Abstract:

Xylosandrus compactus, a xylomycetophagous bark beetle species, is predominantly polyphagous and primarily phytophagous. Xylosandrus compactus is the second Xylosandrus species reported in Turkey, and it is known for its severe damage to economically valuable plants in its spreading areas worldwide. The present research, in which we also detected different hosts after the first record in Turkey, was carried out between July (2022) and February (2023). During the field studies, wilted and dried twigs with insect entrance holes were cut and brought to the laboratory for examination. As a result of our research, a total of 25 new species (Acer negundo, A. pseudoplatanus, Aesculus x carnea, A. hippocastanum, Buxus sempervirens, Carpinus betulus, Castanea sativa, Cornus sanguinea, Corylus avellana, Elaeagnus angustifolia, Juglans regia, Laburnum anagyroidis, Liriodendron tulipifera, Malus domestica, M. floribunda, Mespilus germanica, Prunus laurocerasus, Punica granatum, Quercus castaneifolia, Q. robur, Q. rubra, Tilia tomentosa, Smilax excelsa, Ulmus minor, Viburnum opulus) have been added to the host list of Xylosandrus compactus and the number of host plants raised to 32.
