  • a new Euseius species on citrus and wild lime zanthoxylum fagara rutaceae in florida and an updated key to Euseius species from the state
    2020
    Co-Authors: Edward A Ueckermann, Gilberto J. De Moraes, Carl C Childers
    Abstract:

    A new Euseius Wainstein species, Euseius ennsi n. sp., is described from adult males and females collected from citrus and wild lime in an extensive survey conducted in 2009–2014 to evaluate the phytoseiid mites from citrus plants in dooryard, experimental and commercial plantations in Florida. An updated key is provided for the seven Euseius species reported so far from citrus in the state.

  • potential predation of the exotic amblyseius swirskii on Euseius concordis acari phytoseiidae a predatory mite commonly found in brazil
    2017
    Co-Authors: Ana Cristina Cerqueira Cavalcante, Nazer Famah Sourassou, Gilberto J. De Moraes
    Abstract:

    ABSTRACTIntra/interspecific predation by A. swirskii.Both Benin and Netherlands populations of Amblyseius swirskii engaged in cannibalism, and in predation on Euseius concordis larvae. Provision of pollen decreased cannibalism considerably, but had a smaller effect on predation on E. concordis. Potential effect of the eventual introduction of A. swirskii for control of Bemisia tabaci in Brazil is discussed.

  • definition of the concordis species group of the genus Euseius acari phytoseiidae with a morphological reassessment of the species included
    2015
    Co-Authors: Paula C Lopes, J. A. Mcmurtry, Gilberto J. De Moraes
    Abstract:

    Phytoseiidae (Acari) is the best known family of predatory mites. Within this family, Euseius Wainstein is one of the largest genera. The species of this genus have generalist feeding behavior, including in their diet mites and pollen. Some studies have demonstrated the potential of certain Euseius species to control pest mites. Euseius concordis (Chant) has been mentioned in the literature as potentially useful for the control of the tomato russet mite, Aculops lycopersici (Tryon) (Eriophyidae). Several other American species are morphologically similar to E. concordis; the morphological variation of these species is poorly understood. The objective of this study was a taxonomic re-evaluation of E. concordis and of the world species most similar to it. Measurements of species collected in this study and a taxonomic key to separate the species of this group are provided. Morphological evaluations confirmed that Euseius flechtmanni Denmark & Muma is a junior synonym of E. concordis, and determined that Euseius caseariae De Leon is also a junior synonym of E. concordis, that Euseius ho (De Leon) and Euseius brazilli (El-Banhawy) are junior synonyms of Euseius mesembrinus (Dean) and that Euseius vivax (Chant & Baker) is not a junior synonym of Euseius fructicolus (Gonzalez & Schuster), as previously thought.

  • Predadores do ácaro verde da mandioca no nordeste do Brasil
    2014

  • can Euseius alatus deleon acari phytoseiidae prey on aceria guerreronis keifer acari eriophyidae in coconut palm
    2009
    Co-Authors: Jose Wagner Da Silva Melo, Cleiton A Domingos, Manoel G C Gondim, Gilberto J. De Moraes
    Abstract:

    Mites of the genus Euseius are generally considered specialist as pollen feeders. Euseius alatus DeLeon is one of the six species of phytoseiid mites most commonly found on coconut plants in northeast Brazil associated with Aceria guerreronis Keifer. Although the morphology of E. alatus does not favor the exploitation of the meristematic area of the fruit inhabited by A. guerreronis, the predator may have some role in the control of this eriophyid during the dispersion process. The objective of this work was to evaluate the development and reproduction of E. alatus on the following diets: A. guerreronis, Ricinus communis pollen (Euphorbiaceae), and Tetranychus urticae Koch (Tetranychidae) + R. communis pollen + honey solution 10%. Euseius alatus developed slightly faster and had slightly higher oviposition rate when feeding on the diet composed of T. urticae + pollen + honey. However, life table parameters were very similar on all diets, suggesting that E. alatus may contribute in reducing the population of A. guerreronis in the field.

  • Phytoseiidae (Acari: Mesostigmata) on plants of the family Solanaceae: results of a survey in the south of France and a review of world biodiversity
    2020
    Co-Authors: Marie-stéphane Tixier, Martial Douin, Serge Kreiter
    Abstract:

    Species of the family Phytoseiidae are predators of pest mites and small insects. Their biodiversity is not equally known according to regions and supporting plants. This paper focuses on Phytoseiidae species on plants of the family Solanaceae. The Solanaceae contain many cultivated plants, for example tomato on which leaf characteristics hinder Phy-toseiidae settlement and dispersal. This study presents (i) results of surveys carried out on Solanaceae in the south of France, and (ii) Phytoseiidae biodiversity on Solanaceae worldwide. Eleven species were retrieved on 20 solanaceous plants in the south of France with four main species: Euseius gallicus, Euseius stipulatus, Phytoseiulus persimilis and Typhlodromus (Anthoseius) recki. The global analysis suggests that much more species might be found enhancing sampling efforts, whatever the biogeographic region considered. Five Phytoseiidae genera concentrate the highest number of reports and species [Ambly-seius, Neoseiulus, Euseius, Phytoseius and Typhlodromus (Anthoseius)]. These genera are not evolutionarily related; adaptation on Solanaceae seems to be recent, except in the Neotropical region. The latter region represents the highest number of reports, species and Solanaceae plants sampled, probably as the centre of origin of this plant family. Occurrence probabilities in biogeographic regions and plant genera are provided as a baseline for searching for new predators adapted to Solanaceae.

  • Predatory mites (Acari: Phytoseiidae) first recorded on cultivated plants in Slovenia in the period 2012-2017
    2018
    Co-Authors: T. Bohinc, Marie-stéphane Tixier, Serge Kreiter, G. Vierbergen, S. Trdan
    Abstract:

    In the period 2012-2017 we investigated the occurrence of indigenous species of predatory mites in different cultivated plants in Slovenia. In a comprehensive study we confirmed the occurrence of the following predatory mites: Amblyseius andersoni (Chant, 1957), Euseius finlandicus (Oudemans, 1915), Euseius gallicus (Kreiter & Tixier, 2010), Euseius stipulatus (Athias-Henriot, 1960), Kampimodromus abberans (Oudemans, 1930), Neoseiulus californicus (McGregor, 1954), Paraseiulus triporus (Chant & Shaul, 1982) and Phytoseius horridus (Ribaga, 1904). In the paper all seven species are presented, but for the field of biological control A. andersoni, E. gallicus and N. californicus are the most interesting species. The first two of them are already on the List of indigenous organisms for the purpose of biological control, while the third will be placed into it in the near future. All three of them have a great potential in biological control, since they can be found in different host plants

  • Integrative taxonomy approach for analysing evolutionary history of the tribe Euseiini Chant & McMurtry (Acari: Phytoseiidae)
    2017
    Co-Authors: Victor Santos, Victor Vicente Dos Santos, Marie-stéphane Tixier
    Abstract:

    Phylogenetic relationships within the mite Family Phytoseiidae are little known. The presently accepted classification is based on the opinion of specialists, but not on cladistics analysis. The present paper focuses on the tribe Euseiini, containing 271 species, three subtribes and 10 genera. It aims to determine phylogenetic relationships between these taxa and test their monophyly. Molecular analysis combining six markers has been carried out for taxa we succeeded in collecting. Morphological, biogeographic and ecological data have been analysed to determine how these factors can explain the evolutionary relationships emphasized on the phylogenetic tree. Those analyses have been carried out for the taxa available for the molecular study, but also for all species of the tribe. The tribe Euseiini and the two subtribes considered are monophyletic (at least considering the available taxa), supporting the present hypothesis on Phytoseiidae classification. However, the genus Iphiseius seems to not be valid and its unique species is included in the genus Euseius. Clades that were observed within the genus Euseius do not match with recent work on species groups within this genus. It seems that some morphological features such as an insemination apparatus shape and seta length on the dorsal shield constitute some elements explaining the clusters within the genus Euseius. Biogeographic and ecological data analysis led us to hypothesize a west Gondwanian origin of the tribe Euseiini (Africa and Neotropical areas) on Rosids plants (especially of the Orders Malpiphiales and Fabales: subclass Fabidae). Further analyses are still required to (i) take into account more taxa (especially rare ones and species from the Ethiopian part), (ii) to consider more accurate morphological features through more powerful microscopic apparatus, and (iii) to associate a phylogenetic and evolutionary scenario to life traits (pollen feeders).

  • A new species of the genus Euseius Wainstein (Acari: Phytoseiidae) from France
    2010
    Co-Authors: Marie-stéphane Tixier, Serge Kreiter, Mireille Okassa, Brigitte Cheval
    Abstract:

    The identity of specimens belonging to the genus Euseius found on several trees in France is investigated. Previous molecular and morphological analyses have shown that the new species herein described is different from Euseius stipulatus. Among the 187 species belonging to the genus Euseius, four of them (Euseius querci, Euseius amissibilis, Euseius kirghisicus and Euseius longiverticalis) seem to be morphologically close to this new species. However, none were very similar. This paper reports the description of this new species: Euseius gallicus sp. nov. Kreiter and Tixier

  • molecular and morphological evidence for a new species status within the genus Euseius acari phytoseiidae
    2009
    Co-Authors: Mireille Okassa, Marie-stéphane Tixier, Brigitte Cheval, Serge Kreiter
    Abstract:

    The identity of specimens belonging to the genus Euseius Wainstein, 1962 found on several trees in France is investigated. These specimens are morphologically close to Euseius stipulatus (Athias-Henriot, 1960) except for the shape of the spermatheca and the dorsal shield reticulation. The aim of the present study was to determine if these specimens belong to this latter species and if the shape of the spermatheca could be considered a reliable diagnostic character. Thirty-four characters, including idiosomal seta lengths, were measured and molecular tests (12S rDNA, COI mtDNA) were carried out. Although small, significant differences between populations of Euseius sp. were observed. The morphometric differences between E. stipulatus and Euseius sp. were very small except for the seta z2 and for the length of the ventrianal shield, as well as the length and form of the spermatheca. Molecular analyses support that Euseius sp. and E. stipulatus are two different species. Euseius sp. has been described as a n...
