“…Studies on the population structure of honeybees in areas undergoing Africanization at elevations above 2 500 have not been conducted and Peru gives a unique opportunity to document such a situation. Moreover, the presence of diverse densities of resident European colonies prior to the invasion of African-derived honeybees may also influence the degree of admixture between both bee types depending on numerical competition (Quezada-Euán and Hinsull, 1995;Quezada-Euán and Medina, 1998).…”

Hybridization between European and African-derived honeybee populations (Apis mellifera) at different altitudes in Per�

-The current status of admixture between Apis mellifera of African and European origin was studied in populations from different altitudinal regions of Perú. Worker bees from 7 altitudinal regions were analysed by morphometrics and mtDNA RFLPs. Our results showed that the rates of admixture between African-derived and resident European populations have depended on the altitude of the region. Our finding of hybrid colonies at elevations above 2 500 m supports the hypothesis that climate alone may not restrain the northern limit of the distribution of African-derived honeybees in the Americas. We conclude that introgressive hybridization between African and European derived honeybees best explains the current patterns of distribution of morphotypes and mitotypes across the different regions of Peru.Africanization / hybridization / Apis mellifera / mtDNA / morphometrics / Peru

“…Until the late 1980s, the Neotropical Yucatan Peninsula of Mexico contained an extremely high density (estimated at 17 colonies/km 2 , Quezada-Euán and Hinsull 1995;QuezadaEuán et al 1996) of managed colonies. These colonies were primarily derived from southeastern European subspecies (A. m. ligustica and A. m. caucasica) and smaller numbers of northern and western subspecies (A. m. mellifera and A. m. iberica;Clarke et al 2001).…”

The Africanization of Honeybees (Apis Mellifera L.) of the Yucatan: A Study of a Massive Hybridization Event Across Time

Abstract. Until recently, African and European subspecies of the honeybee (Apis mellifera L.) had been geographically separated for around 10,000 years. However, human-assisted introductions have caused the mixing of large populations of African and European subspecies in South and Central America, permitting an unprecedented opportunity to study a large-scale hybridization event using molecular analyses. We obtained reference populations from Europe, Africa, and South America and used these to provide baseline information for a microsatellite and mitochondrial analysis of the process of Africanization of the bees of the Yucatan Peninsula, Mexico. The genetic structure of the Yucatecan population has changed dramatically over time. The pre-Africanized Yucatecan population (1985) comprised bees that were most similar to samples from southeastern Europe and northern and western Europe. Three years after the arrival of Africanized bees (1989), substantial paternal gene flow had occurred from feral Africanized drones into the resident European population, but maternal gene flow from the invading Africanized population into the local population was negligible. However by 1998, there was a radical shift with both African nuclear alleles (65%) and Africanderived mitochondria (61%) dominating the genomes of domestic colonies. We suggest that although European mitochondria may eventually be driven to extinction in the feral population, stable introgression of European nuclear alleles has occurred.

“…[24,26]. Il n'est pourtant pas clair que la forte densité d'abeilles européennes élevées au Yucatan ait eu une influence génétique sur la population sauvage récemment établie et censée être principalement africanisée [22,29]. Cet article présente les résultats d'une étude à long terme sur le statut génétique des abeilles des colonies sauvages du Yucatan réalisée à l'aide de l'analyse combinée des caractères morphométriques, allozymiques et de l'ADN mitochondrial.…”

“…In a preliminary study, Quezada-Euán and Hinsull [22] found a diverse arrangement of morphotype/mitotype associations, which suggested that a European gene flow occurred in the feral population during the early stages of Africanization, probably as a consequence of the high densities of European resident-managed colonies. These results are in contrast with what has been found in other areas of the neotropics [8,35].…”
