Greater Peach Tree Borer (Synanthedon exitiosa)

Identification
  • A pest of most stone fruit trees.
  • Also called crown borer, the larvae of the clearwing moth bore into the base of
  • the tree.
Reasons for Control
  • Trees decline in health, becoming more susceptible to disease and other pest infestations.
  • Life span of tree is significantly reduced.
Control Notes
  • Once borers are inside the tree they cannot be controlled.
  • Preventative basal treatment of trees in mid-June and mid-July can be effective.
  • Timing will vary from year-to-year. 
  • Large commercial peach operations can use pheromone mating disruption to reduce infestation.
