TREES Inc. to host Emerald Ash Borer summit

Special to the Tribune-Star

TERRE HAUTE — Area experts on an invasive, exotic beetle that has destroyed local ash trees will explain the latest treatment options at the third annual Emerald Ash Borer summit.

TREES Inc. will host the summit from 12:10 p.m. to 1 p.m. on Feb. 20 at the Vigo County Public Library at one of its brown bag programs.

Stephanie Krull from Indiana State University’s grounds and maintenance department and Adam Witte from Purdue University will be the speakers.

Krull, ISU’s landscape and grounds manager, will discuss ISU’s partnership with Purdue University’s entomology department to study the effects of EAB on ISU’s property. Krull will share a comparison of treatment methods both on treated trees and on untreated trees both adjacent and not adjacent to treated trees.    

Witte’s experience with EAB began when he worked in the summers in Fort Wayne for his father’s landscape company. He began treating for EAB in 2008.

He received bacherlor’s and master’s degrees in entomology at Purdue. His master’s work was focused on ornamental plant pests. He is currently the forest pest outreach coordinator at Purdue University.

The Emerald Ash Borer causes significant damage to all ash trees, and if left untreated, eventually kills the tree. Larvae feed on the inner bark of ash trees, disrupting the trees’ ability to transport water and nutrients.

It is suspected the Emerald Ash Borer arrived in the United States on solid wood packing material carried in cargo ships or airplanes originating in Asia.
