Description
Summary:The collections of weevils carried out using the method of Barber soil trap lines in the Botanical Garden of the Perm State National Research University (Perm) during two full growing seasons (from April to November 2021 and 2022) were analyzed. In total, more than 2000 specimens, belonging to 43 species from two families (Curculionidae and Brentidae) were collected. Eight species were first discovered in the fauna of Perm krai; six of them are alien or cryptogenic weevils. Two alien species ( Exomias pellucidus and Otiorhynchus smreczynskii ) are numerous in the collections (they make up about 50% of the sample in total). It has been shown that they have sharp differences in biotopic and trophic preferences, as well as in the timing of seasonal imago activity. Among the weevils of the botanical garden, eurybionts and representatives of the pioneer (ruderal-segetal) complex make up a total of 88%, while forest species are rare.
