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

ABSTRACT
Huanglongbing (HLB) or greening is currently
considered the disease with the greatest
destructive potential in citriculture worldwide.
Brazil is a large citrus producer, and HLB harms
and puts the entire production chain of the crop
in the country at risk, causing serious losses.
The fall of symptomatic fruits and reduced
quality and productivity can be highlighted as
characteristics of this disease. The ability of the
vector insect, the psyllid Diaphorina citri, to
disperse between peripheral areas (borders), in
addition to the ability of this pathogen to spread
by insects developed on contaminated plants,
demands organization for the management of
disease control, making such an act very
difficult. In this sense, the present work had as
objective to evaluate the HLB indexes, in the
total area of properties in the region of
Araraquara, SP. Inspections were carried out on
the reports provided by Fundecitrus and the data
obtained were submitted to descriptive analysis
to assess the frequency of occurrence of the
disease. As a result, it was observed that
sampling research is extremely important and
efficient in combating the disease, especially at
