Update on finding the brown marmorated stink bug

It’s worth noting the role of MSU Extension in confirming this pest has entered Michigan.

Recently, Michigan received the bad news that another invasive pest has arrived in our state, the brown marmorated stink bug (BMSB). This stink bug feeds on fruits, vegetables, corn, soybeans and much more. It is difficult to control with insecticides and is a smelly nuisance that clusters on and in homes when the weather turns cold.

Several agencies including the Michigan Department of Agriculture, USDA Animal and Plant Health Inspection Service (APHIS) and MSU Extension to name a few, are in place to be vigilant about identifying and mitigating the effects of any new pests that enter our borders.

An early press release stated that two Michigan State University (MSU) students collected the first specimens that were verified by USDA entomologists. We posted that press release at this website (read it). Later more information filtered into me and I think it is worth noting the role of MSU Extension in this process. The specimen in Berrien County was identified as one of concern by MSUE Educator Duke Elsner and he submitted it to the USDA for further verification. A resident in Eaton County brought the second specimen into his local Extension office to MSUE Educator George Silva who sent it to MSU Diagnostic Services. There, entomologist Howard Russell identified it as brown marmorated stink bug and forwarded it to APHIS for confirmation.

MSU entomology specialists are gathering information and writing research proposals to address the issues this new pest will create. Here is some information that is currently available:

  • A fact sheet from MSU field crop entomologist Chris DiFonzo and insect diagnostician Howard Russell.
  • An article by MSU fruit entomologists Anne Nielsen, Matt Grieshop and Larry Gut.
  • A fact sheet from the North Central Integrated Pest Management Center.

Here are additional resources and information collected by Chris DiFonzo and Howard Russell:
