The 2008 crop season has been unusual; not only has the weather been extreme, but the value of crops is higher than it has been historically. In the European Corn Borer Ecology and Management bulletin published in 1996 the economic injury levels for first generation European corn borer attacking corn were calculated for corn that sold for $2.50 per bushel. Now field corn can be sold for nearly three times that amount. How will this affect the number of larvae that should be present when it is decided to apply a control?
