Semi-natural habitats promote winter survival of wild-living honeybees in an agricultural landscape

Articles

Abstract The diversity of endemic honeybee subspecies and ecotypes is at risk in Europe because modern apiculture promotes only a small number of honeybee strains. A crucial step for the conservation of honeybee diversity is the assessment of the status of remaining wild populations and their limiting factors. Here we present a two-year census of native, wild-living honeybees inhabiting power poles…

Biologically active extracts from different medicinal plants tested as potential additives against bee pathogens

Articles

Abstract Honey bees (Apis mellifera) perform pollination service for many agricultural crops and contribute to the global economy in agriculture and bee products. However, honey bee health is an ongoing concern, as illustrated by persistent local population decline, caused by some severe bee diseases (e.g., nosemosis, AFB, EFB, chalkbrood). Three natural recipes are in development…

Honey botanical origin and honey-specific protein pattern: Characterization of some European honeys

Articles

Abstract Honey adulteration generates low quality products on the market. The study aimed to find a simple, specific and less time-consuming method than standard melissopalynology only, for monitoring honey botanical and geographical origin. In this study 42 honey samples from different sources were examined for their botanical origin by using melissopalynology and their specific protein…

Impact of microorganisms and entomopathogenic nematodes used for plant protection on solitary and social bee pollinators

Articles

Abstract Pollinating bees are stressed by highly variable environmental conditions, malnutrition, parasites and pathogens, but may also by getting in contact with microorganisms or entomopathogenic nematodes that are used to control plant pests and diseases. While foraging for water, food, or nest material social as well as solitary bees have direct contact or even consume…

The Diversity Decline in Wild and Managed Honey Bee Populations Urges for an Integrated Conservation Approach

Articles

Many parts of the globe experience severe losses and fragmentation of habitats, affecting the self-sustainability of pollinator populations. A number of bee species coexist as wild and managed populations. Using honey bees as an example, we argue that several management practices in beekeeping threaten genetic diversity in both wild and managed populations, and drive population…

A Special Issue on COLOSS!

Articles

Bee World, Volume 99, Issue 1 is a special issue on the honey bee research association COLOSS. This issue contains 11 articles written by key members of all COLOSS core projects and task forces. Thanks to some authors institutions and the support of COLOSS all articles are permanently freely available and can be found here.…

Population Structure and Diversity in European Honey Bees (Apis mellifera L.) – An Empirical Comparison of Pool and Individual Whole-Genome Sequencing

Articles

Background: Whole-genome sequencing has become routine for population genetic studies. Sequencing of individuals provides maximal data but is rather expensive and fewer samples can be studied. In contrast, sequencing a pool of samples (pool-seq) can provide sufficient data, while presenting less of an economic challenge. Few studies have compared the two approaches to infer population…

Morphometric and mitochondrial variation of Apis mellifera L. and its relationship with geographical variables in parts of West and Central Africa

Articles

In order to investigate the geographical distribution of morphological and mitochondrial variation of the Western honey bee in West and Central Africa, 175 colonies, sampled from 44 localities (or a subset therefrom), were subjected to geometric morphometric (GM), traditional morphometric (TM) and mitochondrial DNA analyses. The shape of the forewing differed significantly between the three…

Honey Bee Products: Preclinical and Clinical Studies of Their Anti-inflammatory and Immunomodulatory Properties

Articles

Inflammation is a defense process triggered when the body faces assaults from pathogens, toxic substances, microbial infections, or when tissue is damaged. Immune and inflammatory disorders are common pathogenic pathways that lead to the progress of various chronic diseases, such as cancer and diabetes. The overproduction of cytokines, such as interleukin (IL)-1β, IL-6, and tumor…

Joining Forces across Continents: The 1st SOLATINA–COLOSS Conference

Articles

Introduction The first SOLATINA-COLOSS meeting took place virtually on September 22, 2021. The event was set up with the aim of promoting collaboration between the two societies. SoLatInA (SOciedad LATinoamericana de INvestigación en Abejas; www.solatina.org) is the Latin American Society for Bee Research based in Montevideo, Uruguay, founded in 2017 with the objectives of contributing…
