| Abstract:
Tomato spotted wilt virus (TSWV) causes significant yield losses in tobacco, pepper, and tomato plantations in Hungary. The pathogen was identified by symptoms on test plants, double-antibody sandwich enzyme-linked immunosorbent assay (DAS-ELISA), and electron microscopy. Thrips tabaci and Frankliniella occidentalis are known vectors of TSWV in Hungary. T. tabaci is a native species; F. occidentalis was introduced in 1989. Positive vector transmission was made to Nicotiana benthamiana by T. tabaci collected from infected tobacco plants. Tobacco, pepper, and tomato die in the winter under Hungarian climatic conditions. The pathogen may reside in T. tabaci, in biennial and perennial herbaceous plants, or in cultivated plants grown in greenhouses. As F. occidentalis continues to spread in Hungary, the frequency of TSWV infection can be expected to increase. | |
