Guide to everything you need to know about soybean aphids

The second edition of the Soybean Aphid Field Guide is now available for growers in printed form or onlne. The revised guide offers new information about aphid-resistant soybeans.

The very latest information about soybean aphids is now available online and in a field guide from the Iowa Soybean Association (ISA). ISA and Iowa State University (ISU) have released a collaborative second edition of the Soybean Aphid Field Guide. The guide’s authors are ISU Extension entomologist Erin Hodgson and ISU research entomologist Matt O’Neal. 

“Every year we learn more about the biology of soybean aphids and new ways to prevent this pest from causing yield loss,” O’Neal says. “We have incorporated these discoveries and tools into the revised edition of the guide in an effort to return this soybean checkoff-funded research back to soybean farmers.”

One of the biggest additions to the toolbox of aphid management strategies is aphid-resistant soybeans. The guide includes a review of the research that led to aphid resistance becoming a common component of soybean genetics for many current and future commercial soybean varieties.

Printed copies of the Soybean Aphid Field Guide can be obtained by contacting the Iowa Soybean Association at 800/383-1423; they can also be ordered from the ISU Extension Online Store at by calling 515/294-5247. The guide can also be viewed online at
