The Twolined Chestnut Borer — Nemesis Of Weakened Oaks

摘要

The Twolined Chestnut Borer is a native forest pest that is interesting to contemplate at this time because it becomes aggressive in Oaks weakened by drought and Gypsy moth defoliation. Drought was widespread across the state this year and Gypsy mothappears to be making a comeback in the Allegany area. It is also interesting to consider that it is in the same genus as the Emerald Ash Borer, illustrating the difference in behavior of a native pest compared to a very aggressive non-native. Rather thanreinvent the wheel, this issue's article was originally written in 1997 by Doug Allen and is every bit as accurate today as it was then.
