Staphylinids (Coleoptera, Staphylinidae) of Ukrainian metropolises

Abstract

During hundreds of years, in large cities man has been forming a specific urban environment with original species composition of insect communities, including the most diverse group of predatory beetles – Staphylinidae family. Kyiv, Kharkiv, Dnipro are the three most populated cities of Ukraine. In the urban cenoses of these cities, over 140 species from 66 genera of Staphylinidae have been recorded. The total of 69 species (43 genera) were recorded in Kyiv, 67 (39 genera) in Dnipro and 66 (37 genera) in Kharkiv. Among them, , eight species in the catalogue of Palearctic staphylinds had not been previously recorded for Ukraine: Arpedium quadrum Grav., Atheta laticeps Thomson, Medon apicalis Kraatz, Ocalea rivularis Müll., Philonthus salinus Kiesenwetter, Quedius invreae Gridelli, Tasgius pedator Grav. and Xantholinus gallicus Coiffait. By number, common species accounted for 29 in Dnipro, 21 in Kyiv and 19 in Kharkiv. In all the metropolises, two species (Staphylinus caesareus Cederhjelm and Drusilla canaliculata (F.)) were identified as eudominants. Dominants and subdominants comprised 18–25 species. Almost two thirds of the fauna of staphylinids of the cities was classified as rare species. The lowest faunistic similarity was seen between the staphylinids of the urban cenoses of Dnipro and those in Kyiv and Kharkiv (15.3% and 17.5%), similarity was higher for Staphylinidae of Kyiv and Kharkiv (36.0%). Similarity by common species of staphylinids for Kyiv and Kharkiv equaled 73.9%, 28.2% for Dnipro and Kyiv and 37.1% for Dnipro and Kharkiv. The article offers a review of species diversity, number and ecological structure (biotopic confinedness, hygrothermal preference) of typical species of staphylinids in different urban cenoses of Kharkiv. Differences in qualitative-quantitative and ecological structures of staphylinids are related to the diversity of the conditions in a particular urban cenoses. The commonest representatives of the family in the metropolises were polytopic mesophilous carnivorous species.

Morphometric variability of ground beetles Bembidion minimum (Coleoptera, Carabidae): who should change more, males or females?

“…Detailed descriptions of the conditions of the study areas are given in articles of some authors (Gritsan et al, 2019;Baranovski et al, 2020Baranovski et al, , 2021Gorban et al, 2021). The invertebrate fauna of these territories was also described earlier (Komlyk & Brygadyrenko, 2019b;Puchkov et al, 2020;Kunakh et al, 2021) A brief description of the studied habitats is given in Table 1. The method for determining the mineralisation and pH of soil solution is also described in some articles (Komlyk & Brygadyrenko, 2019a.…”

Sensitivity of non-target groups of invertebrates to cypermethrin

“…The practical importance of ground beetles is that they regulate the number of invertebrates, including agricultural pests. At the same time, some species of Carabidae are phytophages and mixophytophages and cause great damage to agricultural and forest plants (Avtaeva et al, 2019Puchkov et al, 2020;Brygadyrenko et al, 2021).…”

Effect of global climate change on the distribution of Anchomenus dorsalis (Coleoptera, Carabidae) in Europe

“…Depending on the developed conditions, the decrease in the number of harmful insects occurs under various factors. At the same time, certain groups of entomophages act as leading agents, limiting the pest abundance at different levels (Kryzhanovskij 1983;Puchkov et al 2020). During the periods with a low number of plant-eating insects, the activity of multifeeding predators acquires significant importance, and in the case of a further increase in the number of phytophages, the leading role is played by specialized species of entomophages (Kotze et al 2011).…”
