Two year old Scots pine (Pinus sylvestris) seedlings were inoculated with 6.500 Bursaphelenchus mucronatus, kept in climatic chambers (day: 28 Grad C, 12h daylight; night: 18 Grad C, 12h, darkness), and watered only once a week. The isolate from "Kamptal" (Lower Austria) seems to be under stress conditions moderately pathogenic. All inoculated seedlings showed wilt symptoms, whereas non inoculated trees stayed healthy.
