Öğe Ant (Hymenoptera: Formicidae) - aphid (Hemiptera: Aphididae) interactions in different habitats from Turkey with new mutualistic associations(Wiley, 2022) Kok, Sahin; Aktac, Nihat; Kasap, IsmailThis study aimed to investigate the interactions between ants and aphids on host plants in different habitats located in the northwestern part of Turkey. A total of 26 ant species belonging to 13 genera and 3 subfamilies from the family Formicidae (Hymenoptera) were found associated with 52 aphid species belonging to 22 genera from the family Aphididae (Hemiptera: Aphidoidea) on 66 host plant species from 24 plant families. In total, 132 tritrophic ants-aphids-host plants interactions including new associations were revealed. Also, we present results on the interactions of ants-aphids-host plants in different habitats such as cultivated, uncultivated and urban areas. About 85 tritrophic interactions of ants-aphids-host plants were revealed in cultivated, 27 tritrophic interactions in uncultivated and 20 tritrophic interactions in urban areas. Tritrophic interactions were more diverse in cultivated areas than uncultivated and urban areas. Our results reveal that the interactions between ants and aphids are highly diverse and that they vary on host plants in different habitats. It may be thought that this is due to the specialization resulting from the high diversity of host plants of aphids in cultivated areas and increased the presence of ants.Öğe Ants of the genus Camponotus Mayr, 1861 (Hymenoptera: Formicidae) in the Kaz Mountains, Turkey, with descriptions of sexuals of Camponotus candiotes Emery, 1894 and Camponotus ionius Emery, 1920(Tubitak Scientific & Technological Research Council Turkey, 2011) Karaman, Celal; Aktac, Nihat; Kiran, KadriThe Camponotus fauna of the Kaz Mountains was examined horizontally and vertically, from 175 to 1600 m a.s.l. Materials were collected from 20 different localities and 11 different habitats between 2001 and 2003. In all, 14 species belonging to 3 subgenera (Colobopsis Mayr, Myrmentoma Ford, and Tanaemyrmex Ashmead) were found. The hitherto unknown sexuals of C. candiotes Emery and C. ionius Emery are described for the first time.Öğe Contribution to the knowledge of Odonata fauna of Southern Marmara Region of Turkey(Entomological Soc Turkey, Ege Univ, 2009) Hacet, Nurten; Aktac, NihatRecords of 17 species and subspecies, collected in 1996, 2002 and 2003 from the Canakkale and Yalova provinces situated in the Southern Marmara Region of Turkey were listed. Of these, Libellula fulva Muller (Odonata: Libellulidae) is the first record for the region. New species for the Canakkale and Yalova provinces recorded in the present study were added to the species lists of these provinces. In addition, the distributions of some species, which are unclear in the region, were discussed.Öğe Contributions to the fauna of Acanthosomatidae, Thyreocoridae, Cydnidae, Plataspidae, Scutelleridae (Pentatomoidea: Heteroptera) from Turkish Thrace(Entomological Soc Turkey, Ege Univ, 2009) Fent, Meral; Aktac, NihatThis study was carried in 100 localities in five provinces of the Turkish Thrace, between the years 1992 and 2003. A total of 21 species belong to 13 genera from the five families (Acanthosomatidae, Thyreocoridae, Cydnidae, Plataspidae and Scutelleridae) of Pentatomoidea were determined.Öğe Descriptions of Four New Species of Camponotus Mayr (Hymenoptera: Formicidae), with a Key for the Worker Caste of the Camponotus of Turkey(Kansas Entomological Soc, 2013) Karaman, Celal; Aktac, NihatFour new species of Camponotus are described in Turkey: C. (Myrmentoma) aktaci C. Karaman new species, C. (Myrmentoma) anatolicus new species, C. (Myrmentoma) hirtus new species, and C. (Myrmentoma) honaziensis new species. In addition, two species, C. (Myrmentoma) abrahami Forel, 1913 and C (Tanaemyrmex) oasium Forel, 1890 are reported for the first time from Turkey. We reexamined the C. fedtschenkoi material collected in Eastern Anatolia and identified the material as similar to C. buddhae. Therefore, C. fedtschenkoi is a dubious record for Turkish ant fauna. An identification key for all known Turkish species of Camponotus is presented.Öğe Determined Aphid and Ant Associations from Trabzon, Rize and Artvin Provinces of the Turkey(Gazi Entomological Research Soc, 2014) Akyildirim, Hayal; Senol, Ozhan; Gorur, Gazi; Aktac, Nihat; Demirtas, EminAphids and ant species are both diverse and extremely succesful groups of insects and often share the same habitats and therefore both have many oportunities to interact with each other. It has been shown that aphid-ant relationships have been shaped by various factors particularly aphid host plant's physological features, honeydew composition, feeding position and so on. Despite there are more than 500 aphid species and about 315 ant taxon in Turkey, there are very few studies conducted on their mutual relationship. This study was carried out in the Trabzon, Rize and Artvin provinces of Turkey. As a result of the evaluation of samples, it was determined that 48 aphid species associated with 15 ant species. The most encountered ant species, which interacted with different number of aphid species, were Formica cinereofusca Karawaiew, 1929, Lasius turcicus Santschi, 1921 and Lasius emarginatus (Olivier, 1792). Among determined aphid species Aphis fabae Scopoli, 1763 had the highest ant attraction and then Brachycaudus cardui (Linnaeus, 1758), Aphis gossypii Glover, 1877, Aphis spiraecola Patch, 1914, Cinara pilicornis (Hartig, 1841) and Toxoptera aurantii Boyer de Fonscolombe, 1841 respectively. Determined aphid-ant associations are shaped by both ecological conditions of the study area, composition of aphid and ant populations and it was shown that there is no new aphid-ant species association. Findings of the presented study indicated that much more detailed study should be conducted to investigate aphid-ant mutualistic associations in Turkey.Öğe Heteroceran fauna of Gokceada and Bozcaada (North Aegean Islands, Turkey), with a new record of noctuidae (Lepidoptera), and biogeographical analyses(Amer Entomol Soc, 2007) Okyar, Zuhal; Aktac, NihatDuring 1988-1989, 72 species of heterocerans (Lepidoptera) were collected and identified in Gokceada and Bozcaada islands. One species collected on Gokceada Caradrina ingrata (Staudinger, 1897), is the first record for Turkey and the North Aegean Islands. All identified species are first records for Gokc eada and Bozcaada, whereas 32 of them are first records of heterocerans for the North Aegean Islands.Öğe New records of Pentatomoidea (Heteroptera) for the fauna of Europe, Turkey, and the Turkish Thrace(Amer Entomol Soc, 2007) Fent, Meral; Aktac, NihatThis study was carried out in various localities in five provinces of the Turkish Thrace, between the years 1992 and 2003. A total of 101 species from six heteropteran families (Pentatomidae, Scutelleridae, Thyreocoridae, Cydnidae, Acanthosomatidae and Plataspidae) were determined, 22 of the species are new records of the Pentatomoidea for the Turkish Thrace. Of these, three species (Thyreocoris fulvipennis, Neottiglossa lineolata, Podops inuncta) are first records for Turkey. It seems that Podops is a new genus record for Turkey. Picromerus brachypterus, which has previously been recorded from Anatolia (Turkey), is considered a new record for Europe.Öğe The odonata of Gokceada Island, Turkey(Amer Entomol Soc, 2006) Hacet, Nurten; Aktac, NihatThis study was conducted in the years 1998, 1999 and 2003, and it is the first one on the Odonata fauna found in Gokqeada Island (northern Aegean Sea, Turkey). During the study period, 29 taxa were collected, or observed, and identified. One of the species observed on Gokceada Island, Lindenia tetraphylla, is also found on the mainland of Turkey (Anatolian Peninsula, but only in five areas, Koycegiz, Marmaris, Adraman, Sanhurfa and N of Hatay). As far as Aegean islands are concerned L. tetraphylla is found only in Island Thassos. Onychogomphus forcipatus albotibialis and Pantala flavescens, whose distribution range in the Aegean Islands is unclear, are other zoogeographically noteworthy records. Biogeographical data is congruent with island biogeography theory (Mac Arthur and Wilson, 2001).Öğe The Parasitoid Complex of White-spotted Pinion Cosmia diffinis (Linnaeus, 1767) (Lepidoptera: Noctuidae) on Ulmus minor Miller (Ulmaceae) in Edirne Province (European Turkey)(Kansas Entomological Soc, 2012) Okyar, Zuhal; Yurtcan, Murat; Beyarslan, Ahmet; Aktac, NihatThe parasitoid complex of white-spotted pinion Cosmia diffinis (Linnaeus, 1767) larvae (Lepidoptera: Noctuidae) feeding on Ulmus minor in Edirne was studied during the two-year period of 2007-2008. The determined parasitoids were Meteorus colon (Haliday, 1835) and Meteorus rufus (DeGeer, 1778) from Braconidae; Gelis areator (Panzer, 1804), Itoplectis clavicornis (Thomson, 1889) and Phobocampe lymantriae Gupta, 1983 from Ichneumonidae; Brachymeria secundaria (Ruschka, 1922) from Chalcididae; Euplectrus liparidis Ferriere, 1941 from Eulophidae and members of Tachinidae. We report here a new host-parasitoid relationship of C diffinis with M. colon, M. rufus, I. clavicornis, P. lymantriae, and E. liparidis. The hyperparasitism of G. areator and B. secundaria on parasitoid Meteorus species of Cosmia diffinis is also reported. In addition, M. colon, I. clavicornis, G. areator, P. lymantriae and E. liparidis were determined as new records for Turkey.Öğe Some aspects of the moth (Lepidoptera, Heterocera) species diversity in Western Black Sea Region of Turkey(Univ Oradea Publ House, 2009) Okyar, Zuhal; Yurtsever, Selcuk; Aktac, Nihat; Cakan, GoekhanThe moth species were investigated in the four distinct types of habitat coniferous, beech, oak forests and shrubs including 57 different sites - of Western Black Sea Region in Turkey between the years of 2001 and 2004. A total of 207 Lepidoptera species belonging to 164 genera and 11 families was determined. Results showed that the index of diversity in the coniferous habitats (H=0.5592) was significantly higher than those of beech (H=0.3561) and oak forests (H=0.4238), but was not significantly different than those of shrubs (H=0.4921). The pooled species numbers of the coniferous habitats were the highest among the four types of habitat (P < 0.001). Moreover, the pooled number of species in the Noctuidae and Geometridae families were significantly higher (P < 0.001) than those found in the other Lepidoptera families in the study area. The pooled numbers of the species tended to decrease from June to September during the study months.Öğe Three new species of ants (genus Aphaenogaster, Hymenoptera: Formicidae) from Turkey(Versita, 2008) Kiran, Kadri; Aktac, Nihat; Tezcan, SerdarThree new species of the ant genus Aphaenogaster (A. aktaci sp. n., A. maculifrons sp. n., A. radchenkoi sp. n.) are described from Turkey and their taxonomic positions are discussed. Aphaenogaster aktaci sp. n. belongs to the obsidiana group, A. maculifrons sp. n. to subterranea group and A. radchenkoi sp. n. to pallida group of the Attomyrma subgenus. Key characteristics for identification of the species and data on their ecology are given.Öğe Two new records of Odonata (Gomphidae) for Turkey, Gomphus flavipes (Charpentier, 1825) and Ophiogomphus cecilia (Geoffroy in Fourcroy, 1785), with distributional notes on G. flavipes and G. ubadschii Schmidt, 1953(Amer Entomol Soc, 2008) Hacet, Nurten; Aktac, NihatIn this paper, we demonstrate the occurrence of Gomphus flavipes in Turkey. The single European Turkish record of this taxon was until now confused with the closely related Asiatic species Gomphus ubadschii, therefore it could be said that G. flavipes is new to Turkey. The distribution of the two species in Turkey is evaluated. Besides, Ophiogomphus cecilia, a species which was previously reported from Anatolia based on a misidentification, now for the first time is recorded for Turkey, in the Turkish Thrace.
