A new, pocket-sized identification card for stink bugs in the Midwest will make identification of these insects much handier. Iowa State University Extension has just released the new identification card from authors Laura Jesse, Erin Hodgson, Donald Lewis, Matt O’Neal and Adam Sisson. The card was made possible with funding from a 2011 North Central IPM Center mini-grant.
In 2011, the brown marmorated stink bug (BMSB) was confirmed in Iowa. These were dead specimens; no live BMSB have been confirmed this year. ISU entomologists are actively looking for this pest throughout the state because this invasive species has the potential to damage corn, soybean and many other plants. In addition, BMSB is a home invader similar to the multicolored Asian lady beetle.
BMSB nymphs and adults have unique body characters (Fig. 1), but are easily confused with other stink bugs and incidental insects. This new card will help you distinguish some of the most common look-alikes in Iowa. In addition, a previous ICM News article gives longer descriptions for stink bugs.
