Pest of the Month -- July
Emerald Ash Borer
|
The dark metallic green Emerald Ash Borer, discovered in 2002 in Michigan, is a devastating pest of ash trees. The adults are 1/2 inch long and 1/16 inch wide. Larvae have unusual triangular segments and create a unique S-shaped tunneling pattern under the bark. Adult emergence begins in mid to late May and peaks in early to mid June, although adults may still be present in August.
Look for these symptoms of Emerald ash borer infestation: trees dying from the top down, D-shaped exit holes, and/or dense sprouting of shoots arising from the trunk or roots. The ash borer can spread through movement of infested trees or in logs and firewood from infested areas. Take care not to bring ash trees, logs, or firewood from quarantined areas into Kentucky! --Source: Michigan Department of Agriculture |
