“…Our findings are similar to research of Louveaux et al (1966), who transposed bees originating in areas with a spring or summer peak, and demonstrated that the bees were unadapted to the new environment, which was shown by worse performances (weight of hive, pollen harvest, extent of the brood-comb) than those of the indigenous colonies. They found that change of the queen had the same effect.…”

SummaryThe objective of this study was to compare the colony development cycle (unsealed and sealed worker brood, drone brood, pollen and colony strength) of two Apis mellifera carnica subpopulations in two distinct environments (alpine and continental). At each test location were two sub groups of 12 colonies headed by naturally mated sister queens from either the Institute of Apiculture Lunz am See, Austria (AT) or from the Faculty of Agriculture University of Zagreb, Croatia (HR). Colony development was monitored every 14 days. The HR genotype, adapted to a continental climate, had faster spring brood development in both environments. During spring and early summer the AT genotype maintained the number of sealed brood cells at a constant level in the more favourable conditions, although the amount of unsealed brood reached its maximum in early June. The environment influenced colony development, food stores and colony strength. Interaction between genotype and environment did not affect the number of unsealed brood cells, but the difference was statistically significant for the number of sealed brood cells. The study indicated the presence of a number of genotype and environment interactions between the two honey bee genotypes and their colony traits. Desarrollo de colonias de dos genotipos Carniola (Apis mellifera carnica) en relación con el medio ambiente ResumenEl objetivo de este estudio fue comparar el ciclo de desarrollo de la colonia (cría de obreras operculada y no operculada, cría de zánganos, el polen y la fuerza de colonias) de dos subpoblaciones de Apis mellifera carnica en dos ambientes distintos (alpino y continental). En cada lugar de prueba se pusieron dos subgrupos de 12 colonias encabezadas por reinas hermanas fecundadas naturalmente, ya sea del Instituto de Apicultura Lunz am See, Austria (AT) o de la Facultad de Agricultura de la Universidad de Zagreb, Croacia (HR). El desarrollo de las colonias se controló cada 14 días. El genotipo HR, adaptado a un clima continental, tuvo un desarrollo más rápido de la cría en primavera en ambos ambientes. Durante la primavera y principios del verano el genotipo AT mantuvo el número de celdas de cría operculadas a un nivel constante en las condiciones más favorables, aunque la cantidad de cría abierta alcanzó su máximo a principios de junio. El ambiente influyó en el desarrollo de las colonias, la reserva de alimentos y la fuerza de la colonia. La interacción entre el genotipo y el medio ambiente no afectó el número de celdas de cría sin opercular, pero la diferencia fue estadísticamente significativa para el número de celdas de cría operculada. El estudio indicó la presencia de una serie de interacciones del genotipo con el medio ambiente entre los dos genotipos de abejas y los caracteres de sus colonias.Keywords: Apis mellifera carnica, genotype x environment interactions, colony development, local adaptation 262 Drazic et al.

“…However, pollen is collected on the basis of colony needs, with small quantities kept as a reserve (Dreller et al, 1999). In our experiment, the local genotype had higher pollen reserve in most measurements, which is similar to findings of Louveaux et al (1966).…”

“…In France one of the country's four identified ecotypes of A. m. mellifera occurs in the Landes region (Louveaux et al, 1966), characterized by an unusual brood cycle adapted to the late season blooming of ling heather, Calluna vulgaris. This brood cycle was found in almost 50% of the colonies analyzed by Strange et al (2007) and, therefore, several morphological and molecular approaches have been used to distinguish this ecotype from introduced Buckfast hybrids (Strange et al, 2008).…”

-Europe harbours several endemic honeybee (Apis mellifera) subspecies. Yet the distribution of these subspecies is nowadays also much influenced by beekeeping activities. Large scale migratory beekeeping and trade in queens, coupled with the promiscuous mating system of honeybees, have exposed native European honeybees to increasing introgressive hybridization with managed non-native subspecies, which may lead to the loss of valuable combinations of traits shaped by natural selection. Other threats to European honeybees are factors that have caused a progressive decline in A. mellifera throughout the world in recent years, leading to large economic losses and jeopardizing ecosystem functioning. We review the biodiversity of European honeybees and summarize the management and conservation strategies employed by different countries. A comprehensive picture of the beekeeping industry in Europe is also provided. Finally we evaluate the potential threats affecting the biodiversity of European honeybee populations and provide some perspectives for future research.Apis mellifera / subspecies / biogeography / conservation / Europe / beekeeping

“…On a constaté, grâce à ce type de recherches que des populations locales d'abeilles se forment et qu'elles présentent une nette adaptation au milieu. Ainsi, alors que dans le bassin parisien le cycle biologique annuel des colonies d'abeilles ne présente qu'un seul sommet en fin du mois de juin, celui des abeilles des Landes est à deux sommets, bien adapté à la floraison estivale de la callune (Louveaux et al, 1966).…”

Résumé.-Dans les relations entre les abeilles et les plantes la récolte du pollen constitue l'élément essentiel. Elle est étudiée du point de vue quant~atif et du point de vue qualitatif. Les choix opérés par les abeilles au sein d'une flore sont sous la dépendance de stimuli sensoriels ainsi que de facteurs trophiques et de facteurs génétiques. L'étude du comportement de récolte du pollen est liée à celle de la pollinisation. L'abeille est utilisable comme indicateur biologique par l'intermédiaire des pollens qu'elle récolte.L'analyse pollinique des miels est une méthode utilisable par la recherche fondamentale. Elle sert également à des contrôles de qualité et d'origine dans l'agroalimentaire. Des efforts restent à faire pour adapter ses techniques à ses divers objectifs.Summary.-Among the relations between bees and plants pollen collection is the most important feature and is studied from a quant~ative and also qualitative point of view. The choices made by bees among a flora depends on sensorial stimuli, trophic factors and also genetic factors. Study of pollen collection behaviour is connected with pollination. The honey bee is su~able as biological indicator through the pollen she gathers. Pollen analysis of honey is a suitable method for fundamental research but is also used for quality and origin contrais in food industry. Efforts have ta be made ta adapt ils technical processes to ils various purposes.
