Today, Erin is without her podcasting bestie, Matt. She summarizes the activity of a few field crop pests in Iowa. First, she mentions Japanese beetle is active in soybean now and will move to corn with the emergence of silks. There are also European corn borer egg masses and small larvae in non-Bt corn now. You can access a free publication to learn more about scouting and management of ECB. Erin also gives an update on thistle caterpillar and soybean aphid from the last episode - both pests are still active right now. Finally, she highlights potato leafhopper as an occasional pest of soybean and alfalfa. You can register for some upcoming demonstration events at FEEL for July 12 (Diagnostic Clinic) and July 13 (Management Clinic) right here.
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.
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.
Matt and Erin are back and starting Season 10! Erin kicks off the episode by summarizing current pest activity for 2019. It's been a cool, wet spring and delayed planting will influence early-season pest activity. Specific updates:
- Bean leaf beetle winter mortality was high.
- Seedcorn maggots are flying.
- Alfalfa weevils are active.
- Expected corn cutting dates from black cutworm are approaching.
- Soybean egg hatch is happening, most likely in northern Iowa, where most of the buckthorn is located.
Matt talked about a new F.I.T. (fun insect trivia), where he highlights the mosquito trapping network at ISU. Dr. Ryan Smith coordinated a mosquito and tick surveillance program to learn more about activity and disease incidence around the state every summer. Learn more about his historical data on his website.
Matt also had an opportunity to podcast with group of Iowa Youth who entered an NPR challenge. You can hear the episode where they talk about using insects for food here later this summer!
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.
Today, Matt and Erin recap insect activity around Iowa. They also discuss implications of the dry weather for 2019.
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. The first painted lady butterflies were also noted in Iowa over the weekend. Lastly, Matt poses the latest F.I.T. and talks about an invasive insect into North America.
Matt and Erin are back in the swing of podcasting after a long winter. But the pandemic means they can record the episode in their sweatpants! 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.
