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.
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!
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.
