Erin and Matt talk about the growing community of insects found in soybean and cornfields.  Erin shares updates from her field staff, including observations of several species of lepidoptera that are still in caterpillar form. For more details visit,

She also gives an update on the frequency and growth stage of soybean gall midges.  For more information about the Soybean gall midge, visit

Finally, Erin mentions her rootworm trapping network. Details can be found here:

Matt shares a F.I.T. that was inspired by a 2019 interview of Saturday Night Live cast member Kate McKinnon,

Don't watch the clip until after you heard the clues, as Kate gives a way the name of the type of insect in her interview.  If you want a hint, names associated with this insect include, but are not limited to: biting, non-biting,  phantom, mountain, meniscus, and dung.



Erin and Matt are back. Erin talks about insect pests that are starting to show up in fields, including the soybean gall midge.  Matt shares a FIT inspired by a trip to a field of Iowa's newest crop.



Erin and Matt are back from a skipping a week. Erin shares a observations from around the state of a several different insect pest sightings, including japanese beetles, thistle caterpillars, and soybean aphids. This includes a discussion of Brian Lange's discovery of soybean aphids in north east Iowa. Erin also shares a first! Below is a link to the longer article about scouting for corn rootworm larvae.

Matt's been writing grants and a little out of it, but he took some time to challenge Erin and our listener with a Fun Insect Trivia. (Hint: its an insect).

Stay safe!





Erin and Matt talk about insects pests showing up in places other than soybeans, like alfalfa and the twin cities. Some are currently causing problems and others may be a problem in the future.

There are stalk borers on the move:

Matt gives a FIT with a bonus question and then goes on a historical tangent about the history of an ecological phenomenon described as "persistent and straightened-out movement effected by the animal’s own locomotory exertions or by its active embarkation on a vehicle.  It depends on some temporary inhibition of station-keeping responses, but promotes their eventual disinhibition and recurrence."

This FIT was inspired by the recent book, Tne Next Great Migration written by Sonia Shah.






In this episode, Matt and Erin quickly review current pest activity given slightly behind degree days in 2020.

Matt provides an update on brown marmorated stink bug, an invasive species on the rise in Iowa and Japanese beetle activity. Erin gives a short recap of recent pest conditions in soybean, noting wireworms. Matt wraps up the conversation with a newly-designed F.I.T. 


Matt and Erin took a 9-month break, but they promised to post more regular podcasts this year with Season 11. Erin provides a brief summary of statewide pest activity, including bean leaf beetle, seedcorn maggot, and alfalfa weevils.
