1. SCS 438 Zafira - a new plum cultivar resistant to leaf scald (Xylella fastidiosa)
Abstract ‘SCS438 Zafira’ is a novel plum cultivar, adapted to southern Brazil. It produces high-quality fruits, very similar to ‘Fortune’, the standard mid-season cultivar. Its main advantage is the resistance to leaf scald. Apparently, the mechanism of resistance blocks the transmission of the bacteria by natural insect vectors (sharpshooters).

2. Survey of potential sharpshooter and spittlebug vectors of Xylella fastidiosa to grapevines at the São Francisco River Valley, Brazil
Survey of potential sharpshooter and spittlebug vectors of Xylella fastidiosa to grapevines at the São Francisco River Valley, Brazil. Pierce's disease of grapevines, caused by Xylella fastidiosa, is a serious problem in some regions of North America, not yet reported in Brazil. In this study, a survey of potential sharpshooter (Hemiptera, Cicadellidae, Cic

3. Análise faunística de cigarrinhas (Hemiptera: Cicadellidae) na cultura da videira no Rio Grande do Sul
In some American countries, grapevines are affected by Pierce's disease (PD), which is caused by a particular strain of Xylella fastidiosa not yet reported in Brazil. In order to investigate the potential for PD spread in Brazil in case of pathogen introduction, we conducted a faunistic analysis of leafhoppers (Hemiptera: Cicadellidae) associated to vineyard

4. Análise faunística e flutuação populacional de cigarrinhas (Hemiptera: Cicadellidae) potenciais vetoras de Xylella fastidiosa em pomares de ameixeira nos estados do Rio Grande do Sul e São Paulo, Brasil / Faunistic analysis and seasonal fluctuation of sharpshooters (Hemiptera:Cicadellidae) that are potential vectors of Xylella fastidiosa in plum orchards in Rio Grande do Sul and São Paulo states, Brazil
The plum leaf scald (PLF) is a major threat for plum production in Brazil. PLF is caused by the bacteria Xylella fastidiosa which is transmitted by sharpshooter leafhoppers (Hemiptera: Cicadellidae, Cicadellinae). In this investigation, we surveyed the Cicadellinae species associated with plum orchards located in Rio Grande do Sul (RS) and São Paulo (SP) st

5. Bacterial community associated to sharpshooters (Hemiptera: Cicadellidae) insect vectors of Xylella fastidiosa / Comunidade bacteriana associada às cigarrinhas (Hemiptera:Cicadellidae), insetos vetores de Xylella fastidiosa
A Clorose Variegada dos Citros (CVC), doença que causa graves prejuízos à citricultura no estado de São Paulo, é causada pela bactéria Xylella fastidiosa que é transmitida pelas cigarrinhas Bucephalogonia xanthophis (Berg), Dilobopterus costalimai (Young), Acrogonia citrina (Marucci &Cavichioli) e Oncometopia facialis (Signoret). Durante a alimentaç�

6. Xylella fastidiosa - adhesion and colonization in xylem vessels of sweet orange, coffee, plum and tabacco, and insect vectors and formation of biofilme on polystyrene surface. / Xylella fastidiosa adesão e colonização em vasos do xilema de laranjeira doce, cafeeiro, ameixeira, fumo e espécies de cigarrinhas vetoras e formação de biofilme sobre película de poliestireno.
X. fastidiosa is a xylem-limited bacterium that has been affecting a high number of plants in Brazil and in the world. A lot of researches were already accomplished on this bacterium, but little is known regarding the adhesion, colonization and expression of the symptoms in plants. The objectives of this work were: a) through the use of electron microscopy a

7. Epidemiology of citrus variegated chlorosis in state of São Paulo. / Epidemiologia da clorose variegada dos citros no Estado de São Paulo.
This work aimed to evaluate the progress and spatial pattern of Citrus Variegated Chlorosis (CVC) in three regions in the state of São Paulo, Brazil. By bimonthly visual assessments three Pêra sweet orange/ Rangpur lime orchards in three regions (Northwest, Center and South) were mapped from july 1998 to december 2000. Progress was evaluated by fitting nin

8. Espécies e abundância de cigarrinhas e psilídeos (Homoptera) em pomares cítricos
Leafhoppers and psyllids species which occur in citrus ecosystem were studied in the Sao Paulo State. The capture was realized with a portable vacuum sampler. Leafhoppers of the Cercopidae, Cicadellidae, Cixiidae, Delphacidae, Derbidae, Flatidae, Fulgoridae, Membracidae, Nogodinidae, and Psyllidae (Hemiptera) family were collected. The main family was Cicade
