Abstract
The Tomato yellow ring virus (TYRV, family Bunyaviridae, genus Tospovirus) was found for the first time in greenhouses of Shiraz in the southern province of Fars, Iran, in 2007. TYRV, like other tospoviruses, is transmitted by thrips. Many factors affect the transmission efficiency of thrips-borne viruses such as thrips species or belonging to different populations. In this study, we evaluated the transmission efficiency of TYRV by different populations of two thrips species, Frankliniella occidentalis (Pergande) and Thrips tabaci (Lindeman) on different host plants. Transmission experiments were made setting newly hatched larvae (≤4 h) for acquisition on systemically infected leaves of Petunia hybrida, Nicotiana tabacum and Lycopersicon esculentum. The capacity of thrips to transmit the virus was assessed by use of the petunia leaf disc technique. Results by the double antibody sandwich enzyme-linked immunosorbent assay showed that different populations of both species could transmit this isolate to an i...
