Abstract

There have been reports of aphids feeding on lower corn leaves this week. In July, I wrote an ICM article about corn leaf aphid thresholds prior to tasseling; however, there is still some concern about economic loss in August. People have noticed aphids moving down the plant and forming colonies on the stalk. Many are wondering if they are corn leaf aphids or something else? There are at least two different species that can be found in corn this time of year, but the identification may not be critical to management.
