Faunistic analysis of sharpshooters (Hemiptera: Auchenorrhyncha, Cicadellidae) in a 'Westin' sweet orange orchard

Abstract

Análise Faunística de Cicadelíneos (Hemiptera: Auchenorrhyncha, Cicadellidae) em Pomar de Laranjeira 'Westin' RESUMO -O objetivo deste trabalho foi analisar a fauna de cigarrinhas em pomar de laranjeira 'Westin' enxertada sobre limoeiro 'Cravo', em plantas com cinco anos de idade. Foram instaladas armadilhas adesivas amarelas na borda da mata, na periferia do talhão e no interior do talhão, sendo avaliadas quinzenalmente, por três anos. ABSTRACT -The purpose of this study was to analyze sharpshooter fauna in a fi ve-year-old 'Westin' sweet orange orchard. Yellow sticky traps were placed on the edge of a forest, and on the periphery and inside the citrus stand. The traps were evaluated fortnightly, for three years. The most frequent species were Acrogonia citrina Marucci & Cavichioli, Bucephalogonia xanthophis (Berg), and Oncometopia facialis (Signoret). B. xanthophis occurred more in the forest edge, especially on spring and winter. A. citrina occurred most frequently in the forest edge, especially on spring. The highest incidence of O. facialis was inside the citrus stand, on spring and summer. Other cicadellids occurred more often in the forest edge, especially on summer. A. citrina, B. xanthophis, Dilobopterus costalimai Young, and O. facialis were predominant in all places studied. A. citrina, B. xanthophis and O. facialis were super dominant, super abundant, super frequent, and constant, except inside the stand, where B. xanthophis was dominant, very abundant, very frequent, and constant. D. costalimai and Homalodisca ignorata Melichar were dominant, very abundant, and very frequent in the forest edge and in the periphery of the stand, and D. costalimai was also predominant inside the stand. Scopogonalia subolivacea (Stål) was predominant in the forest edge and inside the stand, while Plesiommata corniculata Young was predominant in the periphery (both were dominant, very abundant, very frequent, and accessory).

Diversity of Cicadomorpha (Hemiptera: Auchenorrhyncha) in Citrus Orchards in Northeastern Argentina

“…The remaining species were rare or occasional in both orchards. Similar results have been obtained by studies in Brazil Nunes et al 2007;Menegatti et al 2008;Miranda et al 2009;Molina et al 2010), where Dilobopterus costalimai Young was the dominant species; but other research has shown B. xanthophis as the most abundant and frequent species on citrus (Yamamoto et al 2001;2002;Coelho et al 2008).…”

Distribuição espaço-temporal de cigarrinhas (Hemiptera: Cicadellidae) vetores da Xylella fastidiosa em pomares cítricos

“…Para calcular a constância das espécies de cigarrinhas capturadas, foi empregado a fórmula C(%)=P/N, onde C= constância das espécies, expressa em porcentagem; P= número de coletas contendo a espécie; e N= número de coletas realizadas (COELHO et al, 2008) Nas análises geoestatisticas, foram utilizados os dados totais de captura dos insetos, ou seja, soma das espécies capturadas nas quatro estações avaliadas. Sendo o estimador de Matheron, o mais adequado para a construção do semivariograma experimental das variáveis que apresentaram distribuição normal de probabilidade dos dados.…”
