| infectivity and transmission of xylellua fastidiosa by philaenus spumarius (hemiptera: aphrophoridae) in apulia, italy. | discovery of xylella fastidiosa from olive trees with "olive quick decline syndrome" in october 2013 on the west coast of the salento peninsula prompted an immediate search for insect vectors of the bacterium. the dominant xylem-fluid feeding hemipteran collected in olive orchards during a 3-mo survey was the meadow spittlebug, philaenus spumarius (l.) (hemiptera: aphrophoridae). adult p. spumarius, collected in november 2013 from ground vegetation in x. fastidiosa-infected olive orchards, were ... | 2014 | 25195417 |
| transmission of xylella fastidiosa to grapevine by the meadow spittlebug. | there is little information available on xylella fastidiosa transmission by spittlebugs (hemiptera, cercopoidea). this group of insect vectors may be of epidemiological relevance in certain diseases, so it is important to better understand the basic parameters of x. fastidiosa transmission by spittlebugs. we used grapevines as a host plant and the aphrophorid philaenus spumarius as a vector to estimate the effect of plant access time on x. fastidiosa transmission to plants; in addition, bacteria ... | 2016 | 27392174 |
| seasonal fluctuations of sap-feeding insect species infected by xylella fastidiosa in apulian olive groves of southern italy. | a study on seasonal abundance of auchenorrhyncha species and their infectivity by xylella fastidiosa in the apulia region of italy was conducted to identify ideal periods for monitoring and adoption of potential control measures against insect vectors. adult populations of auchenorrhyncha species were monitored monthly over a 2-yr period from five olive groves. a total of 15 species were captured, identified, and tested for presence of x. fastidiosa by polymerase chain reaction (pcr). for three ... | 2016 | 27401111 |
| fine structure of antennal sensilla of the spittlebug philaenus spumarius l. (insecta: hemiptera: aphrophoridae). i. chemoreceptors and thermo-/hygroreceptors. | the meadow spittlebug, philaenus spumarius (l.) (hemiptera: cercopoidea: aphrophoridae), is a polyphagous species that transmits xylella fastidiosa, a bacterium associated with "olive quick decline syndrome" in southern italy. in this study, the morphology and the ultrastructure of the antennal sensilla of p. spumarius were investigated. the antennae consist of three segments: a basal scape, a pedicel and a flagellum composed of a basal enlargement (ampulla) and a long segment (filament). the pe ... | 2016 | 27664780 |
| spittlebugs as vectors of xylella fastidiosa in olive orchards in italy. | the recent introduction of xylella fastidiosa in europe and its involvement in the olive quick decline syndrome (oqds) in apulia (salento, lecce district, south italy) led us to investigate the biology and transmission ability of the meadow spittlebug, philaenus spumarius, which was recently demonstrated to transmit x. fastidiosa to periwinkle plants. four xylem-sap-feeding insect species were found within and bordering olive orchards across salento during a survey carried out from october 2013 ... | 2017 | 28275326 |
| seasonal abundance of draeculacephala minerva and other xylella fastidiosa vectors in california almond orchards and vineyards. | almond leaf scorch (als) disease is caused by the bacterium xylella fastidiosa and transmitted by xylem-feeding insects. reports of increased incidence of als-diseased trees in california prompted surveys in three almond [prunus dulcis (mill.) d. a. webb]-growing regions, from june 2003 to september 2005, to determine insect vector species composition and abundance. for comparison, sampling in and near vineyards in the san joaquin valley, california, also was completed. sampling in or near almon ... | 2011 | 21510181 |
