Michigan brown marmorated stink bug report for July 17, 2014

Julianna Wilson<jkwilson@msu.edu>, and Larry Gut, Michigan State University Extension, Department of Entomology -

A statewide brown marmorated stink bug monitoring program in fruit and vegetable crops continues with more sites reporting, but still no detections to report.

This is the second weekly report of the Michigan State University Extension brown marmorated stink bug (BMSB) statewide monitoring program for 2014. We now have more than 60 sites being monitored with pyramid-style pheromone-baited traps for BMSB, the majority of which are at farms that grow a variety of fruit and vegetable crops including apples, tart cherries, sweet cherries, peaches, blueberries, raspberries, tomatoes, peppers, and sweet corn. Sites have been selected that are near riparian areas or are along major transportation corridors in the following counties: Monroe, Lenawee, Oakland, Macomb, Livingston, Ingham, Lapeer, Saginaw and Bay on the east side of the state, and Antrim, Grand Traverse, Leelanau, Benzie, Oceana, Newaygo, Kent, Ionia, Ottawa, Allegan, Van Buren and Berrien on the west side of the state.

A couple of native stink bug species were caught in traps set out in apple and tart cherry orchards in a few sites this week in Monroe, but still no BMSB. However, there were two reports of BMSB caught in sweep net samples from field crop sites this week, one in Monroe County near Erie, Michigan and the other in Ingham County near Holt, Michigan.

To learn more about how to monitor for the brown marmorated stink bug, distinguish it from other similar-looking stink bugs, what crops it favors, and management strategies should populations reach the threshold where management is necessary, visit MSU’s Brown Marmorated Stink Bug website.

The weekly BMSB statewide monitoring report has been funded through Project GREEEN and Michigan State University Extension. This output is generated through a network of MSU Extension field staff and campus specialists. We would like to acknowledge the following team members and thank them for their weekly scouting efforts and input into this report: Peter McGhee, Michael Haas, Bob Tritten, Mark Longstroth, Brad Baughman, Carlos Garcia, Amy Irish-Brown, Lina Rodriguez Salamanca, Ben Philips, Mark Whalon, Hal Hudson, Karen Powers, and Nikki Rothwell.

Dr. Gut's work is funded in part by MSU's AgBioResearch.
