Abstract:
Eriophyoidea is a well-known mite taxon of economic importance. Due to their small size, elucidating many of their bio-ecological aspects becomes a challenge. These mites are obligatory plant feeders, with high host specificity and vagrant (free living) and non-vagrant (part or whole life cycle in a host) lifestyles. The mobility (distance walked - mm, resting time - s, and number of stops) of these mites on host and non-host plant species has been investigated. Eriophyoid species were submitted to walking tests on host and non-host plants using five vagrant species and five non-vagrant species. The walking was recorded with video tracking (ViewPoint) for ten minutes. Twenty replicates were performed for each treatment (eriophyoid species and plant). There was a difference in the behavioral response of the species studied in relation to the hosts. When the species were grouped by ecological lifestyle (vagrant and non-vagrant), non-vagrant eriophyoids presented a higher mobility (higher distance walked, less resting time) than vagrant eriophyoids on their respective hosts. There was no difference in the mobility of vagrant and non-vagrant species on non-host plants. The absence of a pattern of behavioral response among the species tested here indicates that more factors are involved in the host identification and acceptance process.

Abstract:
Supplementary descriptions of an infrequently encountered species Novophytoptus stipae Keifer 1962 (Eriophyoidea, Phytoptidae) from Achnatherum speciosum (Poaceae) based on topotypes recovered from dry plant material from California is given. Comparison of topotypes of N. stipae with fresh Novophytoptus mites from Juncus tenuis and J. balticus (Juncaceae) collected in West Virginia and Ohio failed to reveal distinct morphological differences sufficient enough to establish new taxa. All studied mites are considered belonging to one species, N. stipae. This is putatively an example of polyphagous eriophyoid species inhabiting phylogenetically remote hosts. Remarks on polyphagy and dispersal modes in eriophyoids are addressed. Uncommon features of the gnathosoma and the anal region of novophytoptines were discovered under LT-SEM. These findings emphasize peculiarities of novophytoptines in relation to their endoparasitic life style and underline numerous gaps in our knowledge on anatomy and functioning of the organism of eriophyoid mites.

Abstract:
A new vagrant eriophyoid mite species of the archaic genus Pentasetacus (Schliesske 1985), P. novozelandicus n. sp., is described with the aid of conventional microscopy, confocal laser scanning microscopy and scanning electron microscopy. It was found on Araucaria heterophylla, which is an araucarian that is endemic to Norfolk Island and introduced to New Zealand. Partial sequences of mitochondrial barcode COI gene and D1–D2 domains of nuclear rDNA of two pentasetacid mites, P. araucariae (MK903025 and MK898944) and P. novozelandicus n. sp. (MK903024 and MK898943) are provided. Molecular phylogenetic analyses of full-length D1–D2 eriophyoid sequences, including GenBank sequences and newly generated sequences of pentasetacids, confirmed the monophyly of Pentasetacidae but failed to resolve the basal phylogeny of Eriophyoidea. This may be because the D1–D2 domains of 28S are hypervariable in Eriophyoidea. Moreover, in pentasetacids D1–D2 sequences are about 20% shorter than in other eriophyoids, and thus harder to align. Two types of anal lobes are described in Eriophyoidea: (1) Eriophyidae s.l. and Phytoptidae s.l. have bilaterally symmetric lobes; (2) pentasetacids have non-divided lobes. The presence of an anal secretory apparatus, comprising internal structures that have previously been described in Eriophyidae s.l. and Phytoptidae s.l., is confirmed in pentasetacid genera. The phylogeny of pentasetacids is also discussed in the context of the paleobiography of Araucariaceae.

Abstract:
In addition to true tagmata, various pseudotagmata are present in chelicerates. Greatly miniaturized and morphologically simplified phytoparasitic acariform mites of the superfamily Eriophyoidea demonstrate a distinct ability to form pseudotagmata. The prodorsum and opisthosoma are the primary divisions of the eriophyoid body. In more evolutionary derived lineages, there is a trend towards the formation of additional opisthosomal subdivisions (pseudotagmata). These subdivisions are termed here “cervix”, “postprodorsum”, “pretelosoma”, “telosoma” and “thanosoma”. Among phytoptids, only the telosomal pseudotagma is present in several sierraphytoptine genera. In diptilomiopids, pseudotagmata have not been recorded. The most diverse examples of pseudotagmatization concern vagrant mites from the family Eriophyidae. Remarkably, well developed and unusually shaped pseudotagmata are peculiar to phyllocoptines from palms, especially in the new vagrant mite Pseudotagmus africanus n. g. & n. sp., found on leaves of Hyphaene coriacea (Arecaceae) in South Africa. Pseudotagmosis is one form of body consolidation in Eriophyoidea, reducing flexibility and therefore decreasing the ability for worm-like locomotion. Consequently, the legs become more important for locomotion. The other form of body consolidation is strengthening of the exoskeleton via armoring with microtubercles, and topographical changes (e.g. formation of opisthosomal ridges and furrows). The data at hand suggest that ancestrally, eriophyoids had an elongate body comprising many annuli, which can be regarded as pseudosegments. Later, they convergently evolved various pseudotagmata via the apparent fusion of these pseudosegments. Two morphotypes of vagrant mites (“armadillo” and “pangolin”) are proposed based on the difference in the modification of dorsal opisthosomal annuli. The minimal number of dorsal annuli (six) is equal to the number of dorso-longitudinal peripheral body muscles; however, this number is unlikely to reflect the true number of segments situated behind the prodorsum in Eriophyoidea. Although legs III and IV are absent in Eriophyoidea, the cervical pseudotagmata might be reminiscent of metapodosomal segments. Future comparative myo- and neuroanatomy studies of groups of genes involved in segmentation development are necessary to reach the final conclusion on the pattern of body segmentation in Eriophyoidea.

Abstract:
The superfamily Eriophyoidea constitute a group of phytophagous mites of particular economic and evolutionary interest due to their intimate association with host plants and their agricultural importance as harmful or beneficial organisms. Studies on the Eriophyoidea fauna in Brazil started in the early 1900s with botanical works on cecidias and were continued with researchers looking for and reporting on eriophyid mites causing damage to agricultural crops. Therefore, in this annotated checklist, we compile information from just over a century on eriophyid mites reported or described from Brazil. Its purpose is to facilitate plant protection strategies and guide future work on this important group of phytophagous mites. In addition to taxonomy, we present information on host plants and general aspects of cecidia attributed to eriophyoid mites but without genus/species identification. Compilation was based on: i) literature, including papers, books, theses and congress/symposium publications; ii) specimens deposited in mite collections in Brazil. On each species we present: i) suprageneric/generic classification, synonyms and previous genus/era assignments, including references on original and/or additional descriptions; ii) type host plant and other host(s) plant(s) found in the country; iii) host relationships and remarks on symptoms; iv) localities of occurrences at States/Federal District and municipal levels; and v) host plant status in Brazil as well as biomes where they occur or are cultivated. A total of 234 valid eriophyoid mite species are recorded: 196 Eriophyidae, 20 Diptilomiopidae and 18 Phytoptidae, distributed in 92 genera. Host plants comprised 233 species, belonging to 141 genera and 56 plant families. Four new reports of eriophyoid mites in Brazil are presented based on specimens deposited in reference collections. A new combination is presented for Propeaciota secundum (Flechtmann, Amrine & Stasny) in the genus Khanthongella. In addition, data on observations and descriptions of 67 cecidias attributed to eriophyoid mites in five states and on 21 plant families are presented. Geographically, the distribution of species reports of eriophyoids around Brazil is highly uneven, with more than 64% of species (151 spp.) in the Southeast region, which surely reflects a lack of research elsewhere. Regarding host plant specificity, 77.7% are reported on only one host species, 88.9% on one host genus and 98.3% on one host family. Regarding host status 64.1% of species are exclusively associated with native host plants, 27% with naturalized or exotic cultivated host plants, and 6.4% from both native and naturalized or exotic host plants.

Abstract:
A new vagrant phyllocoptine species, Phyllocoptes bilobospinosus n. sp. (Eriophyidae, Phyllocoptinae), found on tamarisks (Tamarix tetrandra Pallas, T. smyrnensis Bunge, T. ramossisima Ledeb) in Donbass (Ukraine), Crimea, and USA is described based on conventional light microscopy and confocal laser scanning microscopy. Apart from two distinct areas of ventral cuticle bearing large, spike-like microtubercles, the new species possesses a thin translucent supracapitular plate (situated below the frontal lobe of the prodorsal shield), a short longitudinal ventral ridge anterior to the anal lobes, and unusual internal tube-like structures associated with the rectum. Careful examination of purposefully made slide mounts of partially cleared specimens revealed that adults of P. bilobospinosus possess a complex of structures associated with the rectum, including a hypertrophied, four-lobed putative anal gland and four thin tubes connected with a rectal sac. Similar tubular structures previously described in aberoptine mites of the genus Aberoptus from Brazilian Cesalpiniaceae are discussed. The synonymy of genera Aberoptus Keifer and Aceria Keifer is rejected and a new combination, Aberoptus inusitatus (Britto & Navia (in Britto et al. 2008)) n. comb., is proposed. A brief review of the anal glands of Eriophyoidea is given, including a discussion on homology and the variety of forms of the anal secretory apparatus among eriophyoid genera. Further research is needed on the anatomy of anal glands in Eriophyoidea, including transmission electron microscopy based histological analyses and additional studies of eriophyoids with well-developed secretory structures associated with the rectum. These methods will lead to a much better understanding of the evolution and homology of the anal secretory apparatus, which may render it useful for future phylogenetic studies.

Abstract:
AbstractThe wheat curl mite (WCM), Aceria tosichella Keifer, is an eriophyoid pest of cereals, and the vector responsible for transmitting wheat streak mosaic virus. Several authors have suggested cryptic species of this mite identified through morphological variation, but this has never been conclusively demonstrated. Here, we use the mitochondrial 16S rRNA gene and two nuclear markers (internal transcribed spacer 1 and adenine nucleotide translocase) to show that WCM from Australia consists of at least two separate lineages that may represent putative species. In our study, both WCM variants were widespread and the only eriophyoids found on wheat varieties. The WCM variants were also found on alternate host plants, including some plants not known to host WCM. These results have implications for the control of this pest within Australian cereal crops.

Abstract:
Eriophyoid big bud mites are key pests of hazelnuts throughout the world, although little is known of the identity and impact of the species on New Zealand hazelnut crops. The key objectives of this study were to determine the species of mite present on New Zealand crops, explore a method of monitoring mite emergence from overwintering big buds, determine the phenology of mites in relation to tree phenology and weather, and identify the optimum timing for control measures. The presence of both Phytoptus avellanae (Nalepa 1889) (Acari: Phytoptidae) and Cecidophyopsis vermiformis (Nalepa 1889) (Acari: Eriophyidae) was confirmed, the latter species being a new record for New Zealand. Preliminary diagnostic DNA sequences were determined for both species. A sticky band technique was developed to monitor mite emergence from overwintering big buds, and mite emergence was found to occur between early and late spring. Mite emergence and movement occurred when daily temperatures were greater than 15 degrees C and when mean temperatures were greater than 9 degrees C, with mite emergence increasing with temperature. It proved difficult to relate the phenology of hazelnut to mite emergence, however, the development of new buds during mite emergence was a crucial factor in the infestation of new buds. An accumulated heat sum model (DD), started at Julian date 152 and using a lower threshold temperature of 6 degrees C, predicted the onset of emergence on two cultivars and at two sites as occurring at approximately 172 DD. A regression model based on leaf number, bud height, bud width, DD and Julian date provided a more satisfactory prediction of percent accumulated mite emergence. It is recommended both peak mite emergence and the appearance of hazelnut buds should be used to optimise the time to apply control measures. Therefore, a control should be applied before buds measure 0.5 x 0.5 mm (width x height), are enclosed within the axil, and have a rounded tip, or, when 50% accumulated mite emergence has occurred, which ever occurs first. A preliminary field experiment tested the application of sulphur (40 g/10 litres of 800 g/kg No Fungus Super Sulphur) at 2, 50 and 80% accumulated mite emergence. The greatest reduction in mite numbers was achieved with an application at approximately 50% emergence. Considerable variation in mite emergence occurred between years, therefore optimum timing of controls would need to be determined by monitoring mites, new buds and weather conditions each year. Field collection of mites also identified the presence of Typhlodromus doreenae Schicha (Acari: Phytoseiidae) which would warrant further study for inclusion in an integrated mite control programme.

Abstract:
Muito pouco se conhece sobre os ácaros Eriophyoidea associados às palmeiras no Brasil e em outras partes do mundo. O ácaro do coqueiro, Aceria guerreronis Keifer (Prostigmata: Eriophyidae), representa uma das principais pragas desta cultura em diversas regiões produtoras. Informações sobre o espectro de hospedeiros, região de origem e fontes de recentes introduções deste ácaro são importantes para orientar a prospecção de agentes de controle biológico e a adoção de medidas quarentenárias. Levantamentos de ácaros Eriophyoidea em palmeiras podem fornecer novas informações sobre o espectro de hospedeiros de A. guerreronis. O conhecimento da acarofauna associada às palmeiras também pode fornecer subsídios ao reconhecimento futuro destes ácaros em cultivos comerciais de palmeiras. No presente estudo, realizou-se um levantamento de Eriophyoidea em 191 espécies de palmeiras (nativas e introduzidas) de algumas localidades da América. Foram coletadas 38 espécies de Eriophyoidea, mas A. guerreronis não foi encontrada em nenhuma das amostras analisadas, exceto no coqueiro, Cocos nucifera L.. Relatos de novos hospedeiros e novas localidades de ocorrência são apresentados. Dentre os 26 táxons identificados como novos, foram descritos três novos gêneros e 17 novas espécies. Com o objetivo de facilitar estudos futuros, foram reunidas informações, publicadas e novas (adquiridas durante o desenvolvimento deste projeto), sobre as espécies de Eriophyoidea associadas às palmeiras no mundo, e uma chave dicotômica para auxiliar na separação das mesmas foi elaborada. Visando a obtenção de informações sobre aspectos biogeográficos de A. guerreronis, foram realizadas análises filogeográficas, baseadas em seqüências de DNA ribossomal (ITS) e mitocondrial (16S e CO-I), e morfométricas, utilizando técnicas de morfometria multivariada tradicional [Análise dos Componentes Principais (ACP) e Análise de Variáveis Canônicas (AVC)] e morfometria geométrica [Análise de Deformações Relativas (ADR), utilizando a função Thin-plate splines], de 29 populações ao longo de sua área de ocorrência na América, África e Ásia. As análises filogenéticas foram realizadas utilizando-se probabilidade máxima, parcimônia máxima e inferência Bayesiana. ACPs e ADCs foram conduzidas para seis combinações de populações (Brasil; América; América & África; América & Ásia; África & Ásia e América, África & Ásia). ADR foram aplicadas às regiões do escudo dorsal, coxi-genital e ventral de A. guerreronis. As matrizes de peso das ADR aplicadas aos indivíduos de todas as populações foram analisadas através de AVC. Os resultados das análises filogeográficas e morfométricas foram concordantes e são consistentes com o possível histórico de disseminação e invasões de A. guerreronis e com a hipótese de que o coqueiro não seja seu hospedeiro original. Estes resultados sugerem que A. guerreronis apresenta origem americana, que a introdução na África ocorreu a partir de um número reduzido de indivíduos, e que possivelmente a introdução na Ásia se deu a partir de populações africanas ou tenha a mesma população fonte que estas. Visando a aquisição de espécimes de A. guerreronis para o estudo da variabilidade genética e morfológica de populações, foram inspecionadas amostras de frutos de coco de diversas localidades da América. Vários outros ácaros além de A. guerreronis foram também coletados e identificados. Os sintomas observados nos frutos infestados pelas diferentes espécies fitófagas foram descritos.
Little is known about the Eriophyoidea mites associated with palm trees in Brazil and other parts of the world. The coconut mite, Aceria guerreronis Keifer (Prostigmata: Eriophyidae), represents a major pest of this crop in several production areas. Information on host range, region of origin and sources of recent introductions of this mite are important aspects to guide prospections of biological control agents and adoption of quarantine measures. Surveys of Eriophyoidea mites on palm trees can provide new information on the host range of A. guerreronis. Knowledge on the mite fauna associated with palms can be useful in their future recognition in commercial palm crops. A survey of the Eriophyoidea on 191 palm species (native and introduced) was conducted in some localities of America in this study. Thirty-eight Eriophyoidea species were collected, but A. guerreronis was not found. Reports of new hosts and new localities of occurrence were presented. Of 26 taxa identified as new, three new genus and 17 new species were described. With the objective to facilitate future studies, published and new (acquired during development of this project) information on Eriophyoidea mites associated with palms was summarized and a dichotomous key to help in the separation of those mites was prepared. To obtain information on biogeographical aspects of A. guerreronis, phylogeographical analyses, based on ribosomal (ITS) and mitochondrial (16S e CO-I) DNA, and morphometrical analyses, using traditional multivariate morphometry [Principal Component Analysis (PCA) and Canonical Variables Analysis (CVA)] and geometric morphometry techniques [Relative Warp Analysis (RWA) through Thin-plate splines function] of 29 populations, along its occurrence area in America, Africa and Asia, were conducted. Phylogenetic analyses were conducted using maximum likelihood, maximum parsimony and Bayesian inferences. PCAs and CVAs were conducted with six combinations of populations (Brazil; America; America & Africa; America & Asia; Africa & Asia and America, Africa & Asia) were conducted. RWAs were applied to prodorsal shield, coxi-genital and ventral regions of A. guerreronis. Weight matrixes of RWA applied to specimens of all populations were analyzed through CVA. Results of phylogeographical and morphometric analyses were compatible and are consistent with the possible historic of dissemination and invasion of A guerreronis history and with the hypothesis that the coconut is not the original host of this mite. These results suggest that A. guerreronis has an American origin; that few individuals were introduced to Africa; that populations introduced to Asia probably originated in Africa or had the same source as the African populations. Aiming to acquire A. guerreronis specimens for the genetic and morphological variability studies, coconut fruits from several localities in America were inspected. Several other mites were also collected and identified. Symptoms observed on the fruits infested by different phytophagous species were described.

英文摘要 Studies were undertaken to classify the fauna of eriophyid mites collected in Taiwan alpine areas. In total 130 species (125 new species, 2 new records species, 3 old species), they were classified to 4 families, including 109 species of Eriophyidae, 14 species of Diptilomiopidae, 6 species of Nalepellidae, and 1 species of Phytoptidae; 12 new genera including Arduum n. gen, Dibrachium n. gen, Forma n. gen, Forma n. gen, Macroserra n. gen, Macrovillus n. gen, Nontuberis n. gen, Opiscavumi n. gen, Rhombus n. gen, Sceptrum n. gen, Tetrapimus n. gen, Triculmen n. gen, and Vitium n. gen; 43 old genera, including Abacarcus, Abacoptes, Acamina, Acaphylla, Acaphyllisa, Aceria, Aculodes, Anthocoptes, Anthpoda, Apodiptacus, Asetadiptacus, Brachendus, Calacarus, Caliphytoptus, Chrecidus, Circaces, Cosella, Criotacus, Dacundiopus, Diptacus, Diptilomiopus, Ditrymacus, Epicecidophyes, Epitrimerus, Flechtmannia, Keiferella, Litaculus, Monotrymacus, Neodicrothrix, Neoidiptilomiopus, Paracaphylla, Phyllocoptacus, Phyllocoptes, Phyllocoptruta, Phyllocoptyches, Rhinophytoptus, Setoptus, Sierraphytoptus, Spinacus, Stenacis, Tegonotus, Trisetacus, Vasates; 1 new subgenus, Aculodes (Umor) n. subgen; 1 old subgenus, Vasates (Metaculus). The description of eriophyid mites in this research was based on the method of Boczek’s (1987) system. The great majority of the collected eriophyid mites belonged to Eriophyidae, near 84% which is the similar result described in literatures. There were greated than 95 percent of damage caused by Eriophyidae was rust. The damaged host plants was mainly Roseaceae (about 22 species), and others included Poaceae, Caprifoliaceae, Pinaceae, Cupressaceae, Theaceae, Ericaceae and Lauraceae. Worthy to be mentioned is that 9 out of 10 recorded species of Aculodes were found in Taiwan. Fifty percent of the species of Eriophyidae distribute from 2500 to 3000 meters in altitude. Above 3500 meters altitude, the species of eriophyid mites were rare, probably due to (1) simple plant fauna (2) special enviroment of alpine areas caused morphological change of the host plant, for example, anti-waterlose, smaller leaves, thicker tissue, even developing downy hair of leaves. (3) trees are not able to grow in the weathering rock. This study mainly used light microscope and scanning electronic microscrope to observe, describe and photo the characters of Eriophyid mites.

Abstract:
The diversity of the Eriophyoidea is largely unknown and their systematic study mostly entails alpha-taxonomy which is critically important for these mites. Eriophyoid morphology is almost exclusively studied on slide-mounted specimens, and truly permanent specimen slides cannot be prepared and are eventually lost. Shortcomings in taxon descriptions are persistent, and too few morphological characters are available for systematic use, particularly for phylogenetic studies. The fragile, simplified and minute eriophyoid bodies, and the inadequacy of study methods and technology, including preparation and light microscopy, contribute to these problems. The present eriophyoid classification is widely accepted, relatively stable and useful. The major part of the classification, however, is probably artificial, and some taxon delimitations and identifications are becoming increasingly difficult. Scanning electron microscopy (SEM) is only sporadically used to supplement conventional descriptions of eriophyoid mites, and their phylogeny has hardly been studied. In the present study some aspects of eriophyoid systematics and its improvements by incorporating SEM for morphological study and phylogenetic analyses for testing and improving the naturalness of the present eriophyoid classification, are used and appraised. The morphology of about 64 species, mostly from South Africa, was studied with low-temperature (cryo) SEM. The specimens remained turgid and the shape of the mites largely unaltered. A general overview of the contribution of the SEM study towards systematic morphology of the Eriophyoidea is presented. Discrepancies between species descriptions from slide-mounted specimens and the SEM images were found. These include body form, interpretation of structures, resolution and information on minute morphology, and the presence of secretions. Some of these differences were caused by artefacts introduced with slide-mounting of specimens. The SEM study includes a comparative morphological study of the gnathosoma, including a review and appraisal of characters presently used in eriophyoid systematics. New morphological information was found, including new characters that may be of systematic use. Morphology studied with SEM should be routinely incorporated into eriophyoid descriptions, which is not presently the case. The phylogeny of the Eriophyoidea was studied at genus level, using morphological data, to test the monophyly of the present suprageneric taxa. Three data matrices with 66, 60 and 27 informative characters of 316 (including most Diptilomiopus spp.), 64 and 17 eriophyoid ingroup species respectively were analyzed with parsimony analyses, and trees were searched under different parameters. This was done to find different hypotheses regarding the taxon relationships, to roughly assess the robustness of the tree groups, and to use different approaches: a very comprehensive taxon sample, but with low ratio of characters to taxa; an exemplar species sample to improve the ratio between characters to taxa; and a very small taxon sample with a good ratio between characters and taxa, but very little inclusion of variation found in the Eriophyoidea. Most groups found were supported only by homoplasy, but many made biological sense and various potentially monophyletic groups, additional to taxa in the present classification, are proposed for further study. The robustness and convergence of these groups on monophyly are discussed. The Phytoptidae was found to be polyphyletic. Part of the Nalepellinae is probably positioned outside the remainder of the Eriophyoidea, while the rest of the Phytoptidae were positioned in smaller subgroups among the Eriophyidae. The Phytoptinae and Sierraphytoptinae, including Pentasetacus, may group together. The Eriophyidae never grouped together with much support, and the family is both polyphyletic and paraphyletic. The Diptilomiopidae was largely found to be monophyletic, with a relatively strong phylogenetic structure. The Rhyncaphytoptinae is mainly paraphyletic, and the Diptilomiopinae polyphyletic, but part of the Diptilomiopinae may be monophyletic. Three new Diptilomiopus spp. from South Africa are described as part of the study: D. faurius sp. nov. from Faurea rochetiana (A. Rich.) Pic. Serm. (Proteaceae); D. apobrevus sp. nov. and D. apolongus sp. nov. from Apodytes dimidiata E. Mey. ex Arn. (Icacinaceae). They were leaf vagrants not causing any observable symptoms.
