Honeybees Learn Odour Mixtures via a Selection of Key Odorants [PDF]

open access: yes, 2015
BACKGROUND The honeybee has to detect, process and learn numerous complex odours from her natural environment on a daily basis. Most of these odours are floral scents, which are mixtures of dozens of different odorants.

Honeybees disrupt the structure and functionality of plant-pollinator networks

open access: yesScientific Reports, 2019
The honeybee is the primary managed species worldwide for both crop pollination and honey production. Owing to beekeeping activity, its high relative abundance potentially affects the structure and functioning of pollination networks in natural ...

Learning and memory in the honeybee [PDF]

open access: yesThe Journal of Neuroscience, 1995
Insects are favorable subjects for neuroethological studies. Their nervous systems are relatively small and contain many individually identifiable cells. The CNS is highly compartmentalized with clear separations between multisensory higher order neuropiles in the brain and neuropiles serving sensory-motor routines in the ventral cord (Huber, 1974 ...

Numerical cognition in bees and other insects [PDF]

open access: yes, 2016
The ability to perceive the number of objects has been known to exist in vertebrates for a few decades, but recent behavioral investigations have demonstrated that several invertebrate species can also be placed on the continuum of numerical abilities ...

First detection of Paenibacillus larvae the causative agent of American Foulbrood in a Ugandan honeybee colony [PDF]

open access: yes, 2016
Paenibacillus larvae is a highly contagious and often lethal widely distributed pathogen of honeybees, Apis mellifera but has not been reported in eastern Africa to date. We investigated the presence of P.

The Modified Pharaoh Approach: Stingless bees mummify beetle parasites alive [PDF]

open access: yes, 2008
Social insect colonies usually live in nests, which are often invaded by parasitic species^1^. Workers from these colonies use different defence strategies to combat invaders^1^.

ColEval: Honeybee COLony Structure EVALuation for Field Surveys

open access: yesInsects, 2020
Methods for the evaluation and comparison of the structure of numerous honeybee colonies are needed for the development of applied and fundamental field research, as well as to evaluate how the structure and activity of honeybee colonies evolve over time.

Antibiotic exposure perturbs the gut microbiota and elevates mortality in honeybees

open access: yesPLoS Biology, 2017
Gut microbiomes play crucial roles in animal health, and shifts in the gut microbial community structure can have detrimental impacts on hosts. Studies with vertebrate models and human subjects suggest that antibiotic treatments greatly perturb the ...

Respiration of resting honeybees [PDF]

open access: yesJournal of Insect Physiology, 2007
The relation between the respiratory activity of resting honeybees and ambient temperature (T(a)) was investigated in the range of 5-40 degrees C. Bees were kept in a temperature controlled flow through respirometer chamber where their locomotor and endothermic activity, as well as abdominal ventilatory movements was recorded by infrared thermography ...
