Resumo: Texas citrus mite Eutetranychus banksi (McGregor), citrus red mite Panonychus citri (McGregor)and spider mite Tetranychus mexicanus (McGregor) (all Acari: Tetranychidae) are citrus pests that cause chlorotic spots on the leaves, provoke shoots’ death and make leaves and fruits fall. To know the population fluctuation and ecological aspects of these pests a study was conducted from July 2003 to June 2006 in a ‘Valencia’ citrusorchard situated in Chapecó, Santa Catarina State, Brazil. Biweekly the infestation of these mites was evaluatedin 20 trees counting the number of these mites on three portions of their preferred locations by the use of lenses with increase by ten times and 1cm2 of the fixed field. The results showed that the infestation of the tetranichids mite decreases during periods with more rainfall and high predatory mite incidence, and increases with higher temperature.

O ácaro-texano Eutetranychus banksi (McGregor), o ácaro-purpúreo Panonychus citri (McGregor) e o ácaro-mexicano Tetranychus mexicanus (McGregor) (todos Acari: Tetranychidae) são pragas dos citros que causam manchas cloróticas nas folhas, provocam queda de folhas e de frutas e secam as brotações das plantas. Para conhecer a flutuação populacional e aspectos da ecologia dessas pragas foi conduzido um estudo, no período de julho de 2003 a junho de 2006, em um pomar de laranjeiras ‘Valência’ situado em Chapecó, SC. Cada 15 dias, ainfestação desses ácaros foi avaliada em 20 plantas, contando o número de espécimes existentes sobre três porções de suas localizações preferenciais, mediante o uso de lentes com aumento de dez vezes e 1cm2 de campo fixo. Os resultados mostram que a infestação dos ácaros tetraniquídeos diminui em períodos chuvosos e com maior incidência de ácaros predadores e aumenta com o incremento da temperatura.
