Stink Bugs Hitting Corn and Soybeans

If you're raising crops anywhere south of southern New York, be on the lookout for a bug-ugly insect – the brown marmorated stink bug. The adult (pictured here) can be devastating to many crops, and is hardest to control once it reaches this stage.

All spring, this publication and website have been urging farmers to scout for BMSB, and have a control plan in place. As the insects mature, they become harder to control.

STINKING SAP-SUCKERS: Scouting reports in southern Pennsylvania and central Maryland indicate BMSB adult populations are exploding.

On Friday, Penn State Extension Entomologist John Tooker reported that above-threshold levels of the insect are being found in corn and soybeans in numerous places in the Mid-Atlantic. University of Maryland entomologists also report that stink bug populations have jumped five to 10 fold in the past week at their monitoring stations.

Plant Management Network has launched a new webcast in its Focus on Soybean webcast resource. The webcast is titled "Brown Marmorated Stink Bug: A Confirmed Pest of Soybean". It's produced by Ames Herbert, professor of Entomology at Virginia Polytechnic University. The webcast is open access through August 31, 2011.

In the latest webcast of Focus on Soybean, a nonprofit online publication of the Plant Management Network, Herbert addresses:

Preliminary results of in-field distribution studies and field cage studies to measure its impact on soybeans

Preliminary management recommendations

Results of insecticide effectiveness studies

Images of BMSB injury to soybean pods, seed and the "stay-green" condition in fields.

The presentation was co-authored by Tom Kuhar, entomologist at Virginia Polytechnic University; Galen Dively, professor emeritus at the University of Maryland; and Joanne Whalen, Extension IPM specialist at University of Delaware. View it at:
