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. For more information visit http://iowabuglife.blogspot.com/ for pictures and additional details about spider mites. For more info about managing crops and pests in this drought visit

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. For more info about insects this summer, see Dr. Hodgson's blog (http://iowabuglife.blogspot.com).

Hot weather isn't favorable for soybean aphid, so numbers are still down. But spider mites and other pests thrive in these conditions.

As we wait for soybean aphids to arrive, we discuss how the early and large outbreak of Japanese beetles in central Iowa may harm crop production. Dr. Hodgson discusses some options for preventing the beetles from clipping corn silk, a significant form of damage caused by these pests.

June is often a quiet month for insect pests but not this year as the Japanese beetle has emerged 2  to 3 weeks earlier then usual. So even though soybean aphids are uncommon right now, farmers may want to scout for this pest. We discuss what to look for and what the impact could be. To meet with Dr. Hodgson, consider joining her at the Crop Management Clinic (11-12 July) at FEEL. Visit this site for more information http://www.aep.iastate.edu/feel/cmc.html

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.

As soybeans reach the late reproductive stages the need to manage aphids decreases. However, aphids persist in soybean fields around the midwest. We discuss a couple factors that should be considered when applying insecticides this late in the year. Also, we re-count the spread of Japanese beetles in Iowa as a new herbivore of soybeans.

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.

Aphid populations continue to increase in Iowa. We discuss their trajectory and when/if insecticides will be needed. Also, new publications from Iowa State University are available for the soybean aphid and the brown marmorated stink bug. To purchase the id guide for stink bugs or the new soybean aphid field guide visit the ISU extension publication store (www.extension.iastate.edu/store). To learn where the brown marmorated stink bug is in Iowa visit www.ncipmpipe.org.

Soybean aphid populations reach threshold in Iowa and japanese beetles are becoming an increasing problem for both soybean and corn. In this episode we discuss both of these pests and the need to scout now to determine the need for an insecticide.  To learn more about Japanese beetles see Dr. Hodgson's latest article in the Integrated Crop Management newsletter (http://www.extension.iastate.edu/CropNews/2011/0722hodgson.htm).
