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).

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.
