This is the first weekly report of the Michigan State University Extension brown marmorated stink bug (BMSB) monitoring network. More than 60 traps were set up last week near crops that would be favored by this pest including apples, stone fruits (peaches, plums, sweet and tart cherries), blueberries, grapes, strawberries and a variety of vegetable crops. Several urban locations where BSMB were reported last year are also being monitored.

Based on what is currently known about the biology of BMSB and its favored non-crop habitats, sites have been selected that are adjacent to riparian habitats, woodland, soybean fields, major transportation corridors or various combinations of these attributes. Counties being monitored in 2015 are Allegan, Antrim, Benzie, Berrien, Clare, Grand Traverse, Ingham, Ionia, Kent, Lapeer, Leelanau, Lenawee, Livingston, Macomb, Monroe, Oakland, Oceana, Ottawa and Van Buren.

Most of the traps in the network are the pyramid style with a large, clear container on top baited with a green two-component lure.
