Tomato yellow leaf curl disease (TYLCD) is among the most destructive tomato (Solanum lycopersicum L.) diseases around the world. TYLCD is mainly caused by Tomato yellow leaf curl virus (TYLCV) in China. To screen the hosts of TYLCV, which is required for integrated management of TYLCD, an extensive survey totaling 308 samples from 54 vegetable and weed species in 12 families infected by TYLCV was conducted during 2010-2011 in Beijing, China. Testing by multiplex PCR to detect TYLCV-Israel and TYLCV-Mld revealed Cucumis sativus, Luffa cylindrica, Lagenaria siceraria and Benincasa hispida in Cucurbitaceae, Datura stramonium, Solanum nigrum, Solanum melongena and Capsicum annuum in Solanaceae, Vigna sinensis in Leguminosae, Xanthium sibiricum, Inula britannica, Hemistepta lyrata and Eclipta prostrate in Compositae, Amaranth spinosus in Amaranthaceae and Abutilon theophrasti in Malvaceae were infected by TYLCV-Israel, while Cucurbita moschata in Cucurbitaceae, and Humulus scandens in Moracea were infected by TYLCV-Mld. The much higher incidence of TYLCV-Israel strain indicated it was prevalent in Beijing. Based on the results, removing other vegetables and weeds would help to control TYLCD, and further work would focus on host preferences and their capacity to acquire and transmit TYLCV.
