Abstract

Last July, Joel DeJong, ISU field specialist-crops, and I visited an alfalfa field near LeMars (western Iowa) that had large populations of blackish aphids. This year, Brian Lang, ISU field specialist-crops, reports finding large populations of this dark aphid near Decorah (northeastern Iowa). I suspect that these aphids are cowpea aphids, Aphis craccivora, based on their color.
