Interview with Dominic Reisig Sep 21, 2015

Show notes

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.

EPA ruling transforms neonicotinoid registration Sep 14, 2015

Stop touching me! Aug 18, 2015

Show notes

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.

What do aphids and rootworms have in common? Aug 12, 2015

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.
