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

CXIX Apis Mellifera Die gyptischen Bienenst cke sind die sonderbarsten in ihrer Art. Sie werden aus zerhacktem Stroh und Erde gemacht, welchs vermischt, und fest in einander gedruckt wird. Hieraus wird ein hohler Zylinder von einer Spanne im Durchmesser formiert, der so lang kann gemacht werden, als man will, von drey bis sechs Ellen. Wenn er in der

Diet breadth shapes gut microbiota in the invasive hornet Vespa velutina
Insect Conservation and Diversity, EarlyView.Dietary and microbial profiles of V. velutina larvae are dominated by Apidae and Firmicutes, respectively. DNA metabarcoding of larval meconium and gut samples reveals a significant positive correlation between prey richness and bacterial diversity in the invasive hornet V. velutina. Multiple significant correlations exist between dietary and microbial

Late Winter Foraging by Honeybees (Hymenoptera: Apidae) at Sapsucker Drill Holes [PDF]
, 2017 Observations of Apis mellifera foraging at sapsucker drill holes were made during February 1988 in southwestern Virginia. Foraging bouts were dependent upon temperature; more bees visited drill holes when ambient temperatures exceeded 10oC. Honeybees did

Journal of Applied Entomology, EarlyView.ABSTRACT Flies (Diptera) are important pollinators in global agriculture, yet little is known about how intraspecific trait variation influences their pollination performance. We compared morphological traits, foraging behaviour and pollination‐related performance metrics between laboratory‐reared (hereafter lab‐reared) and wild populations of ...

Biotropia: The Southeast Asian Journal of Tropical Biology, 2011 Â Pollinators are well known to provide key ecosystem. Animal pollinators are thought to contribute between 15 and 30% of global food production and bees are recognized to be the most important taxon.

Journal of Applied Entomology, EarlyView.ABSTRACT Climate change and environmental disasters can jointly impact species distributions and ecosystem stability, including pollinators and the resources they rely on. We used occurrence and climate data to predict the distribution of Apis mellifera in the Doce River Basin, south‐east Brazil, under baseline and future scenarios (2050).

The effects of methyl parathion on the colony dynamics of Apis mellifera : a thesis submitted in partial fulfilment of the requirements for the degree of Master of Science in Ecology at Massey University, Palmerston North, New Zealand [PDF]
, 2000 The detrimental effects of pesticides to honey bee colonies were assessed using a combination of electronic and manual sampling techniques. Initial experiments determined that electronic bee counters could be used to identify and monitor toxic events ...

Thiamethoxam impairs honey bee visual learning, alters decision times, and increases abnormal behaviors. [PDF]
, 2020 Learning is important for honey bee fitness and the pollination services that they provide. Neonicotinoid pesticides impair learning, fitness, colony health, and pollination, but most studies on how they affect bee learning have focused on olfactory ...
