Surveys of mite fauna associated with Hevea spp. have registered Lorryia mites as unidentified species, with L. formosa Cooreman, 1958 the only fully identified species. We examined 557 Lorryia specimens sampled from Hevea spp. from 26 plots distributed over 11 provinces in Brazil during the last 20 years. The analysis revealed eight species of Lorryia found on these hosts, four of them recently discovered associated with this host and three recorded for the first time in the country, besides L. formosa, which was already known on this host plant.

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. nov., collected on Protium heptaphyllum (Burseraceae), and Tenuipalpus kitajimai sp. nov., collected on an unidentified plant of the family Sapindaceae, from the Cerrado and the Amazon Rainforest, respectively. Females of these two new species bear two distinct cuticular crests on the dorsal opisthosoma, one transverse crest anteriorly and one longitudinal crest mesally. The ontogenetic changes in the idiosomal and leg chaetotaxy of all stages are presented for both species. Adult males are not known for either species.

In addition, a proposed new species, Tenuipalpus erbei sp. nov. is described from Costa Rica. Our results show that T. caudatus, T. erbei sp. nov. and another 36 known species of Tenuipalpus share a pair of lateral body projections associated with setae c3, considered a synapomorphy for the newly defined group, Tenuipalpus sensu stricto. We also show that its members share other character states, although these features are found elsewhere in Tenuipalpus and also in Ultratenuipalpus, indicating their origins are within Tenuipalpus. A list of Tenuipalpus sensu stricto species is presented.

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.

Neocarus coronatus n. sp., is described from caves and the surrounding epigean habitats from a karst area of São Desidério county, Bahia state, Brazil. A dissection procedure is presented for the better use of scarce Opilioacaridae material, especially to analyze gut contents. Sexual dimorphism is presented, mainly differences in the density of setae on the dorsal shield in the prominent triangular anterior region. Females have an ovipositor with 3 pairs of smooth digitiform projections and 6–8 eugenital setae. Adults have a palpal tibiotarsus with 4 d setae. Using Low-Temperature Scanning Electron Microscopy (LT-SEM), evaluation of the chaetotaxy (especially setal shape) and morphology are greatly improved over standard light microscopy techniques enhancing the interpretation of characters for species differentiation. Also, we discuss the fragility of microinvertebrates in cave habitats.

We discuss the taxonomic history of the genus Colopalpus Pritchard and Baker 1958, and redescribe the female, male and deutonymph of the type species, C. matthyssei (Pritchard and Baker). We provide previously unknown morphological data for C. matthyssei, in addition to complementary information on the morphology of C. nambii (Castro and Feres) obtained using low temperature scanning electron microscopy (LT-SEM). Our results show that both C. matthyssei and C. nambii share characters with the genera Tenuipalpus and Brevipalpus. Based on these findings, we propose that Colopalpus be reinstated as a valid genus. We discuss the characters shared by Colopalpus, Tenuipalpus and Brevipalpus, and also provide a list of species that are transferred to the genus Colopalpus.http://zoobank.org/urn:lsid:zoobank.org:pub:1A296CBB-4B02-41CD-86E6-1418F5A7F291

We verified infestation of Oligonychus milleri (McGregor) on plantations of Pinus caribaea (Pinaceae) and of Oligonychus ununguis (Jacobi) on plantations of Eucalyptus urophylla x Eucalyptus grandis (Myrtaceae) in State of Rondonia, Northern region of Brazil. This represents the first record of O. milleri in Brazil. Oligonychus ununguis was recorded previously, on cypress. The damage caused by these two spider mites in the plantations is described herein.

International audience; Tenuipalpus heveae Baker, 1945 was originally described from only female specimens collected on rubber trees from Belterra, State of Para, Brazil. The original description does not provide enough key information essential for accurate and consistent species identification, and thus, it is difficult to correctly identify this species. In this paper, we redescribe the female, male and immatures of T. heveae, from type and newly collected material, and include additional novel data (e.g. dorsal and ventral ornamentation, leg chaetotaxy and setal measurements) in a standardized form. In addition, we describe Tenuipalpus vieirae n. sp. based on adult females and immatures, collected on Hevea brasiliensis Muell. Arg. and H. guianensis Aubl. (Euphorbiaceae) from Manaus, State of Amazonas, Brazil. We include details of the patterns of ontogenetic setal additions for all stages (except the male of T. vieirae n. sp.) of these two species.

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., L. amazonensis sp. nov., L. fortistriata sp. nov., and L. virga sp. nov., associated with rubber trees from Brazil.

Host plant cultivar may determine the occurrence and abundance of both herbivorous arthropods and of other species that interact with them. We analysed the acarofauna in six rubber tree clones to identify the effect of plant cultivar on community organization of these arthropods. We analysed 10 plants of clones GT 1, PB 217, PB 235, PB 260, PR 255, and RRIM 600 every 14 days, on average, for one year. We recorded 352,426 mites from 43 species and 16 families. Phytophagous mites were the most abundant functional group, followed by mycophagous and predaceous mites. However, mite community structure varied between clones. Mite abundance peaked in clone PB 235, while it had the lowest level in PB 260. The highest estimated richness was found in clones GT 1 and PB 235. Clones PB 235, PR 255, and RRIM 600 were the most similar in mite species composition. Plant cultivars affected the abundance of phytophagous species, which in turn influenced the occurrence of competing species (i.e., less abundant phytophagous...

Studies to determine mite species richness in natural environments are still scarce, and have been conducted mainly in tropical ecosystems. The aim of this study was to determine the species richness of mites on two common native plants in fragments of the semideciduous seasonal forest in the Northwest of Sao Paulo State, Brazil. In each of eight fragments, 10 specimens of Actinostemon communis (Euphorbiaceae) and 10 of Trichilia casaretti (Meliaceae) were selected and marked. In total, 124 species of mites belonging to 21 families were found on the two plants. Tarsonemidae had the highest diversity (34 species), followed by Phytoseiidae (31), Tetranychidae (9) and Tenuipalpidae (8). Species accumulation curves for the two sampled plants did not reach an asymptote, even with the large sampling effort. Hence, it is estimated that a greater sampling effort may lead to an increase in species richness compared with what was found in this study. The richness of this mite fauna suggests that preservation of the...

Seasonal variation was a key parameter in metacommunity structure and population dynamics. In contrast, day and night periods and climatic factors had a low importance for most of the response variables, apart from richness that was negatively influenced by temperature. Concerning the population dynamics, time period plays an important role in predator species, but not in phytophagous species. Our results showed that phytophagous mites remain on leaves during both periods, whereas predators seemed to have partitioned their habitat, since some species had a tendency to forage on leaves during the day, while others forage at night. Our finding can be an indicative of behavioural response to intraguild predation or competition. In terms of metacommunity structure and dynamics, sampling period seemed not to affect species composition since we recorded higher turnover rates among trees than between periods in a same tree.

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. nov. (Acari: Tenuipalpidae), a new species of Tenuipalpus sensu stricto, from adult females, deutonymphs, protonymphs, larvae and eggs, collected on Terminalia argentea (Combretaceae), from the Cerrado in Brazil. Females of this new species bear a prominent longitudinal crest on the opisthosoma. The ontogenetic changes in the idiosoma and leg chaetotaxy of all stages are presented. A key to the world species of Tenuipalpus sensu stricto is provided.

International audience; Tetranychidae is an important family of phytophagous mites, with some species considered agricultural pests. Nevertheless, there are few studies about the diversity of this mite family in natural environments. Thus, the objective was to record the species of spider mites associated with plants in forest fragments located in the Northwestern of the State of São Paulo, Brazil. Thirty-eight species belonging to 14 genera of Tetranychidae were recorded. Only Tetranychus mexicanus and Eutetranychus banksi, species recorded on plants of economic interest, in some cases causing damage to crops, were abundant and frequent in the forest fragments sampled in this study. The knowledge of plants that can serve as alternate hosts or plant-traps can assist in understanding the dynamics of these mites in agroecosystems. The great diversity of Tetranychidae registered, and the limited knowledge of these mites associated with plants in natural environments, reinforces the importance of surveys carried out in forest remnants. Future studies should be conducted to increase the knowledge of spider mites in natural areas.

Our aim was to investigate the population fluctuation and the damage caused by the phytophagous mites Calacarus heveae Feres, Tenuipalpus heveae Baker, and Eutetranychus banksi (McGregor) on clones FX 2784, FX 3864, and MDF 180 in rubber tree crops from southeastern Bahia, Brazil. Moreover, we tested for the influence of climatic variables on occurrence patterns of these species throughout weekly samples performed from October to April. The infestation peaks was between mid-January and late February. The clones FX 2784 and FX 3864 had the highest infestations and more severe damage possibly caused by C. heveae, which was the most frequent and abundant species in all clones. We found that sunlight duration and rainfall were the most important factors for C. heveae while T. heveae was affected by rainfall and temperature. Eutetranychus banksi was only affected by sunlight duration. However, the best models had low goodness of fit. We concluded that the clones FX 2784 and FX 3864 had a higher susceptibility to mite attack, and the association between climatic variables and favorable physiological conditions were determinant for the population increase of the species from January to April.

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). The level of photosynthetic pigments, net photosynthetic rate, stomatal conductance, transpiration rate, changes in relative humidity between leaf surface and ambient air (Δw) and intercellular CO(2) concentration (Ci CO(2)) were evaluated. Infested plants showed significant reductions in the rate of transpiration, the rate of photosynthesis, stomatal conductance and Δw. RRIM 600 seedlings showed more pronounced physiological damage than GT 1 seedlings, indicating a lower physiological tolerance of the former clone to the mite. However, carotenoid levels were reduced only in GT 1 seedlings. Photosynthesis was probably reduced due to a decrease in stomatal opening, as indicated by reductions in transpiration rate and stomatal conductance and by the absence of differences in chlorophyll levels between treatments. Our results indicate that populations of C. heveae reduce the productivity of rubber trees. Thus, farmers must to be aware to control this mite pest in rubber tree plantations.

Plantas nativas podem abrigar uma grande diversidade de ácaros, entretanto o estado de conservação dos fragmentos onde estas plantas estão localizadas pode influenciar a estrutura da comunidade. em ambientes homogêneos a diversidade geralmente é menor devido à dominância de uma ou poucas espécies. O objetivo deste trabalho foi conhecer a acarofauna associada a Xylopia aromatica (Lam.) Mart. (Annonaceae) em dois fragmentos de floresta estacional semidecidual, sendo um rural e outro urbano. Amostramos mensalmente no período de abril de 2007 a março de 2008, sete indivíduos de X. aromatica em cada um dos dois fragmentos. Índices descritores de diversidade, dominância e de equitabilidade foram aplicados para verificar os padrões ecológicos da comunidade, além do Teste t de Student para comparar a abundância de ácaros entre os fragmentos. Foram coletados 27.365 ácaros de 37 espécies pertencentes a 11 famílias. Calacarus sp. (Eriophyidae) foi a espécie mais abundante, representando 73% do total amostrado. A abundância total foi maior no fragmento urbano (67,7%), com a diversidade atingindo somente 25% da máxima teórica prevista. Provavelmente, estes valores foram influenciados pela localização deste fragmento na área urbana, sendo mais homogêneo e submetido à presença de poluentes atmosféricos. Dessa forma, X. aromatica pode abrigar uma maior diversidade de ácaros quando inserida em um ecossistema conservado, visto que a maior diversidade de recursos disponíveis permite o estabelecimento de uma acarofauna mais rica e diversa. Mites associated to Xylopia aromatica (Lam.) Mart. (Annonaceae) in urban and rural fragments of semidecidual forest. Native plants can shelter a great diversity of mites. Notwithstanding, the conservation of the forest fragments where the plants are located can influence the structure of the mites community. Generally, in homogenous environments the diversity is lower due to the dominance of one or a few species. In this work, we studied the mite community on Xylopia aromatica (Lam.) Mart. (Annonaceae) in two fragments of semidecidual forest: one on rural and other on urban area. Seven individuals of X. aromatica were monthly sampled from April 2007 to March 2008, in each of these fragments. Descriptive indexes of diversity, dominance and evenness were applied to verify the ecological patterns of the mite community, besides the Student's t-test to compare the abundance between the fragments. We collected 27,365 mites of 37 species belonging to 11 families. Calacarus sp. (Eriophyidae) was the most abundant species, representing 73% of the total sampled. The abundance was greater in the urban fragment (67.7%), with the diversity index reaching only 25% of the theoretical maximum expected. Probably, these values might have been influenced by the location of this fragment in the urban area, being more homogeneous and submitted directly to the presence of atmospheric pollution. In this manner, X. aromatica is able to shelter a higher diversity of mites when inserted in preserved ecosystems, since the highest diversity of available resources allows the establishment of richer and most diverse mite community.

As plantas analisadas foram selecionadas com base no gradiente de altura e perímetro do tronco a 10 cm acima do solo. Foram realizadas coletas quinzenais no período de março de 2007 a março de 2008. em cada amostragem foram retiradas três folhas dos ramos externos e três dos ramos internos, ao redor da região mediana da copa de cada planta selecionada. Para comparar os padrões ecológicos das comunidades de ácaros entre as plantas, foram aplicados índices descritores da diversidade. em H. martiana, foram registrados 109.445 ácaros pertencentes a 28 espécies de 14 famílias. Nove espécies de ácaros, dentre as 19 classificadas como frequentes e acessórias, tiveram sua densidade populacional influenciada pelo tamanho da planta. Enquanto a densidade populacional de Chiapacheylus edentatus de Leon, 1962, Euseius cf. errabundus, Pronematus sp., Brevipalpus phoenicis (Geijskes, 1939) e Tarsonemus sp., apresentou correlação positiva com a altura da planta, a de Aberoptus aff. cerostructor, Euseius sibelius (De Leon, 1962), Typhlodromalus aripo de Leon, 1967 e Phytoseius nahuatlensis de Leon, 1959, apresentou correlação negativa. Não houve influência da altura da planta sobre a riqueza de espécies e densidade total de ácaros entre ramos internos e externos das plantas com diferentes alturas. As variações fisiológicas entre os indivíduos de diferentes estágios ontogenéticos de H. martiana, juntamente com fatores abióticos, podem ter influenciado a ocorrência e a distribuição dessas espécies de ácaros sobre essa planta. The mite communities on plants with different sizes of Hymenaea martiana Hayne (Leguminosae) were studied in a remnant of Mata Estacional Semidecidual in transition to Cerrado forest. The plants were selected according to the height and perimeter of trunk at 10 cm from the soil. Biweekly samples from March 2007 to March 2008 were performed, with three leaves collected from the outer and three from the inner branches at level of median canopy region for each plant selected. Diversity indexes were applied in order to verify the ecological patterns of mite community among the plants. We recorded 109,445 mites belonging to 28 species and 14 families on H. martiana. The population density of nine species of mites, among 19 classified as frequent and accessory, varied according to the plant size. While the population densities of Chiapacheylus edentatus de Leon, 1962, Euseius cf. errabundus, Pronematus sp., Brevipalpus phoenicis (Geijskes, 1939) and Tarsonemus sp. had positive correlation with the plant size, the densities of Aberoptus aff. cerostructor, Euseius sibelius (De Leon, 1962), Typhlodromalus aripo de Leon, 1967 and Phytoseius nahuatlensis de Leon, 1959 had negative correlation. There was no influence of the plant height on the species richness and total density of mites between leaves from the inner and outer branches sampled in plants with different sizes. The physiological variations between individuals of H. martiana in different ontogenetic stages, in addition to abiotics traits, might have influenced the occurrence and distribution of mites on this plant.

Rubber trees, Hevea brasiliensis, are the main source of latex in the world, being cultivated in several states in Brazil. Calacarus heveae Feres and Tenuipalpus heveae Baker are considered the main pest mites of this crop. In this study, we evaluated the population dynamics of these two phytophagous species and of the most common predatory species during a one-year period on crops of rubber tree clones FDR 5788, CDC 312 and PMB 01, located in Igrapiúna, State of Bahia, northeastern Brazil. The results indicate that outbreaks of C. heveae and T. heveae occur from January to May. Population densities vary among clones, being lower on FDR 5788. Amblyseius perditus Chant and Baker (Phytoseiidae), Parapronematus sp. (Iolinidae) and Agistemus pallinii Matioli, Tavares and Pallini (Stigmaeidae) were the most abundant and frequently encountered predacious species. The population dynamics of these predatory species were related to the abundance of the phytophagous mites. However, the efficacy of these predators to mitigate infestations of phytophagous mites under natural conditions is unresolved due to the high reproductive rate of the phytophagous species.

Três observações diárias foram realizadas, acompanhando-se o desenvolvimento de 60 ovos e de sua prole em folíolos de cada um dos clones, para verificação da oviposição das fêmeas e dos estágios de desenvolvimento. A partir dos dados obtidos, foi elaborada uma tabela de vida de fertilidade. Os ácaros criados sobre folíolos de PB 235 apresentaram rápido ciclo biológico, com menor tempo gasto, em dias, para duplicar sua população (TD) e os maiores valores para a produção de ovos, longevidade de fêmeas, taxa líquida de reprodução (Ro), taxa intrínseca de crescimento populacional (r m) e taxa finita de crescimento populacional (λ). em GT 1 foram observados valores inferiores e o maior tempo de desenvolvimento necessαrio para atingir a fase adulta. em todos os clones estudados a fase de maior viabilidade foi a deutoninfal, enquanto a menor, a larval, como evidenciado tambιm pelas curvas de sobrevivência, que indicaram maior mortalidade nesse estágio juvenil. O clone PB 235 possibilitou melhor desenvolvimento para T. heveae, seguido por RRIM 600, enquanto que GT 1 foi o menos favorável ao desenvolvimento dessa espécie. Life cycle of Tenuipalpus heveae Baker (Acari, Tenuipalpidae) on leaflets from three rubber tree clones. The biological cycle of Tenuipalpus heveae Baker, 1945 (Tenuipalpidae), a potential rubber tree pest mite, was studied by the observation of individuals reared on leaflets of the clones GT 1, PB 235 and RRIM 600, in controlled environmental conditions. Three daily observations were done of 60 eggs on leaflets from each clone in order to verify the development of immature stages and the female oviposition. The fertility life table was constructed based in the collected data. Mites reared on PB 235 had faster rate of development, requiring less time in days, to double its population in number (TD), and had the highest values for egg production, female longevity, net reproductive rate (Ro), intrinsic rate of natural increase (r m) and finite rate of increase (λ). Lower reproductive values and the longest time necessary to reach adult stage were recorded for the mites on GT 1. In all studied clones, the deutonymphal phase had the highest viability, while the larval phase had the lowest, highlighted by the survivorship curve that indicated high mortality during this life stage. The clone PB 235 allowed the most suitable conditions for the development of T. heveae, followed by RRIM 600, while GT 1 was the less suitable substratum to rear this mite species.

Specimens of E. banksi present morphological variability among individuals of the same population and also among populations from different host species, being commonly referred to as a polytypic species, despite the fact that studies based on meristic comparisons of these populations are lacking. Also, there is no data available in the literature on the biological life tables of E. banksi on different hosts. Specimens collected in Brazil, Guadeloupe, Martinique, Mexico, and Paraguay were investigated in order to recognize morphological patterns among populations from different localities and hosts. A redescription of the species is provided based on data both from literature and new observations. Also, the biological cycle on three hosts, experiments of hosts exchange and the possibility of interbreeding in individuals originating from different populations were evaluated. Significant differences in the morphology of the females of different populations were detected when comparing the different hosts. The length of the dorsal pairs of setae v2, sc2, c1, c3, e1 and h1 differentiated the specimens of the populations collected from Citrus sp. from those of Hevea brasiliensis Muell. Arg. and Pachira aquatica Aubl.. Herein we observed significant variation among the life cycle of this species on the three hosts studied. When a substrate different from the one where the mites were collected was used for the biological cycle essay, significant variation was observed in several parameters such as average oviposition rate, events of arrenothoky, and sex ratio. Interbreeding with populations collected from Citrus sinensis and P. aquatica resulted in no descendants, although mating was observed.

New collection records of Silvaseius barretoae (Yoshida-Shaul and Chant) are reported and a redescription of females as well as the first description of male are provided based on specimens collected in Argentina and Brazil.

A new species, Galendromus (Mugidromus) sulamericanus, is described from northwestern Sao Paulo state, Brazil, and it is included in the carinulatus species group Chant and Yoshida-Shaul, which is herein redefined to accommodate this new species. A variation in the insertion of ZV2 seta in the ventral shield was observed in individuals from the same population. A key is provided for all known species of the subgenus Mugidromus Tuttle and Muma.

Two new species, Bdella ueckermanni n. sp. and Spinibdella denheyeri n. sp. (Acari: Bdellidae), are described from plants in southeastern Brazil.

A new species of the genus Hexabdella Van der Schyff, Theron & Ueckermann, Hexabdella cinquaginta sp.n. is herein described, representing the second species of the family Bdellidae from the neotropical region. It can be distinguished from H. singula by its lobed striae on lateral margins of hysterosoma and by the leg chaetotaxy. A key to species of the genus is presented.

Phytoseiid mites have received considerable world wide attention because of their potential as natural enemies of phytophagous mites (McMurtry, 1984). The Amblyseius obtusus group Chant is the largest species group in the genus Amblyseius. Chant & McMurtry (2004) divided the group into seven subgroups based on spermathecal morphology. The andersoni subgroup of Chant & McMurtry, 2004 is characterized by a spermatheca with the calyx dish-, cup-, bell-, or V-shaped, with the length/width ratio at the mid-point of the calyx < 3:1. A total of 24 species of the andersoni subgroup are known from the Neotropical region, 13 of these from Brazil (Moraes et al., 2004). A new species of this subgroup, Amblyseius paulofariensis sp. nov., is described and illustrated in this paper, from specimens collected in the semi-deciduous forest area of “Estação Ecológica de Paulo de Faria”, a protected natural area in the State of São Paulo, southeastern Brazil, on three species of Euphorbiaceae: Acalypha diversifolia Jacq., Actinostemon communis (Müll. Arg.) and Alchornea glandulosa Poepp. & Endl.. In the region where this mites was found, the climate is of the type Cwa-Aw of Köppen, with two distinct seasons: one wet, from October to March, and the other dry, from April to September. The annual mean temperature is 25°C, with a maximum mean of 30°C and a minimum mean of 20°C (Barcha & Arid, 1971; Arid & Barcha, 1973).

Three new species of the genus Tenuipalpus (Acariformes: Tenuipalpidae), T tapiae sp. nov., T. apichai sp. nov., and T. nambii sp. nov. collected in Semidecidual Forest native plants in the northwest of the state of São Paulo, Brazil are described and illustrated. A key of the Brazilian species of Tenuipaipus based on females is presented.

The mite community has been surveyed in Seasonal Semideciduous Forest with three types of surrounding agricultural environments to test the hypothesis that abundance and richness of mites in forest fragments are influenced by the type of agricultural environment. The survey has been carried out in six fragments, divided into sets of two fragments, each one neighboring one sort of agricultural environment: sugarcane crop (FS), orange crop (FO) and pasture (FP). In each fragment, ten individuals of Actinostemon communis (Euphorbiaceae) were selected, five at the edge and five within each fragment. Iphiseiodes zuluagai, often registered in orange crops, was more abundant in the fragments neighboring such crop, as well as some species of Tarsonemidae. In this study, the Phytoseiidae were more abundant in the fragments neighboring pasture, while sugarcane crops probably favored occurrence of phytophagous mites in the neighboring fragments. Tetranychidae were less abundant in FO, which can be explained by periodical use of pesticides in the orange crops. Forest fragments are important for colonies of predators in the neighboring crops, mainly for annual crops such as sugarcane, where the close perennial environment is very important for colonization of the crop. Maintenance of those areas, besides favoring preservation of wild species of mite, is very important to increase diversity of the neighboring agricultural ecosystems. Foi estudada a comunidade de ácaros em fragmentos de mata estacional semidecidual com três tipos de ambientes agrícolas circunvizinhos para testar a hipótese de que a abundância e a riqueza de ácaros em fragmentos florestais são influenciadas pelo tipo de ambiente agrícola. O estudo foi conduzido em seis fragmentos, divididos em três conjuntos de dois fragmentos, sendo cada conjunto vizinho de um determinado tipo de ambiente agrícola: canavial (FS), laranjal (FO) e pastagem (FP). Em cada fragmento foram selecionados e marcados dez indivíduos de Actinostemon communis (Euphorbiaceae), cinco na borda e cinco no interior do fragmento. Iphiseiodes zuluagai, registrado frequentemente em laranjais, foi mais abundante nos fragmentos vizinhos a essa cultura, bem como algumas espécies de Tarsonemidae. Neste estudo os fitoseídeos foram mais abundantes nos fragmentos vizinhos de áreas de pastagens, enquanto os cultivos de cana-de-açúcar provavelmente favoreceram a ocorrência de fitófagos nos fragmentos adjacentes. Os tetraniquídeos foram menos abundantes em FO, o que pode ser explicado pela aplicação periódica de pesticidas nos laranjais. Fragmentos florestais são importantes para a colonização de predadores nas culturas vizinhas, principalmente em culturas anuais, como a cana-de-açúcar, nas quais o ambiente perene próximo é muito importante para a colonização do cultivo. A conservação dessas áreas, além de favorecer a manutenção de espécies silvestres de ácaros é de grande importância para o aumento da diversidade nos agroecossistemas vizinhos.

As folhas foram examinadas sob estereomicroscópio e todos os ácaros encontrados, montados em lâminas e identificados e contados sob microscópio com contraste de fase. A diversidade e a uniformidade de espécies foram analisadas através dos índices de Shannon-Wiener e Pielou, respectivamente. O índice de similaridade de Morisita-Horn foi utilizado para determinar o grau de semelhança entre as áreas. A diversidade máxima teórica e a constância também foram determinadas. O índice de correlação de Pearson foi utilizado para verificar possíveis relações entre a abundância de ácaros com a pluviosidade. No fragmento urbano foram coletados 6326 ácaros pertencentes a 31 espécies, e no rural, 2330 ácaros de 25 espécies. Nos dois fragmentos, a diversidade excedeu 50% da diversidade máxima teórica, entretanto, no rural verificou-se maior diversidade. Registrou-se também, grande abundância de fitófagos, que foi maior no urbano, provavelmente como resultado do estresse das plantas favorecendo o desenvolvimento dos fitófagos. Alguns predadores apresentaram grande abundância durante a floração de M. fistulifera, provavelmente por utilizarem o pólen como alimento. A maior abundância de Euseius citrifolius Denmark & Muma, na estação seca, pode estar correlacionada com a maior disponibilidade de pólen, e não com a menor pluviosidade do período. The mites on Mabea fistulifera Mart. in two forest fragments, urban and rural, were sampled monthly during 2001. For each site and each sampling date, 20 leaves were taken from each one of three trees. The leaves were inspected under dissecting microscope and all mites collected were mounted on slides, identified and counted by using a phase contrast microscope. Diversity and eveness were analyzed using the Shannon-Wiener and Pielou index, respectively. The Morisita-Horn index described similarities between the two sites. The Maximum Theoretical Diversity and Constancy index were also determined. Possible relationships between mite abundance and rainfall were investigated by Pearson correlation. The urban area had 6326 mites belonging to 31 species, while the rural area had 2330 individuals of 25 species. In both sites, the diversity exceeded 50% of the maximum theoretical diversity, but, the rural area showed higher diversity. Both sites had abundant phytophagous mites, however the abundance was higher in the urban fragment, as a result of plant stress that created more favorable conditions for phyphagous to develop. Some predaceous showed high abundance when the trees flowered. This occurs because some phytoseiids can use pollen as food. The only significant (negative) correlation was observed between rainfall and the population of Euseius citrifolius Denmark & Muma. However, the higher population of E. citrifolius on M. fistulifera in the dry season could be mostly due to the larger abundance of pollen in that period. UNESP Depto.

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 species were found in the apical branch structures: Brevipalpus sp. (aff. phoenicis), Cheletogenes sp., Euseius citrifolius Denmark & Muma, 1970, Lorryia formosa, Pronematus sp., and diapause females of Tenuipalponychus tabebuiae Aguilar, Flechtmann & Ochoa, 1991. In September, with leaves growing again, Aceria sp. was the only species on the plant, and its abundance decreased accentuately in October. The richness and the abundance of the mite fauna were not correlated with the temperature or the precipitation. These data suggest that the plant phenology was more important than the climate in the occurrence of species.

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 to citrus trees, on neighboring rubber trees in Taquaritinga, and Tenuipalpus heveae Baker, 1945, a common species on rubber trees, on a coffee culture neighbor to the rubber trees of Pindorama. This data suggests that mites move among neighbor cultures, and can be an importam factor towards pest management and control. The diversity was small on the three cultures, as a result of the occurrence of one dominam species on each area, Calacarus heveae Feres, 1992 or T. heveae, which are considered pests of the rubber tree. The small diversity and the occurrence of dominant species are patterns expected in monocultures, systems with small environmental heterogeneity.

Cecropia pachystachya Trec. (Urticaceae) is a common pioneer plant from South America, which is found on both degraded and preserved environments. Pioneer plants are able to disperse into agricultural environments and to introduce species of mites different from those present amongst the cultivated plants. This study evaluated the mite fauna present on plants of C. pachystachya associated with 18 forest fragment sites in the Northwest region of the state of São Paulo, a region where only 3% of the native vegetation is preserved. High species richness (82 species) and abundance (3,631 specimens) of mites were recorded on the plants, with high variation in species composition among the sites sampled. Regardless the species composition, most of the sites showed predominance of species considered predators, indicating that C. pachystachya provides some type of food for these mites. The data obtained in the study suggest that this plant can be an important reservoir of predatory mites and could facilitate their dissemination from preserved environments to degraded areas or crops.

A new species, Terminalichus simplex sp. nov., is described based on adult females, deutonymphs and protonymphs, collected on Terminalia catappa L. (Combretaceae) from Thailand. The relationship of Terminalichus with other brevipalpine genera is discussed and a key to species of Terminalichus, Tenuilichus, Amblypalpus, Colopalpus and Priscapalpus is provided.

Hirsutella thompsonii (Fischer) (Ascomycota: Ophiocordycipitaceae), a fungal pathogen, often causes high mortality in populations of Calacarus heveae Feres (Acari: Eriophyidae), an important pest mite in rubber tree plantations (Hevea brasiliensis Muell. Arg., Euphorbiaceae). However, the ecological and climatic factors regulating this host-pathogen system are poorly known. We compared fungal infections in agroforestry and traditional rubber plantations to evaluate the role of native vegetation and climatic factors on infection rates of C. heveae by H. thompsonii. While the prevalence of H. thompsonii was higher in managed rubber tree plantations, the abundance of C. heveae was about three times higher in traditional plantations. Abundance of C. heveae, agroecosystem management type and microclimatic variables were responsible for driving the infection rates of H. thompsonii. Native vegetation was a source for H. thompsonii and also modified the crop's microclimate, which contributed to its maintenance in the crop fields. Therefore, appropriate management practices may enhance the effects of entomopathogens on conservative biological control of pest mites in agroforestry systems.
