| O objetivo deste estudo foi determinar as espécies de ácaros predadores associados à cultura do morango e em plantas associadas, no estado do Rio Grande do Sul. Este estudo foi conduzido nos municípios de Bom Princípio, Capitão e Lajeado em plantações de morango da variedade Oso Grande em túnel baixo. As avaliações foram feitas mensalmente entre agosto de 2002 e março de 2004. Nas plantas de morango, as amostras foram constituídas de três folhas coletadas em cada uma das 15 plantas escolhidas ao acaso, totalizando 45 folhas/campo. Nas plantas associadas, o esforço de amostragem foi de uma hora para cada planta avaliada. Ácaros das famílias Ascidae, Parasitidae, Phytoseiidae, Cunaxidae, Erythraeidae, Stigmaeidae e Tydeidae foram observados associados com o... |

| This research was carried out in twenty counties of the following regions in the state of Rio Grande do Sul: Plain, Central Depression, Plateau and Coast Plain to find out the diversity of mite predators in these places. Forty-six vegetable species were sampled, thirty species of miles of the families Anystidae, Ascidae, Cheyletidae, Cunaxidae, Phyloseiidae and Stigmaeidae were mel. The Phytoseiidae were the mite that presented the greatest diversity, being present in the majority of the sample plants. Most of the Phytoseiidae that were met belong to five species of the Euseius Wainstein, 1962 genus, the second genus of this family was Iphiseiodes DeLeon, 1966, with just one species. The Stigmaeidae come up as second family in number but fewer than... |

| The rubber tree (Hevea brasiliensis Muell. Arg.) (Euphorbiaceae) is attacked by various species of phytophagous mites in Brazil. Studies conducted in the State of Mato Grosso showed the presence of Agistemus floridanus Gonzalez, 1965 (Stigmaeidae) on rubber trees, associated with the mite Tenuipalpus heveae Baker, 1945. The aim of this work was to study the biology of that predator in the laboratory, when fed with T. heveae as prey. The study was started with 22 eggs, which resulted in 15 females reaching adult hood. To determine the effect of mating on oviposition, 30 females were used; half of those were maintained isolated and the remaining were maintained then with males during the whole adult stage. The stage of egg was the longest, with a duration of... |

| Calacarus heveae Feres, 1992 is an Eriophyidae mite described from rubber tree (Hevea brasiliensis Muell. Arg.) in the northwest region of the State of São Paulo. This mite prefers the adaxial face of the folioles and it can reduce the brightness of the leaves, turning them progressively yellow and brownish, and consequently premature fall. The aim of this work was to study the biology of C. heveae in laboratory, on detached rubber tree folioles. The study was conducted at 28±1 ºC in the photophase (12h), 25±1 ºC in the dark phase (12h), and 90±5% relative humidity. The study was initiated with a total of 59 eggs. The average duration of egg, larva and nymph stages was 5.8, 2.0 and 1.4 days, respectively. The period from egg to adult lasted 9.3 days, and... |

| Calacarus heveae Feres, 1992 é um eriofídeo descrito de espécimes coletados em plantas de seringueira (Hevea brasiliensis, Euphorbiaceae) na região noroeste do Estado de São Paulo. Esse ácaro prefere a face adaxial dos folíolos e pode causar a perda do brilho, amarelecimento, bronzeamento dessa região e a subseqüente queda prematura das folhas. O objetivo deste trabalho foi analisar a distribuição de C. heveae em seringueira, selecionar a unidade de amostragem mais representativa e desenvolver um plano de amostragem para o estudo de sua flutuação populacional. O trabalho foi conduzido com os clones PB 260 e IAN 873, respectivamente nos municípios de Itiquira e de Pontes e Lacerda, ambos no Mato Grosso. Em Itiquira, diferenças significativas foram... |

| Ácaros das famílias Eriophyidae, Tarsonemidae e Tetranychidae são citados como de importância econômica na cultura de amora-preta (Rubus fruticosus, Rosaceae), framboesa e outras frutas pequenas. Este estudo foi conduzido de novembro de 2001 a outubro de 2003 nas cultivares Brazos, Caigangue e Tupy no município de Ilópolis, Rio Grande do Sul, com o objetivo de conhecer a acarofauna e sua dinâmica populacional em amora-preta. Foram coletados 36.094 ácaros pertencentes a 11 famílias. A maioria dos ácaros coletados pertence às famílias Diptilomiopidae (80,9%) e Tetranychidae (13,9%), compostas por espécies fitófagas. Chakrabartiella sp. (Diptilomiopidae), foi a espécie mais abundante, seguida por Neotetranychus asper Feres & Flechtmann, 2000... |

| We tested the functional response of the phytoseiid predator Phytoseiulus macropilis (Banks, 1904) to different population densities of Tetranychus urticae Koch, 1836 (the two-spotted spider mite - TSSM) in the laboratory. We evaluated the curve that best fits the data obtained, based on the reduced X². The predators were obtained from leaves of Oso Grande strawberries at the municipality of Bom Princípio, state of Rio Grande do Sul, Brazil. Fifteen seemingly healthy females of P. macropilis were randomly chosen and individualized in each of the arenas with different TSSM densities. The following prey densities were tested: 1, 2, 3, 5, 10, 20, 30, 35, 45, 55, 70 and 125 females. The tests were performed in a germination chamber with photoperiod of 12 hours... |

| Phytoseiidae and Sigmaeidae are the most common predatory mites on rubber tree leaves in the State of Mato Grosso, associated with phytophagous mites of the families Eriophyidae, Tenuipalpidae and Tetranychidae. The aim of this work was to compare the effect of different kinds of food, including different species of mites commonly found on the rubber tree in Mato Grosso, and one kind of pollen, on the oviposition of the predators Agistemus floridanus Gonzalez, 1965 (Stigmaeidae), Euseius concordis (Chant, 1959) and Neoseiulus anonymus (Chant & Baker, 1965), both Phytoseiidae. Those predators are common on rubber tree leaves in Mato Grosso. For the tests with A. floridanus, discs of 2 cm in diameter of rubber tree leaves were used as substrate. Food... |
