Investigators: Dr. Adam J. Varenhorst, Dr. Matthew E. O'Neal, Dr. Michael T. McCarville Read more about Determining the impact of induced susceptibility on avirulent soybean aphid populations on resistant soybean
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/.
