EMERALD ASH BORER FOUND IN THE TOWN OF SHERMAN IN FAIRFIELD COUNTY,
CONNECTICUT

New Haven, CT - The Connecticut Agricultural Experiment Station (CAES) announced today that the
emerald ash borer (EAB) (Agrilus planipennis) has been detected in another Connecticut county –
Fairfield – in the town of Sherman, CT on July 19, 2013. This invasive insect has now been found in two
Connecticut counties and twelve towns. The identification of EAB has been confirmed by the federal
regulatory officials in the USDA Animal and Plant Health Inspection Service, Plant Protection and
Quarantine (USDA-APHIS-PPQ). This new county detection, like that of the initial New Haven County
detection in 2012, was made through the Experiment Station’s Cerceris wasp biosurveillance program.
In Connecticut, a quarantine has previously been established that regulates the movement of ash logs, ash
materials, ash nursery stock, and hardwood firewood from within New Haven County to any area outside
of that county. The New Haven County quarantine mirrors a federal quarantine also imposed on New
Haven County. This Fairfield County detection will result in the expansion of the state and federal
quarantines in Connecticut.

The emerald ash borer is responsible for the death and decline of tens of millions of ash trees and has been
detected in 20 states from Kansas and Michigan to New Hampshire and south to North Carolina. Ash
makes up about 4% to 15% of Connecticut’s forests and is a common urban tree.
In Connecticut, the insects were previously confirmed in Prospect, Naugatuck, Bethany, Beacon Falls,
Waterbury, Cheshire, Oxford, Middlebury, Hamden, North Branford, and Southbury, all in New Haven
County, as part of surveys conducted by CAES, the Department of Energy and Environmental Protection
(DEEP), the U.S. Forest Service, and the University of Connecticut Cooperative Extension via an
agreement with USDA APHIS PPQ in joint efforts to detect the presence of EAB in the state or determine
the extent of the current New Haven County infestation. The Hamden detection was initially reported by
a homeowner. EAB has also been identified in Dutchess County, New York, Berkshire County,
Massachusetts and Merrimack County, New Hampshire.

A single specimen of EAB was recovered in Sherman from the ground-nesting, native wasp (Cerceris
fumipennis), which hunts beetles in the family Buprestidae, including the emerald ash borer. The wasp is
an efficient and effective “biosurveillance” survey tool and does not sting people or pets. In addition, 307
purple prism detection traps have been set across the state, excluding New Haven County, by the
University of Connecticut Cooperative Extension System. The EAB surveillance program is supported by
the USDA-APHIS-PPQ.

“This latest detection and those in an expanding area of New Haven County show how invasive this insect
can be - putting more of our ash trees at risk.” said State Entomologist Kirby C. Stafford III. “Not moving
firewood or ash is the best way to help slow the spread of EAB.”

“Now that EAB has been detected in another Connecticut county, it is more important than ever to curb its
spread and the most effective way to do that is preventing the movement of wood products out of affected
areas,” said DEEP Commissioner Daniel C. Esty. “We will continue to work closely with the Connecticut
Agricultural Experiment Station, the Department of Transportation, and other state and local agencies to
put effective strategies in place to limit the spread of EAB and minimize the impact this invasive beetle
has on Connecticut’s ash trees.”

In addition to the established quarantine, regulations are in effect regulating the movement of firewood
from out-of-state into Connecticut or within Connecticut, including the requirement of a permit to bring
out-of-state firewood into Connecticut. These regulations were put in place to ensure that EAB and other
invasive insects are not carried into Connecticut, or spread throughout New England, through the
movement of firewood.

Detailed information about the quarantine, including its expansion, and the firewood regulations can be
found at www.ct.gov/deep/eab or www.ct.gov/caes .

The emerald ash borer is a regulated plant pest under federal (7 CFR 301.53) and state (CT Gen. Statute
Sec. 22-84-5d, e, and f) regulations. For more information about the EAB, please visit the following
website: www.emeraldashborer.info. A fact sheet providing guidelines on the treatment of ash trees to
protect them from EAB is also available at www.ct.gov/caes.

The Wasps Are Out!

The Cerceris wasps are beginning to emerge at St. Anthony's Cemetery! We hope to begin monitoring these wasps during the first week of July, after the remainder of the individuals emerge.

One of the first wasp burrows of the year

Cerceris wasps are a native genus of stingless insects that hunt for beetles from the Buprestidae family.  After finding and stinging a beetle, these wasps bring the beetle back to their burrows.  The invasive emerald ash borer is one of the wasp's prey species, so groups across North America have found it helpful to monitor Cerceris colonies in order to detect the presence of this pest.  When a wasp returns to its burrow with its prey, we net it and identify it.  This way, we can determine if the wasps are catching any emerald ash borers in the area.

As part of a statewide effort to detect the emerald ash borer, White Memorial is monitoring the Cerceris colonies at St. Anthony's Cemetery, Wamogo High School, the Morris Town Beach, and Litchfield High School.

Claire Rutledge of the Connecticut Agricultural Experiment Station is hosting a training session for volunteers who would like to help monitor the wasp colonies.  The session is scheduled for 11 AM on Tuesday, July 2 in the Ceder Room.

Emerald Ash Borer Found in Prospect and Naugatuck, Connecticut

New Haven, CT – The Connecticut Agricultural Experiment Station (CAES) and the Department of Energy and Environmental Protection (DEEP) today announced that the emerald ash borer (Agrilus planipennis) was detected in Prospect, CT on July 16, 2012 by staff members at CAES. The identification has been confirmed by federal regulatory officials in the USDA Animal and Plant Health Inspection Service, Plant Protection and Quarantine (USDA APHIS-PPQ). This is the first record of this pest in Connecticut, which is added to 15 other states where infestations have been detected. A new probable site of infestation is located in the Naugatuck State Forest. The beetle identification is unconfirmed. The emerald ash borer is responsible for the death and decline of tens of millions of ash trees from the mid-west to New York State and south to Tennessee. Ash makes up about 4% to 15% of Connecticut’s forests and is a common urban tree.  

“The detection of the emerald ash borer (EAB) in Prospect and probably in Naugatuck reaffirms that statewide surveys for this pest were necessary,” said Louis A. Magnarelli, director of CAES. “We expected to find the beetle in areas of Connecticut across from infestations in Dutchess County, New York; however, the EAB has great flight potential and can travel in infested wood moved by people. This pest attacks all species of ash trees. Our immediate goals are to determine how extensive the Connecticut infestation is, notify residents in the Prospect and Naugatuck area, and implement strategies to slow the spread of the insect.”  


The insect specimens were recovered in Prospect from a ground-nesting, native wasp (Cerceris
fumipennis), which hunts beetles in the family Buprestidae, including the emerald ash borer. The
developing wasp larvae feed on the beetles provided by the adult wasp. The wasp provides a highly
efficient and effective “bio-surveillance” survey tool and does not sting people or pets. This work was supported by the US Forest Service. In addition, 541 purple prism detection traps, containing a special chemical lure, have been set across the state in all eight counties by The University of Connecticut Cooperative Extension System via an agreement with the USDA APHIS PPQ. Three additional EAB have been captured in a trap located in Prospect, while other beetles were captured in a trap in Naugatuck.  

“This is a disturbing discovery and one that has the potential for great environmental harm in the state,” said DEEP Commissioner Daniel C. Esty. “Connecticut has more than 22 million ash trees. The presence of EAB here could have a devastating effect on the beauty of our forests, state and local parks and neighborhoods, as well as the state’s wood product industries. Now that EAB has been detected here, it is more important than ever to limit its spread. It is imperative that residents and visitors throughout the state not move firewood. The movement of firewood that contains the presence of EAB is the quickest way to rapidly spread the insect. We will continue to work closely with the Connecticut Agricultural Experiment Station and other state and local agencies to do everything in our power to minimize the presence of EAB in Connecticut.”  

The EAB is a small and destructive beetle, metallic green in color, and approximately 1/2 inch long and 1/8 inch wide. Adults emerge from the bark of infested trees leaving a small “D”-shaped exit hole roughly 1/8 inch in diameter. This insect is native to Asia and was first discovered in the Detroit, MI and Windsor, Ontario regions of North America in 2002. It has since spread through the movement of firewood, solid-wood packing materials, infested ash trees, and by natural flight dispersal.  

It is unknown how the EAB entered Prospect or Naugatuck. Movement of infested firewood is a high risk activity that can spread the beetle over long distances. Prior to the pest’s discovery in Prospect, the closest known infestation to Connecticut is in eastern New York near the Hudson River.  

The emerald ash borer is a regulated plant pest under federal (7 CFR 301.53) and state (CT Gen. Statute Sec. 22-84-5d, e, and f) regulations. For more information about the EAB, please visit the following website: www.emeraldashborer.info.  

There will be a press conference at 1:15 PM at the Prospect Town Hall, 36 Center Street.
Representatives of CAES will be attending the press conference. Materials will be on display. Officials of USDA APHIS-PPQ, DEEP, and the CT Department of Agriculture are expected to be present as well.

Cerceris Wasp Bio-Surveillance of EAB -- 2012 Season Update

We collected our 50th beetle at Morris Town Beach today!  We have met our seasonal goal for each of our 4 colonies.  If you want to continue to collect beetles, please do so when it is a good time for you.  Every beetle that we collect tells a little something about the big picture of the EAB invasion!  The wasps will be active until late-July, at least.  Please keep in mind that Erin will be transporting the beetles to Claire in New Haven on August 1.  Therefore, if you have beetles in your possession, please get them (& datasheets) to us ASAP so they don’t miss the bus.

 Another successful season and no Emerald Ash Borer!

Cerceris Wasp Bio-Surveillance for Emerald Ash Borer -- 2012 Season Update

Although catching Cerceris Wasps can be challenging,
finding a Buprestid Beetle in the net is a great reward! 

We need your help!  The more people we have at each of the Cerceris colonies, the more beetles we catch!  That’s the secret to our success, so far.  Our goal is to collect 50 beetles at each colony so that we can assess the diversity of species now.  When Emerald Ash Borer colonizes the property, not only will we lose the ash trees but we will also see changes in the beetle population, too!  More importantly though, this project is really fun!  We need your help but don’t miss out on the fun.  


We finished Litchfield P.S. Plumb Hill Ball Field today with a total of 50 beetles, exactly!  On Tuesday there were 4 of us and we caught 25 beetles in two hours.  We finished this site in just a few days because we collected 50% of the goal in one day!


St. Anthony’s cemetery has 38 beetles so far, which means one more day’s worth of work will finish it off.  We’ve had one person at this colony by themselves for 3 days.  Those individuals caught 10 – 13 beetles each day.  We've almost finished with this colony!  Can you help us finish this colony tomorrow?  

Wamogo’s colony just woke up around Monday, but we have 13 beetles collected so far.  Three people caught 13 beetles in one day!  The pitcher’s mound is the place to be at Wamogo with over 20 nests.  Then there are the other nests in the rest of the diamond!  This site could be finished quickly with just a little bit of your help!

Morris Town Beach also woke up on Monday but we have not made it to that location yet, therefore no beetles have been collected at that site.  This colony is closest to some of our best ash stands on the property; therefore it is vital that this site not get put to the last colony for the season.  We can’t miss the big push.  We need you here!  

Please be part of this project.  As you can see if you want to part of the fun, you will need to be part of it before we finish the season without you.  

Contact me to let me know when and where you want to catch wasps and collect beetles.

Cerceris Wasp BioSurveillance for EAB Workshop

June 28, 2012

11:00 a.m. - 1:30 p.m.

A. B. Ceder Classroom

Emerald Ash Borer continues to march closer to our area.  This year EAB was documented for the first time east of the Hudson River!  Several methods are utilized to detect EAB's spread.  One method uses the native Smokey-Winged Beetle Bandit (Cerceris fumipennis) wasp.  These wasps don't sting humans and are fun to catch!  Claire Rutledge (CT Ag. Exp. Station) will facilitate our training and show you the importance of the project.  This workshop starts with introductory lecture indoors and is then followed by practicing the field techniques outdoors.  Please dress for the weather and bring water.  If you are interested in participating in this workshop please contact James Fischer, WMCC Research Director

Cerceris wasps have finished gathering Buprestid beetles for the season.  We collected a total of 73 Buprestid beetles this season from 4 colonies.  We collected 30 beetles from Morris Town Beach ball field, 26 at Wamogo Region #6 High School baseball field, 13 at St. Anthony’s Cemetery in Litchfield, and 4 at the Litchfield Public Schools Plumb Hill ball field colonies.  We observed approximately 40 nests at Morris Beach, 40 nests at Wamogo, 17 nests at St. Anthony’s, and 14 nests at Plumb Hill.  It was a very successful season this because we established our procedures and created a solid baseline of Buprestid beetles species before the Emerald Ash Borer colonizes the state.  This project was supported by several volunteers this year including Madeline Bove, Amanda Downey, Frank Errico, Ryan Gannon, Nicki Hall, Marcus Johansson, Nicole Morin, John (Jack) Nelson, Carol Perrault, Henry Perrault, Olivia Scott, and Rebecca Solnit.  Claire Rutledge, Connecticut Agriculture Experiment Station Entomologist, is our state sponsor/facilitator. 

Thank you Claire for extending your leadership with this project, it’s a worthwhile program.

We identified 4 colonies of Cerceris Wasps in close proximity to the property.  The wasp watchers have been  steadily collecting beetles (42 from all of the colonies) that the wasps have been bringing back to their nests.  The wasps become active every sunny day around 11:00 a.m. EST with their orientation flights around the nest entrance.  Very soon after leaving they start bring back beetles to their nests, where the wasp watchers are waiting to catch and release the wasp unharmed but leaving a beetle in the bottom of the insect net.  The beetles are sent to our state's coordinator for this project Claire Rutledge at the Connecticut Agricultural Experiment Station.

Cerceris Wasp Field Trip Results

White Memorial staff, interns, and volunteers

gathered around a Cerceris Wasp colony at

St. Anthony's Cemetery on White's Woods Rd.

On Thursday, 7/7/2011, 9 White Memorial staff, interns, and volunteers took a field trip to St. Anthony's Cemetery on White's Woods Rd. in Litchfield to learn more about Cerceris Wasps from Claire Rutledge of the CT. Agricultural Experiment Station. James Fischer had previously located a small colony of these wasps here, so it provided an ideal setting to learn more about them. We found 13 holes in the hard-packed soil along a little-used dirt driveway. These wasps seem to prefer hard soil over soft. The photo below shows a wasp peeking out of its hole.

The photo below shows a typical Cerceris wasp

Claire supplied us with nets, collecting bags, hole collars, and other equipment that we can use to steal Buprestid beetles from the wasps when they return to their burrows with these prey items. The primary goal is to monitor for the non-native, invasive, and highly destructive Emerald Ash Borer beetle, which is in the Buprestid group, and which is readily captured by these wasps in the Great Lakes states. They haven't been found yet in Connecticut, but this is a relatively easy way to monitor for their presence.

Emerald Ash Borer is another invasive species threatening Connecticut's biological diversity.  This insect feeds on and kills ash trees.  One method used to detect Emerald Ash Borer as part of Connecticut's early warning system is to use Cerceris Wasps.  Cerceris Wasps are a native species that predate buprestid beetles, which includes the Emerald Ash Borer.  The efficacy of this surveillance method for EAB is better than many of the other methods that are being employed.  Yet, the best survey scenario is when all of the surveillance methods are incorporated collectively.  We need your help!  We need volunteers to observe Cerceris Wasp colonies and collect the prey that they collect.  These prey insects will be identified by entomologists to see if Emerald Ash Borers have invaded the state/region.  Claire Rutledge, CT Agriculture Experiment Station Entomologist, will facilitate a workshop on Tuesday June 28 at 1:30 p.m. in the A. B. Ceder Classroom to teach us how to perform this work.  This will be Part 1 of that 2 part workshop.  The second session will include the field methods and will be scheduled at the first session.  If you have any questions please contact James Fischer. james(at)whitememorialcc.org or 860-567-0857
