Contribution Concerning the Behaviour Knowledge before Natural Swarming in Honeybees (Apis mellifera carpathica, Linnaeus)

Bulletin of University of Agricultural Sciences and Veterinary Medicine Cluj-Napoca. Animal Science and Biotechnologies, 2020
In this study we followed the way in which evolves the behaviour of some honeybee families (Apis mellifera carpathica, Linnaeus), maintained in vertical beehives (modified Dadant type), in conditions of stationary bee keeping, having in view the natural ...

Brood thermoregulation effectiveness is positively linked to the amount of brood but not to the number of bees in honeybee colonies

Peer Community Journal, 2023
To ensure the optimal development of brood, a honeybee colony needs to regulate its temperature within a certain range of values (thermoregulation), regardless of environmental changes in biotic and abiotic factors.

Honeybee Colony Vibrational Measurements to Highlight the Brood Cycle [PDF]

, 2015
Insect pollination is of great importance to crop production worldwide and honey bees are amongst its chief facilitators. Because of the decline of managed colonies, the use of sensor technology is growing in popularity and it is of interest to develop ...

Behavioral modifications lead to disparate demographic consequences in two sympatric species

Ecology and Evolution, 2019
Life‐history theory suggests species that typically have a large number of offspring and high adult mortality may make decisions that benefit offspring survival in exchange for increased adult risks.

Low-Temperature Stress during Capped Brood Stage Increases Pupal Mortality, Misorientation and Adult Mortality in Honey Bees

PLoS ONE, 2016
Honey bees (Apis mellifera) are key pollinators, playing a vital role in ecosystem maintenance and stability of crop yields. Recently, reduced honey bee survival has attracted intensive attention.
