The German bee monitoring project: a long term study to understand periodically high winter losses of honey bee colonies
The Western honey bee, Apis mellifera, is the most important animal pollinator in agriculture worldwide providing more than 90% of the commercial pollination services. Due to the development in… Expand
OXALIC ACID TREATMENTS FOR VARROA CONTROL (A REVIEW)
Oxalic acid (OA) is one of the most common natural acaricides used against varroa throughout Europe. Its activity is well known since the middle 1980s at least, due to experiments performed mainly in… Expand
Breeding for resistance to Varroa destructor in Europe
The rich variety of native honeybee subspecies and ecotypes in Europe offers a good genetic resource for selection towards Varroa resistance. There are some examples of mite resistance that have… Expand
Standard methods for rearing and selection of Apis mellifera queens
Summary Here we cover a wide range of methods currently in use and recommended in modern queen rearing, selection and breeding. The recommendations are meant to equally serve as standards for both… Expand
Conserving diversity and vitality for honey bee breeding
Summary Beekeepers in Europe, North America and other parts of the world have repeatedly been afflicted by elevated and sometimes unexplained colony losses. Multiple factors have been considered in… Expand

A strong immune defense is vital for honey bee health and colony survival. This defense can be weakened by environmental factors that may render honey bees more vulnerable to parasites and pathogens.… Expand
The influence of genetic origin and its interaction with environmental effects on the survival of Apis mellifera L. colonies in Europe
Summary The survival and performance of 597 honey bee colonies, representing five subspecies and 16 different genotypes, were comparatively studied in 20 apiaries across Europe. Started in October… Expand
Variance and heritability of the capped developmental stage in European Apis mellifera L. and its correlation with increased Varroa jacobsoni Oud. infestation.
SummaryA time-saving method for determining the duration of the capped stage (sealed brood) of large numbers of colonies is described. The results of 112 colonies covering 22 different origins and… Expand
