New records of Agrilus planipennis in Canada and USA
In 2008, new records of Agrilus planipennis (Coleoptera: Bupestridae – EPPO A1 List) were made in Canada and the USA. In all cases, phytosanitary measures are taken to contain the pest and to eradicate it whenever possible.
- Canada
In Canada A. planipennis was first recorded in Ontario in 2002. So far, its presence was confined to the Essex County and the Municipality of Chatham-Kent; and to Lambton, Elgin, Middlesex and Norfolk Counties. In June 2008, the presence of A. planipennis was confirmed for the first time in the south of Québec, in the Montérégie region.
In Ontario, A. planipennis was also detected for the first time in the following cities:
-Brampton (July 2008, infested trees were located in the Dixie Road and Steeles Avenue area).
- Oakville (August 2008)
- Ottawa (August 2008)
- Vaughan (August 2008, infested trees were located in the Highway 7 and Weston Road area).
The pest status of Agrilus planipennis in Canada is officially declared as follows: Present (only in some areas of Ontario and one area of Quebec) and subject to official control.
- USA
In the USA, A. planipennis was first recorded in 2002 in Michigan, and later in the states of Illinois, Indiana, Maryland, Ohio, Pennsylvania, and Virginia. In 2008, its presence was confirmed for the first time in Missouri and Wisconsin. In July 2008, 7 specimens were caught in a trap placed in Wayne County, Missouri. In August 2008, one adult beetle and numerous larvae were collected from ash trees in a private wood lot in the city of Saukville, Ozaukee County, Wisconsin. In the immediate vicinity, 20 to 25 trees displayed signs of infestation by A. planipennis (D-shaped exit holes, galleries, dieback). In both states, delimiting surveys are being carried out to determine the distribution of the pest.
The pest status of Agrilus planipennis in the USA is officially declared as: Present in some parts of the United States, but is subject to official control to prevent further spread.
