Technology of storage of bee pollen and its effects on the development of honey bees

Науковий вісник Львівського національного університету ветеринарної медицини та біотехнологій імені С.З. Гжицького. Серія: Сільськогосподарські науки, 2023
The article presents data on changes in the protein content of bee pollen due to different storage methods. In May, during the collection of bee pollen by bee colonies, in the conditions of the farm located in the Stryi district of the Lviv region, more ...

Pigments in the Blue Pollen and Bee Pollen of Fuchsia excorticata [PDF]

Zeitschrift für Naturforschung C, 2000
Abstract A comparison of the pigments in Fuchsia extorticata pollen with the pigments extracted from the unusually coloured blue-black “fuchsia” bee pollen confirms the New Zealand tree fuchsia as the source of the bee pollen. The pigments were identified as the p-trans-coumaroylated derivatives of delphindin-, petunidin and malvidin-3 ...

Diversity of Plant Pollen Sources, Microbial communities and Phenolic compounds present in Bee pollen and Bee bread

Environmental Science and Pollution Research, 2023
Abstract The pollination of several crops, as well as wild plants, depends on honeybees. To get the nutrients required for growth and survival, honeybee colonies are dependent on pollen supply. Bee pollen (BP) is partially packed in honeycomb cells, and processed into beebread (BB) by microbial metabolism.

Pollen elicits proboscis extension but does not reinforce PER learning in honeybees [PDF]

, 2013
The function of pollen as a reward for foraging bees is little understood, though there is evidence to suggest that it can reinforce associations with visual and olfactory floral cues.

Pesticide Contamination in Native North American Crops, Part II—Comparison of Flower, Honey Bee Workers, and Native Bee Residues in Lowbush Blueberry

Insects
In lowbush blueberry fields, we conducted residue analysis comparing flowers, trapped pollen (honey bee and Osmia spp.), and collected bees (honey bee workers, bumble bee queens, and non-Bombus spp. wild native bees). The study was conducted from 2012 to

Does the abiotic environment influence the distribution of flower and fruit colors?

American Journal of Botany, EarlyView.
Abstract Premise Color in flowers and fruits carries multiple functions, from attracting animal partners (pollinators, dispersers) to mitigating environmental stress (cold, drought, UV‐B). With research historically focusing on biotic interactions as selective agents, however, it remains unclear whether abiotic stressors impact flower and fruit colors ...

The Resistance of Pollen Grains and their Degradation by Bees

Bee World, 1972
Although insects eat almost any kind of organic matter, pollen seems an unlikely food because it is such an extraordinarily resistant material. Intact unfossilized pollen walls can even be obtained from Mesozoic rocks by dissolving away the rock with strong chemicals. Nevertheless, pollen is utilized by many insects and is essential food for honeybees,

Reliability of the entomovector technology using Prestop-Mix and Bombus terrestris L. as a fungal disease biocontrol method in open field [PDF]

, 2016
Botrytis cinerea Pers.: Fr. is a major plant pathogen, and a new approach is needed for its control in strawberry to minimise the increasing use of synthetic fungicides.

Selection maintains floral color polymorphism in scarlet paintbrush, Castilleja coccinea, reflecting combined ecological factors

American Journal of Botany, EarlyView.
Abstract Premise Evolutionary theory predicts polymorphism should be rare; however, intraspecific variation in floral color is common and can be attributed to genetic drift, plasticity, or variable selection. Examining floral color polymorphism both within contact zones and across a species' range can reveal the mechanisms maintaining this variation ...
