Un inventaire des Tetrany chidae du Brésil a été réalisé dans 15 États ainsi que dans le District Fédéral, avec 550 échantillons de 120 espèces végétales collectés. Des infestations par des acariens tétranychidés ont été confirmées dans 207 de ces échantillons. Vingt-deux espèces appartenant à sept genres de la sous-familles des Bryobiinae et Tetranychinae ont été identifiées chez 58 hôtes différents. Trente-six nouvelles plantes hôtes pour 11 espèces ont été répertoriées au Brésil, en Amérique du sud ou dans le monde. De nouvelles localités ont été enregistrées au Brésil pour quatre tétranychides et une espèce a également été signalée pour la première fois en Amérique du sud. Quatre nouvelles espèces ont été découverte: deux appartenant au genre Oligonychus Berlese et deux appartenant aux genres Monoceronychus McGregor et Schizotetranychus Tragardh. La contribution à la systématique du genre Tetranychus a consisté à analyser conjointement des substuences d´ADN ribosomique (ITS) et mitochondrial (COI) de femelles de T.urticae, T. cinnabarinus (synonyme potentiel de T. urticae) et d'espèces très proches appartenant également au groupe Tetranychus sensu stricto. Cette étude a mis en évidence des incohérences ce qui nous a amené à remettre en question la fiabilité des données moléculaires concernant le groupe Tetranychus s. str. disponibles dans Genbank. Des données sur la variabilité génétique, la phylogénie et la structure de populations de T. urticae au Brésil et dans le monde sont ensuite présentées. Les résultats indiquent la présence significative d'une structuration génétique des populations de T. urticae par rapport à la localisation géographique. L´effet de la plante hôte n´est pas observé. La diversité haplotypique, inférée à partir des ces deux régions du génome (ITS et COI) est plus élevée dans les pays du pourtour méditerranéen. On a constaté la présence de deux haplotypes mitochondriaux (COI) au Brésil, l´un partagé avec la France, l´Espagne et les îles Canaries, et l´autre avec le Japon.

In this study we performed a survey of Tetranychidae mites from Brazil, including 15 States and the Federal District. A total of 550 samples of 120 different plant species were collected. Tetranychid mite infestations were confirmed in 207 samples, and 22 species belonging to seven genera of the Bryobiinae and Tetranychinae subfamilies were identified on 58 different host plants. Thirty-six new hosts were recorded in Brazil, South America and worldwide for eleven species. New localities were registered for four tetranychid genera and a new record to South America was confirmed. Four species were identified as new for science: two belonging to the Oligonychus Berlese genus and two belonging to the Monoceronychus McGregor and Schizotetranychus Tragardh genera. We analyzed and evaluated the identity of 105 Genbank accessions of ITS2 rDNA and 138 COI mtDNA sequences which were deposited as T. urticae and as fourteen other taxa morphologically close ly related to Tetranychus sensu stricto. Among the deposited sequences in…

The Tetranychidae family contains a large number of strictly phytophagous mites and includes important pests to the national and global agriculture. The two-spotted spider mite, Tetranychus urticae Koch (Prostigmata: Tetranychidae), is a cosmopolitan and polyphagous species, and is remarkable for the high losses caused to the crops. In Brazil T. urticae is one of the three main pest mites. Many aspects about systematic, biology, feeding habits, and control have been studied to this species. Although the unquestionable progress on the studies on tetranychid mites in Brazil, is important expand the research to new regions in the country in plant hosts not yet evaluated. Exploiting new areas of knowledge as molecular aspects allow to access information on genetic variability, phylogeny and genetic structure of populations may also contribute to the knowledge of this important family of phytophagous mites in the country. In this study it was conducted a survey of Tetranychidae mites on 15 States and the Federal District and 550 samples of 120 plant species were collected. Tetranychid mite infestations were confirmed on 58 plant species. New hosts to tetranychid in Brazil, South America or worldwide were reported to 11 mite species: Eutetranychus banksi (McGregor); Mononychellus tanajoa (Bondar); Oligonychus anonae Paschoal; O. mangiferus (Rahman &Sapra); Tetranychus bastosi Tuttle, Baker &Sales; T. evansi Baker &Pritchard; T. ludeni Zacher; T. mexicanus (McGregor); T. neocaledonicus André; and T. urticae Koch. New localities in Brazil were recorded to Eotetranychus tremae De Leon; O. anonae; Panonychus ulmi (Koch); and T. gloveri Baker &Pritchard. Eotetranychus smithi Pritchard &Baker was reported for the first time in Brazil. Four new species were identified as new for science: two belonging to Oligonychus Berlese genus, on grape (Vitis vinifera L.) and rose (Rosa sp.) from Minas Gerais; and two belonging to Monoceronychus McGregor and Schizotetranychus Tragardh genera, both from weeping fingergrass (Eustachys distichophylla Lag. Nees) from Rio Grande do Sul. Aiming to obtain information on genetic variability, phylogeny and structure of populations of T. urticae in Brazil and worldwide phylogenetic and molecular variance analysis (AMOVA) were conducted from DNA ribosomal (ITS) and mitochondrial sequences (COI). Samples of T. urticae from Brazil (22) and the Paleartic region (33) (France, Peninsular Spain, Canary Islands, Greece, Syria, Tunisia, Poland and Norwegian) were studied. Firstly T. urticae sequences obtained during this study were jointly analyzed with sequences of close species belonging to telarius group available in GenBank, including those of T. cinnabarinus Boisduval, a supposed synonym. Inconsistencies were detected during this investigation whose lead to make questions on the reliability of molecular data available in GenBank. About 30% of probable mistakes on the taxonomic identification were detected on sequences included in the analysis, especially to T. urticae, T. cinnabarinus, T. kanzawai Kishida… Advisors/Committee Members: Ivone Rezende Diniz, Carlos Holger Wenzel Flechtmann, Reinaldo José Fazzio Feres, Maria Navajas, Denise Navia Magalhães Ferreira, Rosana Tidon Franco.
