Today, Matt and Erin talk about the recent EPA proposal to revoke all tolerances to chlorpyrifos. This insecticide is an option in corn and soybean in Iowa and restricting or removing the use could have potential implications for field crop pest management. Matt shares a paper that shows a decrease of chlorpyrifos in corn but relatively steady use in soybean (doi:10.1088/1748-9326/10/9/094016). He isn't sure if revoking the use would have an immediate impact, but Erin offers a Coke analogy to say otherwise.

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. Find the form here: http://www.xerces.org/wp-content/uploads/2015/07/HAG_BeneficialInsects_June2015_web.pdf

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).
