1. Viruses that affect Apis mellifera and their occurrence in Brazil
RESUMO: As abelhas são insetos de grande importância na agricultura, cumprindo um papel muito importante na polinização e na renovação do ecossistema. No entanto, em diversos países têm sido relatadas perdas significativas de colônias e declínio da população de abelhas melíferas e nativas, nos últimos anos. Com isso, surgiram novos estudos sob

2. Chemical composition of propolis extract and its effects on epirubicin-induced hepatotoxicity in rats
ABSTRACT Propolis is a natural substance, produced by honeybees from the resin of various plants. The purpose of this study was to determine the chemical composition and evaluate the hepatoprotective effect of ethyl acetate extract of propolis from Tigzirt, against the toxicity induced by epirubicin which is a anticancer agent, and belongs to the family of a

3. Partial characterization of ethanolic extract of Melipona beecheii propolis and in vitro evaluation of its antifungal activity
ABSTRACT The ethanolic extract of Melipona beecheii Bennett 1831, propolis from Yucatán Mexico was evaluated in vitro for the determination of its phenolic compound content, antioxidant capacity and antifungal activity. The results were compared against those of the ethanolic extract of Apis mellifera propolis. The total phenolic content, flavonoid content

4. Headspace analysis and characterisation of South African propolis volatile compounds using GCxGC–ToF–MS
ABSTRACT Propolis also known as "bee glue or bee resin" is a resinous mixture of bee saliva or bee wax and exudate from tree trunks and flowers, produced by honeybees. The composition of propolis varies depending on the vegetation the bees can access. It is therefore expected that propolis obtained from various localities may have different chemical profiles

5. Royal jelly production with queens produced by single and double grafting in Africanized honeybee colonies
ABSTRACT. The objective of this research was to evaluate royal jelly production from Africanized honeybee queens of different lineages (lineage selected for honey production, lineage selected for royal jelly production and unselected) produced by single and double grafting and to compare royal jelly production among their offspring. Data were tested by doubl

6. Royal jelly production in Africanized colonies with selected queens, use of Chinese model cups and supplementation
ABSTRACT. This research was carried out to evaluate the royal jelly production in two trials. In Trial I, three genotypes of Africanized honeybees (Apis mellifera L.) were submitted to royal jelly production with two types of cups of different size and volume (conventional and Chinese model) and two types of supplements (commercial and formulated). A total o

7. Phenoloxidase activity and haemolymph cytology in honeybees challenged with a virus suspension (deformed wings virus DWV) or phosphate buffered suspension (PBS)
RESUMO: O sistema imune inato das abelhas consiste principalmente em peptídeos antimicrobianos, imunidade celular e melanização. Para investigar a resposta imune das abelhas a estressores imunológicos, foram testados três graus de estresse. Abelhas recém-emergidas naturalmente infectadas por DWV foram coletadas de um apiário livre de Varroa e dividid

8. Expression and Localization of Olfactory Receptor AcerOr1 from Chinese Honey Bee, Apis cerana cerana (Hymenoptera, Apidae)
ABSTRACT Olfactory receptors are essential for recognition and detection of odor in honeybees. Although we have cloned and characterized the sequence of olfactory receptor AcerOr1 before, the tissue distribution and location of this gene in the nurse and the forager worker Apis cerana cerana were not very clear. To further investigate this information of Ace

9. Updating Finite Element Model Using Stochastic Subspace Identification Method and Bees Optimization Algorithm
Abstract This study investigates the application of operational modal analysis along with bees optimization algorithm for updating the finite element model of structures. Bees algorithm applies instinctive behavior of honeybees as they look for nectar of flowers. The parameters that needed to be updated are uncertain parameters such as geometry and material

10. A clinical trial protocol to treat massive Africanized honeybee (Apis mellifera) attack with a new apilic antivenom
Abstract Background Envenomation caused by multiple stings from Africanized honeybees Apis mellifera constitutes a public health problem in the Americas. In 2015, the Brazilian Ministry of Health reported 13,597 accidents (incidence of seven cases per 100,000 inhabitants) with 39 deaths (lethality of 0.25%). The toxins present in the venom, which include m

11. A research on the chemical and microbiological qualities of honeys sold in Istanbul
Abstract Honey, produced by honeybees from nectar in flowers and plants, is an aqueous supersaturated sugar solution, mainly composed of fructose and glucose. The quality and biochemical properties of honey are related to honey maturity, production methods, processing and storage conditions, climatic conditions as well as the nectar source of the honey.

12. Massive attack by honeybees in a German shepherd dog: description of a fatal case and review of the literature
In the present study, a fatal case caused by honeybee (Apis cerana) stings was documented in a female German shepherd dog that was presented at the Veterinary Teaching Hospital, University of Agriculture Faisalabad, Pakistan. Characteristic clinical signs included hematuria, hematemesis, incoordination and convulsions along with evidence of massive honeybee
