Resumo Português:

O huanglongbing (HLB) ou greening é considerado atualmente a doença com maior potencial destrutivo da citricultura mundial. O Brasil é um grande produtor de citrus, e o HLB prejudica e coloca em risco toda a cadeia de produção da cultura no país, ocasionando graves perdas. Podem ser destacadas como características desta doença a queda de frutos sintomáticos e redução da qualidade e produtividade. A capacidade de dispersão do inseto vetor, o psilídeo Diaphorina citri, entre áreas periféricas (bordaduras), além da capacidade de disseminação deste patógeno por insetos desenvolvidos em plantas contaminadas, demanda organização para o manejo de controle da doença, tornando tal ato muito difícil. Neste sentido, o presente trabalho teve como objetivo avaliar os índices de HLB, em área total de propriedades na região de Araraquara, SP. Foram realizadas inspeções nos relatórios fornecidos pela Fundecitrus e os dados obtidos foram submetidos à análise descritiva para avaliação da frequência de ocorrência da doença. Como resultado, foi observado que a pesquisa por amostragem é extremamente importante e eficiente no combate a doença, especialmente no início de seu aparecimento, permitindo concluir que é 1 Engenharia Agronômica.
