The embryonic development of Varroa jacobsoni Oudemans 1904 (Varroinae, Mesostigmata)

摘要

for the first time the authors document the existence of different embryonic stages of Varroa jacobsoni OUDEMANS 1904 the honey bees mite. The outstanding peculiarity of Varroa s development is demonstrated by the fact, that primarily a sixlegged, and later an eightlegged immobile embryo is formed, from which finally a mobile protonymph originates. A mobile and free living sixlegged larva does not occur, and this contrasts to the development in related mite species.
