“…Breeders often declare that their breeding lines belong to a particular subspecies. In order to keep those breeding lines as pure stocks, breeders need to eliminate colonies representing other subspecies (Kauhausen-Keller and Keller 1994). In some cases, beekeepers aim to avoid some subspecies and their hybrids, for example, Africanized honey bees in the American continents (Francoy et al 2008;Sheppard et al 1991Sheppard et al , 1999.…”

-Within the western honey bee (Apis mellifera ), there are more than 20 recognised subspecies. It is well known that these subspecies differ in their wing venation patterns. However, there is a demand for efficient tools to identify honey bee subspecies, ecotypes, populations or hybrids. The aim of this study was to develop a fast and easy identification method based on analysing forewing vein patterns of honey bees by geometric morphometrics. Reference samples for the subspecies were obtained from the Morphometric Bee Data Bank in Oberursel, Germany. These contained 187 honey bee colonies allocated into 25 subspecies from four evolutionary lineages. The identification of evolutionary lineages of honey bees based on forewing venations proved to be highly reliable, which confirms earlier studies. The accuracy of honey bee subspecies identification was less consistent and ranged from 100 to 50% and was particularly low in African honey bees. The obtained identification data were exported to the IdentiFly computer software, which is freely available.honey bee / subspecies discrimination / geometric morphometry / wing morphometry

“…Islands or remote mountain valleys in particular offer excellent opportunities to limit the impact of non-native honey bees. Conservation measures usually include that introduced honey bees and hybrids are replaced by native bees after being identified by discrimination of wing morphology (Ruttner, 1988;Kauhausen-Keller and Keller, 1994) or genetic analyses using microsatellite markers (Neumann et al, 1999a;Scharpenberg et al, 2006;Soland-Reckeweg et al, 2009;Oleksa et al, 2011;Péntek-Zakar et al, 2015).…”

Using Whole-Genome Sequence Information to Foster Conservation Efforts for the European Dark Honey Bee, Apis mellifera mellifera

Pollination is a key ecosystem service for agricultural systems and Western honey bees, Apis mellifera, are the most important managed pollinators. Major losses of managed honey bee colonies reinforced the need to take advantage of locally adapted subspecies and ecotypes to buffer populations against various stressors. However, introductions of non-native honey bees from distant lineages are likely to undermine respective conservation efforts unless reliable and cost effective tools can be used to identify hybridization. The purpose of this study is to characterize current population structure and genetic diversity, and to assess the degree of admixture between native and introduced honey bees. Moreover, we aim to select a reduced number of genetic markers to improve conservation management strategies. We take advantage of recent developments in next-generation sequencing and network-based clustering to investigate conservation efforts for the native European Dark honey bee, A. m. mellifera, which is threatened by introgression in most of its range. We collected whole-genome sequence information from haploid drones of A. m. mellifera, A. m. carnica, and Buckfast sampled throughout Switzerland (N = 81), as well as from four Swiss A. m. mellifera conservation areas (N = 39) and from one conservatory in the French Alps (N = 31). Population structure analyses based upon 3.375 M genome-wide SNPs discerned samples by subspecies and geographic origin (Switzerland or France). Ancestry inference indicated admixed individuals in all of the protected areas, calling for improved management efforts. After testing different subsets of ancestry informative SNPs using three different selection strategies (F ST , PCA-based or at random), as few as 50 SNPs are found to be sufficient to differentiate native from introduced honey bees. Therefore, our data suggests that a low-density SNP panel can be a precise and cost-effective tool to support conservation management efforts for managed pollinators.

“…In addition to colony losses, the black honeybee population as a whole is regularly affected by commercial bee breeding, intensification of queens' import, and transhumance which result in changes of the distribution of the native populations. For example, the black honeybee has been partially, and in some cases totally, replaced by nonnative bees such as A. m. ligustica in Northern Europe (Jensen et al 2005a) and A. m. carnica in Germany (Kauhausen-Keller and Keller 1994;Maul and Hähnle 1994). In other areas such as South-West and North-East of France, black honeybee colonies have been highly introgressed by imported breed stock (Rortais et al 2010).…”

The black honeybee (Apis mellifera mellifera; M lineage) which is affected by widespread colony losses, colony introgression and population shifts within its natural range of distribution, needs proper protection and management planning. The DraI COI-COII test discriminates between and within honeybee lineages (M, C, A and O). With this test, a global assessment of the diversity found in the M lineage (i.e. description of haplotype frequencies, fragment length and size, nucleotide sequences) is made with colonies newly sampled in France and Belgium (n = 3,261 colonies) and previously described in the literature (n = 3,367). A total of 91 M haplotypes were described including 52 new ones. The haplotypes M4 and M4' were the most frequent followed by M17, M7, M6, M19, M8, M17' and by many rare ones. Finally, these data were used to infer hypotheses on the putative origin of the M haplotypic diversity and to determine a protocol for the establishment of protected areas of black honeybee colonies. This protocol is based on the DraI COI-COII test and on case-studies of protected areas of black honeybees from France.
