Abstract

MARTINEZ-CRUZ, Julieta et al. Leafhoppers that carry begomoviruses on roselle crop (Hibiscus sabdariffa L.). Rev. mex. fitopatol [online]. 2018, vol.36, n.2, pp.321-330. ISSN 2007-8080.  http://dx.doi.org/10.18781/r.mex.fit.1801-4.

The viruses of the Begomovirus genus have a worldwide distribution and to date it is known that they are transmitted exclusively by Bemisia tabaci. In Mexico, in 2016, a complex of begomoviruses associated with the yellowing of roselle (Hibiscus sabdariffa) was reported, in which Okra yellow mosaic Mexico virus (OYMMV) is present. The objective of this study was to know the carrier insects of begomoviruses associated with roselle. Insects were collected from plants with yellowing, vein clearing and mosaic and analyzed by PCR. Three species of leafhoppers that carry OYMMV were identified: Trypanalebra maculata, Kunzeana scimetara and Agallia excavata. In T. maculata and A. modesta, Sida golden mosaic Buckup virus (SiGMBuV) and Melon chlorotic leaf curl virus (MCLCuV) were detected, respectively. This is the first report of leafhoppers as carriers of begomoviruses.

Keywords : virus vector insects; Agallia; Trypanalebra; Kunzeana.
