TL;DR: Estimation of the content of total phenolic substances, flavonoids, waxes, ash, volatile substances and dry residue be used as parameters to characterize samples of crude propolis and tinctures.
Abstract: SUMMARYA set of parameters and respective procedures for the establishment of chemical profiles of samples of tinctures and crude propolis is presented. It is proposed that estimations of the content of total phenolic substances, flavonoids, waxes, ash, volatile substances and dry residue be used as parameters to characterize samples of crude propolis. For tinctures, the estimations of total phenolic substances, flavonoids, waxes, specific gravity and ethanol are proposed. Total phenolic substances and flavonoids are measured by spectrophotometric methods, waxes gravimetrically and ethanol by gas chromatography. The accuracy of the spectrophotometric procedures was tested by assaying a mixture with a known composition of phenolic acids and flavonoids. The use of the procedures is exemplified by the analyses of six samples of crude propolis from different localities in Brazil and of tinctures prepared with absolute and 70% aqueous ethanol. The contents of total phenolic substances, flavonoids, waxes and vo...

TL;DR: Examination of the historical record shows that such extensive colony losses are not unusual, and it is crucial to make beekeeping a more attractive hobby and a less laborious profession, in order to encourage local apiculture and pollination.
Abstract: Apis mellifera, colony losses. honey bee, Varroa destructor Journal of Apicultural Research 49(1): 1-6 (2010) © IBRA 2010 DOI 10.3896/IBRA.1.49.1.01 Apiculture has been in decline in both Europe and the USA over recent decades, as is shown by the decreasing numbers of managed honey bee (Apis mellifera L.) colonies (Ellis et al., 2010; Potts et al., 2010). It therefore is crucial to make beekeeping a more attractive hobby and a less laborious profession, in order to encourage local apiculture and pollination. Apart from socio-economic factors, which can only be addressed by politicians, sudden losses of honey bee colonies have occurred, and have received considerable public attention. Indeed, in the last few years, the world’s press has been full of eye catching but often uninformative headlines proclaiming the dramatic demise of the honey bee, a world pollinator crisis and the spectre of mass human starvation. “Colony Collapse Disorder” (CCD) in the USA has attracted great attention, and scientists there and in Europe are working hard to provide explanations for these extensive colony losses. Colony losses have also occurred elsewhere (Figs 1 and 2), but examination of the historical record shows that such extensive losses are not unusual (vanEngelsdorp and Meixner, 2009). Almost exactly a century ago, in 1906, beekeepers on the Isle of Wight, a small island off the south coast of England, noticed that many of their honey bee colonies were dying, with numerous bees crawling from the hive, unable to fly. Despite some sceptical beekeepers suggesting that this was “paralysis”, a condition which had long been known, the colony losses were widely reported in the media, and beekeepers became convinced that the cause was a novel

TL;DR: The data support the view that honey bees are in decline at least in some regions, which is probably closely linked to the decreasing number of beekeepers.
Abstract: Growing evidence indicates that European managed honey bees are in decline, but information for Europe remains patchy and localized. Here we compile data from 18 European countries to assess trends in the number of honey bee colonies and beekeepers between 1965 and 2005. We found consistent declines in colony numbers in central European countries and some increases in Mediterranean countries. Beekeeper numbers have declined in all of the European countries examined. Our data support the view that honey bees are in decline at least in some regions, which is probably closely linked to the decreasing number of beekeepers. Our data on colony numbers and beekeepers must, however, be interpreted with caution due to different approaches and socioeconomic factors in the various countries, thereby limiting their comparability. We therefore make specific recommendations for standardized methodologies to be adopted at the national and global level to assist in the future monitoring of honey bees.

TL;DR: This paper provides easy to use protocols for the collection, identification, diagnosis, rearing, breeding, marking and measurement of infestation rates and fertility of V. destructor and describes pros and cons for all methods for the user to know which method to use under which circumstances.
Abstract: SummaryVery rapidly after Varroa destructor invaded apiaries of Apis mellifera, the devastating effect of this mite prompted an active research effort to understand and control this parasite. Over a few decades, varroa has spread to most countries exploiting A. mellifera. As a consequence, a large number of teams have worked with this organism, developing a diversity of research methods. Often different approaches have been followed to achieve the same goal. The diversity of methods made the results difficult to compare, thus hindering our understanding of this parasite. In this paper, we provide easy to use protocols for the collection, identification, diagnosis, rearing, breeding, marking and measurement of infestation rates and fertility of V. destructor. We also describe experimental protocols to study orientation and feeding of the mite, to infest colonies or cells and measure the mite's susceptibility to acaricides. Where relevant, we describe which mite should be used for bioassays since their beha...

TL;DR: These methods, described in this paper, are especially valuable when investigating the effects of pesticide applications, environmental pollution and diseases on colony survival.
Abstract: SummaryA variety of methods are used in honey bee research and differ depending on the level at which the research is conducted. On an individual level, the handling of individual honey bees, including the queen, larvae and pupae are required. There are different methods for the immobilising, killing and storing as well as determining individual weight of bees. The precise timing of developmental stages is also an important aspect of sampling individuals for experiments. In order to investigate and manipulate functional processes in honey bees, e.g. memory formation and retrieval and gene expression, microinjection is often used. A method that is used by both researchers and beekeepers is the marking of queens that serves not only to help to locate her during her life, but also enables the dating of queens. Creating multiple queen colonies allows the beekeeper to maintain spare queens, increase brood production or ask questions related to reproduction. On colony level, very useful techniques are the measu...
