This study was conducted to determine mite species and their population densities onsummer and winter vegetables grown on the Bafra and Carsamba plains in SamsunProvince, Turkey in 2015 and 2016. A total of 480 samples were collected from 74sampling sites in open fields in 7 districts. Forty two percent (42%) of the sampleswere infested by mites. A total of thirty seven species belonging to eleven familieswere collected. They were Tyrophagus putrescentiae (Schrank) (Acaridae);Czenspinskia transversostriata (Oudemans) (Winterschmidtiidae); Aculopslycopersici Massee (Eriophyidae); Tetranychus urticae Koch, Tetranychus turkestaniUgarov and Nikolskii, Tetranychus sp., Panonychus ulmi (Koch), Bryobia sp. 1,Bryobia sp. 2 (Tetranychidae); Brevipalpus obovatus Donnadieu (Tenuipalpidae);Tarsonemus confusus Ewing, Tarsonemus lobosus Suski, Tarsonemus smithi Ewing,Tarsonemus waitei Banks, Polyphagotarsonemus latus (Banks) (Tarsonemidae);Tydeus californicus (Banks), Tydeus caudatus (Dugés), Tydeus kochi Oudemans,Tydeus martae Kazmierski, Tydeus praeditus Livshitz et Zapletina, Lorryia pulchra(Oudemans), Lorryia rutrus Theron et Ueckermann, Lorryia visenda (Kuznetzov)(Tydeidae); Homeopronematus staerki (Schruft) (Iolinidae); Allothrombium clavatumSaboori, Pesic, Hakimitabar, Allothrombium fuliginosum (Hermann) (Trombidiidae);Dometorina plantivaga plantivaga (Berlese) (Oribatulidae); Amblyseius andersoni(Chant), Amblyseius rademacheri Dosse, Euseius finlandicus (Oudemans), Euseiusstipulatus (Athias-Henriot), Neoseiulus aristotelisi Papadoulis, Neoseiulus barkeriHughes, Neoseiulus californicus (McGregor), Neoseiulus marginatus (Wainstein),Phytoseius finitimus Ribaga, Phytoseiulus persimilis Athias-Henriot (Phytoseiidae).Eight species Tarsonemus smithi, T. martae, T. praeditus, L. rutrus, L. visenda, A.clavatum, D. plantivaga plantivaga and N. aristotelisi were first records for Turkey.Key Words: Çarşamba Plain, Bafra Plain, Samsun, summer vegetable, wintervegetable, harmful mite, beneficial mite.

Bu çalışma 2015 ve 2016 yıllarında Bafra ve Çarşamba ovalarında yetiştirilen yazlıkve kışlık sebze çeşitlerinde bulunan akar türleri ve populasyon yoğunluklarınınbelirlenmesi amacıyla yürütülmüştür. Bu amaçla Samsun iline bağlı 7 ilçedeki 74yerden örnekleme yapılmış ve 480 adet örnek toplanmıştır. İncelenen örneklerin%42'si akarlarla bulaşık olarak bulunmuş ve 11 familyaya ait 37 akar türü tespitedilmiştir. Bu türler; Tyrophagus putrescentiae (Schrank) (Acaridae); Czenspinskiatransversostriata (Oudemans) (Winterschmidtiidae); Aculops lycopersici Massee(Eriophyidae); Tetranychus urticae Koch, Tetranychus turkestani Ugarov andNikolskii, Tetranychus sp., Panonychus ulmi (Koch), Bryobia sp. 1, Bryobia sp. 2(Tetranychidae); Brevipalpus obovatus Donnadieu (Tenuipalpidae); Tarsonemusconfusus Ewing, Tarsonemus lobosus Suski, Tarsonemus smithi Ewing, Tarsonemuswaitei Banks, Polyphagotarsonemus latus (Banks) (Tarsonemidae); Tydeuscalifornicus (Banks), Tydeus caudatus (Dugés), Tydeus kochi Oudemans, Tydeusmartae Kazmierski, Tydeus praeditus Livshitz et Zapletina, Lorryia pulchra(Oudemans), Lorryia rutrus Theron et Ueckermann, Lorryia visenda (Kuznetzov)(Tydeidae); Homeopronematus staerki (Schruft) (Iolinidae); Allothrombium clavatumSaboori, Pesic, Hakimitabar, Allothrombium fuliginosum (Hermann) (Trombidiidae);Dometorina plantivaga plantivaga (Berlese) (Oribatulidae); Amblyseius andersoni(Chant), Amblyseius rademacheri Dosse, Euseius finlandicus (Oudemans), Euseiusstipulatus (Athias-Henriot), Neoseiulus aristotelisi Papadoulis, Neoseiulus barkeriHughes, Neoseiulus californicus (McGregor), Neoseiulus marginatus (Wainstein),Phytoseius finitimus Ribaga, Phytoseiulus persimilis Athias-Henriot(Phytoseiidae)'dir. Bunlardan sekiz tür; Tarsonemus smithi, T. martae, T. praeditus, L.rutrus, L. visenda, A. clavatum, D. plantivaga plantivaga ve N. aristotelisi türleriülkemiz faunası için yeni kayıt olarak tespit edilmiştir.Anahtar Kelimeler: Çarşamba Ovası, Bafra Ovası, Samsun, yazlık sebze, kışlıksebze, zararlı akar, faydalı akar.
