Brown Stink Bug

Fascinating facts about the Brown Stink Bug

• Euschistus servus spans a transcontinental North American range, from British Columbia and Newfoundland-and-Labrador in the north down through California, Texas, Florida and into Mexico. This breadth means the bug encounters a huge variety of climates and agricultural systems, so its impact isn't limited to a single region. Recognizing its wide distribution alerts growers across the continent to stay vigilant, not just locally.
• The brown stink bug is extremely polyphagous, with host records that include about 70 species across 25 plant families. Such a broad diet lets it thrive wherever those plants grow, from wild weeds to cultivated fields. This feeding flexibility explains why the bug can quickly become a problem in diverse crops.
• Stink bugs, including brown stink bugs, have driven $279 million in soybean losses over the past six years. Researchers found that a dual-component lure (murgantiol <1%, methyl E,E,Z-2,4,6-decatrienoate <1%) consistently attracted more stink bugs than a single-component lure. Deploying pyramid traps with this lure can give growers an early warning system, turning costly surprises into manageable infestations.
• In the United States and Canada, the brown stink bug is the most economically important species of its genus, capable of damaging soybean, corn, cotton, alfalfa, sorghum, fruit, pecan, and tobacco.
