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.

A comprehensive review of the honeybees of Africa on a subspecies as well as by country basis. Includes an updated multivariate analysis of the subspecies based on the merger of the Ruttner database (Oberursel) and that of Hepburn & Radloff (Grahamstown) for nearly 20,000 bees. Special emphasis is placed on natural zones of hybridisation and introgression of different populations; seasonal cycles of development in different ecological-climatological zones of the continent; swarming, migration and absconding; and an analysis of the bee flora of the continent. The text is supplemented by tables containing quantitative data on all aspects of honeybee biology, and by continental and regional maps.
