| seasonal abundance and natural inoculativity of insect vectors of xylella fastidiosa in oklahoma tree nurseries and vineyards. | xylella fastidiosa is the causative agent of diseases of perennial plants including peach, plum, elm, oak, pecan, and grape. this bacterial pathogen is transmitted by xylem-feeding insects. in recent years, pierce's disease of grape has been detected in 10 counties in central and northeastern oklahoma, prompting further investigation of the disease epidemiology in this state. we surveyed vineyards and tree nurseries in oklahoma for potential insect vectors to determine species composition, infec ... | 2015 | 26331482 |
| seasonal abundance and spatio-temporal distribution of dominant xylem fluid-feeding hemiptera in vineyards of central texas and surrounding habitats. | a survey of xylem fluid-feeding insects (hemiptera) exhibiting potential for transmission of xylella fastidiosa, the bacterium causing pierce's disease of grapevine, was conducted from 2004 to 2006 in the hill country grape growing region of central texas. nineteen insect species were collected from yellow sticky traps. among these, two leafhoppers and one spittlebug comprised 94.57% of the xylem specialists caught in this region. homalodisca vitripennis (germar), graphocephala versuta (say), an ... | 2008 | 18801258 |
| seasonal increase of xylella fastidiosa in hemiptera collected from central texas vineyards. | yellow sticky traps were placed in six vineyards in central texas from 2003 to 2006 and in locations outside the vineyards in 2004-2006. in total, 72 collections on 55 dates were examined. xylem fluid-feeding insects were removed and identified to species and then analyzed by polymerase chain reaction to determine the presence or absence of xylella fastidiosa wells et al. of the 1318 insects removed, 13 species were found, dominated by homalodisca vitripennis (germar), clastoptera xanthocepahala ... | 2009 | 19886437 |
| cicadomorpha insects associated with bacterial leaf scorch infected oak in central new jersey. | potential insect vectors for transmission of oak leaf scorch caused by xylella fastidiosa wells et al., in pin and red oaks in new jersey were surveyed by placing yellow sticky card traps in tree canopies and fogging with pyrethrin insecticide during 2002-2006. thirty-seven cicadomorpha species were collected from 20 genera in membracidae, cicadellidae, aphrophoridae, and clastopteridae. of the 12,880 potential vectors collected, 91.4% were membracidae, 6.9% were cicadellidae, and 1.7% were aphr ... | 2011 | 22251725 |
| pierce's disease of grapevines: identification of the primary vectors in north carolina. | abstract in the past 10 years, the winegrape industry in the southeastern united states has experienced rapid growth; however, further expansion may be inhibited by pierce's disease (pd). epidemiological studies were conducted to identify the primary vectors of xylella fastidiosa, the cause of pd of grape, by surveying sharpshooter population dynamics in the eastern piedmont and coastal plain regions of north carolina. sharpshooter species were assessed for the presence of x. fastidiosa in the f ... | 2007 | 18943514 |
