Concurrent Parasitism Alters Thermoregulation in Honey Bee (Hymenoptera: Apidae) Winter Clusters [PDF]

open access: yes, 2017
Thermoregulation is crucial for honey bee, Apis mellifera L. (Hymenoptera: Apidae), colony survival in temperate regions, but possible interference by parasites is currently unknown. The small hive beetle, Aethina tumida Murray (Coleoptera: Nitidulidae),

Hygienic Behaviour of Honeybee Colonies with Different Levels of Polyandry and Genotypic Composition

open access: yesJournal of Apicultural Science, 2015
Honey bee queens were inseminated with diluted, homogenised semen collected from a few dozen drones. This procedure was carried out to increase the diversity of the queens’ offspring, which is in comparison to the offspring of queens inseminated with ...

The relationship between multiple mating by queens, within-colony genetic variability and fitness in the ant Lasius niger [PDF]

open access: yes, 2003
Multiple mating has been suggested to benefit social insect queens because high genetic variation within colonies might decrease the load imposed by sterile diploid males, enhance resistance to parasites and pathogens, and lead to a more effective ...

Bioassay for grooming effectiveness towards Varroa destructor mites in Africanized and Carniolan honey bees [PDF]

open access: yesApidologie, 2001
Grooming behavior is considered a varroosis tolerance factor of Africanized honey bees, but this behavior is difficult to evaluate directly within the honey bee colony. A laboratory bioassay was developed to measure the intensity and effectiveness of grooming responses by worker bees artificially infested with one Varroa mite.

Morphological and production characteristics of carniolan honey bee (Apis mellifera carnica Poll.) from different parts of Serbia [PDF]

open access: yesBiotechnology in Animal Husbandry, 2007
Morphological and production characteristics of honey bee colonies from six regions in Serbia were examined in a two-year study. The colonies were sampled in the valleys of the Rasina and Morava rivers, on Pester and Kopaonik mountains, in Knjazevac environ and Banat region.

A comparison of the hygienic response of Africanized and European (Apis mellifera carnica) honey bees to Varroa-infested brood in tropical Brazil

open access: yesGenetics and Molecular Biology, 2000
In order to examine the significance of hygienic behavior for the tolerance to varroosis of Africanized honey bees, they were compared with non-tolerant Carniolans in tropical Brazil.

Assessing hygienic behavior and attraction to Varroa mite (Acari: Varroidae) in Iranian honey bee (Apis. mellifera meda) [PDF]

open access: yes, 2013
In the current study, the hygienic behaviors of 5th instar larva of Iranian honeybees (Apis mellifera. meda) were investigated. The results of hygienic evaluation demonstrated that 35% of Iranian honeybees are hygienic.

Potential acaricide 2-Heptatone induces brain apoptosis and negatively affects survival in honey bees: comparison with thymol

open access: yesEcotoxicology and Environmental Safety
Varroa destructor is probably one of the greatest threats to honey bees. A potential natural acaricide, 2-heptanone (2 H) has shown promise in controlling mite populations in honey bee colonies, but the effects of prolonged systemic administration of 2 H
