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.

Show notes

Today, Matt and Erin recap insect activity around Iowa. They also discuss implications of the dry weather for 2019.

Flash drought: some like it hot Jul 15, 2019

Show notes

After a break, Matt and Erin get together for episode 3 in 2019. Erin mentioned a flash drought is expected this week if high temperatures continue throughout Iowa. This could have implications for pest management - slowing down soybean aphid but perhaps accelerating twospotted spider mite. Erin also highlights current pest activity in field crops, including corn rootworm and Japanese beetle. But they spent some time talking about the newest pest in Iowa, soybean gall midge. So many unanswered questions, but it appears this will be an economic soybean pest. Matt comes back to an older podcast episode where they reviewed the cancellation of sulfoxaflor insecticide. It was recently registered (again) by the EPA and will be labeled in soybean. This insecticide offers an alternative mode of action for soybean aphid. Finally, Matt brings up a F.I.T. that is about isopods.
