| [population fluctuation of sharpshooters vectors of xylella fastidiosa wells et al. in commercial citrus groves in northwestern paraná state]. | the citrus variegated chlorosis (cvc), an important disease of citrus in brazil, is caused by the bacterium xylella fastidiosa wells et al. and transmitted by xylem-feeding sharpshooters (hemiptera: cicadellidae). this study evaluated the fluctuation of populations of species of sharpshooters belonging to the tribes cicadellini and proconiini, from subfamily cicadelinae, in a commercial sweet orange [citrus sinensis (l.) osb.] grove, located in the northwest region of paraná state, brazil, in fo ... | 2007 | 17607459 |
| [natural infectivity of xylella fastidiosa wells et al. in sharpshooters (hemiptera: cicadellidae) from coffee plantations of parana, brazil]. | xylella fastidiosa wells et al., a gram-negative and xylem limited bacterium, causes significative economic on several crops, such as the leaf scorch in coffee. it is transmitted by xylem feeding insects and four sharpshooters species have been reported as vectors of x. fastidiosa in coffee. the objective of this study was to determine the natural infectivity of x. fastidiosa in five species of sharpshooters from coffee trees: acrogonia citrina marucci & cavichioli, bucephalogonia xanthophis (be ... | 2007 | 17607462 |
| retention sites for xylella fastidiosa in four sharpshooter vectors (hemiptera: cicadellidae) analyzed by scanning electron microscopy. | xylella fastidiosa is a xylem-limited bacterium that causes citrus variegated chlorosis (cvc), pierce's disease of grapevine, and leaf scald of coffee and plum and many other plant species. this pathogen is vectored by sharpshooter leafhoppers (hemiptera: cicadellidae: cicadellinae) and resides in the insect foregut. scanning electron microscopy was used to determine the retention sites of x. fastidiosa for the most common vector species in brazilian citrus groves, acrogonia citrina, bucephalogo ... | 2008 | 18288522 |
| 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 |
