Life cycle/habits

  • Cyclamen mites usually come in on greenhouse plants or migrate in from strawberry plantings and are difficult to control when conditions favor their growth. 
  • The mite injects a growth regulator into foliage while feeding that causes leaves to twist and crinkle and sometimes become very large. The symptoms mimic virus injury.

Host plants

  • Cyclamen mites can be a minor pest of pepper and tomato.


  • Fruit feeding produces a dramatic russeting - usually at the stem end. 
  • Fruits appear to be covered with a very fine, brown netting that feels slightly rough.
