Propolis is a hive product containing chiefly beeswax and plant-derived substances such as resin volatile compounds. has been used an antiseptic wound healer since ancient times interest for the increased recently. Probably few plant species contribute major sources. Green propolis derives mainly from vegetative apices of Baccharis dracunculifolia (alecrim plants). However, wide variation detected in chemical composition suggests contributions alternative Predominant components green are...
Propolis, a honeybee product, has gained popularity as food and alternative medicine. Its constituents have been shown to exert pharmacological effects, such anti-microbial, anti-inflammatory anticancer. Shoot apices of Baccharis dracunculifolia (alecrim plant, Asteraceae) pointed out sources resin for green propolis. The present work aimed (i) observe the collecting behavior bees, (ii) test efficacy histological analysis in studies propolis botanical origin (iii) compare chemistries alecrim...
Total phenolic contents, antioxidant activity and chemical composition of propolis samples from three localities Minas Gerais state (southeast Brazil) were determined. contents determined by the Folin-Ciocalteau method, was evaluated DPPH, using BHT as reference, analyzed GC/MS. Propolis Itapecerica Paula Cândido municipalities found to have high pronounced activity. From these extracts, 40 substances identified, among them simple phenylpropanoids, prenylated sesqui- diterpenoids....
Propolis is a bee product with wide diversity of biological activity. It has complex composition, which dependent on its botanical source. The present study aimed to determine the chemical profile, antioxidant activity and origin two samples propolis type from locations state Rio Grande do Norte (RN, north-east Brazil).The standard characteristics RN are similar or superior internationally marketed Brazilian green propolis. have high activity, corresponding 10% (municipality Afonso Bezerra)...
Apis mellifera L. is the main pollinator of cultivated plants. With increased emphasis on organic agriculture, use botanical insecticides has also increased. However, effects these products bees remain to be determined. In this study, we aimed at assessing acute toxicity and sublethal behavioral such as andiroba oil, citronella eucalyptus garlic extract, neem rotenone honey bees, A. . Only oil demonstrated no lethality adult workers. an bee larvae. Except for larvae fed with syrup containing...
Abstract The composition of propolis, a resinous hive product collected by honeybees from various plant sources, depends on factors such as season and vegetation the area. Based standards (either isolated Brazilian propolis or reported propolis) including chromane, diterpenes phenolic compounds, different were analysed LC‐MS in order to determine their chemical constituents. Dicaffeoylquinic acids detected almost all water extracts whereas diterpenes, flavonoids prenylated compounds found...
Geopropolis is a product containing wax, plant resin, and soil particles. It elaborated by stingless bees of tribe Meliponini. Methanol extracts sample geopropolis produced Scaptotrigona aff. depillis [corrected] ("mandaguari") in the state Rio Grande do Norte (RN, northeast Brazil) were analyzed for determination standard parameters (total phenols, total flavonoids, radical scavenging activity) chemical characterization HPLC-DAD-MS/MS analysis. The has high contents phenols as well...
O objetivo deste trabalho foi avaliar a influência das composições florísticas locais sobre qualidade do pólen apícola, em dois apiários de Minas Gerais. Em cada apiário, foram instaladas cinco colméias Apis mellifera (L.). A flora polinífera identificada nas proximidades dos apiários. As bolotas coletadas agosto dezembro 2005. análise melissopalinológica realizada pelo método padrão europeu. Foram realizadas análises nutricionais relativas à porcentagem matéria seca, orgânica e mineral,...
Sacbrood disease, an affliction of honey bees (Apis mellifera) characterized by brood that fails to pupate and subsequently dies, is important threat bee health.The disease caused the sacbrood virus (SBV), a positive-, single-stranded RNA in order Picornavirales.Because economic importance for both pollination production, it vital understand monitor spread viruses such as SBV.This has been found many places across globe, including recently some South American countries, likely will continue...
Pollen load samples from 10 hives of Apis mellifera (L.) were analyzed based on their physicochemical composition and botanical source, considering color as a parameter for quality control. In seven it was possible to establish the occurrence more than 80% single pollen type, characterizing them unifloral but with protein content variation. One exclusively composed saprophytic fungi (Cladosporium sp.). Comparing mean results loads those nutritional components load, former presented higher...
Procurou-se conhecer a flora de importância polinífera para Apis mellifera (L.) na região Viçosa, MG, em período entressafra mel, entre agosto e dezembro 2005. O experimento foi realizado dois apiários distintos, cada um com cinco colmeias. As cargas retidas nos coletores pólen instalados nas colmeias foram analisadas quanto à origem botânica. plantas floração no entorno dos coletadas identificadas. A maioria das abelhas Viçosa era nativa, localizada jardins hábito arbóreo. Pela análise...
Due to their ecological and economic importance, honey bees have attracted much scientific attention, which has intensified due the recent population decline of these insects in several parts world. Among factors related patterns, infection by pathogens are most relevant, mainly because easy dissemination microorganisms. Although no zoonotic diseases associated with insects, presence infectious agents bee products should still be considered they play a role as disease dispersers, increasing...
A sensibilidade, in vitro, de amostras Staphylococcus aureus, sp.coagulase negativos, Streptococcus agalactiae e bactérias do grupo dos coliformes, isoladas leite vacas com mastite, a diferentes extratos própolis, na concentração 100 mg/ ml, foi avaliada pela técnica antibiograma em discos papel filtro sobrecamada meio cultura.Os resultados mostraram que o extrato etanólico própolis comercial, os e, menor proporção, metanólico inibiram crescimento das Gram-positivas, negativos agalactiae.Os...
In Brazil, the ectoparasitic mite of bees Varroa destructor Anderson and Trueman (Acari: Varroidae) remains at low levels infestation causing no major damage. However, with introduction possible dominance a new haplotype (K) mite, usually found in areas high rates (IR), it is necessary to monitor select beehives that are resistant pest order avoid future problems. Several factors listed as potentially being responsible for dynamics infestation, among which hygienic behavior (HB) stands out....
We developed a method for rearing larvae of Africanized bees under laboratory conditions to determine the amount diet needed during larval development obtain worker bee.We started with 18-24 h old, which were transferred polyethylene cell cups and fed five days.We found that successful was: 4, 15, 25, 50, 70 µL first fifth days, respectively.The survival rate adult stage was 88.6% when received daily divided into two feedings, 80% they only one feeding per day.The weight obtained in...
