    (Entomological Soc Turkey, Ege Univ, 2019) Cakmak, Taylan; Gozel, Cigdem; Kaydan, M. Bora; Gozel, Ugur
    In this study, plant parasitic nematode fauna from Mount Ararat was determined according to altitude. A total of 30 soil samples were taken in 2013 during summer. Nematodes were extracted by a modified Baermann funnel technique. Nematodes were identified by morphology, morphometric and phylogenetic analysis based on sequences of the D2-D3 and ITS1-rRNA gene sequences. Permanent slides of individuals were made and species-specific characters were screened by scanning electron microscopy (SEM). SEM studies were processed at the Department of Animal Biology, Vegetal Biology and Ecology, SEM laboratory University of Jaen in Spain during 2014. A total of 19 plant parasitic nematodes were identified from Mount Ararat. Three plant parasitic nematodes Rotylenchus conicaudatus Atighi et al., 2011 (Nematoda: Hoplolaimidae), Heterodera trifolii Goffart, 1932 (Nematoda: Heteroderidae) and Tylenchorhynchus mangiferae (Luqman & Khan, 1986) (Nematoda: Belonolaimidae) from this study are new records for plant parasitic nematode fauna of the Turkish.

    (Entomological Soc Turkey, Ege Univ, 2011) Atlihan, Remzi; Ozgokce, M. Salih; Kaydan, M. Bora; Kasap, Ismail; Kilincer, Neset; Kiyak, Suat; Polat, Evin
    This study was carried out to determine insect pests and their natural enemies in walnut orchards in Van lake basin in 2005-2006. Steiner funnel, visual observation and rearing method were used for samplings. As a result, 29 phytophagous species belonging to 11 different families and 21 beneficial insect species belonging to 6 families were determined. It was observed that Cydia pomonella (L., 1758) (Lepidoptera: Tortricidae) was the economically important pest, and Panaphis juglandis (Goeze, 1778) (Hemiptera: Callaphididae) had remarkable population level. Chrysoperla carnea (Stephens, 1836) (Neuroptera: Chrysopidae) and Adalia fasciatopuncata revelierei (Mulsant, 1866) (Coleoptera: Coccinellidae) were the most common and widely distributed species among natural enemies obtained.

    New records of free-living nematode species from Mount Ararat, Turkey, with SEM study of three remarkable species
    (Springer, 2021) Çakmak, Taylan; Kaydan, M. Bora; Gözel, Çiğdem; Peña-Santiago, Reyes; Abolafia, Joaquín; Gözel, Uğur
    This paper presents a study of free-living nematodes (excepting Dorylaimida) from Mount Ararat, Turkey. A total of 25 species are recorded, which belong to the orders Enoplida (one species), Triplonchida (2), Chromadorida (1), Monhysterida (2), Plectida (4) and Rhabditida (18). Nine of them are new for the Turkish fauna: Acrobeles andalusicus, A. ciliatus, Acrolobus longigubernaculum, Cervidellus vexilliger, Chiloplacus trilineatus, C. bisexualis, Panagrolaimus rigidus, Propanagrolaimus hygrophilus, and Teratocephalus terrestris. Three species, namely A. longigubernaculum, C. vexilliger and T. auriculatus, are re-described, including morphological and morphometrical data, and SEM study. The altitudinal distribution of the species is also provided.

    Population density of the important harmful mites and their predatories in the walnut orchards of around Van Lake
    (Entomological Soc Turkey, Ege Univ, 2009) Kasap, Ismail; Atlihan, Remzi; Ozgokce, M. Salih; Kaydan, M. Bora; Polat, Evin; Yarimbatman, Alper
    The aim of this study was to determine the population densities of pest and important predatory mites in the walnut orchards of around Van Lake. The study was conducted in five walnut orchards in the Adilcevaz county in Bitlis (three orchards) and Gevas county in Van (two orchards), during the growing seasons of 2005-2006. Surveys were carried out in every week from May to November. The results of study indicated that the population densities of mites began to increase generally in early July, reached the maximum level at late July and at early August and preserved to late October. In this period, the population densities of Aceria erinea Nalepa (Acari: Eriophyidae) and Eotetranychus carpini (Oudemans) (Acari: Tetranychidae) were determined as 51.9 galls/leaf and 304.1 mites/leaf, respectively. Euseius finlandicus (Oudemans) (Acari: Phytoseiidae) was the most effective predatory mite on E. carpini and A. erinea and it was observed that its population reached to 4.5 mites/leaf. In the sprayed orchard, E. finlandicus population was not enough for controlling mites and the population densities remained at very low levels.
