Illinois To Drop Internal EAB Quarantine

Illinois To Drop Internal EAB Quarantine
2015 Survey Confirms Discovery of Emerald Ash Borer in 10 New Counties
SPRINGFIELD, IL- The state of Illinois will no longer restrict the movement of any cut, non-coniferous firewood within the state.  Illinois joins Missouri, Iowa, and Kentucky in the deregulation of Emerald Ash Borer (EAB).
The 2015 survey of traps detected EAB in 10 new counties in Illinois: Madison, Mercer, Jackson, Saline, Hamilton, Wayne, Clay, Jefferson, Washington, and Bond.  The addition of 10 new counties has brought the total count of confirmed counties to 60.

“The survey results this year support deregulation with nearly 60 percent of our counties confirmed positive for EAB,” said Plant and Pesticide Specialist Supervisor Scott Schirmer. “Over the past decade, the regulations and quarantines have served their purpose to slow the rate of spread and afford people time to manage for this pest.  However, there comes a time when the pest is too widespread to continue to regulate, and this is our time.”

Previously EAB presence was confirmed in 50 counties, but 61 of Illinois’ 102 counties were under a state quarantine, which was intended to prevent artificial or human assisted spread of the beetle.

“Even though the state of Illinois is lifting its in-state EAB quarantine, I urge all Illinoisans to remain vigilant against the man-assisted spread of not only this pest, but all invasive species,” said Acting Agriculture Director Warren Goetsch. “Illinois will remain part of a federal quarantine, meaning firewood or other ash related products cannot travel into a state that currently has regulations.  I urge people to consider the potential impacts of their actions, in general, before they move items like firewood.  We’ve witnessed the impacts EAB has had on our trees and budgets, and we want to prevent introduction and spread of other current and future invasive species.”

Since the first detection of the pest near Detroit, Michigan, in 2002, the beetle has killed more than 250 million ash trees.  The borer, known for its distinctive, metallic green wing color, is native to Asia.  Its larvae burrow into the bark of ash trees, causing the trees to starve and eventually die.  The tiny beetle often is difficult to detect, especially in newly-infested trees.  Signs of infestation include thinning and yellowing of leaves, D-shaped holes in the bark of the trunk or branches and basal shoots.  Each year  Illinois Department of Agriculture officials submit samples from various purple EAB traps throughout the state and send them to the USDA’s Animal and Plant Health Inspection Service (APHIS) to confirm the presence of EAB.

Anyone who suspects an ash tree has been infested should contact their county Extension office, their village forester or the Illinois Department of Agriculture at (815) 787-5476.

The Return of the Unwanted House Guest: Brown Marmorated Stink Bug

It’s the time of year when my email is flooded with reports of brown marmorated stink bugs. Yep, it’s a sure sign fall is upon us.

As the growing season winds down, the temperatures begin to cool, and the days get shorter, several insects take to hanging out on the sides of houses, garages, and window sills. While they may appear to be warming themselves in the sun, these wily little creatures are most likely scoping out a nice place to spend the winter months. The days of boxelder bugs and multicolored Asian ladybeetles are not over, but there is a new house guest in several parts of the state.

The brown marmorated stink bug has been present in Illinois for quite some time (feel free to use the search engine on the Hone, Yard, and Garden Newsletter site to read more about them), but in recent years they are becoming much more noticeable in several areas of the state and a real nuisance as well.

A great resource for homeowners is a publication from Cornell University. It's important to remember that it is geared towards homeowners in the east. While these management strategies are applicable in Illinois, the situations requiring treatment the landscape outside the home decrease the number of BMSB home invaders has been quite small.  The Unwelcome House Guest: Brown Marmorated Stink Bug--A Guide for Residents, Property Managers, and Pest Management Professionals

Currently, the known distribution of this insect in Illinois is limited. Homeowners are our primary source of information during the fall and spring. We are very interested in where these insects may be and continue to try to determine where they are in Illinois. 

If you believe you have BMSB, we would be very interested in looking at it. Suspect stink bugs may be sent to Kelly Estes, 1816 S. Oak St., Champaign, IL 61820. Please put stink bugs in a crush-proof container (pill bottle, check box, etc). You can also send a photo to kcook8@illinois.edu for preliminary screening if you wish.
