PARASITIC
MITE

 

 

Parasitic mites are a serious threat to the health of honeybee colonies worldwide. There are several types of mites that can parasitize honeybees, including Varroa mites, Tropilaelaps mites, and Acarapis woodi mites. These mites can cause significant damage to bees, and if left untreated, can lead to the collapse of entire colonies. In this article, we will discuss the symptoms, treatments, and prevention measures for parasitic mites in honeybee colonies.

 

Symptoms of parasitic mites in honeybee colonies:

​

• Varroa mites: Varroa mites are the most common parasitic mites found in honeybee colonies. The symptoms of Varroa infestation include deformed wings, reduced lifespan of worker bees, and a decline in overall colony health. Severe infestations can lead to the death of entire colonies.

• Tropilaelaps mites: Tropilaelaps mites are a lesser-known parasitic mite that can cause significant damage to honeybee colonies. The symptoms of Tropilaelaps infestation include stunted brood development, reduced lifespan of worker bees, and an overall decline in colony health.

• Acarapis woodi mites: Acarapis woodi mites are a type of mite that primarily infest the tracheae of adult honeybees. The symptoms of infestation include a rasping sound when bees breathe, reduced brood development, and an overall decline in colony health.

 

Treatments for parasitic mites in honeybee colonies:

​

• Varroa mites: The most effective treatment for Varroa mites is chemical treatment with acaricides. There are several acaricides available on the market, and beekeepers should carefully follow the instructions for use to avoid harming their bees. Natural treatments, such as drone brood removal or powdered sugar dusting, can also be effective in reducing Varroa mite populations.

• Tropilaelaps mites: Chemical treatments for Tropilaelaps mites are limited, and beekeepers may need to rely on natural treatments such as drone brood removal or the use of predatory mites to control infestations.

• Acarapis woodi mites: Acarapis woodi mites are difficult to treat, and infected colonies are often destroyed to prevent the spread of the mites to other colonies.

​

Prevention measures for parasitic mites in honeybee colonies:

​

• Regular hive inspections: Beekeepers should regularly inspect their hives for signs of mite infestations. Early detection and treatment can prevent the spread of mites to other colonies.

• Good hive management: Proper hive management, including the removal of old comb and the use of screened bottom boards, can help reduce mite populations in honeybee colonies.

• Genetic selection: Beekeepers can select for honeybees that have natural resistance to parasitic mites. These bees are bred for their ability to groom and remove mites from each other and can help reduce mite populations in a colony.

 

Parasitic mites are a serious threat to honeybee colonies worldwide, and beekeepers should take steps to prevent and treat infestations. Regular hive inspections, good hive management, and genetic selection can all help reduce mite populations in honeybee colonies. Chemical and natural treatments are available for Varroa and Tropilaelaps mites, while colonies infected with Acarapis woodi mites are often destroyed to prevent the spread of the mites to other colonies.
