The viability of <em>I.</em><em> typographus </em>was affected with all tested plant extracts. The insecticidal effect varied among the extracts and concentrations used. Generally the mortality of beetles increased with the concentration of extracts and a significant positive correlation between the cumulative mortality and the extract concentration was confirmed by Pearson’s correlation analysis (r = 0.910, p = 0.012 for <em>O. vulgare </em>subsp. <em>hirtum</em>, r = 0.937, p = 0.005 for <em>T. cinerariifolium</em>, r = 0.814, p = 0.048 for <em>M. fistulosa</em>). At the highest extract concentration (10%), the total cumulative mortalities reached 98% for <em>O. vulgare </em>subsp. <em>hirtum </em>and <em>T. cinerariifolium </em>extracts at the end of the bioassay (four days after treatment). The exposure of beetles to <em>M. fistulosa </em>extract decreased the survivability of <em>I.</em><em> typographus </em>the most (15%) and was followed by <em>T. cinerariifolium </em>(38%) and <em>O. vulgare </em>subsp. <em>hirtum </em>(43%). Log-rank test showed no significant difference in the survival probabilities among the extracts. These are the first tests on the insecticidal effect of plant extracts from <em>Tanacetum cineranifolium </em>and <em>Monarda fistulosa </em>against the European spruce bark beetle <em>Ips typographus</em>.</p> Danail Takov Marek Barta Milena Nikolova Danail Doychev Teodora Toshova Peter Ostoich Daniela Pilarska Copyright (c) 2024 Baltic Journal of Coleopterology 2023-12-08 2023-12-08 23 2 139 158 New additions to the fauna of the longhorn beetles in Ukraine with a new record of rare, poorly known and invasive species https://bjc.sggw.edu.pl/article/view/9162 <p>The longhorn beetles' fauna of Ukraine has been studied fairly well. Its study began in the second quarter of the 19th century and continues for about 200 years. However, despite this, previously unknown species are regularly found on the territory of Ukraine. First of all, this is due to the very large territory of the country, as well as the</p> <p>high diversity of biomes. In this paper, I presented the records of three previously unknown species of Cerambycidae for Ukraine: <em>Enoploderes sanguineus </em>Faldermann, 1837, <em>Tetrops peterkai </em>Skořepa, 2020 and <em>Neoclytus acuminatus </em>(Fabricius, 1775). In addition, I provided new data on the findings of 82 species that are rare, poor-known or invasive in Ukraine. This allowed to significantly expand the information and supplement the faunal lists for most physiographic regions of Ukraine. I also found eight climate-sensitive species whose ranges have expanded dramatically northward and into the mountains. The most likely explanation for this may be the current global climate change. For two species, I found an expansion of the ranges from east to west, which, however, can be explained by their poor study in Ukraine. At least three alien invasive species and four steppe species of the longhorn beetles have become naturalized in the most of the territory of Ukraine, where they have never been found before. I also presented new records that confirm the presence of Mediterranean species of Cerambycidae in an isolated refugium in the Crimea. Resultantly, 283 species of the longhorn beetles have been reliably registered on the territory of Ukraine to date.</p> Andrew M.

The trap's design and operational principles allowa photo-recording of the capture moment and logging parameters of air temperature and humidity at the moment of capture. These dataare then seamlessly transmitted to a server via mobile network. The adaptability of environmental parameter recording allows customization to suit specific requirements of a given study. Rigorous testing of these traps within three Natura 2000 sites in Latvia in 2003has substantiated their robust performance and efficiency. Notably, the traps exhibit versatility and can be modified and tailored for monitoring various insect species, utilizing both pheromones and lures as attractants. This innovation holds promise for advancing ecological research and monitoring endeavours pertaining to diverse insect populations.</p> Laura Taube Uldis Valainis Maksims Balalaikins Valdis Mizers Alvydas Gintaras Dmitry Telnov Copyright (c) 2024 Baltic Journal of Coleopterology 2023-12-08 2023-12-08 23 2 313 330 Two new fossil Silinae (Coleoptera, Cantharidae) from Baltic amber https://bjc.sggw.edu.pl/article/view/9185 <p>Based on inclusions in Eocene Baltic amber, two new fossil species of the family Cantharidae, namely <em>Podosilis groehni </em>sp. nov.
