Varying degrees of Apis mellifera ligustica introgression in protected populations of the black honeybee, Apis mellifera mellifera, in northwest Europe
The natural distribution of honeybee subspecies in Europe has been significantly affected by human activities during the last century. Non‐native subspecies of honeybees have been introduced andExpand

Evolutionary interaction networks of insect pathogenic fungi.
Lineages of insect pathogenic fungi are concentrated in three major clades: Hypocreales (several genera), Entomophthoromycota (orders Entomophthorales and Neozygitales), and Onygenales (genusExpand

Relationships of the insect-pathogenic order Entomophthorales (Zygomycota, Fungi) based on phylogenetic analyses of nuclear small subunit ribosomal DNA sequences (SSU rDNA).
We sequenced the nuclear small subunit of ribosomal DNA (SSU rDNA) from seven species within the insect-pathogenic order Entomophthorales. These sequences were aligned with other published SSU rDNAExpand

Miscellaneous standard methods for Apis mellifera research
Summary A variety of methods are used in honey bee research and differ depending on the level at which the research is conducted. On an individual level, the handling of individual honey bees,Expand

Quantifying honey bee mating range and isolation in semi-isolated valleys by DNA microsatellite paternity analysis
Honey bee males and queens mate in mid air and can fly many kilometres on their nuptial flights. The conservation of native honey bees, such as the European black bee (Apis mellifera mellifera),Expand

Standard methods for fungal brood disease research
Summary Chalkbrood and stonebrood are two fungal diseases associated with honey bee brood. Chalkbrood, caused by Ascosphaera apis, is a common and widespread disease that can result in severeExpand

Sick ants become unsociable
Parasites represent a severe threat to social insects, which form high‐density colonies of related individuals, and selection should favour host traits that reduce infection risk. Here, using aExpand

Evidence for emerging parasites and pathogens influencing outbreaks of stress-related diseases like chalkbrood.
In agriculture, honey bees play a critical role as commercial pollinators of crop monocultures which depend on insect pollination. Hence, the demise of honey bee colonies in Europe, USA, and AsiaExpand

Nutritional limitation and resistance to opportunistic Aspergillus parasites in honey bee larvae.
Honey bees are threatened by land use changes which reduce the availability and diversity of pollen and nectar resources. There is concern that poor nutrition may be involved in recent populationExpand
