Description: 

In the last episode of season 7, Matt and Erin talk about two new insecticide options for soybean aphid in Iowa. Movento and Sivanto by Bayer CropSciences are products that target fluid-feeding pests, like aphids, and are considered reduced-risk options compared to broad spectrum insecticides. Movento is a Group 23 and Sivanto is a Group 4D. To learn more about these insecticide groups, visit the IRAC website.

Description: 

It's a new beginning for the podcast - Season 8 starts today! Matt and Erin have a bit of random conversation at the beginning like usual. But they eventually provide a summary of the recent new of an organophosphate, chlorpyrifos. The EPA has been dealing with a petition to revoke tolerances for this widely-used insecticide. The EPA will not move forward with restricting chlorpyrifos in any crop; this could be important as farmers make product choices for 2017. Erin wrote a recent ICM Blog about it. Matt shared updates about his recent travels to the S1055 Soybean Entomology Working Group meeting in Memphis where he compares soybean production in the North Central Region to the South. Surprise - it's a lot different! Erin wraps up by providing overwintering mortality predictions for bean leaf beetle. The 2016-2017 winter was moderate and about half of the beetles are expected to survive. Read more in her recent ICM News article

Don't freak out (about a few aphids)

Description: 

Today, Matt and Erin cover a lot of topics. First, Erin summarizes her recent trip to Indianapolis for the 2017 North Central Branch ESA meeting. Lots of interesting papers and posters were presented this week. Also, the first confirmation of soybean aphid in Iowa happened again this week. It is typical to find aphids during early June in vegetative soybean, so listeners shouldn't be too concerned at this time. Other pest activity updates include more black cutworm and armyworm, plus a few bean leaf beetles and slugs. Matt follows up on the slug conversation by highlighting a recent interview with Penn State entomologist, John Tooker. As a follow up to the IRAC discussion a few episodes ago, Erin reminds everyone that the organization puts out a few helpful references on insecticide modes of action and resistance management. 

Two events of interest coming up:

Pollinator Fest at Reiman Gardens is on June 24. It's free this year, so bring your family for some fun hands-on activities centered around pollinators. 

Matt and Erin are organizing a field day with Greg Tylka on August 17. The event is at FEEL near Boone, IA and registration is open now

Description: 

Today, Erin is without her podcasting bestie, Matt. She summarizes the activity of a few field crop pests in Iowa. First, she mentions Japanese beetle is active in soybean now and will move to corn with the emergence of silks. There are also European corn borer egg masses and small larvae in non-Bt corn now. You can access a free publication to learn more about scouting and management of ECB. Erin also gives an update on thistle caterpillar and soybean aphid from the last episode - both pests are still active right now. Finally, she highlights potato leafhopper as an occasional pest of soybean and alfalfa. You can register for some upcoming demonstration events at FEEL for July 12 (Diagnostic Clinic) and July 13 (Management Clinic) right here

Description: 

Matt and Erin were supposed to be in Savannah, GA for a soybean symposium this week. But due to Hurricane Irma, the conference was canceled and they created a bonus episode of random topics. Soybean is quickly maturing throughout Iowa and insects are making preparations for the winter. Matt summarized a last-minute soybean research symposium recapping some of the presentations planned for the Georgia gathering. Both Matt and Erin noticed a lot of wasp activity around human structures and Matt explained they lose their social structure this time of year. Erin thinks she might have Lyme disease and will update listeners on her progress the next episode (teaser!). ISU faculty member, Ryan Smith, shared the blacklegged tick is expanding range in Iowa and the proportion of infected ticks is increasing in Iowa (see this survey summary for more details). Dr. Smith also said there are 195 confirmed cases of Lyme disease in Iowa so far this year. Finally, Matt talks about another great F.I.T. of Ward Kimball, creator of Jiminy Cricket.

Description: 

Today, Matt and Erin cover a wide range of topics. First, there are two entomologists interviewing for ISU president: Sonny Ramaswamy and Wendy Wintersteen. But the conversation is quickly diverted into talking about why entomologists make good leaders. Matt has another F.I.T. that includes a reference to Hogwarts. Tom Saunders named a new parasitoid wasp species after Lucius Malfoy, a character in the Harry Potter series. The new wasp was named Lusius malfoyi. Erin asks Matt about fall nuisance invaders around Ames, including multicolored Asian lady beetles, minute pirate bugs, and brown lacewings. Erin gives a shout-out to an insect-related podcast, Arthropod, from the University of Nebraska-Lincoln. This interesting series goes in-depth on insects and closely related species (e.g., painted lady butterflies and brown recluse spiders). Lastly, they are spreading the word about a fundraiser for BugGuide - help them meet their goal of $15,000!

Matt and Erin just got back from the Annual Entomological Society of America meeting in Denver and their brains are full! They summarize some of their favorite presentations and other highlights from the meeting. Specifically, Matt enjoyed a presentation by Cornell student Maxwell Helmberger who used entomopathogenic nematodes to manage grubs in turf. Maxwell has a YouTube channel with some fun animations!

Today, Matt and Erin bounce around a few topics of insect-related news. The black flies and mosquitoes have been especially aggressive in central Iowa this week. Erin summarizes field crop pest activity in central and southern Iowa, mainly some caterpillar feeding in corn and bean leaf beetle feeding in soybean. Matt's F.I.T. is somewhat random, but eventually ties it together with an insect.

Description: 

In this episode, Matt and Erin talk about randomness for the first 4 minutes (like usual). But they eventually move into recent insect activity in Iowa. The black flies, sometimes called buffalo gnats, are especially active this year and are aggressive blood feeders. It's hard to be outside the last two weeks because the females are swarming and causing painful bites. Matt noted an absence of soybean aphid activity on buckthorn, the overwintering host. They are unsure what this means for colonization timing and dynamics on soybean this summer. Matt presents a timely and interesting F.I.T. that combines soccer, Midwestern history and entomology.
