First report of Tomato torrado virus in Panama


Name: Tomato torrado virus

Common Names:



In February of 2008, Solanum lycopersicum (tomato) plants exhibiting unusual symptoms were observed in Panama. Molecular analysis confirmed the presence of Tomato torrado virus (ToTV) and Cucumber mosaic virus (CMV). The researchers found no difference in symptom expression between plants infected with both viruses or with ToTV alone. This is the first report of ToTV in Panama.

Issues of Concern:

ToTV, the causal agent of tomato torrado disease, is also known to infect other species in the family Solanaceae, including S. tuberosum (potato), S. lycopersicum (tomato), S. melongena (eggplant), Nicotiana tabacum (tobacco), and Capsicum annuum (pepper) (Amari et al., 2008). Natural infection of weed hosts was reported in Spain in various plant families such as Amaranthaceae, Caryophyllaceae, Chenopodiaceae, Cruciferae, Malvacae, and Polygonaceae (Alfaro-Fernandez et al. 2008). These hosts may serve as alternative hosts in close proximity to Solanaceous crop production systems.

The tobacco whitefly, Bemisia tabaci (Hemiptera: Aleyrodidae), and the greenhouse whitefly, Trialeurodes vaporariorum (Hemiptera: Aleyrodidae) are able to transmit ToTV (Amari et al., 2008). These vectors are present in the NAPPO region (CABI, 2007).

This is a newly named virus and disease problem that has also been found in Spain (Alfaro-Fernández et al., 2007), Hungary (glasshouse incursion) (EPPO, 2008), and Poland (Pospieszny et al., 2007). A related but distinct virus, Tomato marchitez virus, was recently detected and named in Mexico (Verbeek et al., 2008). Both viruses are proposed to belong to a new genus called Torradovirus (Verbeek et al., 2008).
