The longicorn beetle, Dorcadion pseudopreissi Breuning (Col.: Cerambycidae) found a new and favourable environment, with expanses of lush turf and pasture grasses for the development of its root-feeding larvae in Bursa city (north-western Anatolia). The pest increased in numbers and spread naturally into new areas such as urban landscape, home lawns and football fields. Its abundance has been appeared to have increased surprisingly in the past decades and then it has caused economic damage on the turf areas. Thus, the beetle has become a major pest in turf areas of Bursa. This study was investigated to establishment the bio-ecology of D. pseudopreissi on Lolium perenne L. during 2007 and 2008 and the damage levels of the turf pest on different turf species namely L. perenne, Poa pratensis L., Festuca rubra L., F. arundinacea Schreb and Agrostis stolonifera L. (Poaceae) in field conditions during 2007-2008. Depending on weather conditions, adults emerge from the soil in mid or late March and are sexually active for ca. 1-1.5 month until middle or early May. The larvae hatch in early June, feed on grass roots during June- mid August. In damage experiments, F. arundinacea was significantly less damaged than all other turf species in the 2007 year. The damage of larvae was relatively far higher in L. perenne, P. pratensis and F. rubra than that of F. arundinacea the 2008 year. In addition, the most number of larvae were found in F. arundinacea, despite the least damage was determined at this turf species. This result shows that F. arundinacea is a tolerance turf species to D. pseudopreissi larvae. In addition, a medium damage was in A. stolonifera, but it was not originated from D. pseudopreissi larvae when the damage results along with larva counting were evaluated. Thus, the result indicated that A. stolonifera is not suitable host for D. pseudopreissi larvae.
