Emerald ash borer makes move into Texas

Texas A&M Forest Service has conducted surveys for emerald ash borer for several years. Large purple sticky traps are placed in trees to attract and entrap the beetles. Ever since the dreaded emerald ash borer (EAB) showed up in Arkansas and Louisiana, tree lovers have braced themselves for its inevitable arrival in Texas. Then, in May 2016, the insect was discovered in a single surveillance trap near Caddo Lake in Harrison County in east Texas. In 2017 all was quiet, with no officially reported sightings; but this summer the beetle has been found in possibly three new counties. What is EAB? The EAB is a small but powerful beetle pest–an enemy of ash trees. Adult beetles feed on ash leaves and deposit eggs on the bark of their ash hosts. The eggs hatch and the tiny larvae penetrate the bark to feed on water conducting tissues inside the tree. Within 2-3 years the tree loses the ability to conduct sap, and succumbs to the infestation. Within 10 years of initial invasion all untreated ash trees in an invaded area are expected to die. Read stories like this and more in your latest edition of The Ennis News.
