Abstract Background Varroa mite, destructor Anderson and Trueman (Parasitiformes: Varroidae), is an ectoparasitic mite of the honey bee, Apis mellifera L. (Hymenoptera: Apidae), with a great economic importance. It major deadlock apiculture development all over world. Results This work aimed to assess effect bee house dark on numbers white card board sheets, worker broods, alive bees during spr...

The ectoparasitic mite, Varroa destructor, shifted host from the eastern honeybee, Apis cerana, to the western honeybee, Apis mellifera. Whereas the original host survives infestations by this parasite, they are lethal to colonies of its new host. Here, we investigated a population of A. cerana naturally infested by the V. destructor Korea haplotype that gave rise to the globally invasive mite ...

Honey bee (Apis mellifera L.) colonies bred for hygienic behavior were tested in a large Þeld trial to determine if they were able to resist the parasitic mite Varroa destructor better than unselected colonies of “Starline” stock. Colonies bred for hygienic behavior are able to detect, uncap, and remove experimentally infested brood from the nest, although the extent to which the behavior actua...

The ectoparasitic mite Varroa destructor and honey bee pathogenic viruses have been implicated in the recent demise of honey bee colonies. Several studies have shown that the combination of V. destructor and deformed wing virus (DWV) poses an especially serious threat to honey bee health. Mites transmitting virulent forms of DWV may cause fatal DWV infections in the developing bee, while pupae ...

The number of managed honey bee colonies has considerably decreased in many developed countries in recent years and ectoparasitic mites are considered as major threats to honey bee colonies and health. However, their general biology remains poorly understood. We sequenced the genome of Tropilaelaps mercedesae, the prevalent ectoparasitic mite infesting honey bees in Asia, and predicted 15 190 p...

For three years, about 1,500 hives were surveyed for varroa mites following feeding tests using cupric gluconate and cupric lactate in sucrose syrup. Three to five litres per hive of 0 to 2.8g of copper metal per litre of sucrose syrup were given in spring and/or summer. Bee and mite mortalities were recorded up to four years without significant toxicity being noted for honeybees. By contrast, ...

Multiple infections of managed honeybee, Apis mellifera, colonies are inevitable due to the ubiquitous ectoparasitic mite Varroa destructor and might be an underlying cause of winter losses. Here we investigated the role of adult small hive beetles, Aethina tumida, alone and in combination with V. destructor for winter losses and for infections with the microsporidian endoparasite Nosema cerana...
