Soybean Pest Podcast
Erin and Matt discuss the recent cool temperatures forecasted for the last week of July and the implications for soybean aphid populations in Iowa. We also discuss the recent emergence of bean leaf beetles and observations about the Brown Marmorated Stink Bug.

It's hot! But we can still talk about aphids and other insect pests. It is a quiet week for soybean pests, but things are getting active in corn. We talk about what to look for when it comes to silk feeders. For more details about rootworms, a silk feeder and rootfeeder, look up Erin's recent factsheet. https://www.ent.iastate.edu/dept/faculty/hodgson/files/ul/CRW%20management%202012%20final.pdf.
At the end, Matt talks about a recent blog that summarizes his work on bees in soybean fields, http://www.agriculture.com/farm-management/conservation/bees-in-bes-qa-with-matt-oneal_556-ar32490.
Erin Hodgson and Matt O'Neal return to talk about insect pests of soybean in Iowa and the greater midwest. On today's episode, the return of the soybean aphid, the japanese beetles and a variety of uncommon insects that feed on soybean plants and other crops (stink bugs, celery leaf tier, and colapspis beetles).
This week, Erin Hodgson talks about confirming soybean aphid in Iowa, Minnesota, Michigan and Wisconsin.
The 2013 season of podcasts begins with a short recap of pest activity in Iowa.
Most of the state is approaching the seed fill stage (R5), indicating the end of profitable yield returns with an insecticide application. Watch a short video about spider mite management here: http://bit.ly/NdDj6c
Soybean aphid populations remain low but first generation bean leaf beetles are out i some areas this week. Spider mites are still the primary problem, and we encourage scouting to protect yield.
Although soybean aphid has been a relatively low threat this year, drought conditions have been a perfect storm for spider mites. We encourage people to scout fields now to fully protect yield.
Drought conditions continue for all of Iowa, setting the stage for spider mite outbreaks. Drs. O'Neal and Hodgson discuss the challenges of managing this pest.

Its Friday the 13th and farmers have much to worry about. But despite the record breaking temperatures and drought, there is some good news. We discuss the lack of soybean aphids throughout most of Iowa. However, there are other insect pests that growers should be scouting, including japanese beetles and spider mites.
