The following numbers of chromosomes were found in individual species: 2n = 22, n male = 10+Xy-p in Otiorhynchus opulentus Germ., Phyllobius oblongus (L), Phyllobius arborator (Herbst), Rhinomias forticornis (Boh.). Polydrusus ruficornis (Bonsd.); 2n = 44, n male = 21+Xy-p in Lixus cardui Ol.; 2n = 36, n male = 17+Xy-p in Adexius scrobipennis Gyll., and 2n = 28, n male = 13+Xy-p in Nedyus auadrimaculatus (L.). The heterochromosomes of all species form, in the first meiotic metaphase, a parachute bivalent. The mitoses were observed and analysed in three species. The karyotype of Nedyus quadrimaculatus (L) is constituted by metacentric chromosomes; the karyotypes of Phyllobius oblongus (L) and Rhinomias forticornis (Boh.) by metacentric and submetacentric ones.10aAdexius scrobipennis10aLixus cardui10aNedyus quadrimaculatus10aOtiorhynchus opulentus10aPhyllobius arborator10aPhyllobius oblongus10aPolydrusus ruficornis10aRhinomias forticornis1 aHolecova, Milada1 aRozek, Maria1 aLachowska, Dorota  uhttps://weevil.myspecies.info/chromosome-complement-and-meiosis-eight-bisexual-species-weevil-curculionidae-coleoptera01548nas a2200169   4500008004100000020001400041245019900055210006900254260001000323300001200333490000700345520083100352653002201183653001701205100002101222856013501243       2007                        eng d  a0007-485300aA taxonomic revision, biology and morphology of immature stages of the Entedon sparetus species group (Hymenoptera: Eulophidae), egg-larval endoparasitoids of weevils (Coleoptera: Curculionidae)0 ataxonomic revision biology and morphology of immature stages of   cApril  a139-1660 v973 aThe sparetus-group of Entedon is revised. Six species are recognized for the group, including one new species, E. lucasi Gumovsky sp. n., which is described from Algeria. All species are either diagnosed or described, and illustrated, and new distribution records are provided. An illustrated dichotomous key to all species of the group is given. Biology of two species, E. thomsonianus Erdos and E. sparetus Walker, is studied in detail: both species proved to be egg-larval parasitoids of stem-boring weevils, Lixus cardui Olivier on the scotch thistle Onopordum acanthium and Gymnetron asellus (Gravenhorst) on mullein Verbascum sp., respectively. The morphology of larval stages and peculiarities of parasitoid-host relationships are described. Possible benefits of egg-larval parasitism for Entedon species are discussed.10aGymnetron asellus10aLixus cardui1 aGumovsky, A., V.  uhttps://weevil.myspecies.info/taxonomic-revision-biology-and-morphology-immature-stages-entedon-sparetus-species-group-hymenoptera01244nas a2200169   4500008004100000020001400041245017000055210006900225260000800294300001200302490000700314520056400321653001700885100001800902700001900920856013500939       2010                        eng d  a0324-077000aDescription of Surface Morphology in Male and Female Genitals of Lixus cardui Olivier, 1807 (Coleoptera: Curculionidae: Lixinae) a Scanning Electron Microscope Study0 aDescription of Surface Morphology in Male and Female Genitals of  cDec  a321-3290 v623 aThe 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.10aLixus cardui1 aErbey, Mahmut1 aCandan, Selami  uhttps://weevil.myspecies.info/description-surface-morphology-male-and-female-genitals-lixus-cardui-olivier-1807-coleoptera-curculi
