Pteleobius kraatzi

Description

Pteleobius kraatzi is an elm borer that breeds primarily in Ulmus (Ulmaceae), and only rarely on other tree species as for excample in Sorbus (Rosaceae). It attacks both the trunk and smaller branches, creating galleries under the bark. Although the intensity of the infestation is usually not high, its activity can worsen the overall health and aesthetic appearance of weakened elms. This species can transmit dangerous disease Dutch elm disease Ophiostoma novo-ulmi and is distributed widely throughout Europe. Similar to Pteleobius vittatus.
