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.

For the past 5 years, we have evaluated insecticides for managing soybean aphids. The most recent report can be found at our website www.soybeanaphid.info. After applying insecticides as part of our 2009 insecticide evaluation, Erin and I discuss some issues to consider when selecting an insecticide

In this extra podcast, Matt O'Neal discusses a recent change to the Iowa bee rule with Betsy Buffington. Betsy works for The Pesticide Applicator Training Program at Iowa State University. She has created a publication about the bee rule, which can be found at the Iowa State University Extension publication office as PAT 47.

For the week of August 3, 2009, Drs. Hodgson and O'Neal discuss scouting reports from the previous week indicating increases in aphid populations.   In our longest podcast to date we discuss several issues growers should consider with regard to spraying insecticide for soybean aphids, including the potential for spider mite outbreaks.

For the week of July 27, 2009, Drs. Erin Hodgson and Matt O'Neal review reports and data on soybean aphid populations from Iowa and the midwest. Although large populations can be found, many growers are reporting low populations with less than 50% of the plants infested with aphids. Also, Erin discusses reports of soybean defoliation by insect pests that are not aphids.

For the week of July 20, 2009, Drs. Erin Hodgson and Matt O'Neal discuss the state of aphid populations in Iowa.  Aphids are now well established in many fields but at low populations.  We discuss factors that can contribute to the likelihood of an outbreak.  Also, Erin and Matt make a joke about aphid perspiration.

In this edition, Dr. Erin Hodgson is introduced. She is the new assistant professor in the Department of Entomology at ISU with extension and research responsibilities focused on corn and soybean production. Dr. Hodgson's Ph.D. was spent studying the soybean aphid and how best to scout for it. She describes some of the work she is doing this summer, helping growers manage insect pests in soybean fields.
