Our extension program is led by Dr. Erin Hodgson, and Dr. O’Neal and many lab members also participate in programs throughout the year. We are focused on delivering research-based information to a variety of clientele. Our group serves farmers, crop consultants, agricultural professionals and other university/extension personnel. Most of our programs are within the state of Iowa, but we travel throughout the Midwest to deliver content. Read more about Extension
Despite a slow start to planting, some insects are starting to respond to emerging soybeans.
In this episode Erin and Matt kick off the 13th season on the 13th of June with a brief discussion of the spiders on Stranger Things before getting into soybean pest activity. Erin reviews predictions about bean leaf beetle winter mortality and subsequent activity on spring emerging soybeans. Erin also reviews her groups work tracking several lepidopteran pests (that’s a bunch of moth species that feed as caterpillars on corn and soybeans). Matt notes that it’s not just soybeans that these hungry beetles are feeding on.

Erin and her technician Ashley Dean have developed a pest alert system. Visit this website for more details- https://pestalerts.extension.iastate.edu/.

Erin and Matt recap a week that saw several firsts for 2022.
Soybean aphids were first sighted, so too were thistle caterpillars, and Japanese beetles. We are obligated to encourage you to scout for these pests, as the season goes on. Thier first appearance is not a cause for alarm, just a reminder that these potential pests may cause trouble later in the season.

After summarizing 5 different pests (soybean aphids, Japanese beetles, Thistle caterpillars, gall midge, Armyworms), Matt introduces 2022's first Fun Insect Trivia question.

Here at the soybean pest podcast, we do not limit ourselves to our namesake. After Erin summarizes ongoing effortst to track insect pests of soybeans, we look to Iowa's other commodity, corn. She breaks down the progress of soybean aphids, Japanese beetles, thistle caterpillars and leaf hoppers (in the drought plagued corner of nortwest Iowa). We discuss corn rootworms, and old wives tale connecting rootworms to lighting beetles and a surprise attack of stink bugs to a corn field in southeastern Iowa.

After the pest talk, Erin shares a new insect identification challenge from University of Nebraska. See how well you do against Professor Doctor Erin, she scored a 97%. https://4h.unl.edu/online-insect-id-contest?fbclid=IwAR1uNzEBoqEgQx9QYcw...
Matt completes the pod with a Fun Insect Trivia question. What do the four insects have in common? Below are the scientific names that he tries to pronounce. If you look up the common names, you'll immediately learn the answer.
