Apis mellifera mellifera in eastern Europe — morphometric variation and determination of its range limits
The variability of Apis mellifera mellifera in Eastern Europe was investigated with a morphometric analysis of 136 samples from Poland, Belarus and the Ukraine. Samples from the northern part of thisExpand

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 OctoberExpand

Open-air-nesting honey bees Apis dorsata and Apis laboriosa differ from the cavity-nesting Apis mellifera and Apis cerana in brood hygiene behaviour.
The cavity-nesting Apis mellifera and Apis cerana bees detect, uncap, and remove diseased brood. The hygiene behaviour of open-air-nesting bees Apis dorsata and Apis laboriosa was investigated inExpand
