| 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... |

| The mites of three rubber tree cultures (Cedral, Pindorama and Taquaritinga) in order to determine the abundance of populations, the richness, the diversity and the degree of similarity among the communities was studied. Twenty one species were found, five of which were common to the three cultures. The richness and the abundance were greatest at the beginning of the dry season. The composition of communities differed probably as consequence of the kind of neighboring vegetation to each area, and because of the acaricid pulverization on the culture of Taquaritinga, reductng the richness of mite species in that area. The influence of neighboring vegetation can be shown by the occurrence of Iphiseiodes zuluagui Denmark & Muma, 1972, a common species... |

| Studies were carried out on the relationship between feather mites in wild birds captured by mist nets at the Engenho Independência, county of Vicência. The captures were performed in June, September and December (1995) and March (1996). Mites belonging to the families: Analgidae, Psoroptoididae, Avenzoariidae, Proctophyllodidae e Trouessartiidae were identified to genera. The most representative genera, according to the number of hosts they were found were Pterodectes sp. (Proctophyllodidae), with eighteen and Trouessartia sp. (Trouessartiidae), with sixteen hosts, respectively. The Psoroptoididae and Avenzoariidae families were found in only one host each. The ventral face of remiges and rectrices were the main sites inhabited by mites. |

| This study reports the mite fauna associated with Tabebuia roseo-alba, a native and ornamental tree, determining the abundance and seasonal occurrence of species and the diversity of the community. Twenty three species were found belonging to 11 families, 10 of predatory habits and five phytophagous. The food habits of the eight remaining species are not known. Besides the great richness, the diversity was small, as consequence of the dominance of Lorryia formosa Cooreman, 1958 and Aculus sp., the most abundant species. These species occurred in the same microhabitat but with seasonal segregation: L. formosa was the most abundant in the dry season, while Aculus sp. occurred only in the rainy season. In August, when the plant lost its leaves, the following... |

| 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... |

| Calacarus heveae Feres, 1992 was the first eriophyid mite reported from Hevea brasiliensis Muell. Arg. This mite was first found in northwestern São Paulo State, Brazil. Feres (1998) described two additional species, Shevtchenkella petiolula and Phyllocoptruta seringueirae, from the same host and from same region. The commercial monocultural planting of the Amazonian rubber tree in the northwestern region of São Paulo State started about 18 years ago. In the Amazonian region, the native rubber tree grows dispersed between other plant species. Until now these eriophyids have been collected only on monocultural plantings. This paper reports the occurrence of C. heveae, S. petiolula and P. seringueirae on H. brasiliensis in the Amazonian Forest for the first... |

| 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... |

| Abstract The coconut mite, Aceria guerreronis Keifer (Acari: Eriophyidae), is one of the main pests of the coconut crop by attacking the fruits. Colonies can reach 10,000 mites/fruit at high infestation. A diagrammatic scale (Galvão scale) has been developed and tested by Brazilian researchers to estimate the number of mites/fruit by determining the percentage of necrotic area of the fruit surface. Our objective was to develop and validate a new diagrammatic scale based on the percentage of the damaged perimeter of the fruit at the base of the perianth, in order to facilitate and improve the quantification of A. guerreronis per fruit. Fruits were collected in an urban coconut plantation in Ilhéus, Bahia, Brazil. For the development of the new diagrammatic... |

| Abstract: Yotoco Nature Reserve is a protected area for conservation purposes, is located at 3o53'18'' N, 76o20'5'' W, in the town of Yotoco with an altitude of 1526 m. a. s. l. The present research aimed to identify the diversity of mite suborder Prostigmata associated with the rhizosphere of plants of the Natural Reserve of Yotoco. Six samplings of soil and leaf litter between the surface and 5 cm depth were done in a radius of 1 m from the stem of plants, which are representative in each location of study. Samples were taken to the laboratory in styrofoam coolers. To isolate the mites, the Berlese-Tulgren funnel was used and mites were collected in vials with 70% alcohol. For permanent mounting in microscope slides, the Hoyer medium was used. A... |

| 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. |

| Estudou-se a oviposição, desenvolvimento, fecundidade e sobrevivência de Oligonychus ilicis (McGregor) (Acari: Tetranychidae), sobre discos de folhas de cafeeiro (Coffea arabica L.) submetidos à aplicação do piretróide deltametrina. Em laboratório, deltametrina não interferiu no número de ovos postos pelas fêmeas em discos tratados; no período de incubação; na viabilidade dos ovos; e na duração do ciclo biológico da fêmea. Em contrapartida, o inseticida causou aumento na duração da fase pós-embrionária (larva-adulto) da fêmea em 17,4% e do macho em 17,2%, duração do ciclo biológico do macho em 0,7%, e afetou a sobrevivência de machos e fêmeas em até 63,9%. As fêmeas descendentes de progênies criadas sobre discos de folhas tratadas com deltametrina... |
