roztočíková nákaza včel  

DÉFINITION

  • A disease of unknown origin, which devastated British beekeeping in the early 20th century. Characterised by crawling bees, unable to fly, which died suddenly in large numbers. At first thought to be caused by Nosema, and then generally agreed to be due to tracheal mites. Now considered to have been caused by a combination of multiple factors, principally chronic bee paralysis virus, together with poor weather conditions, and an excess of bee colonies being kept for the amount of forage available.
