Abstract

Cowpea aphids are a recent addition to the alfalfa fauna of Iowa with our first damaging populations found in northwestern Iowa in late July 2002. Since then they have sporadically caused damage, mostly during dry conditions, but no damage has been widespread across the state. This year Kevin Black, agronomist with GROWMARK, Inc. in Illinois, reports large populations of this insect, plus pea aphids, in numerous fields along the Interstate 70 corridor.
