Michigan brown marmorated stink bug report for August 7, 2014

We caught one brown marmorated stink bug this week in a trap next to a peach orchard near Niles, Michigan and four in sweep netting of vegetation from sites next to field crops in Lenawee County.

This is the fifth weekly report of the Michigan State University Extension brown marmorated stink bug (BMSB) statewide monitoring program for 2014. Out of the more than 80 sites being monitored throughout the state, only one BMSB was captured in our traps. The trap was next to a peach orchard in Berrien County near Niles, Michigan. A few adult BMSB were captured at several sites in sweep netting of vegetation next to field crops in Lenawee County just north of the border with Ohio.

The monitoring network uses pyramid-style, pheromone-baited traps set up 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 known to favor BMSB near riparian areas or 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.

Although we continue to catch little to no BMSB, we know that BMSB are present in Michigan because of reports that have come mainly from homeowners in various parts of the state, and from sweep netting conducted in the edge of soybean fields. This monitoring network has been set up to provide early warning should BMSB start showing up in greater numbers in fruit and vegetable production areas as it has in mid-Atlantic states over the last decade.

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, Ben Werling, Mark Whalon, Karen Powers, and Nikki Rothwell.
