Mr. G. A. Dean: It seems to me the more we study the activities 
and habits of the European corn borer, the more we are convinced that it 
is an insect of major importance, or at least the indications are that where 
this insect becomes establishdin the great com belt of America it would 
do a large amount of damage unless farm practices different from those 
that are now used are put into operation. I think we are all convinced 
that the corn borer problem is not one of only the entomologists and 
agronomists located in the infested states, but is also one in which every 
entomologist and every agronomist in all the corn producing states 
should be interested. Since it is only a question of time until the corn 
borer reaches your state, it should behoove every entomologist of the 
corn producing states to cooperate with his agronomist in an effort to 
practice a type of agriculture that will reduce the injuries to the least 
possible minimum. I hope some of the entomologists of the corn states 
will be interested in this problem to such an extent that they will be 
willing to come to Ohio next spring and assist us with the clean-up 
campaign that we are attempting in the infestation bordering on Lake 
Erie. I can assure you that an invitation will be extended and a 
most hearty welcome given any one that can be present. 
While I am speaking of the corn borer, there is one criticism or a 
statement that has been made by two or three concerning the corn 
borer work. They have noticed in some of the published papers on the 
investigations in Canada and the States, and also in conversation with 
these workers, that there is apparently some disagreement in some of 
the recommendations and they wonder why we do not get together in 
this matter. I want to state very emphatically that the Canadian 
workers and the workers in the United States consider the corn borer 
problem as a big cooperative project and in every respect there is an 
exceptionally fine spirit of cooperation. During the past year there have 
been several conferences by all the investigators in the principal infested 
districts. Nothing is withheld, but on the other hand, one investigator 
knows just what the other is endeavoring to do. The results ac- 
complished and the future plans of investigation are discussed. In 
my opinion there are no more differences or statements are no more 
conflicting in the results secured and the recommendations made by the 
workers of Canada and the States than any state entomologist would 
find in a state-wide entomological investigation conducted in his own 
state. If you will take into consideration that the corn borer in Canada 
and in Ohio is one-brooded and infests only a few different plants, while
