Evaluation of Traits for the Selection of Apis Mellifera for Resistance against Varroa Destructor

Insects, 2020
Infestation with Varroa destructor is a serious cause of bee colony (Apis mellifera) losses on a global level. However, the presence of untreated survivor populations in many different regions supports the idea that selection for resistance can be ...

Análisis de introgresión en Apis mellifera iberiensis y Apis mellifera mellifera usando polimorfismos de nucleótidos simples (SNPs) [PDF]

, 2014
Diferentes estudios han agrupado las subespecies de A. mellifera en cuatro linajes evolutivos basados sobre marcadores morfométricos, ecológicos, microsatélites y mtDNA: Africano (A), Medio Oriente (O), Este y Centro de Europa (C), Norte y Oeste de ...

Pathogen and Hemocyte Dynamics in Three Apiaries Across a Bee Season

Transboundary and Emerging Diseases, Volume 2025, Issue 1, 2025.
Honey bees are dying due to a disease complex consisting of viruses, parasites, chemicals, nutritional deficiencies, and management problems. In the present study, pathogens and hemocytes were analyzed in honey bee hemolymph samples using third‐generation sequencing and flow cytometry in three apiaries over a honey bee season. Using nanopore sequencing,

Honeybee rebel workers invest less in risky foraging than normal workers [PDF]

, 2018
In eusocial insect colonies, workers have individual preferences for performing particular tasks. Previous research suggests that these preferences might be associated with worker reproductive potential; however, different studies have yielded ...

Accurate Detection of scutellata‐Hybrids (Africanized Bees) Using a SNP‐Based Diagnostic Assay

Ecology and Evolution, Volume 14, Issue 11, November 2024.
Africanized bees continue to pose a threat to the apiculture industry in North America. Our genetic assay when coupled with machine learning demonstrates high accuracy in correctly classifying target samples. ABSTRACT Hybrid populations of Africanized honey bees (scutellata‐hybrids), notable for their defensive behaviour, have spread rapidly throughout

From consumption to excretion: Lithium concentrations in honey bees (Apis mellifera) after lithium chloride application and time‐dependent effects on Varroa destructor

Pest Management Science, Volume 80, Issue 11, Page 5799-5808, November 2024.
Feeding caged bees with 50 mm LiCl results in rapid mite mortality. Bee metabolism leads to swift excretion, and only traces of lithium can be found in the hypopharyngeal glands of nurse bees. Abstract BACKGROUND Owing to its systemic mode‐of‐action and ease of application, lithium chloride (LiCl) is an ideal varroacide for the control of Varroa ...

Organic farming and annual flower strips reduce parasite prevalence in honeybees and boost colony growth in agricultural landscapes

Journal of Applied Ecology, Volume 61, Issue 9, Page 2146-2156, September 2024.
Landscape features can affect pollinators directly through the provision of food resources and indirectly through modulation of parasite prevalence. To promote honeybee colony health in agro‐ecosystems, our results suggest that organic agriculture and annual flower strips should be prioritized conservation measures. Landscape management should consider

Opredelitev populacij kranjske čebele (Apis mellifera carnica Pollman) na osnovi analize mitohondrijske DNK

Acta Agriculturae Slovenica, 2002
Kranjska čebela (Apis mellifera carnica Pollman 1879) je glede na morfologijo uvrščena v jugovzhodno evropsko skupino čebel in je druga najbolj razširjena podvrsta čebel na svetu. Glede na morfologijo pa tudi glede na razlike v mitohondrijski DNK (mtDNK),

The cost of promiscuity: sexual transmission of Nosema microsporidian parasites in polyandrous honey bees [PDF]

, 2015
Multiple mating (and insemination) by females with different males, polyandry, is widespread across animals, due to material and/or genetic benefits for females.
