Neonicotinoid insecticides are often detected in pollen and nectar, which are the main food resources for honey bees. Sub-lethal and chronic exposure to these insecticides may have a prolonged effect on honey bees who are solely dependent on the stored food inside of the hive during cold weather. Our study investigated the effects of sub-lethal concentrations of imidacloprid on late fall forager honey

Due to their foraging behavior, honey bees interact with the landscape. As a result, honey bees and their brood will be exposed to pesticides through nectar and pollen entering the hive. Although these pathways seem rather straightforward, there are several steps between the entry of nectar and pollen and its consumption by the colony. One of the aspects involved here is the time between collection

In the Cerrado, the Brazilian savanna, studies on the relationship of agroforestry systems (AFS) with the edaphic and biotic factors are still incipient. In this study, the community of bees in AFS in the Brazilian Cerrado was characterized for structural parameters and composition of these systems with respect to the richness and abundance of bees. It was determined that 56 individuals, representing

The industry demands high quality and standards-compliant beeswax, which is difficult to find in western countries. As a result, it is necessary to explore new geographical sources. This work focuses on the characterization of beeswax from Mozambique in terms of saturated hydrocarbon profile and thermal properties comparing them with others from diverse origins. The hydrocarbons found (C21H44-C35H72)

The accelerating decline of pollinator populations has become increasingly concerning in the last two decades. Honey bees are economically important pollinators and a model species to evaluate pollinator health. The decline in queen quality is one of the frequently reported causes associated with honey bee losses worldwide. Histopathology is an essential tool used for diagnostics and research in mammalian

Scientific research on honey has grown substantially over the past decades, accumulating more evidence on its role in complementary and alternative medicine. We conducted a bibliometric analysis of honey research from 2011 to 2020 to see the trend of publications in this study area.

Based on microsatellite markers and non-lethal sampling of orchid bee males, we assessed the genetic diversity and population structure of three species, Euglossa pleosticta, Euglossa imperialis, and Eulaema nigrita, collected from forest remnants in the Brazilian savanna biome. Among these species, El. nigrita has being acknowledged as more tolerant to savanic areas, since it is more frequently found

In honey production, high yields can be achieved with migratory beekeeping. Migratory beekeepers complete the honey production season by moving their colonies to areas with high nectar flow. Traditionally migratory beekeepers decide where to go based on their previous experience. Nowadays, given the rapidly changing climatic conditions, it is seen that the regions to be visited should be decided with

A study was carried out to investigate the influence of differently aged wax combs (foundation as zero, 1, 2, 3 and 4 − 6 years old) on some biological aspects that affect the productivity of honey bee colonies. Twenty-five package colonies were equally divided and situated on each of the tested combs during the spring of two successive years (2018 and 2019). The obtained results revealed that worker

Oxalic acid (OA) is a natural compound that has been used to control the honey bee (Apis mellifera) pest Varroa destructor. One method of OA application gaining popularity among beekeepers in the US involves vaporizing OA crystals with heat inside a closed hive. Herein, we tested different doses of OA applied via vaporization to determine the most effective amount of OA needed to reduce V. destructor

We present a model for tracking future task frequency distributions of individual adult worker honey bee (Apis mellifera L.) cohorts in a colony based on the composition of immatures at a specific time period. The user inputs the proportions of brood comb occupied by eggs, larvae, capped brood, or non-brood/empty cells. The model captured an experimental example where a brood comb is inserted into

Apis mellifera scutellata was introduced in Brazil in 1956. This subspecies originated from Africanized polyhybrid honey bees (A. mellifera), and quickly spread due to its high adaptability, reproductive behavior, foraging ability, and defensiveness. Good management practices have been developed that allow for good beekeeping performance of this introduced subspecies in Brazil. The selection of queens

Herein, we investigated the genetic diversity and population structure of Euglossa cordata L., an orchid bee species widely distributed at the heterogeneous set of vegetal physiognomies encompassed in a transition zone (TZ) of different Brazilian biomes. We then tested whether phytogeographic regions would play some rule for the genetic diversity. Results revealed that only 12 and 28 out 78 pairs of

Varroa and associated viruses were not

The health of western honey bees (Apis mellifera L.) is constantly affected by Nosema ceranae, a microsporidian threat to colonies worldwide. We extracted propolis, a natural product exhibiting antimicrobial properties, from honey bee hives, fed it to worker bees before or after infection with N. ceranae, and determined its ability to protect bees from and treat them after infection. Protection from

Bees of the Meliponini tribe are the most diverse group of social bees in the world and their need for trophic resources (pollen and nectar) makes them the main floral visitors and consequently the main pollinators of tropical forests. The trophic resources of stingless bees of the genera Melipona, Frieseomelitta and Plebeia (Apidae: Meliponini) were studied during the dry season of 2016 and rainy

We characterized Tetragonisca angustula and Melipona beecheii honeys produced in Costa Rica according to their physical and chemical properties. Moreover, we found critical parameters that distinguish the honeys from each other. Forty-eight samples of honey of both stingless bee species were analyzed (T. angustula, n = 32; M. beecheii, n = 16). T. angustula honey is characterized by having significantly

Propolis (bee glue) is a sticky material collected by bees from plant resins, it has been proven to possess numerous beneficial pharmacological properties: antibacterial, antiviral, antioxidant, antiinflammatory, immunostimulating, hepatoprotective, cytotoxic, etc. Nowadays, propolis is a popular remedy all over the world, and is available in either pure form or combined with other natural products

Knowledge of spatial patterns of climatically suitable habitats, and species range contractions/expansions, or shifts due to changing climate are important to improve the effectiveness of conservation efforts. Ecological niche models (ENMs) are the primary tools currently available for evaluating species’ response to anthropogenic or natural changes. We used ENMs to evaluate potential effects of future

Using melissopalynology, we aimed to identify the plant species used by Frieseomelitta longipes (Smith, 1854) in the Tapajós–Arapiuns Extractive Reserve, a protected area in the Brazilian Amazon Basin. Honey samples were collected from F. longipes colonies in the Anã and Solimões communities for one year. The honey was acetolyzed and microscopically evaluated. Overall, we identified 184 pollen types

This paper reports for the first time the presence of Aethina tumida Murray, 1867 in hives of Apis mellifera Linnaeus, 1758, established in the locality of Pucnachen Municipality of Calkini the State of Campeche, México. Nitidulids were collected manually on the honey combs in the frames of A. mellifera hives, defecating on honey and on the floor of the hives, fermenting honey making it useless. A

One of the main driving forces of the Apis mellifera colony losses reported worldwide is the nutritional stress associated with monoculture areas. We previously demonstrated under field conditions that nutritional stress that occurred during the fall impacts honey bee colony strength and health in the short and long-term. Pollen supplementation to colonies during a nutritionally stressful period increased

Sicily (Italy) is an important hotspot diversity for bees and new species records are constantly reported for the island. Here, we rediscovered after 45 years without records, the occurrence in Eastern Sicily of Lasioglossum marginatum (Brullé 1832) confirmed by DNA barcoding. This is the only known species of eusocial sweat bees (Halictidae) with perennial colonies. Since a single female was collected

Euthanasia derives from the Greek terms eu meaning good and thanatos meaning death. The term is used to describe ending the life of an individual animal in a way that minimizes or eliminates pain and distress. When animals are affected by a disease that produces insurmountable suffering or can affect other animal and human individuals or populations, or when animals are no longer fit for their purpose

American foulbrood (AFB) is one of the most devastating infectious diseases of honey bees with a worldwide distribution. Based on clinical symptoms of AFB, the disease has been thought to have long existed in the Republic of Kosovo honey bee colonies. This passive surveillance study was intended to confirm the presence and determine the distribution of AFB in the Republic of Kosovo, based on the examination

Fragmentation of the Atlantic Forest negatively impacts the population dynamics of native pollinators in these environments, especially that of stingless bees. Meanwhile, stingless bees contribute to the self-regeneration of vegetation and the sustainability of agriculture through pollination services. Thus, studies of the floral sources exploited by bees are essential for the development of conservation

This study aimed to determine the value of honey source on Robinia by analyzing flower morphology and nectar characteristics in floral nectar of eight selected individuals. The mean nectar volume secreted by genus Robinia was 1.7 ± 1.0 µL. Among the samples, PR (R. margaretta) and HR (R. pseudoacacia) secreted the highest and lowest nectar volumes—3.0 ± 1.1 and 1.1 ± 0.7 µL, respectively. The mean

Varroa destructor is arguably the most important threat to Apis mellifera honey bees. Despite the recentness of the invasion of Varroa, A. mellifera colonies naturally resistant to the mite are being observed in a growing number of populations across Europe, South Africa and Brazil. Appearing in concert with this resistance is an increase in the ability of workers to detect mite-infested cells, which

A study related to the physicochemical composition and profile of phenolic compounds and flavonoids was performed on honey of Apis mellifera L.

There is both anecdotal and empirical evidence to suggest that honey bee queen longevity has decreased in recent years, leading to premature supersedure and queen failure. This is particularly evident when beekeepers create new colonies from packages, where many queens are immediately rejected or replaced after only a few weeks. Relatively little is known about the mechanisms that trigger supersedure

Beekeeping is one of the main economic activities in several countries, and Argentina has become one of the most important exporters of honey and other products from hives. Ascosferosis, an emerging disease caused by the fungus Ascosphaera apis, affects bee larvae, causing mortality in the colonies. While many studies have focused on the infections of European Apis mellifera bees, we studied hybrid

Both Nosema ceranae and insecticides are adversely affecting honey bees. How both factors affect gene expression and honey bee survival are well studied. However, only a few studies dealt with the interactions of the two factors. Here we studied the effects of both, when alone and in combination, on honey bee survival and expression changes of immune and detoxification genes. Newly emerged bees were

Adulteration of honey represents an essential quality assurance concern in the utilisation of this natural product. Honey was serially diluted with high fructose corn syrup and analysed for its rheological profiles at 27 °C. Pure honey at ambient temperatures exhibits a peculiar non-Newtonian rheological behaviour while the behaviour of fructose syrup tends towards Newtonian. The adulteration of honey
