent tracheal mites and other parasites from taking hold.

• Minimizing stress: Minimizing stress factors, such as overcrowding or sudden changes in hive conditions, can help prevent tracheal mites and other health issues in honeybees.

​

Tracheal mites can be a serious threat to honeybee colonies, and beekeepers should be aware of the symptoms, treatments, and prevention measures for this condition. Early detection and treatment can help prevent an infestation from spreading and potentially damaging the hive.
