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...
Israeli acute paralysis virus (IAPV) is a widespread RNA of honey bees that has been linked with colony losses. Here we describe the transmission, prevalence, and genetic traits this virus, along host transcriptional responses to infections. Further, present RNAi-based strategies for limiting an important mechanism used by IAPV subvert defenses. Our study shows established as persistent infection in bee populations, likely enabled both horizontal vertical transmission pathways. The...
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....
Seven bee pollen samples (C1-C7) with different palynological sources were harvested from Pindamonhangaba municipality (Southeast Brazil). Methanol extracts of untreated (control), frozen at -18 °C and then dried analyzed by HPLC/PAD/ESI/MS/MS. Flavonoid diglycosides quercetin, kaempferol, isorhamnetin patuletin detected, together hydroxycinnamic acid amide derivatives, such as N',N'',N'''-tris-p-feruloylspermidine N',N'',N'''-tris-p-coumaroylspermidine. Distinct phenolic profiles...
Resumo: Nas últimas décadas, o declínio de populações abelhas silvestres e colapso colônias Apis mellifera têm preocupado pesquisadores apicultores. O objetivo deste artigo revisão foi compilar alguns dos estudos mais relevantes relacionados às possíveis causas desses problemas - como nutrição, manejo, patógenos, parasitas efeitos agrotóxicos -, além apresentar um breve histórico da síndrome "colony collapse disorder" (CCD) nos Estados Unidos na Europa. Abordaram-se com detalhes os...
HIGHLIGHTS Honey bee queens have the long lifespan in colony. Queen midgut undergoes epithelial cell death with age. The epithelium renewal decreases queen Midgut stem cells differentiate without proliferation.
Two species of Spiroplasma (Mollicutes) bacteria were isolated from and described as pathogens the European honey bee, Apis mellifera, ~30 years ago but recent information on them is lacking despite global concern to understand bee population declines. Here we provide a comprehensive survey for prevalence these two in current populations bees using improved molecular diagnostic techniques assay multiyear colony samples North America (U.S.A.) South (Brazil). Significant annual seasonal...
This study quantified vitamin C, E and β-carotene in samples of fresh bee-collected pollen correlating them with the botanical origin. Vitamin content varied between 13.5 42.5 µg/g for E; 56.3 198.9 273.9 560.3 C. It was concluded that origin collecting season influenced contents. There is a relationship vitamins its origin: Raphanus sp Macroptilium sp, Mimosa caesalpineafolia β-carotene; Eucalyptus Anadenanthera Arecaceae type Philodendron
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...
Bee health is a growing global concern due to phenomena with as yet undefined causes, such the sudden population decline of colonies that has been observed in apiaries many countries, recently including Brazil. The main objective this study was assess presence and/or prevalence pathogens afflict Africanized Apis mellifera bees Paraiba Valley region Sao Paulo state, Three sampling periods were established: period 1 – August and September 2009 (winter/start spring); 2 December January 2010...
Honey bees are responsible for pollinating many native and cultivated plant species. These insects can be affected by pathogens, including fungi bacteria, both of which form spores that easily dispersed within the colony means stored products, among other routes. The objective this study was to develop a method detect honey bee pathogens Nosema apis, ceranae, Ascosphaera apis Paenibacillus larvae in samples honey, pollen royal jelly. standardized each product individually, then analyzed...
Viruses and Nosema spp. presence was investigated in solitary bees, honey stingless bees from an apiary site a non-apiary Brazil. Honey bee viruses were detected social the most prevalent DWV, ABPV CBPV. Despite its abundance sites, CBPV absent site. ceranae found only IAPV, KBV, apis not detected. Simultaneous detections observed, foragers had higher diversity of viruses. Viral RNAs also ovaries, indicating possible vertical transfer these to offspring. Our findings advance our knowledge...
O conhecimento das plantas de uma região, sua época florescimento e as características do pólen, auxiliam na determinação espécies vegetais que contribuem para a composição mel. Durante o período 1994 1997 foram inventariadas, semanalmente, em diferentes horários num raio aproximadamente 300m dos apiários da USP/ESALQ, Piracicaba,SP (22°43'S, 47°27'W 580 m) Instituto Zootecnia, Pindamonhangaba, SP (22°57'S, 45°27'W 560 m), estavam sendo visitadas por abelhas. Foram anotados mês...
