Minující hmyz na dřevinách ve vybraných parcích v Brně a okolí
Flajzarová, Andrea
In the three parks in Brno and its surroundings (arboretum of the Mendel university in Brno, the arboretum Křtiny and the forest park Kalvárie in Bučovice) the diversity of mining butterflies on ornamental trees was monitored in 2017 – 2018. The aim of the final thesis was to find out the spectrum of the mining butterflies, to determine a differences in species composition of the mining butterflies on the individual study areas and measure the degree of attack in host trees. A total of 47 species of mining butterflies were found. The most species were found in the arboretum of the Mendel university (31 species), the arboretum Křtiny (19 species) and at least species were found in the forest park Kalvárie (15 species). The most species who were found belong to the family of Gracillariidae (21 species) and Nepticulidae (20 species), the less species was from the family Tischeridae (2 species), Yponomeutidae (1 species) and Coleophoridae (1 species). The most abundant were the species of lithocolletinae, especially Cameraria ohridella on Aesculus hippocastanum, Phyllonorycter platani on Platanus acerifolia and Phyllonorycter issikii on genus Tilia. Against these species should be targeted a possible protection of host trees. The most species of mining butterflies were found on the wooden plant: Quercus robur, Fagus sylvatica, Quercus faginea, Quercus pubescens, Carpinus betulus a Ulmus glabra.
