Two new species of Tenuipalpus sensu stricto (Acari: Tenuipalpidae) from Brazil, with a discussion on the ontogeny of leg setae.

The Amazon and the Cerrado are the two largest biomes in Brazil, and combined represent nearly 70% of the natural vegetation in the country. Recent surveys of the mite fauna present in these two biomes have revealed a great number of new species. In this paper, we describe the adult females, deutonymphs, protonymphs, larvae and eggs of two new species of Tenuipalpidae (Trombidiformes: Tetranychoidea), Tenuipalpus protium sp.

A new species of Opilioacarus With, 1902 (Acari: Opilioacaridae) from Italy, and a new diagnosis of the genus.

No living Opilioacarus species have been described from Europe for more than a century since the first finding and species description in the early twentieth century. Using the material deposited in Museo Civico di Storia Naturale of Verona, Italy, it was possible to identify and describe a new Opilioacarus species and review the genus diagnosis, using the shape of setae d and setation of the preanal segment. The new species is also briefly compared with the other Opilioacarus species; Opilioacarus italicus (With, 1904) is considered a nomen dubium.

Four new species of Lorryia (Acari: Tydeidae) associated with Hevea brasiliensis Muell. Arg. (Euphorbiaceae) in Brazil.

Lorryia (Tydeinae) species are commonly found in surveys of rubber trees (Hevea brasiliensis) in Brazil, although only Lorryia formosa (Cooreman, 1958) has been formally reported from this host. In this study, we described Lorryia parvireticuli sp. nov.

A new species of Tenuipalpus sensu stricto (Acari: Tenuipalpidae) from Brazil, with ontogeny and a key to the known species.

The Cerrado is the second largest Brazilian biome, and is considered to be a "hotspot" due the great concentration of endemic species and high rate of deforestation. Surveys of the mite fauna present in this biome have revealed a great number of new species. In this paper, we describe Tenuipalpus spinosaurus sp.

Species Turnover through Time: Colonization and Extinction Dynamics across Metacommunities.

Island biogeography and metacommunity theory often use equilibrium assumptions to predict local diversity, yet nonequilibrium dynamics are common in nature. In nonequilibrium communities, local diversity fluctuates through time as the relative importance of colonization and extinction change. Here, we test the prevalence and causes of nonequilibrium dynamics in metacommunities of mites associated with rubber trees distributed over large spatial (>1,000 km) and temporal (>30-60 generations) scales in Brazil.

Phytoseiidae (Acari: Mesostigmata) from rubber tree crops in the State of Bahia, Brazil, with description of two new species.

The current study describes the results of a survey of Phytoseiidae mites conducted on a rubber tree plantation in the State of Bahia, Brazil. We present 22 species, two of which are new to science, Amblydromalus insolitus n. sp.

Changes in leaf physiology caused by Calacarus heveae (Acari, Eriophyidae) on rubber tree.

The influence of Calacarus heveae Feres on physiological processes was evaluated in two rubber tree clones. Experiments were conducted in a greenhouse with 5-month-old potted seedlings of RRIM 600 and GT 1 clones, that were either infested with C. heveae or not (non-infested control).

Seasonal suitability of three rubber tree clones to Calacarus heveae (Acari, Eriophyidae).

The suitability of rubber tree clones to Calacarus heveae was inferred from the life cycle, reproduction and survivorship of this mite. The assays were performed under controlled conditions with leaflets detached from 6-year-old plants. The development of 20 C.

[Mites (Acari) from rubber trees (Hevea brasiliensis Muell. Arg., Euphorbiaceae) and spontaneous euphorbiaceous in rubber trees cultivation].

Quarterly samples were done in 2001 on three rubber tree plantation in the northwest of the state of São Paulo. Three rubber trees of each locality were sampled. Between the rows of rubber tree four species of spontaneous euphorbiaceous were collected: Chamaesyce hirta, C.

[Influence of cerrado fragments in the distribution of mites in rubber tree crop].

The aim of this study was to verify whether fragments of cerrado influence the composition of the mite fauna on rubber trees. Five transects distant 50 m, being the first in the edge near the native areas and the last 200 m inside the crop, were established in each rubber tree crop in southern State of Mato Grosso. In each transect five plants were chosen, and seven leaves were collected from each plant.

[Mites (Acari: Arachnida) associated with Bauhinia variegata L. (Leguminosae) in northeast of State of São Paulo, Brazil].

The occurrence of mites on Bauhinia variegata L., a species introduced in Brazil as ornamental, was studied. Two plants of this species were sampled monthly from May 2000 to April 2001.

[Occurrence and fluctuation of mite populations associated with rubber tree crop neighbor of fragments of cerrado].

The basic knowledge of the seasonal occurrence of mites can supply data for elaboration of programs of ecological management to be implanted with success in the future. The objective of this study was to determine the species richness and the seasonality of mites present in two areas of rubber tree crops neighboring to native areas in Itiquira, MT. Along one year, 25 quantitative samplings were accomplished in rubber tree crop neighboring to two fragments of Cerrado (Cerradão and Mata Ripária).

[Diversity and seasonal occurrence of mites (Acari) in a rubber tree crop (Hevea brasiliensis, Muell. Arg.) in northwestern São Paulo, Brazil].

Brazilian southeastern region has soil and climate conditions suitable for the growing of rubber trees, and most part of national yield arises from São Paulo State. The aims proposed for this work were to determine the diversity, the richness and the seasonal occurrence of mites found in a rubber tree crop in a triennial survey with monthly samplings, as well as to estimate the populational density of the major phytophagous species. This study found 74,407 mites from 26 species belonging to 10 families.

Biological cycle of Lorryia formosa (Acari, Tydeidae) on rubber tree leaves: a case of thelytoky.
