The list is based on a detailed study of all available published data. Nine vespine species from three genera (Vespa Linnaeus, Vespula Thomson, Dolichovespula Rohwer) are currently recognized as occurring in Iran.Öğe A Study on Karyotypes of Two Species of Anoplius (Hymenoptera: Pompilidae) in Kars Plateau, Turkey(KAFKAS UNIV, VETERINER FAKULTESI DERGISI, 2009) Kirpik, M. Ali; Guel, Sueleyman; Nur, Goekhan; Inak, Sedat; Cilingir, Murat; Aldemir, Adnan; Bagriacik, NilIn this study. karyotypes of two Pompilidae species [Anoplius viaticus (Linnaeus 1758) and Anoplius concinnus (Dahlbom 1845)] were studied. Based on metaphase studies, it was determined that Anoplius viaticus has 2n=28 chromosomes and that their karyotypes consisted of 3 metacentric. 2 submetacentric and 9 acrocentric chromosome pairs, and the fundamental number (NF) was 38. Metaphase studies of Anoplius concinnus gave the result that it had 2n=28 chromosomes. of which karyotype consisted of 2 metacentric, 4 submetacentric and 8 acrocentric chromosome pairs, and the NF was 40. No heteromorphic sex chromosomes for each species were foundÖğe COMPARISON OF CHITIN STRUCTURES DERIVED FROM THREE COMMON WASP SPECIES (Vespa crabro LINNAEUS, 1758, Vespa orientalis LINNAEUS, 1771 and Vespula germanica (FABRICIUS, 1793))(WILEY, 2015) Kaya, Murat; Bagriacik, Nil; Seyyar, Osman; Baran, TalatThere has been no study on the chitin structure of wasp species. Here, we selected the three most common wasp species belonging to the family Vespidae for chitin extraction and characterization. Chitin was isolated from each wasp species and characterized by Fourier transform infrared spectroscopy (FTIR), thermogravimetric analysis (TGA), X-ray diffractometry (XRD), elemental analysis (EA), and scanning electron microscopy (SEM). The chitin contents of Vespa crabro, Vespa orientalis, and Vespula germanica were 8.3, 6.4, and 11.9%, respectively. The crystalline index (CrI) values for the chitin extracted from each species were 69.88, 53.92, and 50%, respectively. The most important finding of the study is that although the same method was used to extract chitin from each of the three wasp species, the degree of acetylation was different: for V. crabro and V. orientalis it was 96.85 and 99.82% ( the chitin was extremely pure), respectively, whereas that for V. germanica the chitin was 79.83%.

The nest architectures of the three species were similar. In the P. gallicus nest, the average thickness of the fibers was 5.73 mu m, the nitrogen concentration was 26.14%, and percentages of the fibers and saliva were 77% and 23%, respectively. In the P. dominulus nest, the average thickness of the fibers was 8.7 mu m, and the nitrogen concentration was 27.42%; the percentages of fiber and saliva were 78% and 22%, respectively. In the P. nimpha nest, the average thickness of the fibers was 9.04 mu m, the nitrogen concentration was 25.82%, and the percentages of the fiber and saliva were 42% and 58%, respectively. There were differences in the amount of saliva and nitrogen concentrations.Öğe DETERMINATION OF SOME STRUCTURAL FEATURES OF THE NEST PAPER OF VESPA ORIENTALIS LINNEAUS, 1771 AND VESPA CRABRO LINNEAUS, 1758 (HYMENOPTERA: VESPINAE) IN TURKEY(INST BIOLOSKA ISTRAZIVANJA SINISA STANKOVIC, 2011) Bagriacik, NilThe aim of this study was to determine the nest materials and some physical features and elemental composition of Vespa orientalis and Vespa crabro nests. The nest surfaces were observed with a stereomicroscope and scanning electron microscope (SEM). In the V orientalis nest, the average thickness of the fibers was 13.47 mu m, the nitrogen concentration was 18.75%, the percentages of the fibers, saliva, soil and the water absorption capacity were calculated to be 20%, 20%, 60% and 91%, respectively. In the V crabro nest, the average thickness of the fibers was 11.48 mu m and the nitrogen concentration was 27.93%. The percentages of fiber, saliva and the water absorption capacity were calculated to be 23%, 77% and 100%, respectively.Öğe Extraction and elemental composition of meconium in Polistes dominulus (Hymenoptera: Vespidae)(Florida Entomological Soc, 2020) Bagriacik, NilIn the social wasps, meconium is the fecal waste of the last larval instar before pupation. Meconium is ejected from fifth (last) instar larvae after their last feeding period as a fecal mass in Polistes species. The ejection of the meconium is important for the completion of metamorphosis. The aim of this study was to determine the elemental composition of meconium from Polistes dominulus (Christ) (Hymenoptera: Vespidae). Meconia were analyzed with an energy dispersive x-ray scanning electron microscope where the average atomic percentage of C, N, O, P, K, Si, Fe, Mg, S, Al, Ca, Na, and Cl were determined. We also found that the percentage of elements in the meconia in our study were variable and probably attributable to larval diet.Öğe Knowledge Level About Insects and Mites of Health School Students(Marmara Univ, Inst Health Sciences, 2021) Bagriacik, Nil; Tekin, Cigdem SamanciObjective: Today, diseases transmitted by insects and mites still remain an important public health problem. Therefore, the training received by health personnel and their experiences on this topic is important. This study was conducted to determine the knowledge and experiences of students, who were health personnel candidates, on insects and mites likely to be encountered in hospitals or on patients Methods: This study is cross-sectional. No sample selection was made and 1st - and 4th-grade students in midwifery and nursing departments constituted the universe. Independent-samples t-tests compared knowledge to identify differences by students ` experiences and education about insects and mites, chi(2) tests compared frequency of correct knowledge answers according to experiences and education about insects and mites. Results: The participants stated that, in their daily lives, they mostly encountered cockroaches (77.9%) in their environment and lice (52.5%) on their bodies. In this study, the prominent finding was that both experiences and education were important in getting information on insects and mites. Students' ratio of thinking that they had sufficient knowledge on insects and mites, the ratio of recognizing insects and mites given in images, the mean scores of correct answers given to the propositions on insects and mites, and the knowledge of struggling methods were low. Conclusion: Today's changing environmental conditions have increased the risk of confronting epidemics related to insects and mites at any time. Therefore, it is highly important for health personnel, who are actively involved in epidemics and who consult the community, to receive effective training on insects and mites during the university period.Öğe MORPHOLOGICAL VARIATION WITHIN A COLONY OF DOLICHOVESPULA MEDIA (REITZ) (HYMENOPTERA: VESPIDAE: VESPINAE) AND ITS NEST STRUCTURE IN TURKEY(AMER ENTOMOL SOC, 2012) Bagriacik, NilA colony of Dolichovespula media (Reitz) is reported for the first time in Turkey. Morphological variation within the colony is reported. There were two and three distinctively different forms among females and males, respectively. A description of the nest is reported.Öğe Some Structural Features of Nest Materials of Polistes nimpha (Christ, 1791) in Several Ecological Conditions (Hymenoptera: Vespidae)(GAZI ENTOMOLOGICAL RESEARCH SOC, 2013) Bagriacik, NilThe aim of this study is to determine the nest materials and some physical features and elemental composition of the nests of Polistes nimpha (Christ) collected in different ecological conditions. The nests were collected in Aksaray, Adana, Konya, Nigde, Malatya, Usak provinces of Turkey. The nest surface was observed, the thickness of plant fibers was measured and an Energy Dispersive X-Ray Analysis was carried out by Scanning Electron Microscope. The percentage of the nest materials and the water absorption capacity were calculated. The results indicate that the nest architectures of the samples and the nest surface are similar. The colors of the nests are beige and grey along dark grey lines. There are differences in respect to the fiber thickness, the elemental composition and their amount, the percentage of fiber and saliva, and the water absorbency. Amounts of plant materials and oral secretions, the nitrogen concentrations in the nest walls, the nest wall's absorption capacity of P. nimpha were calculated between 37-61% and 39-63%, 25.82% and 30.22%, 217% and 764%, respectively. These differences may be related to choosing of fiber, the environment of the colonies and the production of paper.Öğe The Ultramorphological Comparison of The Venom Apparatus of Polistes gallicus (L.), Polistes dominulus (Christ) and Vespula germanica (Fab.) (Vespidae: Hymenoptera)(KAFKAS UNIV, VETERINER FAKULTESI DERGISI, 2011) Iscanoglu, Sule; Bagriacik, NilIn this study, the morphology of the venom apparatus of species of Polistes gallicus (Linneaus, 1767), Polistes nimpha (Christ, 1791) and Vespula germanica (Fabricius, 1793) were examined by Scanning Electron Microscope (SEM) (LEO 440) at 20 kV and compared the structure of the venom apparatus of the species. Samples were collected from different areas and brought to laboratory in appropriate circumtances. The venom apparatus (glands) of wasps and needles were removed under the stereomicroscope. Samples of tissues from the wasps were prepared to the method of electron microscopy. At the venom apparatus of Polistes gallicus (L.), it was observed that: The poison sac was in a muscular structure and round shape, the poison sting needles were curved at basal and sharply pointed, the palps were shorter than the sting, there were short dense hairs on apex of the palps. At the venom apparatus of Polistes nimpha (Christ), it was noticed that the poison sac was muscular, in an oval shape and lengthwise, the tip of poison sting was curled on apex towards ventral, the palps were shorter than the sting, the terminal of palps was covered with long and heavy feathers. At the venom apparatus of Vespula germanica (Fab.), it was found that the poison sac structure was muscular, in oval and circle shaped, the apex of the sting was stubby, the palps covered with long and fully feathers from basal to apex were longer than the sting. It is considered that morphological variation in terms of taxonomy is very important.
