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 www.ncipm.org/traps/), 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.
