Tomato spotted wilt virus(TSWV) is a worldwide distributed pathogen with a large number of host plants. The distribution of the virus in Europe depends onThysanopteravector species (mainlyThrips tabaciandFrankliniella occidentalis) and its perennial weed hosts. In the present work the occurrence of natural virus infections of 29 weed species to TSWV were tested using DAS ELISA. Thrips transmission of TSWV was also studied to different plant species usingT. tabaci. Adult vectors were collected from TSWV infected tobacco plants. Natural transmission byT. tabacion tobacco,Ambrosia artemisiifoliaandPelargonium zonalewas also demonstrated. Two TSWV infected weed species (Asclepias syriacaandSonchus arvensis) were found as new natural host of TSWV. The distribution of TSWV and yield losses can be reduced only by the control of thrips vectors and reservoir weeds.
