Towards a Stable Host–Parasite Relationship Between Honey Bees and Varroa Mites Through Innovative Beekeeping

Environmental Microbiology, Volume 27, Issue 5, May 2025.
An innovative Varroa treatment increases Varroa pressure and Deformed Wing Virus (DWV‐B) load in summer. The increased mite and virus levels are reduced with effective summer treatment so that finally there is no difference between both groups in terms of DWV‐B and mite load shortly before overwintering.

Performance of two honey bee subspecies during harsh weather and Acacia gerrardii nectar-rich flow

Scientia Agricola
Both climatic factors and bee forage characteristics affect the population size and productivity of honey bee colonies. To our knowledge, no scientific investigation has as yet considered the potential effect of nectar-rich bee forage exposed to drastic ...

Pollen elicits proboscis extension but does not reinforce PER learning in honeybees [PDF]

, 2013
The function of pollen as a reward for foraging bees is little understood, though there is evidence to suggest that it can reinforce associations with visual and olfactory floral cues.

Integrative Genomics Reveals the Genetics and Evolution of the Honey Bee’s Social Immune System [PDF]

, 2019
Social organisms combat pathogens through individual innate immune responses or through social immunity—behaviors among individuals that limit pathogen transmission within groups.

Population-wide modelling reveals prospects of marker-assisted selection for parasitic mite resistance in honey bees

Scientific Reports
In 2019, a joint eight-variant model was published in which eight single nucleotide polymorphisms (SNPs) in seven Apis mellifera genes were associated with Varroa destructor drone brood resistance (DBR, i.e. mite non-reproduction in drone brood). As this

Protein levels and colony development of Africanized and European honey bees fed natural and artificial diets [PDF]

, 2013
Pollen substitute diets are a valuable resource for maintaining strong and health honey bee colonies. Specific diets may be useful in one region or country and inadequate or economically unviable in others.

Heritability of hygienic behavior in grey honey bees (Apis mellifera carnica) [PDF]

Acta veterinaria, 2008
Breeding grey A. m. carnica queens for hygienic behavior is beneficial for commercial beekeeping in Serbia, since hygienic behavior is associated with the resistance to the mite Varroa destructor, as well as to American foulbrood and chalk brood. In this work, heritability of hygienic behavior was analyzed in autochthonous grey A. m. carnica honey bees

Correlation of Total Polyphenol and Flavonoid Content With Antioxidant Activity of Caucasian Bee Honey

Food Science &Nutrition, Volume 13, Issue 1, January 2025.
This study includes the correlation between the phenolic contents and antioxidant activities of 54 Caucasian bee honey samples obtained from the Artvin and Ardahan regions, the most important gene centers of the Caucasian bee in Türkiye. The difference in the phenolic content and antioxidant activities of Caucasian bee honey is due to its geographical ...
