Nutritive value and apparent digestibility of bee-collected and bee- stored pollen in the stingless bee, Scaptotrigona postica Latr. (Hymenoptera, Apidae, Meliponini)
(Elsevier B.V., 2000-01-01)
In Meliponini bees, pollen is stored inside the hive. We compared the nutritional value and apparent digestibility of bee-collected and bee-stored pollen of Scaptotrigona postica. The results showed no differences in ...
Weakness and collapse of bee colonies in Brazil: are there cases of CCD?
(Empresa Brasil Pesq Agropec, 2016-05-01)
In the last decades, the decline of wild bee populations and the collapse of Apis mellifera colonies have concerned researchers and beekeepers. The objective of this review was to compile some of the most relevant studies ...
Harvesting season and botanical origin interferes in production and nutritional composition of bee pollen
(2018-01-01)
We aimed to evaluate the frequency of bee pollen production, its botanical origin and chemical composition when collected in different seasons. Our results indicate that higher proteins (22.80 ± 3.09%) and flavonoids ...
Seasonal variation of flavonoid content in bee bread: Potential impact on hypopharyngeal gland development in Apis mellifera honey bees
(2020-03-14)
Bee bread is the main source of proteins necessary for the development of hypopharyngeal glands in nurse bees. However, the seasonal chemical composition and its effects on honey bee physiology are poorly understood. Thus, ...
Africanized honey bees more efficiently convert protein diets into hemolymph protein than do Carniolan bees (Apis mellifera carnica)
(FUNPEC-EDITORA, 2009)
The superiority of Africanized over European honey bees in tropical and subtropical regions of the New World is both well documented and poorly understood. As part of an effort to try to understand the process by which the ...
Conversion of High and Low Pollen Protein Diets Into Protein in Worker Honey Bees (Hymenoptera: Apidae)
(Entomological Society of America, 2013-08-01)
Adequate protein levels are necessary to maintain strong honey bee [Apis mellifera (L.)] colonies. The aim of this study was to quantify how pollens with different crude protein contents inßuence protein stores within ...
Effect of Protein Supplementation in the Bee Apis mellifera L. Exposed to the Agrochemical Fipronil
(2021-09-01)
Inadequate quantity and quality of proteins in honey bee diet can cause weakening of their colonies and damage their resistance to agrochemical contamination, such as fipronil, which is highly toxic to bees. Thus, we tested ...
Worker bees (Apis mellifera) deprived of pollen in the first week of adulthood exhibit signs of premature aging
(Elsevier B.V., 2022-07-01)
Pollinator populations, including bees, are in rapid decline in many parts of the world, raising concerns over the future of ecosystems and food production. Among the factors involved in these declines, poor nutrition ...
