Soybean aphid has been showing up in the upper mid-west for several weeks. This pest can be a big problem in soybean production, but has not historically been so in Kentucky. We hope, and in the short run expect, that this will remain the same, at least for 2009. It is however, important to remember that this pest can and does infest Kentucky grown soybeans. If its' biology and/or short term weather patterns change then we may see more of this pest than we wish.
As of this writing we have not found any soybean aphids in our sentinel plot system. The aphid suction traps in Lexington and Princeton have not caught any soybean aphids. Additionally, I have not received any reports from agents or consultants (who often find the first aphids).
So, at present wer are in good shape with reference to soybean aphid. I see no reason, except late plantings, to assume that anything other than the norm will occur this season. However, you should keep your eyes open! You are encouraged to report soybean aphid finds to email@example.com. I will use your information to keep us all informed.
