Combined stress from parasites, pesticides and lack of flowers drives bee declines [PDF]
, 2015 Bees are subject to numerous pressures in the modern world. The abundance and diversity of flowers has declined, bees are chronically exposed to cocktails of agrochemicals, and they are simultaneously exposed to novel parasites accidentally spread by ...

Journal of Experimental Biology, 2008 ![Figure][1] Forager bees like nothing more than a sweet supply of nectar. But bees do not live by nectar alone. One of their main sources of protein is pollen. Knowing that bees have to maintain a reasonably high thoracic temperature for their muscles to power flight, and that foragers'

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.

Pengaruh Variasi Pollen Terhadap Karakteristik Kimia Bee pollen
Jurnal Teknologi Agro-Industri, 2021 Bee pollen contains high enough nutrition. Bee pollen contains some nutrients such as water, ash, lipid, protein, natural antioxidants, palmitic acid, oleic acid, linoleic acid, and linolenic acid. The high nutrients on bee pollen causes bee pollen to be widely used by many people as a food additive on some food productions.

Preliminary studies on different extracts of some honey bee products [PDF]
, 2013 The aim of present study was to compare the phytochemical composition of different extracts of bee pollen, propolis and honey and to analyse the best solvent for maximum phytochemicals extraction. These preliminary studies are significant in locating the

Assessing the role of dispersed floralresources for managed bees in providingsupporting ecosystem services for croppollination [PDF]
, 2018 Most pollination ecosystem services studies have focussed on wild pollinators and their dependence on natural floral resources adjacent to crop fields. However, managed pollinators depend on a mixture of floral resources that are spatially separated from

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

American Journal of Botany, EarlyView.Abstract Premise Flowers that present their anthers and stigma in close proximity can achieve precise animal‐mediated pollen transfer, but risk self‐pollination. One evolutionary solution is reciprocal herkogamy. Reciprocity of anther and style positions among different plants (i.e., a genetic dimorphism) is common in distylous plants, but very rare in

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 ...
