    WOS: 000343230600004The scales that are external morphological characters in Brachypera Capiomont, 1868 and Hypera Germar, 1817 (Curculionidae: Hyperinae) were examined using light and scanning electron microscope (SEM). Dried museum materials were used in this study. After softening the materials, abdomens were removed to reach elytra. Similarities and differences among the species are discussed. Although the scales look alike under the light microscope, they showed a rather different pattern with SEM. The fine structure of scales was shown to be useful for comparing species

    Author Institution: Dept. of Biology, Gazi University, TurkeyAuthor Institution: Dept. of Biology, Erciyes Unversity, TurkeyThe eggs of Ceraleptus obtusus were studied with light and scanning electron microscope. The females were collected from the Sinekci mountain pass of Kas (Antalya, Turkey) and maintained under laboratory conditions. The oval shaped eggs averaged 1.35 mm in length and 0.74 mm in width. The eggs were dark brown and mat. The egg chorion surface showed a chorionic pattern resulting in irregular hexagonal patterns. There were 18-19 short pipe micropylar projections mounted at the anterior pole. The egg burster was a chitinous and sclerotized structure. Examination of a cross section of the chorion showed that it was composed of three layers

    DESCRIPTION OF SURFACE STRUCTURE OF EGGS AND FIRST INSTAR LARVAE OF AGAPANTHIA OSMANLIS REICHE & SULCY (COLEOPTERA: CERAMBYCIDAE): BASED ON SCANNING ELECTRON MICROSCOPY

    Morphology of eggs and first instar larvae of Agapanthia osmanlis Reiche & Saulcy, 1858 (Coleoptera: Cerambycidae) are described for the first time, with illustrations of the structural features obtained using light and scanning electron microscopy (SEM). A. osmanlis feeds only on hosts in the Dipsacaceae family and collected on Cephalaria procera Fish & Lall. (Dipsacaceae) from Bayburt (Kop Mountain Pass, Turkey). The female lays single eggs inside the stalks of C. procera, where the larva feeds internally. The egg is cylindrical, white, dorsally wide, narrower toward the front and back, and rounded anteriorly and posteriorly. The egg is 3.10-3.80 (3.35) mm long and 0.45-0.85 (0.58) mm wide. Under the dissection microscope, the chorion appears to be smooth, but in scanning electron microscope (SEM) magnifications, the chorion is covered with chorionic spines except for the anterior micropylar region. Each egg possesses a knob-like micropylar process at one end. Newly emerged larvae of A. osmanlis are cylindrical, C-shaped after leaving their galleries, whitish-grey, and legless

    WOS: 000352096800004PubMed ID: 25947482The spermathecal morphology of nine species belonging to the Pentatomidae (Insecta: Heteroptera) were compared by optical and scanning electron microscopy (SEM). Among the examined species [Rhaphigaster nebulosa (Poda 1761), Palomena prasina (Linnaeus 1761), Piezodorus lituratus (Fabricius 1794), Graphosoma lineatum (Linnaeus 1758), Graphosoma semipunctatum (Fabricius 1775), Aelia albovittata (Fieber 1868), Codophila varia (Fabricius 1787), Ancyrosoma leucogrammes (Gmelin 1790), Nezara viridula (Linnaeus 1758)], all spermathecae contained a spermathecal bulb (reservoir), a pumping region, distal and proximal flanges, proximal and distal spermathecal ducts, dilation of spermathecal duct and a genital chamber containing two ring sclerites, but each species had a different spermathecal morphology.Gazi University (Turkey)Gazi University [05/2006-24]We wish to acknowledge Dr. Robert Lavigne (Professor Emeritus, University of Wyoming, Laramie, Wyoming, U.S.A.) for linguistic improvement and for the incisive review of the manuscript.

    On the Male and Female Genital Structures of Phyllobius (Metaphyllobius) glaucus (Scopoli, 1763) (Coleoptera: Curculionidae: Phyllobinii) from Turkey

    Abstract: Several structures of the male genitalia (tegmen, parameres, manubrium, endophallus), and ninth abdominal sternite (spiculum gastrale) as well as the female genitalia (genital spicule and eight sternite, ovipositor, and spermatheca) of Phyllobius (Metaphyllobius) glaucus are described and illustrated for the first time as they are useful for separating P. glaucus from other congenerics

    The Evaluation of The Relation Between Nasal Polyp Etiopathogenesis and the Amount of Biofilm

    Objective: To evaluate the effect of biofilm layer on polyp formation in nasal polyposis by comparing the amount of biofilm layer on polyp tissue and the normal mucosa. Material and Methods: This study is a prospective study. 14 patients who underwent functional endoscopic sinus surgery (FESS) for nasal polyposis were evaluated. Patients were had no history of previous FESS. Tissue samples were obtained from lower turbinate (Group 1 n:14) and from nasal polyp (Group 2, n:14) of the same nasal cavity. Biofilm presence was identified using scanning electron microscopic (SEM) morphological findings. In biofilm positive samples, the presence of biofilm in less than 25% of the surface area was classified as (+), between 25-50% as (++) , and over 50% as (+++). Results: In Group 2, with SEM imaging, (+++) biofilm presence was detected in 9 patients and (++) biofilm was detected in 5 patients. In Group 1, no biofilm was detected 8 patients, while; (+++), (++), and (+) biofilm presence was detected in 1, 2, and 3 patients respectively. Significant difference was found between group 1 and group 2 with respect to the amount of biofilm according to SEM (p =0.000). Conclusion: In samples, statistically significant difference was found between polyp tissue and normal mucosa in terms of the amount of biofilm. However, further studies with larger patient series are required in order to reach a definitive conclusion on the effect of biofilm on pathogenesis of polyp

    Ultrastructural analysis of the internal sac in several species of the weevil tribe Phyllobiini (Coleoptera: Curculionidae: Entiminae)

    WOS: 000342838400009The ultrastructure of the internal sac was comparatively studied in five species of the genus Phyllobius Germar, 1824, two species of the genus Oedecnemidius Daniel, 1903 and one species of the genus Parascythropus Desbrochers, 1875, all belonging to the weevil tribe Phyllobiini (Coleoptera: Curculionidae: Entiminae). Similarities and differences between the species investigated are discussed. The total shape of internal sac is similar, but the teeth that are located in the ventral part are different in all the species. The details of the internal sac under the scanning electron microscope are important for taxonomy and could be used for separating similar species.Ahi Evran University (Project Directorate Office), TurkeyAhi Evran University [PYO-FEN.4001.020]We wish to thank Ahi Evran University (Project Directorate Office), Turkey, for financial support for this project (Project no: PYO-FEN.4001.020)

    WOS: 000287120900009The internal genitalia of both sexes of Lixus cardui OLIVIER, 1807 (Coleoptera: Curculionidae) were examined by optical and scanning electron microscope (SEM). A detailed description is provided. In lateral view, the aedeagal tube is bented and its lateral surface is strongly sclerotised. In dorsal view, the ostium which fromendophallus (internal sac) goes out, seems clearly. The suroundings of the ostium has little sclerotised membrane. The spermatheca appears like a hook shape. It consists of receptaculum seminis, spermathecal duct and accesory gland
