THE ULTRASTRUCTURAL ANALYSIS OF SCALES IN BRACHYPERA CAPIOMONT, 1868 AND HYPERA GERMAR, 1817 (COLEOPTERA: CURCULIONIDAE: HYPERINAE)

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

Histomorphology of the Male Reproductive System and Spermatogenesis of Phyllobius (Ectomogaster) fulvago Gyllenhal, 1834 (Coleoptera, Curculionidae): A Light and Scanning Electron Microscope Study

Abstract: The morphology and histology of the male reproductive system of Phyllobius fulvago were described and discussed in relation to other Coleoptera species. The results show that Ph. fulvago has two-lobed flower-shaped arranged testes, each lobe with fourteen follicles. There are two types of glands in the male reproductive system in Ph. fulvago: tubular accessory glands and lobed prostate glands. © 2021, Pleiades Publishing, Ltd

Isolation and identification of bacillus pumilus yhh-2, a potential pathogen to the alfalfa weevil (Hypera postica gyllenhal)

Alfalfa weevil (Hypera postica Gyllenhal, 1813) samples were collected from different locations in Kırşehir, Turkey, during May–August in 2014. They were immediately transferred to the research laboratory and dissected under aseptic conditions. Then serial dilutions were prepared from digestive tract samples and the spread plate technique was used for obtaining pure cultures. The conventional and molecular methods that include morphological and physiological examinations, biochemical tests, 16S rDNA sequencing, and the basic local alignment search tool (BLAST) were used for identification of the bacterial isolates. According to the findings of the present study, the YHH-2 isolate was found as the main pathogenic bacterium that dominates the digestive tract microflora of the alfalfa weevil. 16S rDNA sequencing and the BLAST data revealed that YHH-2 showed 100% similarity to Bacillus pumilus, recently described as an entomopathogenic strain. In conclusion, the results of the present study are important due to showing for the first time the presence of Bacillus pumilus YHH-2 in the digestive tract of the alfalfa weevil and it may be used as a potential biocontrol agent against the harmful effects of this insect species. © TÜBİTAK

Morphology of spermathecae of some pentatomids (Hemiptera: Heteroptera: Pentatomidae) from Turkey

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

Taxonomic Notes on Smicronyx Schoenherr, 1843 (Coleoptera: Curculionidae) from Turkey

Four species of the genus Smicronyx Schoenherr (Coleoptera: Curculionidae) were examined in this study with Smicronyx albosquamosus Wollaston, S. coecus Reich, and S. syriacus Faust reported for the first time in Turkey. Given that S. jungermanniae Wollaston, S. reichii (Gyllenhal), S. sordidus LeConte, and S. fulvus LeConte were previously reported from Turkey, there are now seven species of Smicronyx in the insect fauna of Turkey. Specimens of S. albosquamosus, S. coecus, S. syriacus, and S. jungermanniae were collected from almond trees, Amygdalus communis L., in Eastern Southern Anatolia Region of Turkey and subjected to taxonomic study using primarily genitalia and reproductive structures to provide descriptions of these species with comparisons with previous studies. © 2021 Georgia Entomological Society Inc..

Description of Surface Morphology in Male and Female Genitals of Lixus cardui Olivier, 1807 (Coleoptera: Curculionidae: Lixinae) a Scanning Electron Microscope Study

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
