Soybean Pest Podcast
Still very few aphids in the soybean fields of Iowa. Drs. O'Neal and Hodgson give an update and discuss the likelihood of a soybean aphid outbreak later this summer. Also, Dr. Hodgson gives us an update of events where she will discuss recent research and new tools for pest management in soybeans.
Drs. O'Neal and Hodgson give a quick update on the status of soybean aphid populations in Iowa. They also review the other insect pests that may be out this time of year feeding on soybean leaves.
In this episode Drs. O'Neal and Hodgson discuss the low populations of soybean aphids in Iowa. Dr. Hodgson highlights upcoming meetings and workshops to learn more about soybean production and pest management.
Drs. Matt O'Neal and Erin Hodgson are back with their weekly podcast regarding the soybean aphid and other insect pests of soybeans. In this brief (~3min) episode we talk about the state of soybean aphids in Iowa and the midwest with a quick review of efforts to monitor aphid migration to soybeans.

Dr. Mary Gardiner, assistant professor at the Ohio State University, visited ISU and gave a seminar about her research on the ladybeetles. Ladybeetles can play a positive role by feeding on pest like the soybean aphid. Mary's research is focused on the exotic multi-colored asian ladybeetle. This species is a voracious predator of soybean aphids, but is also a pest in our homes and to grape growers. Mary is documenting the role landscape plays in the establishment of this species as part of her Buckeye Lady Beetle Blitz.

Matt O'Neal talks with Amy Asmus of Asmus Farm Supply to discuss outbreaks of aphids in cornfields around north-central Iowa. The two discuss what species of aphids are in corn and what impact they may have. Be prepared for more questions than answers as the scientist and crop consultant compare notes about this problem. For a more complete description of the aphids see Dr. Erin Hodgson's article in the Integrated Crop Management Newsletter (www.extension.iastate.edu/CropNews/2009/0807hodgson.htm)
Its mid-August and soybean aphids are starting to look white and small (yes, even smaller). Do they count? Are aphid populations still increasing? Why? Erin and Matt answer these questions and more.

Erin and Matt discuss the recent increase in aphid populations including winged aphids that are moving from field to field. We discuss what growers should consider when applying insecticide to soybeans when seeds are developing. We summarize a recent Integrated Crop Management newsletter articles on late season management of soybean aphids.

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
