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

open access: yesEcology 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

open access: yesPest 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 ...

Wachse der Honigbiene Apis mellifera carnica Pollm. [PDF]

open access: yes, 2000
Quantitative chemical analyses of comb waxes with different age and cuticular waxes of different castes and sexes with gas chromatography, mass spectrometry and FTIR-spectrometry showed significant chemical differences in the aliphatic hydrocarbons and differences in the physical properties of the waxes.

Standard methods for Apis mellifera anatomy and dissection [PDF]

open access: yes, 2013
An understanding of the anatomy and functions of internal and external structures is fundamental to many studies on the honey bee Apis mellifera. Similarly, proficiency in dissection techniques is vital for many more complex procedures.

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

open access: yesJournal 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

open access: yesActa 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),
