Spotty aphid outbreaks continue

Erin and Matt report on observations on aphid populations around Iowa from the week of August 3-7.  We discuss the continued production of winged aphids, their capture in the suction trap network (visit it at https://suctiontrapnetwork.org/about/), and the changing appearance of aphids in the field (winged, wingless and white dwarves).  If you have questions, please post them at www.soybeanaphid.info.
