Thus, the artificial neural network (ANN) and regression models were used for the rheological characterization of Brazilian honeys, based on low-cost measurements of water content and temperature. The steady shear viscosity (η) performed well when measured in the test phase in a 2-12-1 neuron multilayer perceptron (MLP) ANN (model 1) with a root mean square error (RMSE) and correlation coefficient (r) equal to 0.0430 and 0.9681, respectively. The parameter loss modulus (G″), storage modulus (G′) and complex viscosity (η*) were predicted in the temperature sweep test by small amplitude oscillatory shear (SAOS) measurements during heating and cooling, and the MLP ANNs with architectures of 2-9-3 (model 2) and 2-3-3 (model 3) showed RMSE values equal to 0.0261 and 0.0387 in the test phase, respectively. For all the determined parameters, non-linear exponential models showed similar results to models 1, 2 and 3. An ANN with 3-9-3 architecture (model 4) showed RMSE and r for G′ equal to 0.0158 and 0.7301, for G″ equal to 0.0176 and 0.9581, and for η* equal to 0.0407 and 0.9647, respectively, in the test phase for date of the frequency sweep test obtained by SAOS. These results were far superior to those obtained by second-order multiple linear models. The acquisition of all models is an important application for the processing of honey and honey-based products, since these properties are essential in engineering calculations and quality control of products.","PeriodicalId":14941,"journal":{"name":"Journal of Apicultural Science","volume":"64 1","pages":"219 - 228"},"PeriodicalIF":0.6,"publicationDate":"2020-11-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42291973","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Not only amount, type and consumption rate of feeds are important but the conversion and its nutrient availability are essential. In the current study, we investigated how honey bee colony's brood rearing enhanced by feeding natural pollen powder (packed on cells of drawn-out combs) in comparison with patty forms natural-pollen, Mega-bee and Ultra-bee pollen substitutes during dearth period. The study showed that colonies given the pollen powder (packed on cells of drawn out combs) immediately converted it into beebread similar to naturally collected pollen. The colonies in the packed pollen-powder group showed consistent increment and on average reared 86.3% more brood than the patty-form natural pollen, Mega-bee and Ultra-bee pollen substitutes, without having significant differences in their consumption rate. The colonies in the packed-pollen group performed better might be because the conversion of the packed-pollen powder into beebread allows better nutrient availability due to its fermentation by nest microbes and further biosynthesis process. Moreover, the presence of beebread from packed-pollen adjacent to the brood combs represents the natural way of feed reserve storage which might also contribute to the stimulation of brood rearing in colonies better than feeding in patty-forms of natural pollen, Mega-bee and Ultra-bee. Packed-pollen feeding as an alternative to patty forms could improve dearth period maintenance and early population building of colonies.","PeriodicalId":14941,"journal":{"name":"Journal of Apicultural Science","volume":"64 1","pages":"189 - 198"},"PeriodicalIF":0.6,"publicationDate":"2020-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44985891","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The objective of this study was to verify the microbiological quality of honey produced by beekeepers associated with Cooperative. Sixty-seven honey samples were evaluated for microbiological quality, and the mean values observed to total aerobic mesophiles were 2.52 log CFU/g; Clostridium spp. 1.46 log CFU/g; total coliforms 0.78 log CFU/g; fecal coliforms 0.50 log CFU/g; total yeasts 0.46 log CFU/g, and 2.95 log CFU/g total molds. The evaluations showed the incidence of anaerobic mesophilic in 70% of the samples, Clostridium spp. 77%; total coliforms 60%, fecal coliforms 62%, molds 83% and 34% yeasts. Five genera of the isolated molds commonly found in honey were Fusarium spp. 0.35 log CFU/g; Aspergillus spp. 0.52 log CFU/g; Cladosporium spp. 1.2 log CFU/g, Phoma spp. 0.71 log CFU/g and 0.16 log CFU/g Penicillium spp. Multivariate analysis showed the formation of two groups and indicated the heterogeneity in the bacterial load of the samples. Although microbiological analyses were not mandatory for honey, these results demonstrated the hygienic-sanitary quality of the samples of honey produced. For the reduction of secondary-origin microorganisms, the handlers were recommended to follow the sanitary hygiene norms and handling techniques.","PeriodicalId":14941,"journal":{"name":"Journal of Apicultural Science","volume":"64 1","pages":"209 - 218"},"PeriodicalIF":0.6,"publicationDate":"2020-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47741294","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Results indicated that 80% Algerian samples fulfilled international standards, whereas only 21.4% imported honeys were in agreement with the current regulations. 13.3% Algerian samples and 7.1% imported honeys showed values of proline lower than 180 mg/kg, which is the recommended limit for authentic honeys. Comparing Algerian and imported honeys, electrical conductivity, degrees Brix, diastase activities and proline contents were higher in Algerian honeys, in contrast to moisture percentages, hydroxymethylfurfural contents and acid phospatase activities that were higher in imported honeys. Methanolic extracts of Algerian samples were richer both in total phenolics and flavonoids determined in alkaline medium. There were not significant differences between Algerian and imported samples concerning pH, free acid, invertase, total carotenoid, total phenolics of raw honeys and TEAC, as well as regarding total flavonoids determined in neutral medium and o-diphenols of honeys’ methanolic extracts. Principal components analysis showed a good separation between Algerian and imported samples, only one multifloral Algerian honey being misclassified.

These subspecies are the product of natural selection in their native range. Nevertheless, anthropogenic impacts such as migratory beekeeping and use of non-native queens result in an admixture of these subspecies and their ecotypes. I aimed to develop a SNP-based method to detect whether queen honey bees were mated with drones from foreign subspecies. For this purpose, Caucasian and Italian queens and drones were reared. Each queen was instrumentally inseminated with mixed semen collected from Caucasian (4 μl) and Italian drones (4 μl). The spermathecae of queens were dissected out after the onset of oviposition. The DNA was extracted from each spermatheca and from the thoraces of Caucasian and Italian drones. Seven regions on mtDNA that were isolated from drones were sequenced to determine the SNPs, enabling the discrimination of Caucasian sperm from Italian in spermathecal contents. Based on one SNP (11606. bp, T/C) residing on the Cytb gene, a specific primer was designed to be used in High Resolution Melting (HRM) analysis. HRM analysis indicated that heteroduplex peak profiles were present in all spermathecal contents of instrumentally inseminated queens. The results provide proof of the concept that the presence of likely non-native mitochondrial lineages can be detected by HRM analysis based on the SNP genotyping of spermathecal contents.","PeriodicalId":14941,"journal":{"name":"Journal of Apicultural Science","volume":"64 1","pages":"241 - 249"},"PeriodicalIF":0.6,"publicationDate":"2020-09-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47359103","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Paenibacillus larvae, the causative agent of American foulbrood, is one of the most important bacterial pathogens that affect bee health. In some countries, the use of antibiotics is the most common method for the prevention and treatment of P. larvae infected colonies, however this application can also increase the risk of occurrence of resistant strains. An ecological alternative is the use of vegetal extracts containing bioactive compounds, such as polyphenols. The aim of this study is to check the antimicrobial activity of phenolic extracts of apple pomace, from the cider industry, against P. larvae strains by the broth micro dilution method. In addition, the toxicity of the phenolic extracts on A. mellifera was verified using the complete exposure method. All extracts contain from 715.31 to 11348.16 μg gal/g DW, determined by Folin-Ciocalteu show antimicrobial activity against P. larvae genotype ERIC I, ranging from 23 μg/mL to 150 μg/mL.

Because Muğla accounts for 90% of pine honey production in the world, the study area has vital importance for the Turkish (also for other countries) beekeeping sector and this importance reveals the necessity of both monitoring and predicting the LUCC of Muğla in future. This study demonstrates a combined CA-Markov land use change model and beekeeping suitability analysis via Multi-Criteria Decision Analysis (MCDA) to predict the future of beekeeping suitability in Muğla in the Geographical Information Systems (GIS) platform. 2006 and 2012 LUCC maps were used to predict the 2018 LUCC, and transition probabilities between land cover classes were analyzed. A recent 2018 LUCC map was used to demonstrate accuracy analysis of the predicted 2018 LUCC map. Considering the 0.96 Kappa accuracy, a good fit was determined and the CA-Markov model was used to predict the 2025, 2030, 2040 and 2050 LUCC maps. Moreover, using the Analytical Hierarchy Process (AHP), beekeeping suitability assessment was generated. The results indicate that there will be a considerable increase in the urban areas and decrease in grasslands in the future. Related to this, the suitable areas will be decreased by 50 km2 and non-suitable areas will be increased by 76 km2 from 2018 to 2050. The study simulated the beekeeping suitability to guide beekeepers and local authorities towards a better understanding of the reasons for decreasing suitability and developing urgent land use management systems.","PeriodicalId":14941,"journal":{"name":"Journal of Apicultural Science","volume":"64 1","pages":"263 - 276"},"PeriodicalIF":0.6,"publicationDate":"2020-08-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43309057","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
