Occurrence of deformed wing virus variants in the stingless Melipona subnitida and honey Apis mellifera bee populations in North Eastern Brazil [PDF]

open access: yes, 2019
Deformed wing virus (DWV) is now a global insect pathogen. Brazilian stingless bees are a diverse group often managed in close proximity to honey bees. We investigated the prevalence and load of DWV in 33 stingless bees (Melipona subnitida) and 12 honey

Floral Origin Determines the In Vitro Antibacterial Activity of Bee Pollen Collected From Western Oromia, Ethiopia

open access: yesFuture Postharvest and Food, EarlyView.
ABSTRACT Bee pollen has been used as a medicine and food supplement. The biological activity and nutrient composition of bee pollen depend on its floral origin. Therefore, it was aimed to determine the phenolic and flavonoid content and antibacterial activities of methanolic (99.9%) extract of bee pollens among flora. Floral origin was identified using

The dose makes the poison: have “field realistic” rates of exposure of bees to neonicotinoid insecticides been overestimated in laboratory studies? [PDF]

open access: yes, 2014
Recent laboratory based studies have demonstrated adverse sub-lethal effects of neonicotinoid insecticides on honey bees and bumble bees, and these studies have been influential in leading to a European Union moratorium on the use of three neonicotinoids,

The limitations of the methods of identifying the floral source of honeys [PDF]

open access: yes, 1998
The pollen grains in honey reveal the types of plants that were around when the bees produced the honey, thus it is valid to use melissopalynology to determine the geographical origin of honeys, but there are several reasons why it is less valid for ...
