1. 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. Insects associated with tropical foliage produced in the coffee growing region of Colombia
We conducted a survey of insects and pest management practices on 34 farms growing ornamental tropical foliage plants in the central coffee region of Colombia over two years. Tropical foliage provided habitat for a diverse range of insects. In total, phytophagous or detritivorous insects from six orders, 40 families and 62 genera were collected. The most com

4. On the identification of two Brazilian leafhoppers: redescription of Scoposcartula frontaliana comb. nov. and description of the female of S. talitae (Hemiptera: Cicadellidae: Cicadellini)
This paper deals with two species of Scoposcartula Young, 1977 that are very similar to each other externally (form and color pattern): S. frontaliana (Metcalf, 1955) comb. nov. (from the state of Bahia, NE. Brazil) and S. talitae Leal, Mejdalani & Cavichioli, 2005 (from the state of Espírito Santo, SE. Brazil). The former species, previously positioned in

5. First host record for Anteon pilicorne (Ogloblin) (Hymenoptera: Dryinidae), a parasitoid of Cicadellidae, including the corn leafhopper (Hemiptera: Cicadellidae)
For the first time the dryinid wasp Anteon pilicorne (Ogloblin) is recorded as a parasitoid of two Macrostelini leafhoppers: Balclutha rosea (Scott) and the corn leafhopper Dalbulus maidis (DeLong & Wolcott). New distributional records are presented.

6. Cigarrinhas (Hemiptera: Cicadellidae) potenciais vetoras de um fitoplasma (grupo 16SrlX) associado a sintomas de Huanglongbing dos citros, suas plantas hospedeiras e quantificação do patógeno / Potential leafhopper vectors (Hemiptera: Cicadellidae) of a phytoplasma (16SrIX group) associated with citrus huanglongbing symptoms, host plants and pathogen quantification
O Huanglongbing (HLB) é uma das mais temidas doenças da citricultura mundial, associada a bactérias do gênero Candidatus Liberibacter, que foram detectadas no Brasil em 2004. Em 2008, detectou-se outra bactéria associada a sintomas de HLB no Estado de São Paulo, que foi caracterizada como sendo um fitoplasma do grupo 16 SrIX. Fitoplasmas são molicutes

7. 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

8. Potenciais hospedeiros alternativos para o fitoplasma e o espiroplasma, agentes do enfezamento do milho, e alterações bioquímicas em plantas infectadas pelo espiroplasma / Potencial hosts for maize mollicutes, agent of corn stunt, and biochemical changes in plants infected by the spiroplasma
The maize bushy stunt and corn stunt are relevant diseases caused, respectively, by a phytoplasma and a spiroplasma (Spiroplasma kunkelii). Both kinds of stunting were reported in Brazil in the beginning of the 1970´s and became economically important in the beginning of the 1980´s, with the adoption of new techniques for maize cultivation. Although this p

9. Abundância e sazonalidade de cigarrinhas (Hemiptera, Cicadellidae, Cicadellinae) em vegetação herbácea de pomar de laranja doce, no município de Montenegro, Estado do Rio Grande do Sul, Brasil / Abundance and seasonality of leafhoppers (Hemiptera, Cicadellidae, Cicadellinae) in herbaceous vegetation of sweet orange orchard at Montenegro County, State of Rio Grande do Sul, Brazil
O presente estudo teve por objetivo conhecer a flutuação populacional e a constância de cicadelíneos presentes na vegetação herbácea de um pomar de laranja doce (Citrus sinensis (L.) Osbeck), variedade Valência, em Montenegro, RS. O levantamento foi realizado com a metodologia da rede-de-varredura, tendo início em fevereiro de 2001 e finalizando-se

10. Cauliflower stunt: molecular identification of phytoplasmas, evidence of potential vector and epidemiological analysis of the disease / Enfezamento da couve-flor: identificação molecular de fitoplasmas, evidência de potencial vetor e análise epidemiológica da doença
A couve-flor está entre as folhosas mais produzidas na região do Cinturão Verde de São Paulo. A planta apresenta alto valor nutricional para os consumidores e relevante importância econômica e social para os agricultores. Em campos comerciais, têm sido observadas plantas exibindo sintomas de enfezamento e deformação da inflorescência, além da necr

11. 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

12. Diversidad de cicadélidos y clastoptéridos (Hemiptera) en tres zonas productoras de café afectadas por Xylella fastidiosa Wells et al. en Costa Rica
A survey was conducted during 2002, 2003 and 2004 to determine the leafhopper species composition, abundance, richness, diversity, evenness, occurrence and flight activity among three coffee production zones of Costa Rica. Yellow sticky traps were used to qualify and quantify the number of aerial leafhoppers during the sampling period. A total of 82,500 indi
