Description: 

Matt's a bit under the weather in this episode, but that won't stop his awesome commentary (see connection to Michael Jordan here)! Today, Matt and Erin talk about a new research development with soybean aphid. The entire genome was recently sequenced; see journal paper here). This is only the fourth aphid genome to be sequenced so far. Colleagues, Drs. Brad Coates and Andy Michael, helped generate data for this journal article. Matt explains the reasoning for sequencing the genome of pest species like soybean aphid. Once we have a better understanding of the genetic makeup of a pest, we can try to disrupt it and make them less successful. Then, Erin shares some recent questions coming to her from around Iowa - particularly if snow cover can help insects survive the winter.

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: 

Matt and Erin took May off from podcasting, but had a lot to talk about in the third episode of season 8. The cool, wet spring resulted in delayed planting for some; however, many of their research plots went in the ground this week. There have been a number of black cutworm and true armyworm reports throughout Iowa the last two weeks. Treatment decisions are based on plant growth stage, pest density and injury. Read more about their biology and management in ICM News articles:

Scouting for pests in cover crops

Erin also reported common stalk borer is moving to corn and soybean, particularly in the southern counties. Fields with stalk borer injury should scout now. Also, some fields are experiencing slugs - injury is most noticeable in fields with high residue. Finally, Matt and Erin got a USDA Challenge Grant and are looking for an extension program specialist that can work with farmers, beekeepers and conservationists. Find the job description here

Don't freak out (about a few aphids)

Season:

Episode:

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: 

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: 

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

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!
