Biologische bestrijding van kleine mijten in Amaryllis, tulp en bromelia

Small phytophagous mites of the family Eriophyidae and Tarsonemidae are increasingly causing serious crop damage in various ornamental and fruit crops in the Netherlands. The mites are extremely tiny and hide wel lin various plant parts, which makes the control with biological control agents very difficult. In this study a new small predatory midge was discovered, named Trisopsis tyroglyphi which shows potential to control the dry bulb mite in tulip and tarseonemid mites in bromelia and gerbera. The midges did not establish well in Amaryllis.
