Understanding life cycle assessments with Dr. Rosentrater

Soybean Pest Podcast
Season:

Episode:

Description: 

Matt and Erin have a special guest on this podcast to help understand life cycle assessments. Dr. Kurt Rosentrater is an engineer and associate professor at Iowa State. Kurt explained the basics of conducting a life cycle assessment, including assumptions and resulting complications that come with this tool. They focused on a recent example looking at environmental impacts in four major crops. Here is the link to the paper so you can follow along with figures: http://www.ingentaconnect.com/content/iop/erl/2015/00000010/00000009/art094016. The assessment showed freshwater ecotoxicity impact in soybean increased 3-fold from 2002 to 2012. The authors claimed the insecticides used to control soybean aphid was an important factor. Corn, cotton and wheat did not have a significant increase of impact over the study duration.

Today, Matt talks about a "farminar" with PFI (Practical Farmers of Iowa) he recently recorded. It was about neonic seed treatments in soybean. Watch the archived version here: http://practicalfarmers.org/farmer-knowledge/farminar-archive/neonicotinoid-seed-treatments-are-they-necessary/. Then Erin mentioned Pollinator Fest this summer is happening on Saturday, June 25 in Ames. But the majority of the time was spent interviewing an incoming post-doc, Matt Kaiser. He will start in Matt's lab this summer and work on a new parasitoid wasp that attacks soybean aphid. He reviews wasp biology and talks about how this new tool can help suppress soybean aphids in Iowa.

In this episode, Matt and Erin talk about upcoming events, pest activity updates and research projects. Erin is organizing a Corn Insects Workshop on July 29. Learn more and register here: http://www.aep.iastate.edu/feel/insect.html. There is a 50-person cap, so register now if you want a space! Erin had several reports of pea aphid in alfalfa, but most farmers decided to cut instead of spray. Learn how to identify aphids in alfalfa here: http://crops.extension.iastate.edu/cropnews/2016/05/aphids-showing-alfalfa. Erin also saw a few aphid mummies in clover and they both experienced honeydew dripping from a tree on campus this week. Matt talked a bit about planting conditions for his wasp and bee projects, noting compaction and crusting in some commercial soybean fields.

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.
