SPECIAL NOTE TO SPECIALIZED AGRONOMY EXTENSION ADVISERS 



averal weeks ago, you were sent information about the locations of fields of corn stubble 

 a your area with high overwintering populations of European corn borers . We need your 

 jlp in following the development of corn borer in the state for the next several weeks, 

 cten, there are sufficient stalks left exposed, even if the field has been plowed or 

 isked. Keep track of the number of larvae, pupae, and empty pupal cases as you dissect 

 ie stalks until you count a total of 25 forms. You should be able to do this in 30 

 mutes to an hour, if the field still has sufficient borers. If you can get the reports 

 lto the mail by Monday or Tuesday of each week, this would be most helpful.
