Winged aphids are still on the move in Iowa, although most fields still remain well below treatment levels. Neighboring states have notable aphids, so scouting should still continue.
Erin Hodgson talks about recent aphid populations and also some interesting defoliators in soybean.
Drs. Matt O'Neal and Erin Hodgson discuss current soybean aphid activity around Iowa and the region. Numbers are remaining low with some regions declining in density. They also discuss upcoming field tours (available at www.aep.iastate.edu).
Drs. O'Neal and Hodgson summarize reports from around the midwest and Iowa about the soybean aphid. Despite the lack of aphids in the fall, evidence so far is that they survived and are beginning to build up in the northern parts of Iowa. Numbers are still very low and do not require insecticides, but we compare 2011 to previous growing season.
We are getting close to the end of the season and soybean aphids have exceeded the threshold level in northern Iowa. Erin has come back from spraying research plots to share with us updates on timing, product choice and assessing the need for an insecticide during this aphid outbreak.
Also, Matt is going to be interviewed by WHO-TV this Friday. Look for a segment either Friday nite or during the weekend (23-25 Aug) about conserving bees.And finally, this episode is dedicated to Robert Pettis, our #1 fan.
On a special episode of the podcast, we are visited by Dr. Donald Lewis who asks; "Will the soybean aphid outbreak bring more lady beetles". This hard-hitting question is answered, to the best of their ability by Matt and Erin.
The lady beetle in question, is the multi-colored Asian lady beetle, Harmonia axyridis. This is a beneficial insect in soybean fields but a pest in our homes.
Today, Matt and Erin talk about potential soybean seedling pests, including bean leaf beetle, slugs and black cutworm. They also shared some details about Pollinator Fest, a special event to promote pollinators on June 20. Find out more here: http://www.reimangardens.com/event/pollinator-fest/.
In this episode, Matt and Erin podcast from Manhattan, KS to share highlights from the NCB-ESA meeting. We talk with Alice Vossbrinck, OSU graduate student, about her lady beetle study in the agricultural landscape.

“Apres moi, le deluge” is legendary quote from King Louis XV of France. Allegedly he said this with regard to what would happen to France after his death; After me, the flood. 15 years after a reign that saw the loss of wars, territory etc., the French Revolution broke out.
Today on the soybean aphid podcast, we turn this title around (after the rains, us) to discuss the consequences of the June rains that have dropped as much as 6 inches in a 72 hour period. Unlike the terrible decisions of King Louis, these rains can have a benefit to farms by limiting the impact of some pests, especially those in the soil. However, the rains have made it difficult to get into fields for herbicide applications.
We discuss the rain, its impact on pests, and the upcoming Pollinator Festival at Rieman Gardens in Ames this Saturday June, 20.
Also, help us come up with a new name for out podcast. Send your suggestions to Matt at oneal at iastate.edu and/or Erin at ewh at iastate.edu.
Matt is on vacation, but the show must go on! Erin talks about recent soybean pest activity in Iowa, including the beginning of soybean aphid sightings in northern counties. Also, some are seeing green cloverworm starting to defoliate plants. Both are at sub-economic levels but continue to scout to make timely treatment decisions in 2015.
