• Cypress Bark Beetles

      Schalau, Jeff; Entomology (College of Agriculture and Life Sciences, University of Arizona (Tucson, AZ), 2003-06)
      Cypress bark beetles are native insects that often impact ornamental Arizona cypress and Leyland cypress trees. Healthy, vigorous cypress trees can usually withstand substantial beetle pressure. However, significant mortality of host tree species often occurs during periods of extended drought. Tree vigor can easily be maintained through deep, infrequent irrigation during drought periods.
