| Neste trabalho foram identificados ácaros fitófagos e predadores associados a frutos de coqueiro de localidades do Brasil, Colômbia, Cuba, EUA, México e Venezuela. Foram encontradas três espécies de ácaros fitófagos (duas Eriophyidae, uma Tarsonemidae), quatro espécies de ácaros predadores (duas Ascidae, duas Phytoseiidae), e duas espécies de hábito alimentar pouco conhecido (uma Eupodidae, uma Tydeidae). Aceria guerreronis Keifer (Eriophyidae) foi encontrada nas amostras de Alagoas, Bahia, Minas Gerais, Pernambuco, Rio de Janeiro, Rio Grande do Norte, Sergipe e São Paulo, Brasil; e também de Cuba, EUA, México e Venezuela. Amrineus cocofolius Flechtmann (Eriophyidae) foi encontrada em amostras do Rio de Janeiro, São Paulo e Sergipe, Brasil; da Colômbia e... |

| Aceria guerreronis Keifer é considerada uma das principais pragas do coqueiro no mundo. Dentre os Phytoseiidae relatados nessa cultura, Amblyseius largoensis (Muma) tem sido encontrado associado a A. guerreronis. Com o intuito de verificar se A. largoensis se alimenta de A. guerreronis, foi estudada a biologia desse predador com diferentes fontes de alimento, incluindo A. guerreronis. Foram avaliadas três dietas [Tetranychus urticae Koch + pólen de mamona (Ricinus communis L.) + mel a 10%, A. guerreronis + pólen + mel e A. guerreronis isoladamente], avaliando-se o desenvolvimento, sobrevivência, oviposição, razão sexual e longevidade de A. largoensis a 27ºC, 60 ± 5% de umidade relativa e fotofase de 12h. Tabelas de vida de fertilidade foram construídas. A... |

| O presente estudo teve como objetivo caracterizar a diversidade de ácaros em cafeeiros da cultivar Mundo Novo em duas importantes regiões produtoras (Jeriquara e Garça) do Estado de São Paulo. Para tanto, foram coletadas amostras quinzenais de folhas, ramos e frutos, entre abril de 2001 e junho de 2003, do terço médio de 10 plantas tomadas ao acaso em cada campo. De cada planta foram tomadas 12 folhas (cada uma do terceiro ou quarto par a partir da extremidade distal de um ramo), 12 ramos (25 cm apicais) e 100 frutos. Foram coletados no total 13.052 ácaros nos dois locais estudados, sendo 7.155 em Jeriquara e 5.897 em Garça. De um total de 108 espécies de ácaros coletados de plantas de café neste estudo, 45 espécies foram observadas em ambos os locais... |

| This study was conducted to evaluate the diversity of rhodacaroid mites in litter and soil samples from "Mata Atlântica" and "Cerrado", e ecosystems of the state of São Paulo, Brazil. A total of 969 adult rhodacaroids were collected, 913 in the Mata Atlântica and 56 in the Cerrado. Representatives of three rhodacaroid families were from: Ologamasidae, Rhodacaridae and Digamasellidae. Most numerous groups were ologamasids in the Mata Atlântica and rhodacarids in the Cerrado. Mites from both ecosystems represented 12 genera of Ologamasidae, two of Rhodacaridae and one of Digamasellidae. A total of 13 genera were found in litter samples and seven in soil samples of Mata Atlântica. The most common genera in this ecosystem were Neogamasellevans Loots &... |

| Eriophyoid mites are commonly associated to palm trees, although few of them have been reported causing economic damage to those plants. One exception is Retracrus johnstoni Keifer, a pest of Bactris gasipaes Kunth, plant used for palm heart production. R. jonhstoni is frequently found in large numbers on Arecaceae in southeast Brazil. The biology of this mite was studied under laboratory condition. Sections of leaves of the palm tree Syagrus romanzoffiana (Cham.) Glassman, with ca. 15 leaflets, were kept alive by maintaining their bases in distilled water. Ca. 20 field collected adults of R. johnstoni were transferred onto each leaflet for oviposition. After 24h, mites were removed, leaving only one egg laid. Once a day, the eggs and the subsequent stages... |

| This work reports the occurrence of mites predominantly predatory, phytophagous and with varied feeding habits on plants of the Atlantic Forest vegetation type of the State of São Paulo. The objective was to estimate the possible role of the Atlantic Forest vegetation as reservoir of these groups of mites which are also found on plants of agricultural importance. Samples were taken from 187 plant species belonging to 73 families in three vegetation types of the Atlantic Forest from February of 2001 to October of 2002. A total of 2,887 mites belonging to 163 morpho-species of 16 families were collected. Mite diversity was high, especially of predatory mites; these corresponded to 1,562 specimens of 92 morpho-species. Within this group, Phytoseiidae... |

| This study determined the main mite species on rubber trees (clone RRIM-600) in Piracicaba, southeast of São Paulo State, from June 2002 to May 2003 and evaluated the possible relation between them. It was conducted in a plantation of 5 ha on 11 year old trees, 15 m high, surrounded with crops as pearl millet, cotton, bean or corn. Samples were taken monthly and consisted of five leaflets, five petioles (only from October 2002 on) and five terminal sections of twigs (10 cm) from 15 rubber trees. All mites of one leaflet, one petiole and one twig section of each plant were mounted for identification to genera/species to estimate the proportional occurrence of each species. A total of 84,850 mites belonging to 38 species of 34 genera and 16 families were... |

| Aceria guerreronis Keifer can cause severe damage to coconuts in several countries around the world. Rare studies have been conducted to determine the predatory mites associated with A. guerreronis in Brazil. The study evaluated the prevalence of A. guerreronis and associated predators on the bracts and on the surface of the fruits underneath the bracts, for 12 months, on coconut palms grown along the coast of the States of Alagoas, Paraíba and Pernambuco, Northeastern Brazil. Mites of 10 families were found, but by far the most abundant species was A. guerreronis, corresponding to 99.5% of the mites collected. The prevailing species amongst the predators were the Phytoseiidae mites Neoseiulus baraki (Athias-Henriot) and Neoseiulus paspalivorus (De Leon).... |

| The occurrence of the tomato red spider mite (Tetranychus evansi Baker & Pritchard) and predatory mites on four of the most abundant native solanaceous plants in coastal Pernambuco, Brazil, was evaluated. Monthly samples were collected from mid September 2002 to late May 2003 in Aliança, Carpina, Camaragibe, Goiana, Igarassu and Recife. A total of 5,485 mites of more than 27 species were found, of which the most common were the phytophagous species T. evansi and Brevipalpus phoenicis (Geijskes) (Tenuipalpidae), and the predaceous species Asca sp. (Ascidae), Phytoseius guianensis De Leon and Paraphytoseius orientalis (Narayanan, Kaur & Ghai) (both Phytoseiidae). Negative indexes of association were determined between T. evansi and each of... |

| This work reports the Stigmaeidae mites from native plants of the family Arecaceae, in areas of Atlantic Forest in the State of São Paulo. Samplings were conducted once in each season of the year 2000 in Cananéia, Pariquera-Açu, Piracicaba and São Pedro, on nine native species of palm trees. Two new species of Stigmaeidae were found and described, Agistemus palmae n. sp. and Agistemus caissara n. sp. Based on specimens from the State of Mato Grosso, Brazil, immature stages of Agistemus floridanus Gonzalez-Rodriguez, 1965 are described for the first time, while adult males and females of the same species are redescribed |

| The objective of this study was to characterize epizootics of Neozygites sp. by investigating the relationship between the pathogen, the host, Mononychellus tanajoa (Bondar) (Cassava green mite = CGM), and climatic factors. Epizootics were studied from March through October 1994 in nine cassava fields at Piritiba, state of Bahia, Brazil. In all fields the pathogen appeared when CGM density was moderate to high. Infected CGM were first detected in northwestern fields, with an apparent progression to the southeast. The onset of the epizootic in the earliest field was observed 23 days prior to the onset of the epizootic in the latest field. During the epizootic phase of most fields (late May to late June), daily mean RH ranged from 70% to 79% and daily mean... |
