" Mylonapht " with negative results. The ends of the branches of 

 trees sprayed with kerosene soap emulsion withered in some cases, 

 while in June the pest reappeared, although in small numbers, both 

 on these trees and on those sprayed with Scalecide. The tips of the 

 branches covered with Aphids were then cut away and burnt, while 

 the thicker branches were sprayed with a strong jet of cold water, 

 and no Aphids were noticed afterwards. It is thus concluded that 

 under the climatic conditions prevailing in Poland, E. lanigerum can 

 be successfully controlled by these means.
