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

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

Finding more aphids, being malaise, and getting F.I.T.

Description: 

In this episode, Matt and Erin start off with talking about the hot weather in Ames. A local rain shower will help lawns and crops. Erin shared some updates on soybean aphid in Iowa. A few more reports are showing up from the lab as they visit various research farms. The percent infested plants is higher than in the past few years, so scouting in highly encouraged this summer. Both have noted aphids around the yard and on campus this month, too. Matt wants to try out a new segment called F.I.T. (fun insect trivia). He asked me about how the malaise trap was named and Erin was kinda right. Erin also had a F.I.T. about determining the sex of Japanese beetle. It wasn't nearly as interesting as Matt's story and maybe not even that important to know. Erin also noted Japanese beetles are emerging in southern Iowa and corn rootworm egg hatch is peaking around Iowa this week. If you live in north-central Iowa, plan to attend a field day at the ISU Northern Farm near Kanawha.

Description: 

In this mid-June episode, Matt and Erin start off by summarizing current soybean aphid activity around the state of Iowa. Populations are showing up over much of northern Iowa the last two weeks. Some fields have approached infestations ranging from 10-50%, although the density per plant remains low. Under ideal conditions, these populations could exceed the economic threshold in a few weeks. Brian Lang also found an aphid mummy, which is also early compared to most summers. Erin talked about a new publication for European corn borer that is available at the ISU Extension Bookstore. The 12-page pub reviews identification, life cycle, plant damage, scouting and treatment recommendations for this devastating pest. In their new segment, Matt talks semantics about how to spell one of the most widely recognized insects in the world.

Description: 

It seems like a long time since the last episode and that's because it was! Matt and Erin are back to talk about pest updates in Iowa. Drought stress throughout much of the state has been ideal for twospotted spider mite. Erin reports Some injury has been observed in corn and soybean this summer. Treatments are going on now throughout some southern Iowa counties. In addition, soybean aphid continues to be an erratic pest. Some populations are building up in northern Iowa counties, but most fields are not reaching the economic threshold in July. Matt elaborates about high numbers of Japanese beetle and they talk about the use of pheromone traps as a management tool. Finally, Matt talks about a new Science research paper that has inconsistent data on the effect of neonicotinoid seed treatments on wild and managed bees in Europe.

Matt and Erin took a short podcasting break but are back to summarize late season soybean pest activity. Erin talks about a slight resurgence of soybean aphid populations in northern Iowa. Read more about treating at full seed set in a recent ICM Blog. Erin also recommends scouting in late August/early September for second-generation bean leaf beetles, as feeding injury to pods and seeds could be significant. Matt has noticed perhaps early field senescence in some commercial fields in Iowa. He also took a trip to Mississippi to see soybean production and learn more about pollinator protection. This podcast also features a F.I.T.!

Description: 

Matt and Erin talk briefly about resurging soybean aphid populations around northern Iowa. In some fields, aphid numbers have increased as fields reach full seed set. They also talk about 2 videos of potential interest to everyone. The first video shows off the extremely high numbers of mosquitoes in Texas due to Hurricane Harvey. The second video talks about the importance of Bt resistance management of insects. Finally, Matt shares a F.I.T. and art at Iowa State University.

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!

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.
