Beekeeping

The concerns for the effects of honey bee declines have spurred several large-scale surveys of honey bee health around the world
to evaluate potential drivers of colony losses. United States and Europe already have well developed honey bee surveys, however,
no large-scale survey has yet been developed in South America. In this paper, we present such an initiative of a national survey of
honey bee health in Argentina, which hosts the largest population of managed honey bee colonies in South America. It is also one
of the top honey-producing countries in the world. We developed a volunteer-based survey using a standardized questionnaire
and distributed it to a national network of beekeepers. The rapid mobilization and support from beekeepers shows an interest
in and a need for this type of national survey. We call for help from the readers of American Bee Journal to improve the dissemination of the questionnaire among potential interested parties in Argentina. We provide methods and recommendations to help the development of national surveys of honey bee health and also encourage such initiatives in other South American countries.

The present experiment was carried out to study biodiversity,
frequency and effect of pollinators in the production of pods and grains in soybean (Glycine max L. Merrill), var. ‘Mon Soy 3329’. Two treatments were used (covered with clarite area and open area) so that bugs could visit them freely. Among the bugs, which come to visit soybean flowers, Apis mellifera species was the most frequent visitor (84.93%), followed by Lepidoptera (5.75%), Diabrotica speciosa (2.74%), Lagria villosa (Coleoptera: Lagriidae – 2.47%), wasps (Hymenoptera: Vespidae – 2.47%), Trigona sp. (Hymenoptera: Apidae – 0.82%) and others (0.82%). The number of pods per plant and number of seeds per plant did not show difference in covered and open areas, however, the total weight of seeds per plant and the weight of each seed were the greatest ones (43.68%) in open area (23.69g) than covered one (16.49g), with an increase of 44.45% and 50.42%, respectively, in relation to the open area without honeybees. In open area, the number of pods with one seed was 180% bigger (p <0.05) and the pods with three seeds were 31.93% smaller (p< 0.05) when compared with plants in covered area. The soybeans flowers are attractive to Africanized honeybees that contribute with this plant pollination.

Aktuell wird viel über das weltweite Bienensterben diskutiert: Andreas Heidinger und Christian Kuhn bringen mit ihrem Buch mögliche Lösungsansätze in die Debatte ein. Sie stellen ein neues, den modernen imkerlichen Ansprüchen genügendes Beutensystem vor, das sich an der natürlichen Lebensweise der Bienen orientiert und ihnen so ein friedliches, gesundes Leben ermöglicht: Die Bienenkugel!

Erfahren Sie, welche Beobachtungen zu diesem runden Beutensystem geführt haben und welche Vorteile es im Gegensatz zu den herkömmlichen rechteckigen Kästen mit sich bringt. Lernen Sie, wie die Bienenkugel aufgebaut ist und wie man damit imkert.

Sowohl für Neuimker als auch für erfahrene Experten geeignet.

Andreas Heidinger hat 2012 die „Bienenkugel“ entwickelt, um den Bienen ein Leben wie in der Baumhöhle zu ermöglichen.

Dr. Christian Kuhn ist Lehrer, Hochschullehrer und hält Vorträge zur Beziehung von Biene und Mensch.

L’apicoltura è un’attività diffusa in quasi tutti i Paesi del mondo con caratteristiche molto eterogenee.
Il poster riporta i risultati economici di un piccolo allevamento apistico di media montagna caratterizzato da produzioni contenute, ma di notevole qualità, condotto con un livello limitato di meccanizzazione, congruente con la tipologia produttiva hobbistica.

RÉSUMÉ La promotion de la culture de l'anacarde et de son association à l'élevage des abeilles représente de nos jours une opportunité dans le cadre de la diversification des filières tout en misant sur un meilleur rendement. L'étude vise à établir l'état des lieux de la caractérisation moléculaire et éthologique de l'abeille Apis mellifera adansonii et de son parasite Varroa destructor, dans l'habitat de l'anacardier au Bénin. Après une brève description du système agro-forestier basé sur l'anacardier et des abeilles mellifères pollinisatrices des cultures, les approches morphométriques et moléculaires qui sont les éléments d'identification de la lignée, des écotypes et de la race des abeilles ont été énumérées. Il ressort de l'analyse de ces travaux que :-les études morphométriques ont été effectuées sur les abeilles dans chacun des continents (Afrique, Europe, Amériques, Asie etc.) ;-de nombreuses études scientifiques existent sur la diversité des populations d'abeilles en Europe, aux Amériques et en Asie contrairement en Afrique ou une seule étude a été effectuée sur la diversité génétique des populations d'abeilles ;-au Bénin, les travaux sur la diversité génétique des d'abeilles et l'étude de leur comportement n'existent pas à notre connaissance. Pourtant, des études en génétique des populations sur les abeilles mellifères devraient être faites au Bénin pour la préservation de la biodiversité des abeilles. De telles études sont importantes dans l'habitat de l'anacardier au Bénin pour une promotion de l'association de l'apiculture à l'agriculture et un meilleur rendement de la production d'anacarde au Bénin. ABSTRACT Summary literature on molecular and ethological characterization of the bee (Apis mellifera) and its parasite Varroa destructor in the cashew tree's habitat in Benin. Promoting the cashew tree and associating it with beekeeping is nowadays an opportunity for diversifying industries while focusing on improved productivity. The purpose of this study is to take stock of the molecular and ethological characterization of the bee Apis mellifera adansonii and its parasite Varroa destructor in the cashew tree habitat in Benin. After an overview of the agroforestry system based on the cashew tree and bees pollinating crops, morphometric and molecular approaches that are the identifiers of line, ecotypes and the breed of bees were listed. From the analysis of these researches, the following conclusions can be safely drawn:-morphometric studies were conducted on bees on each continent (Africa, Europe, Asia etc…);-Kelomey et al. 368 many scientific studies are available on the diversity of the bee populations in Europe, America and Asia unlike Africa where only one worked on the genetic diversity of the bee populations;-researches on the genetic diversity of bees and the behavioral study of them are not available in Benin. Yet, studies of honeybees in population genetics should be conducted in Benin so as to preserve the biodiversity of bees. Such studies are significant in the habitat of the cashew tree in Benin for promoting beekeeping association with agriculture and for an improved performance of the cashew sector in Benin.
