Available in PDF, EPUB and Kindle. Book excerpt: The wintering of honey bee colonies in an environmentally controlled building was undertaken using various hive preparations. The size of the hive to be wintered, the age of the queen and the food given to the bees in the fall were examined. No significant differences were found in the rate at which food was consumed by the bees between treatments with single chambered hives or between treatments with double chambered hives. However, the bees in double chambered hives consumed more food over the winter storage period than did the bees in single chambered hives. Syrup appeared to be a good substitute for honey as a winter food for the bees. Nosema disease occurred in many of the wintered hives, with the majority of the hives sampled having infections ranging from 0-10%. No correlation was found between the hive treatments and the occurrence of Nosema apis. Dead bees infected with N. apis were found to contaminate a water supply. especially if the bees were heavily infected. Water consumption by the bees during the winter storage period was extremely variable. It was found that many colonies consumed water, but that the level of nosema infection in the colonies had no bearing on the amount consumed. Honey bees wintered indoors yielded colonies the following year which were similar in population to those wintered outdoors. The requeening of some of the colonies was done too late in the year to be successfully evaluated. The drifting and loss of honey bees after they were removed winter quarters was examined. Drifting occurred in both an eastward and westward direction, with no pattern being evident. The loss of bees from the hives was initially quite substantial, but lessened with time.

Available in PDF, EPUB and Kindle. Book excerpt: An insulated indoor wintering facility was built to accommodate up to five hundred and twenty single brood chamber hives. The building contained four separate chambers, each individually heated and ventilated. Two hundred and twenty-five colonies were prepared and wintered indoors; seventy-five colonies in each of the three chambers during the winter of 1976-77. A variety of treatments were used to test the effects of colony size, time of requeening, and food supplies on winter survival of honey bee colonies. Data were collected on colony weight loss and colony mortality during the winter. Treatment did not have a significant effect on mortality. There was no significant difference in morality among the six treatments performed. There were significant differences in weight loss among the treatments and groups prepared. Differences were attributed to treatment and indoor conditions caused by the building construction and position of the hives within the building. Comparisions were made between indoor wintered colonies, outdoor wintered colonies, and package bee colonies in the following spring and summer of 1977 on the basis of brood production, adult population and honey production ... Outdoor wintered colonies had the highest brood production, largest adult populations and produced the most honey ... Samples of adult bees were taken from indoor wintered colonies, outdoor wintered colonies and package bee colonies during the spring and summer and were analyzed for Nosema disease. Indoor wintered colonies were found to have substantially higher levels of Nosema disease than outdoor or package colonies during the early spring. The level of Nosema disease decreased dramatically as the season progressed.

This book was released on 2012 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excessive honey bee colony losses all over the world are believed to be caused by multiple stressors. In this thesis, I characterized and quantified pathogen levels in honey bee colonies, studied their interactions with each other and with their associated parasite vectors, examined factors that influence their combined impacts on honey bees and developed methods to manage honey bee viruses so that colony losses can be minimized. My baseline study of virus prevalence and concentration in healthy and unhealthy (showing visible signs of disease) colonies in Canada showed that seven economically important viruses (DWV, BQCV, IAPV, KBV, SBV, ABPV, and CBPV) were all widely distributed in Canada. Differences in concentration and prevalence of some viruses were found between unhealthy and healthy colonies but these differences may have been due in part to seasonal or regional effects. Studies of the impact of viruses on worker bee populations over winter showed different factors were correlated with bee loss in different environments. Spring concentrations of DWV and mean abundance of Varroa (Varroa destructor) were positively correlated with bee loss and negatively correlated with spring population size in outdoor-wintered colonies. Fall concentration of IAPV was negatively correlated with spring population size of colonies in indoor-wintering environments but not in outdoor-environments. My study showed that it is important to consider location of sampling when associating pathogen loads with bee loss with Nosema and BQCV. Seasonal patterns of parasites and pathogens were characterized for each wintering methods (indoor and outdoor). My results revealed lower ABPV and Nosema ceranae prevalence and lower DWV concentration in genetically diverse than genetically similar colonies. I showed that within colony genetic diversity may be an important evolutionary adaptation to allow honey bees to defend against a wide range of diseases. In laboratory studies, I showed that feeding DWV to larvae in the absence of Varroa causes wing deformity and decreased survival rates of adult bees relative to bees not fed DWV. Finally, I showed that RNA silencing can be used to reduce DWV concentrations in immature and adult bees, reduce wing deformity in emerging adults, and increase their longevity relative to controls.

Download or read book Nosema Epidemiology and Control in Honey Bees (Apis Mellifera) Under Canadian Prairie Conditions written by Rosanna N. Punko and published by . This book was released on 2021 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Honey bees (Apis mellifera) are vulnerable to many diseases, including two species of the fungus Nosema, namely Nosema apis and Nosema ceranae. Nosema ceranae appears to be replacing Nosema apis, but its epidemiology, responses to drug treatments, climate, and wintering methods, and impact on colony productivity and survival are poorly understood. This study aimed to determine the seasonal pattern of Nosema abundance in two Alberta locations using indoor and outdoor wintering methods and the impact of Nosema on honey bee colony population and survival. This study also assessed the effects of spring and fall fumagillin treatment on spore abundance and colony productivity and mortality. Colonies that were naturally infected with Nosema had predominantly N. ceranae, but some had both N. ceranae and N. apis. Nosema ceranae had high spore abundance in spring, declining to low levels in the summer and fall. There was no clear pattern for differences in Nosema abundance between locations. Colonies that were wintered indoors had one-fifth the probability of mortality at similar Nosema abundance and more rapid spring population build-up than outdoor-wintered colonies. This suggests that the mitigation of temperature stress associated with indoor wintering reduced the impact of Nosema infections on colonies more than any potential benefits associated with late winter cleansing flights. Consequently, the existing Nosema threshold should be lower for outdoor-wintered colonies than those wintered indoors. Average Nosema abundance in the spring was a significant predictor of end-of-study winter colony mortality, highlighting the importance of spring Nosema monitoring and treatments. Fumagillin treatment in the spring and/or fall reduced Nosema abundance but did not eliminate the infection, making continued monitoring necessary. Honey bee colony population was improved by spring treatment, but not consistently between locations and years, possibly due to the late treatment application at a lower dosage than the label recommends. Previous spring and/or fall fumagillin treatment did not reduce spring Nosema abundance or increase colony population in the following spring. Therefore, to maintain low spring N. ceranae abundance, colonies should be treated in the spring even if treated in the previous fall. Treating with fumagillin in both the spring and fall increased colony survival in one of two years.

This book was released on 1979 with total page 358 pages. Available in PDF, EPUB and Kindle. Book excerpt: Each year an increasing number of beekeepers are overwintering wintering their honey bee colonies for economic reasons. Thus, there is a great need for a reliable supply of queen honey bees for these colonies. In an attempt to solve some of the problems associated with queen availability, the following four aspects of queen rearing and queen supply were examined; (1) spring queen rearing in the laboratory using caged worker bees, (2) a comparison of spring reared queens from British Columbia with spring reared queens from the United States, (3) queen rearing during the summer in Manitoba, and (4) studies in the orientation of queens during orientation and mating flights. Caged worker bees that had been confined to hives throughout the winter did not accept grafted larvae or nourish accepted larvae as successfully as did caged overwintered worker bees that had taken recent "cleansing" flights... The introduction of virgin queens to queenless colonies was most successful when the queen was first caged in the colony for 24 hours and then upon release was sprayed, along with its surrounding workers with a sugar syrup, vanilla mix. Under some test conditions, queens were found to make orientation errors and enter the wrong colony. This usually resulted in the queen being attacked or expelled from the colony. Various orientation cues (i.e. landmarks) appeared to reduce orientation errors of the queens to a marked degree.

This book was released on 2017 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Honey bees ability to overwinter in northern environments is affected by not only the populations of bees, but also their interactions with disease and environment. In this paper 48 honey bee colonies were treated in a 3X4 factorial study design using repeated measure over time. Three treatment dates, early, mid and late autumn and three acaricides and a non treatment control were explored for their effect on the timing, duration and effectiveness of Varroa mite treatment, as well as the effects on the population structure and dynamics of the honey bees. Timing of treatment was less important than the type of acaricide used and there was effects to the make up of the populations as a result of the treatments.

Book excerpt: Excerpt from Wintering Bees: An Exhaustive Treatise of the Subject Covering Both the Outdoor and Indoor Methods The matter for this booklet is taken from the article on wintering, in the author's larger work, the A B C and X Y Z of Bee Culture. Some new matter, however, has been added, covering the subject of feeding and brood-rearing in mid-winter while the bees are in the cellar. A new chapter on the importance of windbreaks has also been added. The author now believes that a suitable form of windbreak for outdoor bees is a vital and important element in successful wintering, and has, therefore, given this phase of the matter the consideration it deserves, in this little work.
