Entomology
The Department of Entomology works through two colleges-the College of Agriculture and Natural Resources and the College of Natural Science. This two-college arrangement enables students to integrate the agriculture/natural resources and biological/physical sciences in an optimally beneficial way
The Entomology department has a long history of excellence in research, extension, and graduate education and we continue to focus on these areas for the issues that confront us today and for the future.
Emerald ash borer
Emerald ash borer (EAB), Agrilus planipennis Fairmaire, is an exotic beetle that was discovered in southeastern Michigan near Detroit in the summer of 2002. The adult beetles nibble on ash foliage but cause little damage. The larvae (the immature stage) feed on the inner bark of ash trees, disrupting the tree's ability to transport water and nutrients. Emerald ash borer probably arrived in the United States on solid wood packing material carried in cargo ships or airplanes originating in its native Asia. Emerald ash borer is also established in Windsor, Ontario, was found in Ohio in 2003 and northern Indiana in 2004. Since its discovery, EAB has:
• Killed at least 8 million to 10 million ash trees in Michigan, Ohio and Indiana. Most of the devastation is in southeastern Michigan.
• Caused regulatory agencies to enforce quarantines ( Ohio, Indiana, Michigan) and fines to prevent potentially infested ash trees, logs or firewood from moving out of areas where EAB occurs.
• Cost municipalities, property owners, nursery operators and forest products industries tens of millions of dollars.

New Invasive Insect Confirmed in Michigan
LANSING - The Michigan departments of Agriculture (MDA) and Natural Resources (DNR), along with the U.S. Department of Agriculture (USDA), today announced the confirmation of Sirex Woodwasp in Macomb County. A single specimen was collected from a trap on July 6 and later identified by the USDA. Sirex Woodwasp is a wood-boring insect native to Europe, western Asia, and northern Africa and is a potentially serious pest of commercially produced pine trees. It was first detected in North America in Oswego, N.Y. in 2004, and has since been found throughout central New York, northern Pennsylvania, and southern Ontario.
The larvae of this exotic pest are responsible for damaging the tree. It severs the trees' conductive tissues, interrupting the transport of water and nutrients. Adult females lay their eggs in two- and three-needled pine trees, including: Austrian, jack, red, and Scotch pines.
"At this point, we don't know whether this is part of an established Michigan infestation," said MDA Director Mitch Irwin. "We don't anticipate this pest to have a major economic impact on the state's nursery, landscape and Christmas tree industries. We will, however, vigorously monitor this exotic pest and its potential to impact our forest systems."
The trap is one of more than 250 trapping locations established throughout Michigan through a cooperative effort that includes the USDA, MDA, DNR, Michigan Technological University and Michigan State University. This work is part of an international effort to delimit the extent of the infestation in North America.
"Since the Sirex find in New York we have been monitoring Michigan's pine resource," said DNR Director Rebecca A. Humphries. "The network of traps and trap trees established across Michigan will provide excellent data. This information will be used by the workgroup to assess and develop a pro-active response."
Sirex Woodwasp is not expected to significantly impact healthy landscape pine trees in the state. Its impact on vigorous, well managed pine plantations in Michigan, while not yet fully defined, is likewise not anticipated to be severe.
