Beetles found on the wild black cherry Prunus serotina EHRH.

Abstract

Wild black cherry Prunus serotina is a foreign and invasive species in Poland. Initially, due to its high resistance to air pollution, this species was planted in forests. In the next years, the wild black cherry was considered an invasive species. The entomofauna of this species is poorly understood. This may be due to the foreign origin of Prunus serotina. Observations of the beetles occurring on the wild black cherry were carried out in the years 2018-2020. Single information comes from 2014. The beetles inhabiting wood, subcortical environments and developing on leaves were examined. During the research, 89 species of beetles were observed. They belonged to four groups: developing under the bark and in wood (cambiophagous, mycetophagous and xylophagous), foliophagous, zoophagous, and species hibernating and seeking shelter. Cerambycidae dominated among the xylophagous. Elateridae dominated among the species hibernating and seeking shelter. Bitoma crenata (FABR.), Lygistopterus sanguineus (L.) and Melanontus spp. are zoophagous. Most species of beetles develop in dead wood, partially decomposed by fungi. Some species of beetles, especially representatives of Cerambycidae and Curculionidae, inhabit weakened parts of the plant. Some of the observed beetles show specific preferences as to the type of habitat. Very effective generative and vegetative reproduction of the wild black cherry makes it difficult to limit its expansion by insects.
