Eriophyoid Mite Fauna (Acari: Trombidiformes: Eriophyoidea) of Turkey: New Species, New Distribution Reports and an Updated Catalogue
(Magnolia Press, 2015) Denizhan, Evsel; Monfreda, Rosita; De Lillo, Enrico; Cobanoglu, Sultan
More than one hundred species of Eriophyoidea have been recorded hitherto from Turkey. Within the last decade, a large plant survey was carried out in order to investigate the eriophyoid fauna present in Turkey, with particular emphasis on species affecting weeds and ornamental plants. In addition, the Turkish literature has been examined for previous records of eriophyoid mites. New species, Paraphytoptus intybi n. sp. on common cichory, Cichorium intybus (Compositae) and Phytoptus albae n. sp. on white poplar, Populus alba (Salicaceae), are described and illustrated herein. In addition, a further 31 species were found to be new records for the eriophyoid fauna of Turkey with Aceria calaceris, Phyllocoptes didelphis and Vasates immigrans being new reports for the Palaearctic region. All known eriophyoid species records from Turkey appearing in papers published up until March 2013 are listed in this catalogue along with remarks and information on their current distribution in Turkey and taxonomic status.
Eriophyoid Mites (Acari: Prostigmata: Eriophyoidea) in Van Lake Basin From Turkey
(Taylor & Francis inc, 2010) Denizhan, Evsel; Cobanoglu, Sultan
There has been no study on the fauna of Eriophyoidea in the Van Lake Basin in the eastern part of Anatolia. A survey was carried out to determine the Eriophyoidea on the natural and cultured plants of the Van Lake Basin during 2007-2008. Twenty-five species were found, two of which (Eriophyes euphorbiae; Abacarus hystrix) are new records for the Turkish eriophyoid fauna.
Eriophyoid Mites (Acari: Prostigmata: Eriophyoidea) on Ulmus Campestris L. (Ulmaceae) in Van Lake Basin
(Entomological Soc Turkey, Ege Univ, 2010) Denizhan, Evsel; Cobanoglu, Sultan
Eriophyoid mites (Acari: Prostigmata: Eriophyoidea) on Ulmus campestris L. (Ulmaceae) in Van Lake basin This paper provides information about Eriophyoidea fauna on Ulmus campestris L. (Ulmaceae) of Van Lake basin during 2007-2009 years. As a result 4 species were identified; Aceria filiformis (Nalepa, 1891), Aceria campestricola (Frauenfeld, 1865), Tetra concava (Keifer, 1939) and Shevtchenkella ulmi (Farkas, 1960) (Acarina: Eriophyidae). S. ulmi is a new record for the fauna of Turkey.
One Example of Using Geographic Information Systems Studies in the Field in Acarology: Google Earth
(Taylor & Francis inc, 2010) Denizhan, Evsel; Cobanoglu, Sultan; Kotaoglu, Caglar
Geographic information systems are geographical position-based and analysis and information-sharing systems that can be used for all scientific studies. GOOGLE EARTH software provides cartographical map information and satellite images to all internet users and shows the smallest settlement units of countries and cities. Researchers can also access map information quickly and are able to locate their geographical position. We used this system during a study of the determination of Eriophyoidea (Acarina) species, their hosts, distribution, natural enemies, and population development of Aculus schlechtendali (Nalepa, 1892) on ornamental plants in Ankara.
Population Development and Predators of Aculus Schlechtendali (Nalepa) (Acarina: Eriophyidae) on Malus Floribunda L. (Rosaceae) in Ankara
(Ankara Univ, Fac Agr, 2008) Denizhan, Evsel; Cobanoglu, Sultan
Population development of Aculus schlechtendali (Nalepa) (Acarina: Eriophyidae) was investigated in three different locations (Kecioren, Besevler and Kalaba) in Ankara, on Malus floribunda L. (Rosasacae) during 2004 - 2006 years. Two-year of observations revealed that A. schlechtendali individuals were hibernates in deutogyne stage in the crevices and hiden places of the trees. They began to move to the blossoms of the plants at the beginning of may. Deutogynes laid their eggs on the feeding place of the youngs. In general higher eriophyoid protogyne populations were observed during May and June all three locations of the study area. The data show that the deutogyne population reached its peak by the end of May and after this, the deutogyne population levels become lower whereas protogyne population showed small rate of increas around the same time but reached its peak by mid June. Deutogyne population has been seen in low population density during the summer months. During surveys on predators of Aculus schlechtendali two phytoseiids, one stigmaeid, and one tydeid mite species, and 14 Cocinellidae species were recognized as natural enemies. Beside this, taxonomic characteristics and distribution of this eriophyid species were indicated.
