Agriculture Ministry Urges Immediate Action as Destructive Pest Spreads Across Local Apiaries.
The Ministry of Agriculture and Livestock (MAL) is urging bee farmers to remain vigilant due to a widespread incursion of the Varroa mite (Varroa destructor), a serious threat to honey bee colonies worldwide, now confirmed in Honiara.
First detected in North Carolina in 1990, this external parasitic mite is one of the most destructive pests affecting honey bees. A significant infestation can lead to the collapse of entire colonies.
Dr. Cooper, a bee expert from Southern Cross University in Australia, along with MAL Livestock officers, conducted soap wash tests in response to reports from Honiara bee farmers between May and June 2023. Beekeepers had observed a decline in both bee populations and honey production, raising concerns about the health of their hives. The tests confirmed the presence of the Varroa mite in apiaries around Honiara, indicating a widespread infestation that requires immediate attention.
In light of the potential damage to the bee industry, the MAL Livestock Department advises all bee farmers to avoid the transfer of used bee materials from Honiara or surrounding areas to other locations. Sharing used beekeeping equipment with other farmers is strongly discouraged, as it can spread the infestation. Regular monitoring of hives is crucial; any unusual behavior in the beehives should prompt a thorough inspection of the bee boxes. Farmers are encouraged to observe their beehives daily, both morning and afternoon, to detect mite infestations early. It is recommended that farmers seek guidance from the MAL Livestock Team on control measures and best practices.
The Varroa mite is an external parasite that attacks both adult bees and developing larvae. Adult mites are reddish-brown, oval-shaped, and about 0.06 inches wide, approximately the size of a pinhead. The female mite enters the cell of a developing bee larva and lays up to six eggs. Feeding by the developing mites can lead to the death or deformity of the larvae. While male mites die within the cell, adult female mites attach to adult bees, feeding on their hemolymph and continuing the cycle. Mites prefer drone larvae but will also infest worker larvae, ultimately threatening the entire colony if left unmanaged.
In addition to direct harm, Varroa mites pose an indirect threat by serving as vectors for viruses that can fatally infect bees. The impact on the bees’ immune systems can lead to Parasitic Mite Syndrome (PMS), which can decimate colonies within months.
