At the end of the second larval stage, species such as WFT, onion thrips and chilli thrips often move off the host plant and drop to the ground into the growing medium where they pupate.

Continuing to elucidate the epidemiology of TSWV and to develop and deploy crops with natural and genetically engineered resistance may result in more effective management of tomato spotted wilt in the future. Interactions between tospovirusesand their plant hosts and insect vectors via RNAi pathways are likely a key determinant of pathogenicity.

TSWV has a wide host range and worldwide distribution (Sherwood et al.EPPO/CABI c). This thesis started off with a detailed description of the plant immune system and previous findings about the Sw-5 gene cluster (Chapter 1). As part of this introduction, the problems caused by tospoviruses, to which Sw-5b locus confers resistance and the characteristics of these viruses have been described.
