Oak itch mite is an emerging concern

  • Like chigger bites
  • Related to Pyemotes, the straw itch mite
  • Has been around for some time in association with workers in stored products
  • This mite is associated with oak gall midge - leaf curl midge
  • Mainly red oaks
  • Mites feed on midge larvae inside galls until they are depleted
  • Then they are left with no food in mid summer when midges leave the galls
  • May be able to control mites by controlling midges
  • After leaf drop / before leaf emergence

 

Gwen Stahnke - Washington State University
