Genetic diversity and differentiation among insular honey bee populations in the southwest Indian Ocean likely reflect old geographical isolation and modern introductions With globalization the Western honey bee has become a nearly cosmopolitan species, but it was originally restricted to the...

Population Genetics of Nosema apis and Nosema ceranae: One Host (Apis mellifera) and Two Different Histories Two microsporidians are known to infect honey bees: Nosema apis and Nosema ceranae. Whereas population genetics data for the latter have been released in the last few years, such...

Genetics, Synergists, and Age Affect Insecticide Sensitivity of the Honey Bee, Apis mellifera The number of honey bee colonies in the United States has declined to half of its peak level in the 1940s, and colonies lost over the winter have reached levels that are becoming economically unstable...

Microsatellite Analysis of Museum Specimens Reveals Historical Differences in Genetic Diversity between Declining and More Stable Bombus Species Worldwide most pollinators, e.g. bumblebees, are undergoing global declines. Loss of genetic diversity can play an essential role in these observed...

Extreme Recombination Frequencies Shape Genome Variation and Evolution in the Honeybee, Apis mellifera Meiotic recombination is a fundamental cellular process, with important consequences for evolution and genome integrity. However, we know little about how recombination rates vary across the...

No Genetic Tradeoffs between Hygienic Behavior and Individual Innate Immunity in the Honey Bee, Apis mellifera Many animals have individual and social mechanisms for combating pathogens. Animals may exhibit short-term physiological tradeoffs between social and individual immunity because the...

Evidence for intra-colonial genetic variance in resistance to American foulbrood of honey bees ( Apis mellifera): further support for the parasite/pathogen hypothesis for the evolution of polyandry. Palmer KA1, Oldroyd BP. Author information Abstract Explanations for the evolution of...

A Cell Line Resource Derived from Honey Bee (Apis mellifera) Embryonic Tissues We have developed a method incorporating established insect cell culture techniques that supports sustained growth of honey bee cells in vitro. We used honey bee eggs mid to late in their embryogenesis to establish...

Lack of Variation at Phosphoglucose Isomerase (Pgi) in Bumblebees: Implications for Conservation Genetics Studies A goal of modern conservation genetics is to address the extent to which adaptive variation, especially for loci where polymorphism should be maintained, is affected by the forces...

Effect of Stacked Insecticidal Cry Proteins from Maize Pollen on Nurse Bees (Apis mellifera carnica) and Their Gut Bacteria The objective of this study was to analyze the response of nurse bees and their gut bacteria to pollen from Bt maize expressing three different insecticidal Cry proteins...

Multiple Mating But Not Recombination Causes Quantitative Increase in Offspring Genetic Diversity for Varying Genetic Architectures Experimental studies that compared genetically diverse colonies produced by multiply-mated queens to genetically more homogeneous colonies that were produced by...
