  • Fungicide reduction favors the control of Phytophagous Mites under both organic and conventional viticulture
    Agriculture Ecosystems & Environment, 2021
    Co-Authors: Jo Marie Reiff, Marvin Ehringer, Christoph Hoffmann, Martin H. Entling
    Abstract:

    Abstract Pesticides can have detrimental effects on non-target biodiversity, especially in intensively managed agroecosystems such as vineyards. However, new fungus-resistant grape varieties can greatly reduce the need and use of fungicides. Fungicides can have direct and indirect effects on economically important predatory Mites (mainly Phytoseiidae) and on Phytophagous Mites (Tetranychidae, Eriophyidae) on which they prey. We investigated the impact of fungicide treatments on beneficial and Phytophagous mite densities in 32 vineyards of organic and conventional wineries planted with susceptible and fungus-resistant grape varieties in the Palatinate region, Germany. Organic vineyards were sprayed with different formulations of sulfur, copper and potassium bicarbonate, while conventional vineyards received mostly synthetic fungicides. Fungicide applications were reduced by 47-80 % in fungus-resistant varieties, with stronger reductions under organic than under conventional management. Regardless of organic or conventional management, predatory Mites (Phytoseiidae and Tydeidae) were significantly enhanced in vineyards planted with fungus-resistant varieties. Contrastingly, Phytophagous Mites (Eriophyidae) were enhanced in vineyards with fungus-susceptible varieties and in those under organic management. Densities of further predatory mite families increased under organic farming (Anystidae) or showed an interactive response to farming system and grape variety (Trombidiidae). Reduced fungicide applications through cultivation of fungus-resistant varieties enhance predatory mite densities and thus contribute to higher natural pest control potential. Thus, the cultivation of fungus-resistant grape varieties is an effective approach towards more environmentally friendly viticulture.

  • Change in abundance of three Phytophagous mite species (Acari: Eriophyidae, Tetranychidae) on quackgrass in the presence of choke disease
    Experimental and Applied Acarology, 2016
    Co-Authors: Brian G. Rector, Marcin Czarnoleski, Anna Skoracka, Marlena Lembicz
    Abstract:

    Phytophagous Mites and endophytic fungi may interact when sharing a host plant, potentially influencing one another’s growth or population dynamics; however, interactions between them are poorly known and remain largely unexplored. In this study, quantitative associations between three species of Phytophagous Mites and the endophytic fungus Epichloë bromicola Leuchtm. & Schardl (Clavicipitaceae, Ascomycotina) on quackgrass, Elymus repens (L.) Gould are reported. The Mites’ abundance was assessed on field-collected grass shoots that were either exhibiting choke disease symptoms or without the fungus. Overall, the abundance of Tetranychus urticae and Aculodes mckenziei was significantly lower on quackgrass plants infected by E. bromicola compared to plants without the fungus. Conversely, populations of Abacarus hystrix were significantly larger on plants colonised by the fungus than on uninfected plants. Thus, the presence of this endophytic fungus may have divergent effects on different Phytophagous mite species although the basis of these effects is not yet known.

  • Editorial: Plant Responses to Phytophagous Mites/Thrips and Search for Resistance
    Frontiers in plant science, 2019
    Co-Authors: Raul Antonio Sperotto, Vojislava Grbic, Maria L. Pappas, Kirsten A. Leiss, Merijn R. Kant, Calum R. Wilson, M. Estrella Santamaria, Yulin Gao
    Abstract:

    Phytophagous Mites and thrips are global pests affecting a wide range of agricultural crops (Mouden et al., 2017; Agut et al., 2018). Among the arthropods, they are phylogenetically distant, but both classes harbor species ranging from highly specialized to extremely polyphagous (Rioja et al., 2017; Wu et al., 2018). Through convergent evolution, Mites and thrips evolved stylets to facilitate feeding from mesophyll or epidermal cells (Bensoussan et al., 2016; Rioja et al., 2017; Wu et al., 2018). Despite large crops losses (Agut et al., 2018; Steenbergen et al., 2018) that are expected to become more severe with global warming (Ximenez-Embun et al., 2017; Urbaneja-Bernat et al., 2019), the interactions between Mites/thrips and their host plants have been understudied. Hence, understanding how plants defend themselves against these pests is essential for developing crop protection strategies. This Research Topic provides an update on recent advances in the plant molecular and physiological mechanisms associated with Phytophagous mite/thrips-plant interactions, and provides an overview of different approaches for improving crop resistance sustainably, either through repellence, feeding disruption or prevention of feeding damage. Here, we highlight some of the major points arising from these reports.

  • Phytophagous Mites (Acari: Eriophyoidea) recorded from Svalbard, including the description of a new species
    Polar Biology, 2016
    Co-Authors: Agnieszka Kiedrowicz, Brian G. Rector, Krzysztof Zawierucha, Wiktoria Szydło, Anna Skoracka
    Abstract:

    Eriophyoid Mites (Eriophyoidea) are minute Phytophagous Mites with great economic importance and great invasive potential. In spite of their demonstrated impact on ecosystem functions, knowledge of eriophyoid mite fauna in the Arctic is lacking. To date, only eight eriophyoid mite species have been recorded from the entire region north of the Arctic Circle. The Svalbard archipelago is one of the most biologically investigated Arctic areas. Despite the fact that studies on invertebrates on Svalbard have been conducted for more than one hundred years, eriophyoids have never been recorded before from this place, except for one likely accidental record of a single specimen belonging to the genus Eriophyes . Thus, each new study of eriophyoid mite fauna in this region is important. In this paper, a new species of eriophyoid mite, Cecidophyes siedleckii n. sp., is described and illustrated. Nucleotide sequence data (D2 region of 28S rDNA) were employed to complement traditional morphological taxonomy. The first record of Aceria saxifragae (Rostrup 1900 ) from Svalbard is also provided, with supplementary morphological descriptions and illustrations. Eriophyoid Mites represent an important and underutilized taxon that is available to ecologists studying the effects of changing climatic conditions on Svalbard.
