The луогк on the central problem has been already initiated. Of course, 

 beside the main problem the special problems of each disci2)line will be solved. 



The necessit}" of the full development of the basic entomological research 

 and the connected enliancement of general dynamic disciplines is not a specific 

 problem of Czechoslovak entomology, but it appears as a logic consequence 

 of the progress in general in many other countries, too. It is a direction in which 

 the world entomology progresses. Most renowned scientific workers are present 

 here who have great merits in this scientific progress. 



In endeavour to give a support to this development the Czechoslovak 

 Academy of Sciences has organized the Symposium. We shall be very happy 

 if our contribution will be a step forward.
