Studienarbeit aus dem Jahr 2018 im Fachbereich Biologie - Krankheiten, Gesundheit, Ernährung, , Sprache: Deutsch, Abstract: The study was conducted in East Wollega Zone, Oromia Regional State, Ethiopia, from December, 2016 up to August, 2017 to determine the prevalent and incidence rate of honeybee disease and pests. Questionnaire survey and laboratory diagnostic methods were used for the study. The questionnaire was administered to 146 beekeepers (97,1% males)and two honeybee colony samples from each beekeeper totally (292 honeybee colonies) were collected from transitional and frame box hives for laboratory diagnosis. The honeybee samples collected were examined in laboratory for the prevalent and incidence rate of honeybee disease pathogens and pests. Majority of the respondents started beekeeping after 2010 (28.03%) by catching colonies as honey bee colony source (54.8%). The major dearth period of the area was late march to early may. The trend of beekeeping in the study area was shifting from traditional to modern beekeeping and the trend of honeybee colony and its yield was decreasing due to honeybee health problem of the area (pests, predators, pathogenic disease, high cost of bee equipment and agro-chemical application). In the study area the major pests and predators considered as challenges were ants, beetles, wax moth, varroa destructor and some predators like honey badgers, bee eater birds, dead head hawks moth, lizards, wasps and birds respectively. Varroa, Nosema, Amoeba and chalk brood disease were confirmed while tracheal mite, stone brood, Ameriacan and Europian foul brood did not confirmed during the study period. The prevalentand incidence of varroa destructor was higher in dry season than wet season while the prevalent/incidence rate of nosema and chalk brood disease was limited during dry season. Amoeba disease was distributed in both seasons.For the reason of time restraint in this study area, farther study on economic threshold of honeybee disease and pests is suggested by monitoring throughout the year.

Public Health Significance of Urban Pests available in PDF, EPUB and Kindle. The second half of the 20th century and the beginning of the 21st century witnessed important changes in ecology, climate and human behaviour that favoured the development of urban pests. Most alarmingly, urban planners now face the dramatic expansion of urban sprawl, in which city suburbs are growing into the natural habitats of ticks, rodents and other pests. Also, many city managers now erroneously assume that pest-borne diseases are relics of the past. All these changes make timely a new analysis of the direct and indirect effects of present-day urban pests on health. Such an analysis should lead to the development of strategies to manage them and reduce the risk of exposure. To this end, WHO invited international experts in various fields - pests, pest-related diseases and pest management - to provide evidence on which to base policies. These experts identified the public health risk posed by various pests and appropriate measures to prevent and control them. This book presents their conclusions and formulates policy options for all levels of decision-making to manage pests and pest-related diseases in the future. [Ed.]

Biogeography and Taxonomy of Honeybees available in PDF, EPUB and Kindle. Honeybees are as small as flies or as large as hornets, nesting in nar row cavities of trees and rocks or in the open on large limbs of trees 30 m above ground. They occur in tropical zones and in the forests of the Ural mountains, they survive seven months of winter and even longer periods of drought and heat. Historically, they lived through a extended time of stagnation in the tropics from the mid-Tertiary, but then experienced an explosive evolution during the Pleistocene, re sulting in the conquest of huge new territories and the origin of two dozen subspecies in Apis mellifera. This vast geographic and ecologic diversification of the genus Apis was accompanied by a rich morphological variation, less on the level of species than at the lowest rank, the subspecies level. Variation being exclusively of a quantitative kind at this first step of speciation, tradi tional descriptive methods of systematics proved to be unsatisfactory, and honeybee taxonomy finally ended up in a confusing multitude of inadequately described units. Effective methods of morphometric-sta tistical analysis of honeybee popUlations, centered on limited areas, have been developed during the last decades. Only the numerical characterization of the populations, together with the description of behavior, shows the true geographic variability and will end current generalizations and convenient stereotypes.
