Soybean Pest Podcast
Today, Matt and Erin talk about the upcoming ESA meeting (Entomological Society of America) in Minneapolis next month. It's not too late to register for the meeting: http://entsoc.org/entomology2015. Matt also highlights an upcoming seminar about monarch butterflies in the ISU entomology department. Dr. Meron Zalucki, University of Queensland, School of Biological Sciences, Australia, is presenting on November 9. Come to listen in person or watch at your convenience here: https://www.youtube.com/channel/UCyJpsN5fR8Ia2WJNllyvB1Q.
The ISU Monarch Consortium is hosting Dr. Zalucki and have other research and outreach projects: http://monarch.ent.iastate.edu/.
Today, Matt breaks down a technical publication to Erin. This study evaluated the effect a lady beetle had on diamondback moth in Bt broccoli. Turns out, the presence of natural enemies can slow down the rate of Bt resistance. They talk about implications for this research in Iowa, specifically for corn rootworm in corn.

In this episode, Matt starts by sharing some of the night life stops in Dubuque, Iowa. Erin talks about common nuisance invaders moving into homes during this extended fall weather. Learn more about how to manage these pests here: http://bit.ly/1P3KcX2. For most of the time, Matt and Erin talk about a recent editorial letter in Nature Biotechnology (October 2015). The author(s) share a story of a recent scientist that accepted funding from industry and the unexpected implications from the public. Read the letter here: http://www.nature.com/nbt/journal/v33/n10/full/nbt.3384.html.
Today, Matt and Erin comment on a recent letter to the editor about too many "bees" on the ISU campus (see letter here: http://bit.ly/1LNbQGS). They talk about the real culprit, yellowjacket wasps, and why they may seem more abundant this year. Matt and Erin review the differences between bees and wasps, and why we probably don't have too many bees.
Today, Matt and Erin ask our 2015 Gunderson Memorial Lecture speaker, Dr. Dominic Reisig, a few questions about his research and extension program. Dominic is a field crop entomologist at North Carolina State University and has a wide range of responsibilities, for pest management including corn, soybean, cotton and wheat. Topics include stink bugs, kudzu bug, caterpillars (like Old World bollworm and corn earworm), and even soybean aphid.
In this episode, Matt and Erin break down a recent ruling to vacate the unconditional registration of sulfoxaflor. In other words, the EPA registration for sulfoxaflor, in products like Transform and Seeker, was overruled in U.S. court.

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.
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.
