Abstract or Description:
Cypress bark beetles (Phloeosinus cristatus (LeConte)) are native insects that occur throughout Arizona. They are common in the Verde Valley, Prescott, Payson, and Kingman areas. Under natural conditions, most bark beetles act as natural thinning agents that remove dying, overcrowded, and unhealthy trees. Cypress bark beetles seldom cause mortality in healthy, vigorous trees. However, when host trees are drought stressed, bark beetle populations increase allowing the beetles to colonize seemingly healthy trees.
