Review of Saproxylic Beetles in Tugai Forests of Kazakhstan

Abstract

Abstract In the review, the data about the saproxylic beetles in the tugai forests of Kazakhstan is described. The main tree and shrub species related to saproxylic beetles are reported and the beetle species diversity is presented in a table. Of the species listed in the table, 36 species of saproxylic beetles are related to Populus sp. (Populus diversifolia and P. pruinosa), 21 species to Elaeagnus angustifolia, 20 species to Tamarix sp., and 17 species to Salix sp. The least number of saproxylic beetles was related to Fraxinus sogdiana (2 species) and Halimodendron halodendron (3 species). The author detected data about the representatives of the following families of Coleoptera: Brentidae, Bostrichidae, Buprestidae, Cerambycidae, and Curculionidae on the territory of tugai forests and the arid zone of Kazakhstan. According to the used references, the most numbered family of saproxylic beetles in the tugai forests is Buprestidae: 41 species have been known. The author found out data about 17 species of Curculionidae and 10 species of Cerambycidae. Other families have a lower number of species. It means that Buprestidae is the most studied family in the tugai forests of Kazakhstan. Further research is necessary to extend knowledge about the diversity of saproxylic beetles in the tugai forests of Kazakhstan.
