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)

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. Please email us with your questions (oneal@iastate.edu or ewh@iastate.edu)

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.

Aphids are still hard to find, but that doesn't mean that Matt and Erin can't find something to talk about. We discuss spraying insecticides based on a calendar date as opposed to spraying insecticide based on need (i.e. aphids populations above a threshold).

Soybean aphids are picking up activity throughout Iowa; however, populations are still very patchy. Also consider other defoliators in soybean right now that might compound stress during pod set.
