International Journal of Pharmaceutical Sciences and Research , 2013,
Abstract: The present study was aimed at investigating the chemical composition and antifungal activity of Ethanol Extracted Haramaya propolis (EEHP). The GC-MS analysis of EEHP showed the presence of sixteen compounds and twelve compounds were identified by means of their retention times, by comparison of their mass spectra with the NIST 2005 library data and literature. The major constituents of EEHP were Benzenamine, N,N-dibutyl- (21.94%), Paromomycin(9.74%),4-Aminobutyramide,N-methyl-N-[4-(1-pyrrolidinyl)-2-butynyl]- (9.26%) and DL-Tryptophan,5-methoxy(7.43%). The Crude EEHP showed antifungal activities against Fusarium sp., Aspergillus niger and Colletotrichum sp.. GC-MS results showed that the antifungal activities of Haramaya propolis could be because of the presence of 3-(α-Hydroxyethyl)-aniline, Benzenamine,N,N-dibutyl, DL-Tryptophan,5-methoxy, 6-Amino-5,8-dimethoxyquinazoline, Paromomycin and Imidazole,2-fluoro-5-[2-carboxyvinyl].

Journal of Tekirdag Agricultural Faculty , 2005,
Abstract: This research was conducted on the present status of beekeeping in Tekirda province. The data was obtained through the questionnaires applied to 312 beekeepers situated in centre of Tekirda , Malkara, orlu, Saray region. It is aimed to present a glance look on the status and clarify the problems of beekeepers .It was also aimed to obtain general characteristics of beekeeping in Tekirda using the results of questionnaire sampled in this region. Economic and social welfare of beekeepers and status of beekeeping in the Tekirda and solution to their problems were investigated by direct interview with beekeepers. The 13 % of total beekeepers has never taken any education , While 50 % of total beekeepers had 5 years of education, 15 % of total beekeepers had 8 years of education, 20 % of total beekeepers had 11 years of education, 2 % of total beekeepers had university education, Average number of modern and primitive type hives for the beekeepers were 40 and 5 respectively. It is stated that average honey yield per hive was 15 kg.

Abstract: Croatia has ideal ecological and climatic conditions for beekeeping. Beekeeping production is exclusively organized by family households and the production is measured by the amount of honey produced. The Croatian National Statistics Department reported that in 2005 there were 2,658 beekeepers in Croatia, 245,759 of honeybee colonies and 92.46 honeybee colonies per beekeeper. Honey production per hive was 15.9 kilos.There are three categories of beekeepers: hobby beekeepers, full-time beekeepers and part-time beekeepers. Most frequently, they use Langstroth-Root and Albert- Znidersic hives. Only one third of beekeepers migrate their hives. The marketing of honey products is not well organized and the honey consumption per citizen is low. However, honey is one of rare agricultural products, where Croatia has reached self-sufficiency. Namely, honey exported in the year 2005 was 186 thousand kilos, whereas honey import in the same year was 41 thousand kilos.Since Croatia is most likely to become an EU member in the near future, it is important to recognize the economic parameters of beekeeping production within Croatian economy. Data on economic parameters of beekeeping production in Croatia is very scarce and fragmented. Therefore, the aim of this investigation was to calculate basic economic parameters in Croatian beekeeping and to assess its economic strength. The primary assumption of this study was that the number of hives is the most important efficiency factor regarding productivity and profitability of beekeeping production. We further assumed that beekeepers with less than 50 hives cannot meet minimal conditions regarding these economic parameters.

Poljoprivreda (Osijek) , 2001,
Abstract: Beekeeping in Croatia unlike many other productions was not subsidized until mid nineties. At the time of introduction of first subsidies honey market was very inefficient, and there was hardly any market for other bee products. Several years of implementation enables first analyses. The investigation is based on two complementary data sets, quantitative data on production and subsidies and farmers attitude toward importance of various measures. Croatian beekeepers compared with their colleagues from other transitional countries make business quite well. Major characteristics of Croatian beekeeping are low density (2.7 beehives per km2), relatively high degree of concentration (22.7 beehives per beekeeper) and relatively intensive production (20 kg of honey per beehive and year). Additional importance to the beekeeping gives the export being more than 1/10 of honey production. Introduction of subsidy for honey production in 1998 resulted in 12% increased annual production in 1999. Besides, a number of beehives increased by 11% in 1999, after just one year of beekeeping subsidy. According to HSSC-a in 1997 Croatian beekeepers produced 16000 queens. In 2001 they produced already 38968. Investigation of farmers’ attitude toward influence of various subsidies on their business decisions showed that more than half of beekeepers claimed they were not influenced at all. Subsidies for honey production and queen production had, partially or fully influence on decisions of 25% beekeepers. Subsidy for queen testing had partially or fully influence on decisions of 25% beekeepers. Subsidy for beekeeping was the most important for beekeepers (30.8% of beekeepers werepartially or fully influenced), although implementation of this measure was difficult since there is no registry of the beekeepers.

Journal of Central European Agriculture , 2009,
Abstract: In this paper analysis of beekeeping conditions, number and distribution of beekeepers and honeybee colonies, annual colony losses as well as honey production, export, import and consumption are given. Beekeeping in Croatia has a long tradition. In comparison to pasture potential and necessity for pollination of cultivated and wild plants, present beekeeping is inadequately developed and distributed in different regions. According to data of the Croatian Livestock Center (2008) there are 313 978 honeybee colonies registered in the 2007 in Croatia on professional and sideline apiaries. The majority of honeybee colonies is placed in Pannonian region with 238 300 (76%), second in representation is in Mediterranean region with 59 763 (19%) and less represented is in Mountain region with 15 915 (5%) honeybee colonies. Yearly honey production is approximately 5 000 t and 2 000 t of national honey consumption (0.4 kg per capita) gives possibility for honey export. Croatia exported 1 051 in 2003, but 274 t of honey in 2007, which indicates on significant export decreasing trend. Normal 10 % of winter colony losses till 2007 increased in 2007/2008 on 55 615 (41.71 %) in Pannonian region, 13 892 (37.46 %) in Mediterranean and 5 359 (32.71 %) in Mountain region. There is a need to make beekeeping much more flexible to fit into an integrated agricultural system, as well as more oriented to the consumers’ demands, to be able to increase competitiveness.

A POPESCU,I GURESOAIE
Journal of Central European Agriculture , 2003,
Abstract: This study aimed to make an economic evaluation of a high performance modern beekeeping technology leading to an increased bee family capacity. The new technology removes the disadvantages of the traditional one utilising just natural picking based on Robinia, Lime, sunflower and wild flora, most of times deeply affected by unfavourable climate conditions (drought, rainfalls) and conducting to important bee losses during the winter season and mainly during the critical period till the next picking. The modern technology assures 75 % more bees per family, an increased queen laying capacity by 33 %,, a 50 % reduction of bee loss in winter season, by 20 % more honey , by 50 % more propolis, by 33 % more pollen, by 50 % more swarms, by 60 % more royal jelly and by 50 % more bee venom. The modern technology is based on a scientific feeding management applying a stimulating, completing and proteinic feeding (pollen cake and/or pollen substitutes such as: degreased powder milk 30 % and soya bean cake), involving peculiar costs ranking between USD 9.73-10.06 per family/year. The total bee rearing costs have been estimated at USD 17.83 in average per family/year, of which: 55.5 % feeding costs, 6.8 % queen replacement cost, 3.2 % treatments cost, 13.5 % costs for supplying new frames and combs,17.4 % transportation costs for moving of bee families and the remaining of 3.6 % labour costs. Taking into account a standard apiary (100 bee families of an increased power), a beekeeper can obtain an USD 12,100.4 annual income, by 55.9 % higher than in case of the traditional beekeeping technology. As a conclusion, the new technology assures a higher biological and economical efficiency, USD 3,350 profit gain that is a profit by 48 % higher than in case of the classic technology. For this reason, we recommend this modern technology to be implemented by beekeepers if they would like to transform their apiaries into high performance commercial farms.

Journal of Tekirdag Agricultural Faculty , 2007,
Abstract: This study was conducted to investigate present status of beekeeping and honey production levels per colony in Turkey. Data was available by questionnaire with randomly selected from 38 different city beekeeper. Survey was completed to find out the present status of beekeeping administration and education of beekeeper, Turkey one the most is suitable country for beekeeping with respect to different climate, geographic and vegetation. But honey production level per colony is lower than the expectation in Turkey. In this research, data was collected about some factors (bee race, education, administration capacity, techniques and technology, region differences and migration of beekeeping) which are assumed to having important effects on honey production and examine whether these factors were affected on production levels per colony or not.

Abstract: From Iranian propolis from the Isfahan province, five individual components were isolated: the prenylated coumarin suberosin 1, and four terpene esters: tschimgin (bornyl p-hydroxybenzoate) 2, tschimganin (bornyl vanillate) 3, ferutinin (ferutinol p-hydroxybenzoate) 4, and tefernin (ferutinol vanillate) 5. All of them were found for the first time in propolis. Compounds 2 - 5 demonstrated activity against Staphylococcus aureus.The results of the present study are consistent with the idea that propolis from unexplored regions is a promising source of biologically active compounds.Propolis (bee glue) has been used as a remedy since ancient times. At present, propolis is a popular remedy in the folk medicine of many nations and a row material for numerous over-the-counter preparations, health foods and beverages. Propolis has been proved to possess valuable biological activities: antimicrobial, antiviral, anti inflammatory, antioxidant, antitumor, etc. [1,2]. Bee glue is a plant derived product: bees collect it from resinous plant parts, and its chemical composition strongly varies in different eco-geographic zones. Despite the chemical variability however, it always demonstrates considerable biological activity, especially antimicrobial activity [3,4]. For this reason, propolis from unexplored regions attracts the attention of scientists in the search for new bioactive molecules [5]. In this article we report on the isolation of antibacterial terpene esters of phenolic acids, new propolis constituents, from bee glue originated from the central part of Iran.The total ethanol extract of Iranian propolis and the light petroleum fraction of this extract demonstrated significant antibacterial activity against Staphylococcus aureus, similar to the activity of the poplar type propolis. For this reason, GC-MS chemical profiling of this propolis was performed.The GC-MS analysis of the ethanol extract after silylation (data not shown) revealed the presence of the poplar bud met
