Pyrrolizidine alkaloids in honey and bee pollen.
A total of 3917 honey samples and 119 'bee pollen' samples (pollen collected by honeybees) were analysed for pyrrolizidine alkaloids (PAs). Some 0.05 M sulphuric acid was used for extraction followed by a clean-up step by means of solid-phase extraction. Separation and detection was achieved by target analysis using an LC-MS/MS system. PAs were found in 66% of the raw honeys (bulk honey not yet...
متن کاملNo apparent correlation between honey bee forager gut microbiota and honey production
One of the best indicators of colony health for the European honey bee (Apis mellifera) is its performance in the production of honey. Recent research into the microbial communities naturally populating the bee gut raise the question as to whether there is a correlation between microbial community structure and colony productivity. In this work, we used 16S rRNA amplicon sequencing to explore t...
متن کاملInfluence of Pollen Nutrition on Honey Bee Health: Do Pollen Quality and Diversity Matter?
Honey bee colonies are highly dependent upon the availability of floral resources from which they get the nutrients (notably pollen) necessary to their development and survival. However, foraging areas are currently affected by the intensification of agriculture and landscape alteration. Bees are therefore confronted to disparities in time and space of floral resource abundance, type and divers...
متن کاملBarrier Immune Effectors Are Maintained during Transition from Nurse to Forager in the Honey Bee
Foragers facilitate horizontal pathogen transmission in honey bee colonies, yet their systemic immune function wanes during transition to this life stage. In general, the insect immune system can be categorized into mechanisms operating at both the barrier epithelial surfaces and at the systemic level. As proposed by the intergenerational transfer theory of aging, such immunosenescence may resu...
متن کاملEffects of propolis, royal jelly, honey and bee pollen on growth performance and immune system of Japanese quails
Effect of ethanolic extract of propolis, royal jelly, honey and bee pollen in comparison with virginiamycin (as growth promoter antibiotic) as regards the performance and immune system of Japanese quail were assessed. We used 256 mixed-sex quail chicks in a completely randomized design by eight treatments, including control, ethanolic extract of propolis 1000 (PE1) and 5000 (PE2) mg kg-1</...
