Tomato yellow leaf curl virus: host range and virus‐vector relationships

Abstract

The Jordanian isolate of tomato yellow leaf curl virus has a narrow host range restricted to a few solanaceous plants. Severe symptoms developed on tomatoes and Datura stramonium, whereas Nicotiana glutinosa and N. tabacum cvs Samsun and Havana 423 were infected without showing symptoms. The whitefly Bemisa tabaci is an efficient vector; a single whitefly was able to transmit the virus. The minimum acquisition and inoculation feeding periods were 60 and 30 min, respectively, and the latent period was 20–24 h. The virus was retained by Bemisia tabaci for 11 days. The host range and virus vector relationships of the Jordanian isolate are reported for the first time.
