Aphids on the rise, and rootworms, too!
Matt and Erin summarize the trend in soybean aphid populations for the midwest. They discuss other pest, include the corn rootworm and the reports of cornfields damaged by this pest. For more info on why this may happen in Bt-corn fields see http://bit.ly/16plxWm.
Also, for more info about how rotating crops is good for more than just managing rootworms, visit http://www.sustainablecorn.org/
Now it's cool, just the way aphids like it
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.

Matt's back and so are the JBs!
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).
The soybean aphid podcast is back for 2012!
Drs. Hodgson and O'Neal return with weekly updates on the insect pests attacking soybeans. This week we discuss the first reports of soybean aphids in Iowa, the growing risk for spider mite outbreaks, and an alarming change in the emergence of Japanese beetles.
Rounding third: covering the bases with late season aphid management advice
The growing season is coming to an end and aphids still persist in some areas. We discuss how insecticides may cause problems with spider mites, especially with the use of pyrethroid-based insecticides. Also look for updates regarding bean leaf beetle threshold calculator in the ICM newsletter next week. Thanks to Mike McCarville.
When to spray for aphids
We discuss the likelihood that aphid outbreaks will occur and when to spray aphid populations. Some agri-businesses are suggesting that aphids be sprayed when populations are lower than 250 aphids per plant. We discuss the value of such lower thresholds, as well as ways to detect other invasive insect pests of soybeans.
Aphid populations increase! No lie.
We share reports of aphid outbreaks in soybeans in MN. Numbers are up in Iowa. Also, have you noticed big, metallic green beetles? Japanese beetles are out in Iowa.
