We share reports of aphid outbreaks in soybeans in MN. Numbers are up in Iowa. Also, have you noticed big, metallic green beetles? Japanese beetles are out in Iowa.
In this episode, Matt and Erin transition from providing weekly field crop pest updates to other topics of interest. They discuss the new assessment form provided by the Xerces Society to help farmers understand the value of beneficial insect conservation. Find the form here: http://www.xerces.org/wp-content/uploads/2015/07/HAG_BeneficialInsects_June2015_web.pdf
As the tagline for the new movie, Popstar, says: Never Stop Never Stopping!
Today, Erin gives a short note to announce the new podcasting widget. It will be located on their Soybean Entomology Lab website, where other resources are available. You can still subscribe to the podcast via iTunes, Stitcher or Pocket Casts. Thanks for listening!
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).
