“…In recent years, the general interest in D. europaea has increased due to evidence of its involvement in the transmission and epidemiology of FDp disease in grapevine in southeastern Europe (Filippin et al, ). In addition to its involvement as an alternative vector of FDp, the planthopper is also known to harbour diverse phytoplasmas belonging to the phylogenetically distant 16SrXII and 16SrII groups (Filippin et al, ; Cvrković et al, ; Mitrović et al, ).…”

The European lantern fly, Dictyophara europaea, is an alternative vector of the Flavescence dorée phytoplasma (FDp) disease of grapevine in European vineyards, enabling infection initiation from wild reservoir compartment (Clematis vitalba). Heretofore recorded rate of D. europaea FDp-infection has been very low (3%), making it less epidemiologically significant than would be expected based on reservoir plant infection rate (30%). In this study we present findings on a heavily FDp-infected D. europaea population (>60%), on the natural Wolbachia infection of populations with low FDp-infection rates (DeWo+) and on Wolbachia absence in highly FDp-infected population (DeWo−). We examine several possible causes underlying the differences in vector infection rates: (a) population genetic characteristics of D. europaea and correlation with Wolbachia strain wEur natural infections, (b) Wolbachia effects on fitness components of DeWo+ laboratory colony and (c) rate of reservoir plant FDp-infection and differences in FDp genotypes harboured by low and highly infected vector populations. The vector genetic diversity level was found to be lower in DeWo+ than in uninfected individuals and to exhibit a different evolution of fixed haplotypes. All DeWo+ populations were infected with the same strain of wEur. The FDp was found to be genetically diversified (five genotypes) but had no relation to infection rates. We did not find evidence of fitness upgrades with regard to Wolbachia infection status. Although more experimentation is needed, it seems that Wolbachia confers protection against FDp or is in competition with FDp according to the observed correlations: low FDp-infected vector populations are infected with Wolbachia and vice versa.

“…fenestratus is a known vector of safßower phyllody (Weintraub and Beanland 2006), lettuce phyllody, and wild-lettuce phyllody (Salehi et al 2006). Recently, this leafhopper was shown to transmit a phytoplasma belonging to peanut witchesÕ broom (Mitrović et al 2012) and to acquire a phytoplasma belonging to the pigeon pea witchesÕ broom group from Cichorium intybus L. (chicory; Ermacora et al 2013). By using an artiÞcial feeding-medium technique, N. fenestratus has also been shown to be positive for stolbur phytoplasma (Orenstein et al 2003) and to transmit aster yellow (Landi et al 2013).…”

Sex-Dispersal Differences of Four Phloem-Feeding Vectors and Their Relationship to Wild-Plant Abundance in Vineyard Agroecosystems

et al. 2013

Sex-dispersal differences of four phloem-feeding vectors and their relationship to wild-plant abundance were analyzed over 2 yr in two vineyard agroecosystems. Adults of Euscelis lineolatus Brullè, Neoaliturus fenestratus (Herrich-Schäffer), Psammotettix alienus (Dahlbom), and Hyalesthes obsoletus Signoret were sampled by using yellow sticky traps at two heights (20 and 150 cm) above the ground in a regular geo-referenced grid. Wild vegetation was surveyed around each sampling point. The most abundant species collected was N. fenestratus, followed by P. alienus, H. obsoletus, and E. lineolatus. Low traps were more effective in capturing the females of N. fenestratus and P. alienus and the males of all of the species, except N. fenestratus at one site. Sex ratio was male-biased for N. fenestratus in both agroecosystems at both trap heights, and only in low traps for H. obsoletus and P. alienus at one site. Insect abundance, temporal population dynamics, and dispersal patterns showed considerable fluctuations according to vineyard agroecosystems and years. In the current study, all of the four phloem-feeding vectors were not found homogeneously in the vineyards, and they were aggregated in correspondence with their herbaceous wild-plant hosts. Insects tended to disperse from the borders toward the vineyard, or vice versa Colonizing pattern was strongly affected by border vegetation, fallow fields, and vineyard ground-cover vegetation. Different plant communities were identified inside the agroecosystems, and significant correlations among insect and plant-species abundances were recorded. Data highlight the importance of understanding the dispersal patterns of vector species for the application of correct integrated pest-management strategies.
