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!
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!
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.
This Soybean Pest Podcast episode is packed with good stuff! Matt starts off by sharing some positive data from USDA-NASS from Iowa. A recent report showed 45,000 honey bee colonies in Iowa, a 275% increase from 2017. Also, the number of in-season losses is down from last year. Erin talks about a new soybean pest that is showing up in western Iowa. The soybean gall midge can be a devastating stem-boring pest. She summarizes her observations in a recent ICM News article. Erin also notes aphid activity in increasing throughout northern Iowa - in corn and soybean. It's a good time to scout fields to check for aphids. Also, there is a newly-revised field guide for soybean aphid. Find the pdf and hardcopy versions at the Extension Store. Lastly, PFI is hosting a field day on September 6 near Marble Rock. Erin will share some information about host plant resistance for soybean aphid. Click here for more details.
It's been a few weeks, but Matt and Erin have a new episode out today! Erin starts off by providing a statewide update on soybean pest populations in August. Good news is that most fields had low pest pressure in 2018. Matt shares his impressions of a recent court ruling that will ban chlorpyrifos use in the U.S. The episode title is a play off of Warren Zevon's song, "Lawyers, Guns and Money" from 1978.
