The aim of this work was testing of suitable methods for blackcurrant gall mite elimination from planting material by thermotherapy in warm water bath. Eight variants varying in temperature and treatment time (temperature from 40 to 55 deg C, treatment time 5 or 30 minutes) were tested. Based on the preliminary results, temperature 45 deg C and 30 minutes treatment time seemed to be a suitable method. It is concluded that higher temperatures (50 deg C and more) especially in combination with longer treatment time (30 minutes) could not be used due to higher mortality of treated black currant cuttings. Further, we recommend removing of galls infected by pest in the case of warm-water therapy of cuttings from blackcurrant gall mite infected plantation.
