DETROIT – Researchers are asking for your help to track a bug that can suck the juice out of plants, causing problems for local farmers.
Michigan State University wants to know if you’ve seen brown marmorated stink bugs in Northern Michigan.
The brown marmorated stink bug (BMSB) is a 0.5- by 0.625-inch shield-shaped insect that uses its piercing mouthparts to suck plant juices from fruits, seed pods and nuts on a wide variety of wild and cultivated plants. It was accidentally brought to North America from Asia sometime before 1996 and was first detected in Michigan in 2010.
Also known by its scientific name, Halyomorpha halys, BMSB adults and nymphs – the immature stages of the bug – feed on a number of important fruit, vegetable and ornamental crops. Where it has been established for some time, it is now a major pest for growers of susceptible crops.
At this time of year in their native habitat, BMSB would normally look for shelter in south facing rocky outcroppings and other protected areas. The perfect surrogate turns out to be south-facing walls of man-made structures. It is important to note that BMSB do not bite humans or their pets – they are strictly plant-feeding insects. Also, they do not nest or reproduce in homes, they are simply finding a place to take shelter from the cold and will atempt to find their way out again when spring returns.
If you or someone you know has seen this pest in or on the outside of your home or place of business, and you are outside of the area in which we now know it is well-established in Michigan (see map below), we want to hear from you! Go to the Midwest Invasive Species Information Network (MISIN) website or mobile app, register as a user (it’s free) and follow the instructions for submitting a report. A few minutes of your time can be incredibly helpful in officially cataloging and tracking this invasive pest.
As of September 2017, more than 8,000 reports have been submitted to MISIN from 61 counties, including four in the Upper Peninsula (U.P.), which is not shown—Houghton, Keweenaw, Marquette and Delta.
