Wanted: Location of Soapberry Borer Infestations in Texas

Regional Urban Forester, Oscar Mestas is asking that if "in your travels or at home and around your cities, towns, parks etc., keep an eye out for soapberry borer infestation." The Texas Forest Service has sent out the following email alert:

The Texas Forest Service is attempting to determine the current distribution of the soapberry borer in Texas. The soapberry borer, Agrilus prionurus, is an invasive wood-boring beetle recently introduced from Mexico that has been attacking and killing western soapberry trees in various counties of Texas. If you spot dead or dying western soapberry trees, please report the following information to Dr. Ron Billings at rbillings@tfs.tamu.edu. If possible, attach digital photos of the bark chips, larval galleries, D-shaped exit holes or other signs of attack, together with a close-up photo of the tree’s leaves, so we can confirm the identity of the pest. Please see the attached descriptions if you are uncertain how to identify western soapberry or the damage this flatheaded wood borer causes. Thanks for your cooperation.

Master Naturalist, Judy Ackerman reports: "There is a lovely stand of soapberry trees in the Tom May’s section of Franklin Mountains State Park. They are on the trail to Cottonwood Springs just across from the West Cottonwood Tin Mine."
