Contribution to knowledge of the butterflies and moths (Lepidoptera) of north-eastern Poland with a description of a new tineid species from the genus Monopis Hübner, 1825
This work contains faunistic data on the occurrence of 677 butterfly and moth species found during 2000-2008 in north-eastern Poland (Podlasie Province). The species Monopis fenestratella (Heyden, 1863), Amphisbatis elsae Svensson, 1982, Coleophora ptarmicia Walsingham, 1910 and Epermenia falciformis (Haworth, 1828) were found in Poland for the first time. Recent data are provided for five other species - Monochroa servella (Zeller, 1839), Teleiodes aenigma Sattler, 1983, Dichomeris limosella (Schläger, 1849), Aethes rutilana (Hübner, 1817) and Eana derivana (LA Harpe, 1858) - known in Poland only from historical data. The occurrence in Podlasie of 75 species is reported for the first time, and the occurrence of 6 other species is confirmed for this area after more than 50 years. This work also describes a new species, Monopis bisonella Šumpich, sp. n. A number of species are very rare in Poland and occur only locally. These include Nemapogon wolffiellus Karsholt & Nielsen, 1976, Coleophora trifariella Zeller, 1849, Sophronia chilonella (Treitschke, 1833), Syncopacma sangiella (Stainton, 1863), Helcystogramma albinerve (Gerasimov, 1929), Cochylis flaviciliana (Westwood, 1854), Acleris comariana (Lienig & Zeller, 1846), Apotomis semifasciana (Haworth, 1811), Cydia coniferana (Saxesen, 1840), Euphydryas maturna (Linnaeus, 1758), Lopinga achine (Scopoli, 1763), Scopula nemoraria (Hübner, 1799), Epirrhoe tartuensis Moels, 1965 and Schrankia taenialis (Hübner, 1809). A complete list of the species found is provided in the Appendix at the end of this work.
Trophic relationships of Lepidoptera (Insecta) occurring in the territory of Czechia to the Norway spruce (Picea abies L.) was evaluated on the basis of the excerption and critical evaluation of literature. Each species was classified into the following categories – spruce as the host plant, regular development on spruce, narrow trophic relationship, indirect relationship and episodical occurrence. The particular taxa were also characterized according to their distribution and the form of larval life was specified. The development on spruce was documented in 96 species of Lepidoptera, which represented less than 3% of taxa belonging to this group and being reported from Czechia. Of that, spruce was a common host plant for 67 species, 23 species were polyphagous and might develop on spruce, and 6 species belonged to soil species damaging spruce roots, mainly in forest nurseries. Among the species of Lepidoptera, which regularly develop on spruce in the Czech conditions, 55 species were classified. As narrow specialists with special trophic relationship to spruce, 33 taxa could be considered. There were 15 spruce species with forestry importance, which were able to outbreak their populations regularly or irregularly. Among spruce species it was possible to classify 16 taxa as rare. The provided information on Lepidoptera with trophic relationship to spruce is applicable also for other Central European areas. Besides the species with importance for forest pest management, also rare taxa, which can become endangered by climate change or by forest management, were indicated.

The paper is focused on the experiment where the effects of the cutting environment and feed of drilling on the bores roughness and cylindricity were evaluated. Dry drilling of aluminium alloys (without using cutting fluids) is an environmentally friendly machining process but also an extremely difficult task, which is due to the tendency of aluminium to adhere to the drills made of conventional materials such as high-speed steel; and therefore three cutting environments (namely two different emulsions and compressed air) were used in the experiment. The article demonstrates multicriterial optimization of input factors (cutting environment, feed) for two defined target functions: roughness and cylindricity). The measured values were subjected to mathematico–statistical Analysis of Variance (ANOVA). ANOVA was used for examining the effects of machining parameters and their contribution to the surface roughness and bores cylindricity. The optimal cutting parameters were evaluated for “Smaller-the-Better” quality characteristics of both output responses, as can be seen in our article published previously. Based on the ANOVA, we determined that cutting environment exhibited higher percentage of contribution on bores quality than feed of machining. The results show 77.37 % impact of cutting environment and 8.13 % impact of feed on quality of machined bores.
