Microbiological investigation study for Apis mellifera yemenitica and Apis mellifera carnica bee venoms on selected bacterial strains. [PDF]

Braz J Microbiol, 2022
Bees are one of the ancient and the most social insects worldwide. They are of great economic and medical importance. Bee venom (BV) has many therapeutic effects and has been used since ancient times for the treatment of many diseases. The present study aimed to evaluate and compare the antibacterial effect of BV from two different bee subspecies Apis ...

Enantioselectivity of odor perception in honeybees (Apis mellifera carnica). [PDF]

Behavioral Neuroscience, 2001
The authors tested the ability of 60 free-flying honeybees (Apis mellifera carnica) to discriminate a conditioning odor from an array of 26 simultaneously presented substances. The stimuli included 10 pairs of enantiomers and 6 essential oils. The bees (a) significantly distinguished between 98% of the 540 odor pairs tested, thus showing an excellent ...

Chromosomal diversity in Apis mellifera carnica from Serbia [PDF]

Apidologie, 2005
Comparative chromosomal investigations of three honey bee ecotypes of A. m. carnica (the Banat, the Timok and the Syenichko-Peshterski ecotype) from Serbia were performed. G-band analyses revealed differences between Timok and Banat honey bee ecotypes in chromosomes 2, 4, 11 and 13.

Variation in honey bee gut microbial diversity affected by ontogenetic stage, age and geographic location [PDF]

, 2015
Social honey bees, Apis mellifera, host a set of distinct microbiota, which is similar across the continents and various honey bee species. Some of these bacteria, such as lactobacilli, have been linked to immunity and defence against pathogens. Pathogen

Hydroxymethylfurfural Affects Caged Honey Bees (Apis mellifera carnica) [PDF]

Diversity, 2019
A high concentration of hydroxymethylfurfural (HMF) (e.g., 15 mg HMF per kg honey) indicates quality deterioration for a wide range of foods. In honey bee colonies, HMF in stored honey can negatively affect bee health and survival. Therefore, in the laboratory, we experimentally determined the effects of HMF on the longevity and midgut integrity of ...

Honey bee genotypes and the environment [PDF]

, 2014
Although knowledge about honey bee geographic and genetic diversity has increased tremendously in recent decades (Meixner et al., 2013), the adaptation of honey bees to their local environment has not been well studied.

Killing and replacing queen-laid eggs: low cost of worker policing in the honey bee [PDF]

, 2014
Worker honeybees, Apis mellifera, police each other’s reproduction by killing worker-laid eggs. Previous experiments demonstrated that worker policing is effective, killing most (∼98%) worker-laid eggs. However, many queen-laid eggs were also killed (∼50%
