Description:
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.
Aphids in alfalfa: https://crops.extension.iastate.edu/cropnews/2020/06/aphids-observed-alfalfa-fields
There are stalk borers on the move: https://crops.extension.iastate.edu/cropnews/2020/06/start-scouting-stalk-borers-southern-iowa

Khapra beetle citing in MN:https://www.startribune.com/destructive-beetle-larvae-seized-at-international-falls-port-of-entry/570968452/
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.

For more details visit, https://crops.extension.iastate.edu/blog/erin-hodgson/caterpillars-noted...
She also gives an update on the frequency and growth stage of soybean gall midges. For more information about the Soybean gall midge, visit https://soybeangallmidge.org/
Finally, Erin mentions her rootworm trapping network. Details can be found here: https://crops.extension.iastate.edu/blog/ashley-dean-erin-hodgson/new-tr...
Matt shares a F.I.T. that was inspired by a 2019 interview of Saturday Night Live cast member Kate McKinnon, https://www.youtube.com/watch?v=63GC6z1RsQQ.
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.

Description:
Erin and Matt are back after a week off of podcasting to discuss a remarkable sitatution in Iowa. Soybean plants are developing faster than normal, 1-2 weeks ahead of schedule. Aphid populations are increasing. Are the plants going to out grow the aphids? So what should a farmer do? Erin and Matt discuss the pros and cons of a foliar insecticide application.
Erin discusses some insects attacking the other crop grown in Iowa (hint: its corn). Corn earworms are causing injury due to the second summer migration.
Its a drought in the wester half of Iowa and the duo discuss how that may or may not be the cause of more frequent observations of spider mites.
Finally, Matt has a short FIT-ish question for Erin that she gets right! That's two in a row.

Description:
It was a terrible, horrible, no good very bad week in central Iowa. Erin and I give a summary of the Derecho's impact. We give a brief shout-out to ISU Extension, and Meaghan Anderson's summary of the damage to corn (https://mailchi.mp/4d564a6886f2/aixk6z6qw1-5248549?e=89e709107e). Consider joining Meaghan's newsletter: https://iastate.us10.list-manage.com/subscribe?u=08f91c67b14ea5bf5a26ba3...
We also talk about the recent increase in soybean aphid populations and the occurence of sub-populations that are resistant to pyrethroids. This may result in soybean aphids remaining in fields that were sprayed with insecticide.
No fun insect trivia this week. It was enough just to clear the yard, fields, etc and get the power back on.
