Today, as never before, the beekeeping community is at a crossroads to define the long-term strategy on how to match the challenges evoked by the tiny enemy called Varroa destructor. From the ocean of options for varroa control, two main ideas clash: the pragmatic therapeutic action, with all the chemical arsenal at its disposal, and the idealistic...

The honey bee (Apis mellifera) provides pollination services for many plant species. Over the last decade, major losses of honey bee colonies have been recorded worldwide, mainly as a consequence of diseases, climate changes, agricultural and beekeeping practices. In order to improve the condition of their apiaries, beekeepers must adapt by applyin...

Conference Paper
Full-text available
Different brood interruption methods combined with chemical treatment may successfully remove most V. destructor from the honey bee colonies. Further, the timely brood reduction or break may positively impact nectar intake and is occasionally used by beekeepers during the main spring flow to increase honey production. However, the experience and da...

Article
Full-text available
Honeybees are of great importance because of their role in pollination as well as for hive products. The population of managed colonies fluctuates over time, and recent monitoring reports show different levels of colony losses in many regions and countries. The cause of this kind of loss is a combination of various factors, such as the parasitic mi...

Background With numerous endemic subspecies representing four of its five evolutionary lineages, Europe holds a large fraction of Apis mellifera genetic diversity. This diversity and the natural distribution range have been altered by anthropogenic factors. The conservation of this natural heritage relies on the availability of accurate tools for s...
Article
Full-text available
In the fight against the Varroa destructor mite, selective breeding of honey bee (Apis mellifera L.) populations that are resistant to the parasitic mite stands as a sustainable solution. Selection initiatives indicate that using the suppressed mite reproduction (SMR) trait as a selection criterion is a suitable tool to breed such resistant bee pop...

This article presents managed honey bee colony loss rates over winter 2018/19 resulting from using the standardised COLOSS questionnaire in 35 countries (31 in Europe). In total, 28,629 beekeepers supplying valid loss data wintered 738,233 colonies, and reported 29,912 (4.1%, 95% confidence interval (CI) 4.0–4.1%) colonies with unsolvable queen pro...
Article
Full-text available
Most Varroa induced colony losses occur during the autumn or winter season as a consequence of an elevated Varroa infestation level and an insufficient health status of the adult bees. Even with an initial low Varroa infestation in early spring, critical mite and virus infection levels can be reached before winter if colonies continuously rear broo...
Article
Full-text available
Modern techniques of selective breeding show high potential to improve economically important traits of honey bees. However, breeding may neglect fundamental rules of natural selection. The objective of this study was to analyze the effects of selection and local adaptation on some relevant breeding traits of Apis mellifera carnica. We compared ope...
Article
Full-text available
Background: Genetic improvement of honey bees is more difficult compared to other livestock, due to the very different reproductive behavior. Estimation of breeding values requires specific adjustment and the use of sires in the pedigree is only possible when mating of queens and drones is strictly controlled. In the breeding program of the Nation...
Conference Paper

Most Varroa induced colony losses occur during the winter season in consequence of insufficient health status of the winter bee population. Even with low mite infestation in early spring critical infection levels can be reached until the period of winter bee production if colonies continuously rear brood throughout the whole season. Under natural c...
