| transmission efficiency of xylella fastidiosa by sharpshooters (hemiptera: cicadellidae) in coffee and citrus. | xylella fastidiosa (wells, raju, hung, weisburg, mandelco-paul, and brenner) is a bacterial pathogen transmitted by several sharpshooters in two tribes of cicadellinae (proconiini and cicadellini). here, we compared the transmission efficiency of x. fastidiosa in coffee (coffea arabica l.) and citrus [citrus sinensis (l.) osbeck] by cicadellini [bucephalogonia xanthophis (berg) and dilobopterus costalimai young] and proconiini [homalodisca ignorata melichar and oncometopia facialis (signoret)] s ... | 2008 | 18767717 |
| faunistic analysis of sharpshooters (hemiptera: auchenorrhyncha, cicadellidae) in a 'westin' sweet orange orchard. | the purpose of this study was to analyze sharpshooter fauna in a five-year-old 'westin' sweet orange orchard. yellow sticky traps were placed on the edge of a forest, and on the periphery and inside the citrus stand. the traps were evaluated fortnightly, for three years. the most frequent species were acrogonia citrina marucci & cavichioli, bucephalogonia xanthophis (berg), and oncometopia facialis (signoret). b. xanthophis occurred more in the forest edge, especially on spring and winter. a. ci ... | 2008 | 18813748 |
