Soybean Aphid Podcasts added to

Beginning in July, we have added podcasts to our site. A new podcast will be posted once a week during the growing season. In these podcasts will be updates on the status of the soybean aphid and insights into its management from research at ISU.

Please note the comment section added to each podcasts as well as the link 'Contact Us' in the upper right hand corner. Each of these are ways for you to ask Dr. Hodgson and O'Neal questions about soybean aphids and soybean pest management. We will address these questions and comments in future podcasts.

Second Soybean Aphid Podcast-Introducing Dr. Erin Hodgson.

In this edition, Dr. Erin Hodgson is introduced. She is the new assistant professor in the Department of Entomology at ISU with extension and research responsibilities focused on corn and soybean production. Dr. Hodgson's Ph.D. was spent studying the soybean aphid and how best to scout for it. She describes some of the work she is doing this summer, helping growers manage insect pests in soybean fields.

Soybean Aphid Resources

Specific topics regarding soybean aphid biology and management:

  • Review of soybean aphid management tactics
    In this reprint from the 2005 ICM conference is a review of research conducted at Iowa State University regarding different management tactics for soybean aphid, including herbicide-insecticide tank mixes, seed treatments and the current recommendation.
  • Speed Scouting for soybean aphid University of Minnesota entomologist are developing this streamlined sampling method that employs the 250 aphids/plant threshold.
  • Aphid estimator
    Use this spreadsheet to calculate potential aphid population growth 7 days into the future using a temperature-based model.
  • Soybean Aphid suction trap network
    Visit this site for weekly updates of winged soybean aphids caught in a network of suction traps deployed across the midwest. Winged aphids during the summer travel between and within soybean fields. In the fall (September to October), winged soybean aphids migrate back to buckthorn where they overwinter. Ongoing research is investigating whether these numbers are an indicator of successful soybean aphid overwinter and thus an indicator of the risk for outbreaks for the subsequent summer.
  • SAILS-Soybean Aphid IPM on a Landscape Scale. This multi-state, USDA-funded project is designed to improve and integrate management of soybean aphid into Midwest cropping systems (soybeans, dry beans, snap beans, and others). Visit this site for quarterly research updates on soybean aphid management tactics including scouting, tank-mixes, and biological control
