Available in PDF, EPUB and Kindle. Book excerpt: Beekeeping within the ec is threatened by a disastrous mite pest. Since 1977 when varroa jacobsoni entered the federal repiblic of Germany it has already invaled greece, Italy and France. within a few years the entire mainland of the EC will tis problem. Because it is difficult to demostrate the initial infestation of a honeybee colony with varroa, it is almost impossible to obtain a reliable survey of the distribution of this mite. Many more countries may be infested at this moment. Therefore control measures have to be taken even before Varroa mites are found. The death of honeybee colonies follows within 3-4 years after infestation. This stage has been in the federal republic of Germany and Greece.

Download or read book Trends in Acarology written by Maurice W. Sabelis and published by Springer Science & Business Media. This book was released on 2010-11-16 with total page 511 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mites and ticks are everywhere and acarologists go after them – some explore their bewildering diversity, others try to understand their how and why. For the past 50 years, the International Congress of Acarology has been the forum for worldwide communication on the knowledge of Acari, helping researchers and students to look beyond their disciplines. Many mites and ticks are economic factors as they are pests of agricultural, veterinary and medical importance, and several species have become model organisms in modern biology. The 96 contributions to Trends in Acarology – reflecting fields as molecular biology, biochemistry, physiology, microbiology, pathology, ecology, evolutionary biology, systematic biology, soil biology, plant protection, pest control and epidemiology – have been reviewed and carefully edited. This volume contains a wealth of new information, that may stimulate research for many years to come.

This book was released on 1996 with total page 106 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aspects concerning the bionomics of the parasitic honey bee brood mite, Varroa jacobsoni Oudemans were investigated. Mite mortality is great during the winter season when the host colony is not rearing brood, appearing to be independent of the mortality of its host. In winter period, no significant association between the number of dead mites and the number of dead adult workers was observed. It appears that the mites are dying by factors other than the host death. Drifting drones facilitate the horizontal transmission of Varroa jacobsoni mites between colonies, especially in modern beekeeping in which managed colonies are kept similarly hived and close together. A great tendency of drones to drift among colonies was observed. A significant correlation was found in the rate of mites per drones and the number of drones in the colonies. It was concluded that the transmission of Varroa jacobsoni among colonies via drifting drones is a common mechanism for the transmission of mites. The relationship between mite load and the size of the honey bee brood host was investigated. The data showed significant statistical differences between the infestation rate of the mite that is, number of female mites per infested pupae and the size of the worker brood nest of its host. With a high number of worker cells in the colony, the mite load is lowered. Feeding activities of V. jacobsoni causes a great impact on A. mellifera colony survival not only through physical damage caused by this mite but also through transmission of various entomopathogenic agents responsible for the outbreak of secondary diseases in the colony. I concluded that mites fed on adult bees during summer time. It appears that the frequency of mite feeding on adult bees at this time is low, suggesting that probably the mite feeds only for maintenance and survival rather than for reproduction.
Download or read book Biogeography and Taxonomy of Honeybees written by Friedrich Ruttner and published by Springer Science & Business Media. This book was released on 2013-03-09 with total page 292 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
