Authors give a report on the recent results of mite collectings made mainly between 2003 and 2009 on ornamental trees and shrubs, on streets, in parks, in forests, in botanical gardens, private gardens and in orchards in various localities of Hungary. This survey also covers material collected in a winter barley and winter wheat field by Malaise-trap and from imported plant consignment. Representatives of 13 families were identified. Out of 31 mite species Arctoseius longispinosus (Hirschmann), Eutogenes frater Volgin, Hypoaspis mixta Shcherbak, Kampimodromus corylosus Kolodochka, Parasitus americanus (Berlese) and Proctolaelaps scolyti Evans are new for the Hungarian fauna.

Female, male and nymph of Aculops mosoniensis Ripka n. sp., collected from Ailanthus altissima are described and illustrated from Hungary. Taxonomically relevant morphological details are illustrated and the species is diagnosed from other tree-of-heaven inhabiting congeners.

Three specimens of invasive pest mite, Brevipalpus californicus (Banks, 1904) were collected on leaves of Dracaena marginata ʻTricolorʼ plant. The collected specimens belong to the Beard et al. (2015) “species B group” on the basis of the morphology of prodorsal and opisthonothal pattern. A new key to the Hungarian Brevipalpus is given.

Bariella bakonyense n. sp. and Glyptacus matrensis n. sp. were collected, described and illustrated from Quercus cerris and Quercus petraea , respectively. Both eriophyid mite species are leaf vagrant. Aceria cerrigemmarum was collected, redescribed and illustrated from Quercus cerris . This gall mite species causes bud proliferation and death of buds in several Hungarian forests. Two other eriophyid mite records are presented.

Authors made regular mite collectings between 1990 and 2010 on ornamental trees and shrubs, on streets, parks, in city greenery, forests, botanical gardens and private gardens, in various localities of Hungary. Belonging to 6 families, 16 species are reported. New mesostigmatid, prostigmatid and astigmatid mite records and hosts records are presented.

The authors give account of 5 new species, viz. Metalorryia armaghensis (Baker 1968), Neoapolorryia kristinae Momen and Lundqvist 1996, Lorryia zaheri (Baker 1968), Neoseiulus californicus (McGregor 1954) and Tenuipalpus pacificus Baker 1945, which have not been recorded so far in the Hungarian fauna.

Two new species of eriophyoid mite, Aceria bendeguzi n. sp., associated with Alcea rosea (Malvaceae) and Acaralox hungarorum n. sp. from Agrimonia eupatoria (Rosaceae), are described and illustrated from Hungary. Morphological differences distinguishing these species from other malvaceous and rosaceous inhabiting congeners are discussed.

Authors made regular insect collections between 2010 and 2017, especially on ornamental trees and shrubs, on streets, parks, in city greenery, forests, botanical gardens and private gardens, in various localities of Hungary. Trioza soniae Rapisarda, 1994 and Trioza scottii Löw, 1880 are reported for the first time in Hungary. New host, locality and habitat data are given.

Authors give a report on the results of the regular collections made between 1990 and 1998 on ornamental trees and shrubs,on streets,in parks,in green spaces of housing estates,in private gardens and in arboreta.A total of 19 corticolous mite species were found belonging to 14 families.Michaelopus corticalis (Michael,1885),Hericia hericia Robin,1868,Eupalopsis maseriensis (Canestrini et Fanzago, 1876),Mediolata vandergeesti (Gomaa et Bolland,1982),Cunaxoides kielczewskii Michocka,1982,and Neophyllobius spec.nov.are reported for the first time for the Hungarian fauna.Hemisarcoptes budensis Fain et Ripka,1998,M.corticalis and Cheletogenes ornatus (Canestrini et Fanzago,1876)were the most frequent species in the acarofauna associated with scale insects.
