Abstract

Coletas quinzenais de ácaros de ramos do Pinheiro-do-Paraná, Araucária angustifolia, em Lages, Santa Catarina, revelaram a presença, durante um ano (Setembro de 1983 a Agosto de 1984) das espécies fitófagas Oligonychus urunguis (Jacobi) e Tydeus formosus (Cooreman) e de ácaros predadores da família Phytoseiidae, dos gêneros Amblyseius e Proprioseiopsis. Também ácaros oribatídeos foram coletados durante todo o ano. De ocorrência mais restrita foram obtidos ácaros das famílias Ascidae, Bdellidae, Cheyletidae e Acaridae. O método de coleta batendo-se o material vegetal sobre tela e bandeja revelou-se pouco mais eficiente do que o emprego do funil de Tullgren.Branches of Araucária angustifolia (Bert.) 0. Kuntze trees ca. 15 years old were collected twice a month during the year September 1983 - August 1984 and processed in Tullgren funnel and by beating them over a screen on a white enamel tray, to obtain the mite fauna. Oligonychus ununguis (Jacobi) and Tydeus formosus (Coorenman) were present throughout the year, as well as the Phytoseiid species Amblyseius chiapensis De Leon, A. metapodalis El-Banhawy and Proprioseiopsis spp. No visible damage to the foliage was observed. Oribatid mites were also obtained year round. Other mites, less frequent, were Blattisocius dentriticus (Berlese), Tyrophagus putrescentiae(Schrank) and mites of the families Bdellidae and Cheyletidae. Beating produced a somewhat better result than the funnel method.
