Abstract

Large amounts of acute paralysis virus (APV) were extracted from dead, field-collected samples of European honeybees (Apis mellifera) from Russia and German Federal Republic. Virus isolates were compared to the British type strain. Particles of the three isolates were physically indistinguishable and closely related serologically, and each produced three well-defined protein bands of apparently identical mol wt on SDS polyacrylamide gels. In Britain APV has never been found to be associated with mortality in nature. In both Russia and Germany the occurrence of APV in dead field bees and brood was associated with infestation of the colonies by the mite Varroa jacobsoni. The possible role of the mite in APV infection of honeybees is discussed.
