MARTINEZ-ZUBIAUR, Yamila et al. Molecular characterization of Bemisia tabaci (Gennadius), Middle East-Asia minor one (MEAM1) invasive species in Cuba. Rev. Protección Veg. [online]. 2016, vol.31, n.2, pp. 81-86. ISSN 2224-4697.

Microsatellite markers and the mitochondrial sequence of mtCOI gene were used for the molecular characterization of the MEAM1 species of Bemisia tabaci (Gennadius) (Hemiptera, Aleyrodidae) in Cuba. Whitefly specimens collected from cucumber (Cucumis sativa L.), sugar beet (Beta vulgaris L.), tomato (Solanum lycopersicum L.), squash (Cucurbita pepo L), fruits of economic interest like papaya (Carica papaya L.), and two species of Bemisia weed hosts like American black nightshade (Solanum americanum Mill) and sage (Salvia officinalis L) were selected in non-productive ecosystems The results made evidente the presence of MEAM1 population with low molecular divergence in all hosts examined. DNA sequencing revealed the coexistence of MEAM1 with the New World (NW) species in S. officinalis L in natural habitat.

Keywords : Bemisia tabaci; MEAM1; microsatellites marker; mtCOI gene.
