Article
The haplodiploid sex determination of honey bees and the multiple mating of queens pose challenges in determining the genetic contribution of drones (male honey bees). This is especially important for breeding programs as, for example, when attempting to reinforce traits governing social immunity against pests and diseases. Here, we focused on bree...

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...

The identification of honey bee ( Apis mellifera ) subspecies is often based on the measurements of workers’ fore-wings. The interpretation of the measurements can be difficult because the phenotype of workers is affected by both genetic and environmental factors. Moreover, it is not clear how the phenotype is affected by maternal inheritance. We h...

Neonicotinoids have been among the most frequently used insecticides in the cultivation of several crops and orchards. Till 2012, imidacloprid represented 41.5% of the whole neonicotinoid market and thiamethoxam was the second biggest neonicotinoid, followed by clothianidin. However, almost two years ago, a decision was made by the EC parliament to...
