Weevils are beetles belonging to the superfamily Curculionoidea, known for their elongated snouts commonly named as rostrum. This is most species-rich group in Insecta well Animalia kingdom, all they considered phytophagous. The broad nosed weevil genus of Pholicodes Schoenherr, 1826 solely Palearctic distribution with forty species. In this study, two new species artemisiae sp. nov. and hakkaricus described from eastern Turkey. Morphological taxonomic characters digitally illustrated. Ph....

Trehala are unusual insect pupal chambers that sweet and have been used as human food. They formed by only four Larinus Dejean species which develop in plant stems. This group is revised taxonomically, a new key provided. A synonymy proposed: nidificans Guibourt, 1858 [= multiguttatus Reitter, 1901, syn. n.]. Lectotypes for maculatus Gyllenhal, 1836, hedenborgi Boheman, 1845, rudicollis Petri, 1907 designated. capsulatus sp. n. from northeastern Turkey described, differentiating...

The xerophilous vegetation with characteristic insect assemblages is described in the main agricultural regions and native landscapes of Turkey. Long term intensive investigations documented vast biotic degradation soil (commonly referred to as desertification) by overgrazing, construction, recreation etc. Two types xeric landscape are under investigation: 1) natural highly specific deserts, semi-deserts, dry mountain slopes screes; 2) anthropogenic, newly emerged, floristically impoverished...

Oviposition places in the host plants of23 Lixus Fabricius species eastern Turkey were identified. nordmanni Hochhuth, L. subtilis Boheman, incanescens brevipes Brisout, sp. n. pr. ochraceus furcatus Olivier, rubicundus Zoubkoff, angustatus (Fabricius), punctiventris fasciculatus bardanae korbi Petri, and scolopax Boheman deposited eggs main stem. filiformis cardui Petri oviposited stem lateral branch of their plants. circumcinctus laid on both petiole, whereas siculus farinifer Reitter,...

This paper presents natural history observations on two species of the weevil genus Mononychus Germar (Coleoptera: Curculionidae) that feed seeds Iris L. in northeastern Turkey. The host plant schoenherrii Kolenati, 1859 is iberica Hoffmann. Eggs are laid seed capsules which larvae consume nearly all capsule and pupate. Adults new generation emerge from fly away for aestivation hibernation. punctumalbum (Herbst, 1784) develops spuria Similarly, eggs a single larva consumes only or three...

Lixus cardui is a successful biocontrol agent against scotch thistle already introduced to Australia. filiformis potential for musk thistles in native distribution areas the Palearctic. Mature larvae of both Fabricius species collected from Onopordum acanthium and Carduus nutans are described, illustrated comparative remarks presented.

The new genus Nefis gen. nov. is described within the tribe Lixini (Coleoptera: Curculionidae) and its systematic position discussed. recognized by short rectangular rostrum, trapezoidal female tergite VIII with truncate apex long setaceous posterolateral margins, visible 2-segmented labial palpi protruding sinuate dorsal of protibiae. close to Larinus Dejean, 1821, Rhinocyllus Germar, 1817, Bangasternus Gozis, 1882. Three species are from Turkey Afghanistan: attilai sp. nov., kabakovi...

We studied the life history, geographic distribution, behavior, and ecology of Larinus filiformis Petri (Coleoptera: Curculionidae) in its native range to determine whether it is worthy further evaluation as a classical biological control agent yellow starthistle, Centaurea solstitialis (Asteraceae: Cardueae). occurs Armenia, Azerbaijan, Turkey, Bulgaria has been reared only from C. solstitialis. At field sites central eastern adults were well synchronized with plant, being active mid-May...

A new Larinus species is described from Iran which constructs a pupal chamber out-side of the host plant stems, named "trehala". trehalanus sp. n. fifth trehala-constructing this genus. The Cousinia stocksii C. Winkl. (Asteraceae). larva builds up trehala on stem base and develops individually inside capsule. Then pupation generation adult emergence take place in same niche. description, differential diagnosis, illustration, short ecological notes are given for...

During exploration for new biological control agents of yellow starthistle, Centaurea solstitialis L. (Asteraceae: Cardueae), in eastern Turkey, we observed four species broad-nosed weevils (subfamily Entiminae) that are newly associated with this plant: Epiphanops persicus (Chevrolat), Eusomomorphus oligops Daniel, Altonomus modestus (Khnzorian), and Araxia cristofaroi sp. n. Host plants these recorded the first time. Adults E. feed on young spines C. capitula (flower heads), whereas A....

We present new data on the host plants, biology, and distribution of Cosmobaris discolor (Boheman, 1836) Hypolixus pica (F., 1798) (Coleoptera: Curculionidae). Larval plants are ascertained for first time both species in eastern Mediterranean region Turkey. Amaranthus spinosus L. viridis (Amaranthaceae) C. discolor. Immature stages develop inside main stem lateral branches plants. is a plant H. pica, whose immature root system. This country record

Rosehip is an important socio-economic plant in Turkey.This study was carried out with the aim to determine morphology, biology and infestation of Mecorhis ungarica (Herbst, 1783) (Coleoptera: Rhynchitidae), which damaged rosehip fruits Erzincan province 2007-2008.The conducted three steps, field surveys biological morphological studies.According results study, females laid eggs flower buds or fruits, hatched 8-12 (10.1) days, oviposition lasted 40-45 ( 40) days nature, daily fecundity...

Abstract The taxonomic identification and a re‐description of the problematic Meligethes longulus Schilsky, 1894 from eastern Turkey are presented. This species, belonging to M. coracinus complex known so far on basis single immature holo‐type, was repeatedly confused in past with other closely related taxa, thus introducing considerable instability nomenclature taxonomy whole group, involving several distinct biological species throughout southern Europe western Asia. recent re‐discovery...

Based on a study of the types species described by J. Desbrochers in genus Larinus Dejean, several nomenclatural changes are proposed. Lectotypes designated (or Holotypes recognized) for following names: stricticollis Desbrochers, L. interruptus breviusculus villosiventris villosicollis distinguendus senilis (Fabricius) var. rubripes crassiusculus obesulus sacer hierolosymae cribricollis elegans densicollis akbesianus rugithorax tauricus Desbrochers. Eight new synonymies proposed: ursus...

Trehala are unusual insect pupal chambers that sweet and have been used as human food (Pierce 1915). constructed on the outside of stems by larvae in genus Larinus Dejean, 1821 (Coleoptera: Curculionidae: Lixinae). New data 4 trehala constructing species were recently presented Gultekin (2008). Trehala-like capsule constructions also observed several genera Cleonini, including Conorhynchus Motschulsky, 1860, Trichocleonus Scaphomorphus 1860 Pachycerus Schoenherr, 1823 (Volovnik 2010), Lixini...

Abstract A new weevil genus, Allolarinus n. gen., with type species, demeyeri sp., is described from Congo in the tribe Lixini. The illustrations and diagnostic characteristics of this genus have been presented a table figure plates. This related to Larinus Dejean terms elytra general shape prothorax but clearly differs respect its tooth-bearing femora granulose pronotum. trapezoidal short-neck are similar those Larinus; pronotum that Lixomorphus Faust; dentate Holcolixus Voss, Erilixus...

A search for Lixini (Curculionidae: Lixinae) species housed in the Muséum National d’Histoire Naturelle, Paris and Swedish Natural History Museum, Stockholm allowed study of a part G. -A.

Types of forty-six species Lixini the genera Broconius Desbrochers, 1904, and Lixus Fabricius, 1801 were examined to evaluate their status, lectotypes designated [or holotypes recognized] when necessary. New synonyms, homonyms, combinations new names established as follows: [= 1904 syn. n.], rectirostris Faust, 1890 hom et n. = helenae Alonso-Zarazaga & Lyal, 1999 Faust subsp. infrequens Hoffmann, 1954 kraatzi Capiomont, 1875 confinis Petri, ], isfahanensis nom.
