Varroa destructor causes severe damage, including a decrease in bee longevity and immunosuppression, and acts as a vector for viruses, such as Deformed wing virus (DWV-A). The surveillance of viral pathogens in V. destructor samples is essential to assess risks of emerging virulent viral variants (such as VDV-1) and evaluate their impact on honey bee health. Thus, the objective of this study was to identify viral pathogens in V. destructor and honey bee samples collected in Ontario, Canada, from 2015 to 2019 with the use of metagenomics and real time PCR (qPCR). DWV-A and VDV-1 had the highest abundance of viral transcripts (7.5 log2 and 5.72 log2, respectively). Acute bee paralysis virus (ABPV) and Bee macula virus were also identified. Viral identification and quantification in V. destructor samples using metagenomics will facilitate the surveillance of viral pathogens. This surveillance technique will assist diagnostic laboratories in delivering timely and accurate diagnoses and risk assessments, which in turn will help honey bee producers to take adequate measures to mitigate the damage caused by V. destructor and associated viruses.","PeriodicalId":14941,"journal":{"name":"Journal of Apicultural Science","volume":"66 1","pages":"209 - 215"},"PeriodicalIF":0.6,"publicationDate":"2022-08-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47370981","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 South Korea, in September 2016, this honey bee parasite was first identified in apiaries in Miryang, Gyeongnam Province. However, the invasion pathway of SHB has not been identified, and honey bee pathogens harbored by SHB have not been well characterized. Therefore, phylogenetic analysis of SHB with the use of COI gene and detection of fourteen common honey bee pathogens were conducted in this study. The confirmation of the fourteen honey bee pathogens in SHB showed that this beetle carries black queen cell virus and deformed wing virus. Therefore, SHB could have a role in the spread of these viruses. The way of entry of the SHB to South Korea remains undetermined, but the phylogenetic analysis of the COI gene revealed that it was most similar to species found in the USA. There is an urgent need for national-level monitoring and quarantine measures for preventing the spread of SHB infestation in South Korea.","PeriodicalId":14941,"journal":{"name":"Journal of Apicultural Science","volume":"66 1","pages":"45 - 55"},"PeriodicalIF":0.6,"publicationDate":"2022-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46430194","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}

Previous studies have compared the effect of pollen and carbohydrate-only diet on honeybee physiology. The effect of a monofloral versus polyfloral diet on the African honeybee (Apis mellifera scutellata) is poorly understood. This knowledge is critical as diversity-rich habitats are being altered to less diverse environments through increased urbanization and intensified agricultural activities, particularly in sub-Saharan Africa. Here, we report how lowly diverse (LD) and highly diverse (HD) pollen diets influence honeybee life-history traits and physiology. To achieve this, we fed caged bees with the two pollen diets and tested their effects on the parameters of survival, body weight, pollen consumption, and immune response. HD-fed bees had significantly higher survival and greater pollen consumption than LD-fed bees. However, LD-fed bees were heavier than HD-fed bees. The correlation between body weight gain and pollen consumption was expressed strongly in HD-fed bees than in LD-fed bees. Overall, our findings reveal the benefits that the highly diverse polyfloral diets provide to honeybee workers. This study shows how pollen diversity influences honeybee life-history traits, thus informing the need for conserving the biodiversity of environments for safeguarding the health of honeybees and other pollinators.","PeriodicalId":14941,"journal":{"name":"Journal of Apicultural Science","volume":"66 1","pages":"29 - 43"},"PeriodicalIF":0.6,"publicationDate":"2022-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44613857","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 study was conducted under a greenhouse environment for five months, from October to the end of February. The juvenile hormone analogue methoprene supported the termination of bee diapause. Experimental results from Osmia pollination plots were compared with control plots that applied the hand-pollination method. Plants with flowers pollinated by the solitary bee had significantly more fruits than those pollinated by the hand method in November, December and February. In addition, significantly more seeds per capsule were produced by plants pollinated by O. bicornis from December to February. Finally, plants pollinated by Osmia bees produced more seeds than those hand-pollinated at all experimental months. These results showed that if the diapause of O. bicornis is successfully broken, this bee can be a very efficient pollinator in greenhouse environments, even during winter.","PeriodicalId":14941,"journal":{"name":"Journal of Apicultural Science","volume":"66 1","pages":"57 - 66"},"PeriodicalIF":0.6,"publicationDate":"2022-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47748402","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}

This study determined the impact of ambient (control) and simulated warmer (heating) climatic conditions on the microclimate of brood nest and gut bacterial abundance of two Apis mellifera subspecies i.e. A. mellifera ligustica and A. mellifera sinisxinyuan. For both subspecies, brood nest temperature and relative humidity under the heating treatment were significantly different (p≤0.001) than those under the control treatment. Quantitative PCR data revealed that the abundance of gut bacteria (16S rRNA gene copy numbers) of A. mellifera ligustica and A. mellifera sinisxinyuan larvae was significantly higher (P≤0.05), 1.73 and 5.32 fold higher respectively, during the heating treatment than those in control conditions. Although gut bacterial abundance of A. mellifera ligustica (1.67 × 107 copies g−1 fw) and A. mellifera sinisxinyuan (1.7 × 107 copies g−1 fw) larvae was similar during the control treatment, A. mellifera sinisxinyuan larvae exhibited three times greater gut bacterial abundance than A. mellifera ligustica during the heating treatment. Similarly, adult A. mellifera sinisxinyuan bees harboured significantly greater bacterial abundance during the heating treatment than control. These findings elucidate that climate warming may significantly affect the honeybee colony microclimate and their gut bacterial abundance. However, further studies are needed to better understand how gut microbial community may influence the learning, physiological and behavioural mechanisms of the host bees in a climate warming scenario.","PeriodicalId":14941,"journal":{"name":"Journal of Apicultural Science","volume":"66 1","pages":"15 - 27"},"PeriodicalIF":0.6,"publicationDate":"2022-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45499879","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}

Since HBV has the potential to treat some diseases, its quality and production conditions require a detailed investigation. The objective of this study is to understand how season, harvesting time (day or night), harvesting site of beehives (inside or entrance) and geographic location affects quality through the analysis of apamin, melittin and phospholipase A2 (PLA2) content. Each set of six colonies were used to understand the differences in these components when HBV is harvested in the daytime either from the entrance or inside of the hives and nighttime from the inside of the hives. The experiment also investigated seasonal differences as the samples were harvested each month from May to August 2019 in our apiary. Furthermore, the effect of geographic location on quality was examined through the comparison of the data obtained from twenty-seven samples collected by beekeepers using the same device, located in the Turkish cities of Manisa, Muğla, Balıkesir, Düzce and Mersin. The results demonstrated that statistically significant differences in the amounts of analyzed components were not dependent on harvesting time, collection site on the beehives or season. On the other hand, region samples significantly differed in the amounts of all three components, ranging from 1.28% to 3.81% for apamin, 19.51–64.03% for melittin and 7.22%–28.18% for PLA2. However, beekeepers’ improper practices during harvesting and storing might be the most critical parameters that determine the quality of HBV.","PeriodicalId":14941,"journal":{"name":"Journal of Apicultural Science","volume":"66 1","pages":"5 - 14"},"PeriodicalIF":0.6,"publicationDate":"2022-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43384647","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}

A total of 1650 worker bee samples (110 colonies) were evaluated with the forty-one morphological characters and 217 honey bee samples were analyzed via DNA sequencing of the tRNAleu-cox2 region. In this study, three different populations, Thrace (Tekirdağ, Kırklareli and Edirne provinces), Island Gökçeada, and western Anatolia were formed based on morphometrics, since the Marmara Sea has taken a very strong barrier role in this formation. The morphological similarity of the Thrace population was supported by the genetic analysis. The sequencing of the tRNAleu-cox2 region revealed twenty-two different haplotypes, sixteen of which are novel. The C2d, macedonica-like haplotype, was the most widely found haplotype (48%) all around the Thrace region. Along with the C2d haplotype, previously published C2s, C2v, C2i, C2j, and C2h haplotypes, and the newly found haplotypes were also observed but less frequently. In this study, Thrace honey bees were found to more similar to A. m. macedonica through the mtDNA sequence analysis, whereas carnica-like honey bees were only found near the Istranca mountain ridges, Kırklareli province and macedonica-like honey bees all around the Thrace region. According to our results, some of the Thrace honey bee populations may be both A. m. carnica and A. m. macedonica but the assignment to the latter subspecies seems more likely due to its geographic range.","PeriodicalId":14941,"journal":{"name":"Journal of Apicultural Science","volume":"66 1","pages":"67 - 83"},"PeriodicalIF":0.6,"publicationDate":"2022-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43473199","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}

Each of ten colonies were split into two colonies and placed in a meliponary, which resulted in ten queen-right mother colonies and ten queenless daughter colonies. We allowed daughter colonies to produce gynes, which then naturally mated with males of unknown origins. Six months later, five third-instar larvae from each colony were genotyped at six microsatellite loci. Four new alleles (12% of 33 alleles) were found in daughter colonies that were not present in any other mother colony. The Fst index showed no overall significant differences between mother and daughter colonies, indicating that they belonged to the same population despite the new alleles. Interestingly, nine queens were estimated to be polyandrous, with an average mating frequency of 1.3, unlike previous reports for this species. These results have implications for the fitness of managed stingless bee colonies and suggest that a better understanding of how gene flow is affected by human management practices would be beneficial.","PeriodicalId":14941,"journal":{"name":"Journal of Apicultural Science","volume":"65 1","pages":"291 - 301"},"PeriodicalIF":0.6,"publicationDate":"2021-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42459516","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 aim of this study was to examine the possible use of ultrasounds or microwave radiation to delay the crystallization of honey and to liquefy crystallized honeys while maintaining their biological activity. Lime, acacia and multifloral honeys obtained from a local apiary were used. Fresh honeys were pretreated through ultrasounds (40 kHz, for 5 and 20 min) or microwaves (800 W, 4 x 30s) in order to obtain samples U5, U20 and M, respectively. Experimental and control samples were stored for twelve months at room temperature (20±2°C) without light. Crystallized honey was liquefied through the same methods of ultrasounds (sample U5* and U20*) and microwaves (sample M*). Naturally crystallized honeys were used as the controls. For fixed (U5, U20 and M) and decrystallized (U5*, U20*, M*) honeys, the water content (refractometrically), antioxidant properties (DPPH method), total phenolics content (Folin-Ciocalteu method) and enzymatic activity (diastase, α-glucosidase, β-galactosidase and α-mannosidase) were determined. The analyzed physicochemical parameters for both fixed and liquefied honeys did not differ significantly (P>0.05) in comparison to the control honey. Moreover, the decrystallization process increased the antioxidant activity of all tested honeys. The smallest changes in honey properties to ultrasonic treatments were observed, and this method was recommended to delay the crystallization process and significantly accelerate the liquefaction time of solid honeys without compromising its quality.","PeriodicalId":14941,"journal":{"name":"Journal of Apicultural Science","volume":"65 1","pages":"243 - 253"},"PeriodicalIF":0.6,"publicationDate":"2021-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43140678","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}
