Drs. Matt O’Neal and Erin Hodgson created a podcast to promote IPM concepts, like identification, sampling, economic thresholds, and insecticide efficacy. They also talk about updates on invasive pests and regulatory news, and translate new research relative to insects in agriculture.

In the last episode of the year, Matt and Erin talk about midges in the news and interesting honey bee behavior. Here are links to some of the research Matt mentioned in his re-occurring F.I.T. segment:

Behavioral responses of honey bees to natural and synthetic xenobiotics in food. Liao et al. 2017

Bees prefer foods containing neonicotinoid pesticides. Kessler et al. 2015

NPR story about midges:“Scientists say miniature flies are a big worry for Antarctic island

It's mid-September and the tenth episode of Season 9! Erin provides a brief update on the newest soybean pest in Iowa - soybean gall midge. Activity has slowed drastically since the last episode and is coordinated with quickly maturing fields in western Iowa. Matt traveled to Brazil for a soybean congress and gave some updates on new invasive in this large soybean-growing country.

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.

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.

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.

In this podcasting episode, Matt and Erin talk about a disagreement in insect ID. The false Japanese beetle often emerges before the true Japanese beetles and people mistakenly confuse the two species. Erin recently wrote about the timing of adult emergence of JB in ICM News and how to tell the difference between the two species in an ICM Blog post. By the way, we think Erin was right on this one even though Matt was super confident! Matt gives a quick summary of hexapods used as college team mascots (Thanks to fellow podcaster, Jonathan Larson at UNL, for the list!). Pollinator Fest is next weekend at Reiman Gardens.

This podcasting episode provides a short recap of some early-season pests, like grubs, caterpillars and beetles. Matt is a fan of the Bug Eaters Nebraska soccer team, and lets everyone know their upcoming schedule.

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.

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.

In this second episode of Season 9, Matt and Erin bounce around a variety of topics. First, Matt provides an update on the neonicotinoid ban in Europe. Neonics have been temporarily banned in Europe for a few years because of risk to honey bees, bumble bees and wild bees. In February, more news came out that supports these risks to pollinators. A vote will happen soon that could possibly permanently restrict or ban neonic use in Europe. Then, Erin reminds us ticks are active in Iowa right now, so beware of these disease vectors if you are in areas with tall vegetation. Over 250 cases of Lyme disease and 17 cases of Rocky Mountain Spotted Fever were confirmed in Iowa in 2017. Send your ticks in for ID at the ISU Plant and Insect Diagnostic Clinic
