Drs. Matt O’Neal and Erin Hodgson created a podcast to promote IPM concepts, like identification, sampling, economic thresholds, and insecticide efficacy. They also talk about updates on invasive pests and regulatory news, and translate new research relative to insects in agriculture.

In this episode, Matt and Erin transition from providing weekly field crop pest updates to other topics of interest. They discuss the new assessment form provided by the Xerces Society to help farmers understand the value of beneficial insect conservation.

In this episode, Matt and Erin talk about end-of-season soybean aphid populations in Iowa. Matt also shares results from a recent CCA poll from ISU Sociologist J. Arbuckle. He summarizes perceptions about emerging concerns in agriculture.

Today is the first day of school at Iowa State and campus is buzzing. Matt and Erin talk about persisting soybean aphid populations in Iowa and why fields need to be scouted. If you have questions or ideas for sharing podcasts, please contact them (oneal@iastate.edu or ewh@iastate.edu).

If a soybean aphids could talk, I would imagine them screaming, " Stop touching me!". Many Iowan fields are infested with soybean aphid this summer. Erin and Matt talk about what to do when these increasing populations happen late in the season. A short conversation about aphids in corn also happens. Finally, they get diverted and talk about winged aphid formation based on several cues, like touching and predators.

In this episode, Matt and Erin start by talking about foliar insecticide sprays for soybean aphid. Erin has a large efficacy evaluation program and screens many different products every year. She publishes the results in a Yellow Book (see previous editions here: http://www.ent.iastate.edu/soybeanresearch/content/extension). Then Matt talks a bit about corn rootworm biology and why that might be important in Iowa soybean.

In this podcast, Matt and Erin talk about recent aphid developments in northern Iowa and southern Minnesota. Soybean aphid numbers are steadily climbing and aphids in corn are making a rare appearance this year. Foliar insecticides are starting to happen to protect yield. Also, Matt recently attended a USDA Corn Climate Change grant meeting and summarizes recent applied and modeling data for future corn production.

“Hanging around, nothing to do but frown, Rainy days and Mondays always get me down.” Karen Carpenter sang about this deadly combination and it’s effect on her emotions. Now, Matt and Erin pile on with a list of insect pests that are active in the state of Iowa. Thankfully, it is not all bad news as we review the biology and pest status of spider mites, soybean aphids and a mix of caterpillar species. We discuss how the weather can help determine if a spider mite outbreak is likely and some tips for dealing with one if it occurs. Matt reveals an upcoming gig in which he will speak at a “Conservation Biological Control Short Course” hosted by the Xerces Society for invertebrate conservation. This all-day event is on 21 August at the ISU Field Extension Education Lab. To learn more visit the website: http://conta.cc/1g9yZqI.

Today, Matt and Erin discuss recent soybean pest activity. Of special note, soybean aphids can be more easily found in northern Iowa and scouting fields is highly recommended. Also, green cloverworm is making a special appearance in a few fields. Matt wraps up the podcast by sharing a research update that involves collecting pollen from honey bees to see where they are feeding.

Today, Matt and Erin talk about an old pest that is new again. European corn borer is making a comeback in some non Bt-corn. Identification and management are important for timely foliar insecticide applications. Also, Erin saw a small plot with increasing soybean aphid populations - it was also noted in other research plots compared to last week. Lastly, they talk about the potential usefulness of UAVs for making management decisions in field crops. The link Matt mentioned: http://n.pr/1GjpPBx/.

Today, Matt is back from vacation and talks with Erin about the latest insect activity in Iowa. Soybean aphids can be found in northern Iowa, but at very low numbers. Japanese beetles are feeding in corn and soybean in central counties, and a mixture of caterpillars are feeding in soybean.
