“…The variability found in the morphotypes that we analyzed is consistent with previously obtained results in managed populations in Argentina ( 29 , 47 ). In transition areas between European and Africanized populations, where gene flow is extensive, differences at the mitochondrial, nuclear, and morphometric levels are generally observed because they represent hybrid zones ( 31 , 32 ).…”

“…The analysis of populations that are present in areas of natural hybridization, either through wing morphometry and/or genetics, provides valuable information for the characterization of this process. For instance, examining bee wing morphometry, Porrini et al (29) added evidence of the existence of a latitudinal limit for Africanization in populations of A. mellifera in Buenos Aires, as previously suggested by Abrahamovich et al (30).…”

Beekeepers around the world select bees’ characteristics that facilitate and favor production. In regions where hybridization among lineages is taking place, this selection is a challenge, given that these regions are “natural laboratories”, where the action of evolutionary processes of a population or species occurs in real time. A natural honeybee (Apis mellifera) hybrid zone exists in Argentina between 28° and 35° South, where Africanized (AHB) and European (EHB) populations converge. In this zone, beekeepers use selected genetic resources of European origin mostly, since the local Africanized bees show a higher defensive behavior, which is not desirable for management. Although EHB colonies have many advantages for honey production, they are not fully adapted to the subtropical climate and are susceptible to certain parasitosis such as varroosis. In addition, both AHB and EHB mate in drone congregation areas (DCAs), where males and virgin queens fly to meet, resulting in variability in the desired characteristics. In this study, we explored the degree of hybridization within a DCA and its reference apiary, located in the province of Entre Ríos, by applying two complementary techniques. First, morphotypes with different degrees of hybridization between European and African subspecies were observed in the reference apiary, indicating a high sensitivity of this morphometric approach to detect hybridization in these populations. Second, a genetic analysis revealed haplotypes of both origins for drones in DCAs, with a higher prevalence of European haplotypes, while all the colonies from the reference apiary exhibited European haplotypes. Overall, our results are in line with the strong impact that commercial beekeeping has on the genetics of DCAs. We show how wing morphometry may be used to monitor hybridization between European and African subspecies, a tool that may be evaluated in other regions of the world where hybridization occurs.

“…La estrecha relación con las condiciones ambientales se evidencia por ejemplo en Argentina, cuya extensión territorial abarca diferentes regiones climáticas de norte a sur. Allí, las abejas melíferas africanizadas dominan en las regiones semitropicales del norte, con una disminución gradual de norte a sur, como resultado de la expansión de A. m. scutellata (Porrini et al, 2022). Otro ejemplo lo proveen los reportes de altos niveles de infestación en las regiones frías de Brasil (Moretto et al, 1991).…”

El ectoparásito de Apis mellifera, Varroa destructor, es uno de los principales problemas para la apicultura mundial. La siguiente revisión indaga en investigaciones relacionadas con la parasitosis, con principal hincapié en los estudios llevados a cabo en Latinoamérica. Desde los primeros registros de la parasitosis y hasta la actualidad, se presenta una recopilación de la biología, ecología, virus asociados a Varroa, mecanismos de control con acaricidas de síntesis y resistencia; como así su interacción con los linajes africanos. Finalmente, se integra y discute la relación de los conocimientos en el área con la actividad apícola y los mecanismos actuales de control natural.
