PHEFACE 



The contents of the following pages are largely based on a 

 series of lectures I gave at ttie Alabama Polytechnic Institute at 

 Auburn, Alabama in tne beginning of 1957. Tne text given here has 

 been restricted as mucn as possible to what cannot yet be found in 

 comprehensive textbooks or monographs. Instead it tries to give a 

 personal vision of nematode problems in Western Europe. Therefore 

 a discussion of laboratory methods which comprised part of the lec- 

 tures has not been included here. Without the help of demonstrations 

 no text on this subject would be better tnan J. B. Goodey : Labora- 

 tory Methods for Work with Plant and Soil Wematodes, to which the 

 reader is referred. Also the workshop manuals give a good accoiuit 

 of these techniques. 



I wish to express my most grateful acknowledgement to those 

 who arranged my six months visit to the Southern States of the U.S. 

 This visit has widened my experience and insight in the general 

 problem.s of plant nematology both m tne United States and Europe 

 tremendously. 



I also wish to express my most sincere thanks to all ' hose 

 Ameroian colleagues who, by their kind and abundant assistance in 

 my travels and their great hospitality, made this trip a most agree- 

 able and useful one. In particular, I want to mention Dr. Eldon J, 

 Cairns who took off my shoulders almost every burden involved in 

 stajdJig in a foreign country with a family and organizing a travel- 

 ing schedule. 



My famiJy and I wish to express our great appreciation for the 

 kind help in every-day life matters we received from Dr. and Mrs. 

 E. J, Cairns, Ilr. and Mrs. Norman Mmton, and many otner Auburn in- 

 habitants .
