The Recôncavo is responsible for almost 20% of citrus production in the state of Bahia, Brazil, where the occurrence of the Citrus leprosis virus (CiLV) has been recorded, one of the most important viruses in citrus cultivation, and whose vector is the Tenuipalpidae mite (Brevipalpus phoenicis). This study is to define the minimum sample size to quantify the prevalence, incidence and spatial distribution of the mite vector in the Recôncavo Baiano (RB). Two pilot samplings were made in 145 orchards located in 13 municipalities, in April and September 2008, at the end of the drought and rainy period, respectively. In each orchard, three fruits per plant were inspected using a pocket magnifying glass (magnification10x), with a total of 21 plants/orchard, recording the presence or absence of the mite vector. Maximum prevalence (100%) of the mite was found in RB in both samplings. To estimate the incidence of infestation in plants, a minimum of 18 orchards should be sampled, and the minimum sample size was 89 orchards to estimate the infestation in fruits. Infestation of Brevipalpus was verified in 74% and 63% of the plants and in 41% and 34% of the fruits in April and September, respectively. The dispersion index (DI) was about 2.59 and 4.72, classifying the spatial distribution of orchards infested by B. phoenicis in the agro-ecological conditions of the RB as aggregated. No symptom of CiLV was detected, characterizing the RB as an area free of this virus. |
