Elucidating the mechanisms by which honey bees process pollen vs. protein supplements are important in the generation of artificial diets needed to sustain managed honeybees. We measured the effects of diet on protein concentration, hypopharyngeal gland development and virus titers in worker honey bees fed either pollen, a protein supplement (MegaBee), or a(More)
The influence of genotype on the conversion of pollen to bee bread and on the protein titers of bees feeding on it was examined using European and Africanized honey bees (EHB and AHB). Bee bread was more acidic than the pollen, and that made by EHB was slightly more acidic than AHB. Protein concentration in bee bread was similar for both subspecies and(More)
Honey bee queens mate with multiple males resulting in high intracolonial genetic diversity among nestmates; a reproductive strategy known as extreme polyandry. Several studies have demonstrated the adaptive significance of extreme polyandry for overall colony performance and colony growth. Colonies that are more genetically diverse collect more pollen than(More)
Honey bees obtain nutrients from pollen they collect and store in the hive as beebread. We developed methods to control the pollen source that bees collect and convert to beebread by placing colonies in a specially constructed enclosed flight area. Methods were developed to analyze the protein and amino acid composition of the pollen and beebread. We also(More)
Most pollination in large-scale agriculture is dependent on managed colonies of a single species, the honey bee Apis mellifera. More than 1 million hives are transported to California each year just to pollinate the almonds, and bees are trucked across the country for various cropping systems. Concerns have been raised about whether such "migratory(More)
Oxidative stress can lead to premature aging symptoms and cause acute mortality at higher doses in a range of organisms. Oxidative stress resistance and longevity are mechanistically and phenotypically linked; considerable variation in oxidative stress resistance exists among and within species and typically covaries with life expectancy. However, it is(More)
