A citricultura no Brasil exerce um papel de grande importância economica, social, gerando empregos, renda e desenvolvimento. O Brasil e o maior produtor mundial de citros, o Estado de Sergipe destaca-se em 5o lugar nacional em producao. Dentre os varios problemas fitossanitarios enfrentados pela citricultura brasileira esta a Clorose Variegada dos Citros (CVC), conhecida como amarelinho, causada pela bacteria Xylella fastidiosa Wells et al. A CVC foi identificada oficialmente no Brasil, em 1987, em pomares do Triângulo Mineiro e do Norte e Noroeste do Estado de Sao Paulo. No Nordeste, foi constatada em 1996 em Sergipe no municipio de Boquim, e em 1997 na Bahia, nos municipios de Rio Real e Itapicuru. O objetivo foi revisar a literatura sobre as especies de cigarrinhas vetores da CVC, e verificar se ocorrem no estado de Sergipe. Os primeiros sintomas sao vistos nas folhas, passam posteriormente para os frutos e acabam afetando toda a planta, e para serem percebidos pode levar entre 5 meses e 2 anos. Os principais vetores da X. fastidiosa em citros sao as cigarrinhas da familia Cicadellidae. No Brasil ja foram confirmadas 12 especies de cigarrinhas vetoras. Para o estado de Sergipe, sao escassas a informacoes sobre Cicadellidae vetoras, os dados sao limitados ao Litoral Norte da Bahia, com excecao de vaga citacao sobre quatro generos ( Oncometropia , Acrogonia , Dilobopterus e Homolodisca ) e tres especies ( Homolodisca ignorata Melichar, Acrogonia sp. e Homolodisca spottii Takiya, Cavichioli & McKamey). Citrus leafhoppers, Vectors of of Bacterium Xylella fastidiosa Wells et al. : Potential Pest of Citrus Crops in Sergipe State Abstract. The citrus industry in Brazil plays a role of great economic, social, generating jobs, income and development. Brazil is the largest producer of citrus, the State of Sergipe stands out in 5th place in national production. Among the many pest problems faced by Brazilian citrus is Citrus Variegated Chlorosis (CVC), known as the yellowing caused by the bacterium Xylella fastidiosa Wells et al. The CVC was officially identified in Brazil in 1987, in orchards of “Triângulo Mineiro” and North and northwest of the state of Sao Paulo. In the Northeast Region of Brazil, was found in 1996 in the municipality of Boquim Sergipe, and Bahia in 1997, the municipalities of Rio Real and Itapicuru. The aim was to review the literature on the species of leafhoppers vectors of CVC, and verify that occur in the state of Sergipe. The first symptoms are seen in the leaves, then go for the fruits and end up affecting the entire plant, and to be perceived can take between five months and two years. The main vectors of X. fastidiosa in citrus are the sharpshooters of the family Cicadellidae. In Brazil 12 sharpshooters species have already been confirmed. For the state of Sergipe, is scarce information about the Cicadellidae vectors, the data are limited to the northern coast of Bahia, except for vague quote about four genus ( Oncometropia , Acrogonia , Dilobopterus and Homolodisca ) and three species ( Homolodisca ignorata Melichar, Acrogonia sp. and Homolodisca spottii Takiya, Cavichioli & McKamey).
