Description: 

Matt and Erin wrap up a few loose ends before the holiday week. First, Matt shares DowAgroSciences sulfoxaflor insecticide got a renewed registration. This insecticide targets fluid-feeding insects and was an option for soybean aphid before it was canceled in 2015. Now, sulfoxaflor can be used in a number of crops, but not for corn or soybean; cotton and sorghum have emergency labels in some U.S. states. Over the weekend, a soybean aphid Biotype-2 colony died due to a bad compressor in a growth chamber. Aphids don't tend to do well in temperatures over 100 degrees, and these ladies got cooked. Our labs host all four soybean aphid biotypes plus a few other aphid colonies. Colony management is really important and the maintenance is ongoing to keep plants and aphids healthy. Iowa State University features a 3MT (Three-minute thesis) oral competition this week. Three people featured insect-related presentations (a long video of all the speakers can be found here).

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.

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: 

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: 

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.

Episode:

Description: 

This might be one of the best episodes yet, because Matt and Erin combine aphids with rock and roll. But first Erin gives a state update on pest activity that includes armyworms, leafhoppers, rootworm and bean leaf beetle. There haven't been any reports of soybean aphid in 2018 but immigration is expected soon. Matt is a friend of the FC Bugeaters and shares recent game activity from the midwest. The F.I.T. focused on an insect-themed game show tune and then they transition to a recently published article that hypothesizes AC/DC is noise pollution for insects.
