Survey of phytoseiid mites (Acari: Phytoseiidae) in orchards and surrounding vegetation of northwestern Europe, especially in the Netherlands. Keys, descriptions and figures

Abstract

Nine genera of phytoseiid mites with 22 species are described and illustrated on the basis of a survey of the literature, and by examination of material from orchards and their surroundings and of material from museum collections. Males, if available, are also described and figured.In addition to the species listed for the Netherlands, six species from around orchards in East Germany, Belgium and Poland were described briefly, and related species from other European countries (especially the British Isles and Germany) are noted.For each genus, a key to species (adult females) is given. For each species, a diagnosis is presented, and taxonomic problems are discussed for the following taxa: Phytoseius macropilis (Banks); Amblyseius reductus Wainstein; A. cucumeris (Oudemans); A. masseei (Nesbitt); A. potentillae (Garman); A. rademacheri Dosse; A. isuki Chant.Keys are based on easily recognizable features and are aimed at the 'interested non-taxonomist'.

Euseius gallicus Kreiter and Tixier (Acari: Phytoseiidae) is present in four more countries in Europe: Belgium, Germany, the Netherlands and Turkey

“…Only E. finlandicus was known in Belgium, Germany and The Netherlands (Miedema, 1987;Moraes et al 2004).…”

Phytoseiid mites on Quercus cerris in an urban park - short communication

“…acer spp., aesculus hippocastanum, Corylus avellana, Quercus sp., Syringa vulgaris, Tilia platyphyllos, Viburnum sp. (Chant & Yoshida-Shaul 1987;Miedema 1987;Papaioannou-Souliotis et al 2000;Duso et al 2004). Similarly to K. aberrans, T. (T.) pyri is a generalist predator that is commonly found on pubescent leaves (Roda et al 2003;McMurtry et al 2013).…”

“…A total of 1257 specimens of phytoseiids belonging to five species, Kampimodromus aberrans (Oudemans), Typhloseiulus peculiaris (Kolodochka), euseius finlandicus (Oudemans), Typhlodromus (Typhlodromus) pyri Scheuten, and Paraseiulus triporus (Chant & Yoshida-Shaul), were found on the undersurfaces of the surveyed oak leaves (Table 1). Six phytoseiid species were found on Q. cerris leaves (Kolodochka 1978;Miedema 1987;McMurtry & Croft 1997;Duso et al 2004;Ripka 2006;Kabíček 2008;McMurtry et al 2013). K. aberrans was regularly sampled on vines in productive vineyards (Tixier et al 2000), and it is a common and frequently observed phytoseiid species in apple and hazelnut orchards (Ozman-Sullivan 2006;Tixier et al 2014).…”

“…Immature phytoseiid stages were not determined and were excluded from the analyses. The phytoseiids were classified based on the Kolodochka (1980), Beglyarov (1981a, and Chant and YoshidaShaul (1982, 1983, 1987 keys. The nomenclature of the phytoseiid species used in this study follows Demite et al (2016).…”
