A high variability was found in the moisture content (1.96–8.26%), ash (0.66–5.50%) and sensory characteristics of raw propolis from southeastern Mexico, but the raw propolis samples met the requirements of the quality regulations. In the same way, most of the ethanolic extracts also complied with the quality regulations. Of all the extracts, PE2 obtained from Santa Cruz showed the highest values for dry extract, content of total phenolic compounds (TPC), total flavonoids (TF) and antioxidant activity (DPPH and ABTS). The content of the individual phenolic compounds varied according to the geographical location of the apiary, but the PE2 extract resulted in the highest pinocembrin and chrysin content. A positive correlation was obtained between TPC and TF with antioxidant activity. Propolis extracts were classified into two groups through principal component analysis (PCA). These results indicate that the apiary location in southeastern Mexico influenced the characteristics of propolis.","PeriodicalId":14941,"journal":{"name":"Journal of Apicultural Science","volume":"65 1","pages":"109 - 122"},"PeriodicalIF":0.6,"publicationDate":"2021-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45266806","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 great importance of this study is in evaluating and validating the synergistic effect caused by the mixture of different herbal extracts. The aim of the study was to investigate through cage experiments and field studies the effect of mixed herbal essential oil extracts and to determine the most suitable application methods and doses of the product in the treatment of nosemosis. The duration of the experiments was three weeks. Results show that the herbal essential oil extract mixture (HEOEM) is effective on both Nosema apis and Nosema ceranae, and on the two together (mixed infection). With respect to application methods, the results revealed that the most suitable method is spraying HEOEM with sterilized distilled water on adult bees and on both sides of frames; 500 µL per cage and 2,000 µL per frame were found to be effective doses of HEOEM in the experimental cages and hives. HEOEM can be a viable alternative to synthetic products in the immediate future as the contents are natural and have no toxic effect on honey bees.","PeriodicalId":14941,"journal":{"name":"Journal of Apicultural Science","volume":"65 1","pages":"163 - 175"},"PeriodicalIF":0.6,"publicationDate":"2021-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49505751","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}

Unlike the well-studied V. destructor and V. jacobsoni mites, V. underwoodi remain less known. According to English language publications, the proven V. underwoodi distribution area of A. cerana colonies covers Nepal, South Korea, Indonesia, Papua New Guinea, Vietnam and China, but not Russia even though it had been described morphometrically in Russian language publications in Russia's Primorsky Territory. According to Vavilov's law (1920) of a homologous series, all the species of V. underwoodi, V. destructor and V. jacobsoni have the ability to spill over onto new hosts. Thus, V. underwoodi is a potential parasite of A. mellifera that should be carefully studied. In this study, V. underwoodi mites in colonies of honey bee subspecies A. c. ussuriensis native to Russia's Primorsky Territory are first proven using both morphometry and mitochondrial COX1 gene sequencing. The genetic divergence and p-distances between V. underwoodi and other Varroa species ranged from 7 to 10% and from 0.072 to 0.099, respectively, which matched the intraspecific level of differences. Two identical northernmost V. underwoodi samples from Russia's Primorsky Territory and China's Jilin province with GenBank accession number MH205176 were assigned as COX1 haplotype China 1 MH205176. The first discovery of V. underwoodi in the Primorsky Territory in northern Asia outlined the northern border of its range.","PeriodicalId":14941,"journal":{"name":"Journal of Apicultural Science","volume":"65 1","pages":"177 - 187"},"PeriodicalIF":0.6,"publicationDate":"2021-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42254637","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}

In northern Argentina, few studies have focused on this important entomopathogen. This is the first study on A. apis isolated from commercial pollen in Entre Ríos, Jujuy, and Misiones provinces, where its prevalence in bee colonies has not been reported. We identified this entomopathogen using macroscopic, microscopic, and molecular analyses, focusing on its botanical origin as a possible transmission route.

However, in this modern world, bees are suffering. Decreasing global domesticated and wild bee populations while the demand for agricultural pollination services is increasing is a matter of concern. Colony losses are driven by such factors or interactions as changing environmental conditions, exposure to agrochemicals, parasite and pathogens attack and decreased flower abundance and diversity. All these stresses individually or together affect the immune system of bees and consequently bee fitness. Poor nutrition is the key stressor as it directly suppresses the immune system and reduces host resistance to other stressors. To cope with these stresses, honey bees have well-developed individual and social immune systems which initiate several defence reactions, but its activation, maintenance and use are detrimental for bee survival as it occurs at the cost of bee health. This review summarizes the causal factors and their possible interaction responsible for immune suppression in honey bees.","PeriodicalId":14941,"journal":{"name":"Journal of Apicultural Science","volume":"65 1","pages":"25 - 47"},"PeriodicalIF":0.6,"publicationDate":"2021-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44245686","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}

We compared reproductive parameters and diversity of accompanying nest fauna. Population growth rate was high in all habitats, exceeding five times the number of cocoons placed in the previous year. We found no significant differences in the number of cocoons and brood mortality between areas with different urbanization levels. In nests located in suburbs, parasites and cleptoparasites occupied almost three times more nest chambers than in other habitats. Changes in the habitat structure had a significant impact on the diversity and abundance of accompanying fauna.

It is used as a sealant and antiseptic in the hive. Because of its antimicrobial properties, propolis has become a popular alternative medicine or food for health protection and disease prevention. The presence of a large number of flavonoids, aromatic acids and phenolic compounds has been suggested to be responsible for most biological and pharmacological activities of propolis. This review aims to provide a critical analysis of the different studies which evaluate the activity of propolis against fungi and to identify the chemical components responsible for such activity. The discussion of the methodological approaches used and the issued results is a key point of this review to highlight knowledge gaps. This review will first describe the chemical composition of the propolis and the factors of variability including geographical and botanical origins and then examine its antifungal activities with a focus against phytopathogenic fungi.

Because fat body cells, oenocytes and trophocytes, are known to regulated larvae metabolism, and to be affected by xenobiotics, we tested whether apoptosis of these cells can be an underlying cause of larvae death. Ten colonies were divided into two groups and fed with common honey or toxic honeydew obtained from colonies affected by “River disease”. Five-dayold larvae were collected and processed for histology and immunohistochemistry for caspase-3. The area, diameter, and immunostaining area in oenocytes and trophocytes were measured. The oenocyte and trophocyte cellular area decreased in the treated group (p=0.002; p<0.001 respectively) compared to the control group. The diameter of oenocytes (p=0.0002) and trophocytes (p<0.0001) decreased in the treated group.

Our aim was to understand better the pollination biology and role of flower insect visitors in reproduction success. Results indicated that full anthesis occured in the morning between 06.00 and 08.00 h and pollen dehiscence eight to eleven hours after anthesis. Stigma receptivity commenced nine hours after anthesis and lasted for the next 24 h. A total of eighteen insect species representing six families visited Niger flowers, and among these, Apis florea and A. cerana were dominant. The flowers were self-incompatible as there was no seed set upon the selfing of floret and selfing of capitulum. The maximum seed set (78.33±0.14%) was noticed when flowers were allowed for open pollination and the lowest was recorded when the whole plant was caged to exclude pollinator visits (0.33±0.67). The time spent by A. cerana and A. florea was 1.35±0.48 and 1.83±0.12 seconds per floret, respectively and 9.63±0.69 and 14.9±0.94 seconds per capitulum, respectively. A. cerana and A. florea were found to be more efficient pollinators of G. abyssinica. Introducing bee colonies might greatly improve the yield, and it is also important to conserve bees in the vicinity of G. abissynica fields during the flowering period. Hence, introducing bee colonies might greatly improve the yield of Niger.","PeriodicalId":14941,"journal":{"name":"Journal of Apicultural Science","volume":"65 1","pages":"85 - 99"},"PeriodicalIF":0.6,"publicationDate":"2021-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45326716","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}
