CARACTERIZAÇÃO MORFOLÓGICA E MORFOMÉTRICA DE ESPÉCIES DE PRATYLENCHUS EM ÁREAS DE CULTIVO DE CANA-DE-AÇÚCAR DO ESTADO DE PERNAMBUCO

RESUMO

Os nematoides das lesões radiculares Pratylenchus spp. apresentam ampla distribuição geográfica e grande número de plantas hospedeiras. Esses endoparasitas migradores são encontrados associados à cana-de-açúcar em regiões canavieiras diversas do mundo causando doenças que induzem permanentes perdas em produtividade. A despeito deste gênero ser frequentemente relatado em áreas de baixa produtividade no nordeste do Brasil, estudos sobre espécies ocorrentes são poucos e restritos a um número muito baixo de amostras e áreas. O presente estudo teve como objetivo avaliar morfológica e morfometricamente espécies de Pratylenchus de diferentes regiões do estado de Pernambuco cultivadas com cana-de-açúcar. Amostras compostas de solo e de raízes foram coletadas de 30 fazendas de três usinas do Estado de Pernambuco. As características morfológicas externas do corpo dos nematoides das diferentes populações estudadas apresentaram valor diagnóstico compatível com aqueles obtidos na literatura nematológica, demonstrando a predominância de P. zeae (87%) na região. Populações atípicas de Pratylenchus também foram encontradas.
