The micro-ornaraic department of Zeiss, Jena, under Dr. Trapp, is having diffi-
mnltles with a currant research project involving photo ;ro'aphs of a certain un -
i tez:',ified mite. This nits, which in a form of parasite, is usual]] .fex?red
to bar Zeiss personnel uorlcin on the problem as the clover rite, appears in
s,apgo nuubern in clover fields and is not 'ia1T.L#ul to the clover. Howo'ior, it
i-e s.iid to be h. ,7hly -lestri-Lcti.ve of potato plants. In the latter tart of
ku .vit 1950, Zeiss Tt.ras o1Y1ersd to Hake photographs of the biological 17ftavior

f'i_nt:i is havin7 difficulties with the task because the available instruments
rio not have the necessa lir,htinr; arrangomonts for biological work. Thez.~-
toova,, hotnvex, established that the damage caused by the mite occurs as soon
nn the errs are laid. These e -7s are laid sinsrly on the -rper and on the lor;rsr
surface of the .eaves. Thereupon the leaf begins to shrivel and curl, iIoa,ever,
