Leafroller damageLeafroller damage

Hosts:  all fruit trees

  Leafrollers (obliquebanded, fruittree) are minor pests of all fruit trees.  Depending on the species, they overwinter as pupae or eggs and emerge in spring.  Only the obliquebanded leafroller has more than one generation.

  Rolled, chewed leaves; dimpling or scarring on fruit.

  Look for rolled leaves at shoot terminals starting in late May.

Treatment Threshold:
  No threshold determined.

Degree Day Model:
  Obliquebanded leafroller has a model but because it is such a minor pest, it is not used.

Management Considerations:
  Leafroller populations are suppressed by insecticides applied for control of codling moth.
