Description: 

Today, Matt and Erin are in Cleveland, OH for the 2016 Annual North Central Branch Meeting of the ESA (Entomological Society of America). They have a conversation with special guest, David Gammel, Executive Director of ESA since 2011. They learn more about David's "origin story" and how he got connected with the ESA. He also shares some of the most exciting things happening with the organization, including new Policy Fellows, a fun blog, and the upcoming international meeting. The Policy Fellows program will support and develop scientists as visible and effective advocates for entomology and entomological research. The Entomology Today Blog helps translate insect-related news to a wide audience; recent articles include topics like a Zika symposium, emerald ash borer control, and tick-borne diseases. They also talk about our upcoming ICE (International Congress of Entomology) Meeting in Orlando this September. In addition to a lot of scientific content with over 6,000 expected participants, there will be informal chances to learn more about insects.

Drought and spider mites go together like PB & J

Show: 
Soybean Pest Podcast
Season: 
7
Episode: 
9
Description: 

Don't drought this episode was a good one. Matt shares an update on the Iowa drought and encourages people to use the U.S. Drought Monitor as a tool to measure landscape moisture levels. Matt and Erin transition and talk about pest activity around the state, starting with twospotted spider mite. Erin wrote a recent ICM News article that talks about scouting and managing this pest that favors hot and dry conditions. Spider mites can be first detected around field perimeters and then eventually infest the field interior. Discoloration, webbing and stunted plants are often the result of heavy spider mite feeding. Erin mentioned a new miticide, AgriMek, that has promise for suppressing mites in corn and soybean; find the label here. The conversation switched gears to talk about some corn silk clipping pests, like Japanese beetle and corn rootworm adults. Scouting to determine pest densities and potential interference with pollination is important. Learn more about Japanese beetle ID, scouting and management with an ICM News article

Description: 

Due to technical difficulty, this is a second take at the podcast today. Matt and Erin start by sharing highlights from the recent International Congress of Entomology (ICE) meeting in Orlando last week. Erin talks about pest resistance issues for corn rootworm and western bean cutworm. Matt summarizes some work on rapid resistance development in agro-ecology systems. Fall nuisance invaders were also briefly discussed, including minute pirate bugs, boxelder bugs and lady beetles. Matt got excited by a recent aphid find on ISU campus this week - aphids and parasitized aphids were on collected from buckthorn. They don't understand the implications for these finds yet, but it is certainly not a common find. Lastly, Matt and Erin are speaking at the upcoming ICM Conference in Ames. Registration details will be posted soon.

Description: 

Matt and Erin wrap up a few loose ends before the holiday week. First, Matt shares DowAgroSciences sulfoxaflor insecticide got a renewed registration. This insecticide targets fluid-feeding insects and was an option for soybean aphid before it was canceled in 2015. Now, sulfoxaflor can be used in a number of crops, but not for corn or soybean; cotton and sorghum have emergency labels in some U.S. states. Over the weekend, a soybean aphid Biotype-2 colony died due to a bad compressor in a growth chamber. Aphids don't tend to do well in temperatures over 100 degrees, and these ladies got cooked. Our labs host all four soybean aphid biotypes plus a few other aphid colonies. Colony management is really important and the maintenance is ongoing to keep plants and aphids healthy. Iowa State University features a 3MT (Three-minute thesis) oral competition this week. Three people featured insect-related presentations (a long video of all the speakers can be found here).

In Episode 2, Matt and Erin cover a range of topics. First, they summarize planting conditions for 2017 - most places in the state are too wet and and cold to plant. The weather also affects insect activity as well. Matt expands on a recent ICM News article by Erin regarding "green bridges." Both had students graduating this semester - congrats to Eric Clifton and Shelby Pritchard on all your hard work and efforts during your time at Iowa State! Finally, Matt updates us on the recent legislative activity to close the Leopold Center for Sustainable Agriculture.
