Öğe Determination of some wheat pests and their parasitoids in wheat fields of Central Anatolia Region(ENTOMOLOGICAL SOC TURKEY, EGE UNIV, 2010) Korkmaz, E. Mahir; Orgen, Sevda Hastaoglu; Gencer, Lutfiye; Ulgenturk, Selma; Basibuyuk, Hasan H.The study carried out between April 2001 and June 2003 in Central Anatolia Region aims to determine crop pests, their infestation rate and natural enemies in wheat fields Among the 16 species of stem sawflies (Cephini) found in wheat fields, Cephus pygmeus (Linnaeus, 1767) and Trachelus tabidus (Fabricius, 1775) are represented with largest population size respectively. Tetramesa tritici (Fitch, 1859), Tetramesa maderea (Walker, 1849) and Tetramesa nr. sp eximia (Giraud, 1863) are determined as gall producers in wheat stems. A total of nine parasitoid species were identified Of these Chlorocytus breviscapus Graham, 1965 Norbanus obscurus (Masi, 1922) and Collyria coxator (Villers, 1789) are parasitoids of wheat stem sawflies. Mensus splendidus Walker, 1834 and Eurytoma flavimana Boheman, 1836 are identified as parasitoids of gall wasps Pedrobius eubius (Walker) is noted as likely parasitoids of either stem sawflies or gall producers. Hosts of the three retaining parasitoids are not defined with confidence. Two parasitoid species, P eubius and C breviscapus are new records for Turkey. The results revealed that rate of wheat stem sawfly infested fields is very high (74 54%), but rate of infested stems is very low (2 78%) Parasitoids are found in 56 3% of the visited wheat fields. This result putatively suggests that the population size of the pest species are essentially controlled by their parasitoidsÖğe Fatty Acid Composition of Diplolepis fructuum (Rubsaamen, 1895) (Hymenoptera: Cynipidae) During Its Developmental Stages(GAZI ENTOMOLOGICAL RESEARCH SOC, 2017) Akpinar, Mehmet Ali; Gorgun, Salih; Gencer, Lutfiye; Aktumsek, AbdurrahmanIn this study, fatty acid composition in lipid classes of Diplolepis fructuum (Rubsaannen, 1895) (Hymenoptera: Cynipidae), an insect species inducing gall formation on the rose hips (the genus Rosa), during its various developmental stages was analyzed. According to the results obtained, C 16:0, C 18:0, C 18:1 n-9, C 18:2 n-6 and C 18:3 n-3 were the most abundant fatty acids in lipid classes during developmental stages. In D. fructuum, the presence of C 20 polyunsaturated fatty acids could not be determined. The most important finding for the fatty acid analyses of the galls and the healthy fruits of the rose hips was that polyunsaturated fatty acid (PUFA) levels were higher in the healthy fruits.Öğe Fatty acid composition of Gryllus campestris L. (Orthoptera: Gryllidae) during its various developmental stages(2003) Akpinar, M. Ali; Akpinar, Nukhet; Gencer, Lutfiye; Turkoglu, SifaThe fatty acid composition of Gryllus campestris was analyzed by gas chromatography at successive stages during development and including own eggs. Qualitative analysis revealed the presence of 14 fatty acids (carbon chain length from C12 through C20) in addition to unidentified fatty acids during all stages. There were no differences between fatty acid profiles of eggs, all nymphs, male and female adults. The major components of total fatty acid composition were C16:0, C18:0, C18:1, C18:2 and C18:3. These fatty acids were found to comprise 88-92% of the total fatty acids in all nymphs, male and female adults. The content of C16:0, C18:0, C18:1 and C18:3 decreased in eggs and emerged nymph in contrast; the content of C16:1, C18:2 and C20 fatty acids increased. Certain C20 polyunsaturated fatty acids (PUFA) (C20:2, C20:3 and C20:4) were detected in the nymphs and adults. Decreases were observed in the contents of total saturated and total polyunsaturated fatty acids, but total monosaturated fatty acid content showed an increase as from the first nymph stage of both sexes. It is suggested that the fatty acids C16:0, C18:1, C18 and C20 PUAFs are necessary for normal development of G. campestris during their life stages.Öğe Numerical taxonomy of Ormyrus Westwood, 1832 (Ormyridae: Hymenoptera) species based on general morphology in Sivas(ENTOMOLOGICAL SOC TURKEY, EGE UNIV, 2017) Aras, Funda; Gencer, LutfiyeThe main objectives of the study were to determine the adequacy and reliability of characters used for identification of Ormyrus (Ormyridae: Hymenoptera) species, and the relationships between species within the genus by numerical taxonomic analysis. The specimens studied were collected in Sivas Province in 2010. Individual females of five species in to Ormyrus were examined. One hundred morphological characters were measured for 249 specimens. Three different numeric taxonomic analyses were performed, principal component, principal coordinate, and cluster analyses, using computer package software PAST. Principal components and coordinate analyses revealed the with characters of sufficient value to reliability distinguish five species of Ormyrus. Examination of the relationship between the five species by clustering analysis showed that the species belonged to two different main groups. The robustness of the currently available identification keys and new characters that could be used for of species identification was also determined.Öğe Turkish Hybotidae (Diptera: Empidoidea): description of six new species with additional data(Magnolia Press, 2025) Zouhair, Laila; Grootaert, Patrick; Gencer, Lutfiye; Kettani, KawtarSix species belonging to the genera Platypalpus Macquart, Tachydromia Meigen and Drapetis Meigen are described as new for science from the Asian part of Turkey (Anatolia): P. sivasensis sp. nov., P. hirfanlicus sp. nov., P. latemoides sp. nov., P. durulmusensis sp. nov., T. sivasensis sp. nov. and D. incompletoides sp. nov. The species P. nigritarsis Fall & eacute;n is recorded herein for the first time from Turkey. We report for the first time the occurrence of Platypalpus bohousi Bart & aacute;k & Kubik, P. kirtlingensis Grootaert, P. longiseta Zetterstedt and Crossopalpus setiger Loew in previously unreported biogeographical areas within the country with detailed data on their distribution. All new species are described and illustrated.
