Faunistic review of Polish Platypodinae and Scolytinae (Coleoptera: Curculionidae)

Faunistic review of Polish Platypodinae and Scolytinae (Coleoptera: Curculionidae) Based on a survey of the literature and collections, the distributions of the Platypodinae and Scolytinae (Curculionidae) within the present-day borders of Poland are summarized. An updated and annotated checklist is given of Polish pinhole borers (1 genus, 1 species) and bark beetles (35 genera, 110 species). Carphoborus cholodkovskyi Spessivtsev has been removed from the list; the presence of Hylastinus obscurus (Marsham), Pteleobius kraatzii (Eichhoff), Pityophthorus exsculptus (Ratzeburg), Cryphalus saltuarius Weise, Thamnurgus kaltenbachii (Bach), T. varipes Eichhoff, Pityogenes irkutensis monacensis Fuchs, P. saalasi Eggers, Xyleborus eurygraphus (Ratzeburg) and X. pfeilii (Ratzeburg), reported by previous authors, needs to be confirmed by new findings. Pitophthorus carniolicus Wichmann, Xylosandrus germanus (Blandford) and Crypturgus subcribrosus Eggers were recorded generally from Poland. Hylastes plumbeus Blandford, Phloeosinus aubei (Perris), Gnathotrichus materiarius (Fitch), Orthotomicus erosus (Wollaston), Scolytus sulcifrons Rey and Trypodendron laeve Eggers (Knížek 2011) were erroneously recorded from Poland.

The Saproxylic Beetle Corticaria bella Redtenbacher, 1847 (Coleoptera: Cucujoidea: Latridiidae) in Europe: Distribution and Habitats

Abstract All available information on the distribution and habitat requirements of saproxylic beetle Corticaria bella Redtenbacher in Europe is presented. The first record of C. bella in Finland (new country record) is based on museum specimens. Data on the occurrence of this species in Greece is supplemented based on specimens from a private collection. As a result of our research conducted in 2009–2010, the presence of C. bella in Poland is confirmed after more than 100 years; the species was found at three new sites in the central and eastern parts of the country, in 1001-year-old oak stands. Records of C. bella in Finland and Poland shift the hitherto known distribution of this species toward the northeast. Methods of collection of C. bella and characteristics of the habitats of the species are discussed. Based on available literature, C. bella is considered a very rare and locally occurring species in Europe. It prefers deciduous forests with oak (Quercus spp.) and coniferous stands with pine (Pinus spp.). The species develops in subcortical layers of dead wood infested by wood-decaying fungi.

Insects found on black alder Alnus glutinosa (L.) Gaertn. when stands are dying back

Abstract The study gives information on insects living on the black alder Alnus glutinosa (L.) Gaertn. in those 57 alder stands which exhibited the most severe signs of dying back. The surveys revealed the presence of 28 species of insects belonging to various different orders. The most common species were Agelastica alni, Xiphydria camelus,Xyleborinus attenuatus (Bland.) (=X. alni Nissima) and Saperda scalaris. It seems that none of the species of insects identified would be expected to cause die back of alder over a large area. However, it was confirmed that insects do participate in the process of dying back of alder stands.
