Resumo
As cigarrinhas Acrogonia sp. Acrogonia virescens, Bucephalogonia xanthophis, Dilobopterus costalimai, Oncometopia fascialis, Sonesimia grossa, Plesiommata corniculata, Homalodisca ignorata, Macugonalia leucomelas, Ferrariana trivittata e Parathona gratiosa são vetoras da bactéria Xylella fastidiosa para plantas. Com o objetivo de conhecer a fauna de homópteros potenciais vetores de X. fastidiosa para cafeeiro, foi investigada a ocorrência dessas espécies em lavouras de cinco regiões produtoras de café do Estado do Paraná. Amostragens quinzenais utilizando rede entomológica e armadilha adesiva amarela foram realizadas durante o período de novembro de 1998 a outubro de 2000. Considerando-se todas as espécies de cigarrinhas amostradas em cada região, foi constatado que mais de 9,0% são representados por indivíduos das 11 espécies de cigarrinhas transmissoras da bactéria X. fastidiosa, alcançando 21% nos municípios de Londrina, Mandaguari e Ribeirão do Pinhal. As espécies O.
fascialis, D. costalimai, B. xantophis e Acrogonia sp. foram de ocorrência constante, estando presentes em 100% das coletas em quase todos os municípios estudados. De modo geral, as espécies de cigarrinhas vetoras foram mais abundantes durante o período de primavera-verão.
Acrogonia sp. Acrogonia virescens, Bucephalogonia xanthophis, Dilobopterus costalimai, Oncometopia fascialis, Sonesimia grossa, Plesiommata corniculata, Homalodisca ignorata, Macugonalia leucomelas, Ferrariana trivittata e Parathona gratiosa are vectors of X. fastidiosa. The sharpshooters fauna associated with coffee trees is poorly know. This work was carried out to identify the species and to determine the frequence, constancy and seasonal fluctuation of these sharpshooters in coffee plantations in different regions of Paraná state. Sampling was carried out by using sweep-net and yellow stick traps in five different coffee plantations throughout the coffee regions of Paraná State, from November 1998 to October 1999. Samples were taken in each area twice a month. These eleven species represented from 9 to 21 % of the total individuals collected. Among them, the species O. fascialis and D. costalimai. Were frequent species in the majority of the coffee regions. O. fascialis, D. costalimai, B. xantophis and Acrogonia sp. were constant species, present in 100 % of the samplings. The sharpshooters vectors were usually more abundant during the spring and summer seasons.
