Resumo: The citrus rust mite Phyllocoptruta oleivora (Ashmead, 1879) (Acari, Eriophyidae) causes stains on fruits and leaves, reducing fruit quality and orchard production. To study the interferente of environmental factors in the population fluctuation of this pest, two six-year-old 'Valência' orange orchards were sampled fortnightly from 1997 to 2000 in the West of Santa Catarina. In each evaluation, using 10 X magnifying lenses, the number of mites was observed in lcm 2 portions, in preferential areas of the pest, of three fruits or leaves, from 20 trees in each orchard. The greatest infestation and damage occurred between February and May, characterizing this mite as one "key" citrus pest in the region. Correlation analyses of the monthly mean sum of mites observed in each evaluation in the two orchards and the monthly total rains (p), monthly total insolation (i), mean monthly wind speed (v) and mean monthly temperature for two months before the evaluation date (tmd) showed "r" values of- 0.31; 0.21; - 0.22; and 0.44, respectively. The linear regression analyses with 0.05 probability resulted in the equation = - 349,11 + 38,33 tmd - 0,86 p, with R2 = 0.32.

Para estudar as interferências dos fatores ambientais sobre a flutuação populacional deste ácaro, dois pomares de laranja 'Valência', com seis anos, situados no Oeste Catarinense, foram avaliados quinzenalmente de 1997 a 2000. Em cada avaliação, utilizando-se lentes com aumento de 10 vezes, foi observado o número de ácaros, em porções de lcm 2,em áreas de localização preferencial da praga, de três frutas ou folhas, de 20 plantas de cada pomar. As maiores infestações e danos do ácaro ocorreram entre fevereiro e maio, com populações que enquadram este acarino como sendo uma praga "chave" da citricultura regional. A análise de correlação entre a média mensal da soma de ácaros observados, em cada avaliação, nos dois pomares, e o total mensal de precipitação pluviométrica (p), o total mensal de insolação (i), a velocidade média mensal dos ventos (v) e a temperatura média mensal de dois meses antes da data de avaliação (tmd) expressaram "r" = - 0,31; 0,21; - 0,22 e 0,44, respectivamente. A análise de regressão linear, com 0,05 % de probabilidade, resultou na equação y = - 349,11 + 38,33 tmd - 0,86 p, com R2 = 0,32.Departamento de Diagnóstico e Pesquisa Agropecuária.
