Abstract:
Species from three subfamilies of Cicadellidae and one species of Cixiidae, all potential vectors of phytoplasmas, were trapped in vineyards over the course of two years. These insects were caught on yellow sticky traps during the spring; virtually none were trapped during the summer months. Molecular analysis (PCR) of selected samples of the leafhoppers and planthoppers for presence of phytoplasma DNA was conducted on most species. Neoaliturus fenestratus was the most abundant known vector species and was positive for stolbur (Stol) and aster yellows (AY) phytoplasma. Circulifer haematoceps complex, which were also positive for Stol and AY, were about 10-fold fewer than N. fenestratus. Hyalesthes obsoletus, also a known phytoplasma vector, occurred in substantial numbers only late in the season when the vines and leaves were dehiscing and turning brown, but was positive for Stol and AY. A species whose vector status is unknown (Megophthalmus scabripennis) was also caught in large numbers and was shown, by PCR analysis, to be positive for AY. Other known vector species trapped included: Anaceratagallia laevis (positive for AY), Austroagallia sinuata, Dryodurades sp. (dlabolai ?) (positive for AY), Macrosteles quadripunctulatus (positive for Stol), and Orosius orientalis. The spatial dispersion pattern of the four most abundant species were investigated by using Moran's I spatial statistic; N. fenestratus and M. scabripennis showed significant spatial patterns, whereas C. haematoceps and H. obsoletus did not.
