Wachse der Honigbiene Apis mellifera carnica Pollm. [PDF]
, 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.

Molecular Ecology Resources, Volume 24, Issue 5, July 2024.Abstract Recent declines in insect abundances, especially populations of wild pollinators, pose a threat to many natural and agricultural ecosystems. Traditional species monitoring relies on morphological character identification and is inadequate for efficient and standardized surveys.

Ecology and Evolution, Volume 14, Issue 6, June 2024.The specialized hygienic behavior of selected honey bees, called varroa sensitive hygiene (VSH), was thought to cause high levels of non‐reproductive mites. To further investigate this link, we used the experimental setup and data sets from a four‐year selection project designed to breed mite non‐reproduction (MNR) and VSH colonies.

Wing morphometry of Slovak lines of Apis mellifera carnica honeybee population
Acta Fytotechnica et Zootechnica, 2016 Samples of honeybee workers and drones forewings from 16 hives belonging to various lines of Slovak Carniolan bee kept by queen breeders in Slovakia were taken in year 2013 to perform wing morphometry measurements.

Verteilung von Varroa jacobsoni im drohnenfreien Bienenvolk (Apis mellifera carnica) [PDF]
Apidologie, 1993 On a verifie la presence/absence de l'acarien Varroa jacobsoni sur environ 800 abeilles recemment ecloses et prelevees dans une colonie a l'automne. Les abeilles ont ete marquees, puis reintroduites dans la ruche. L'infestation par les acariens des abeilles marquees a ete regulierement controlee pendant 30 j (tableau I).

Sensory memory for odors is encoded in spontaneous correlated activity between olfactory glomeruli [PDF]
, 2006 Sensory memory is a short-lived persistence of a sensory stimulus in the nervous system, such as iconic memory in the visual system. However, little is known about the mechanisms underlying olfactory sensory memory.

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

Thermoregulation im Brutbereich der Honigbiene Apis mellifera carnica [PDF]
, 2005 Honigbienen (Apis mellifera carnica) regulieren die Temperatur ihrer Brut in einem sehr engen Temperaturfenster, da vor allem die gedeckelte Brut sehr temperaturempfindlich reagiert (Groh et al. 2004). Die Thermoregulation ist nicht – wie lange angenommen – Beiprodukt von alltäglichen Arbeiten der Bienen im Brutbereich, sondern eine aktive und Energie-
