Latest data concerning the spread of phytophagous Cerambycidae Coleoptern Results and Discussions The phytophagous cerambycidae acquisition were carried out in the main areas with grassy vegetation from the western part of the Tárnává plateau mainly Tärnävenilor peak, Corne$ti-Cetatea de Balta zone, steppe zones from Biia - Ocni§oara and Nature 2000 Site Sighi§oara-Tarnava Mare. The characterization of the acquisition zones and the researched habitats The Tärnävenilor Peak-. It begins from the western part of the town of Tärnäveni, Adämu§ village and is extended to the contact zone with Transylvanian Subcarphatians in east. It has the aspect of a suspended bridge with southern slopes stepper and sunny, which allows the development of an interesting grassy formations. Unfortunately, it’s pretty full of grazing areas and there are also vineyards or Pinus sylvestris forests. Corne§ti-Cetatea de Balta. It comprises a vegetal mosaic composed of oak forests and meadows quite well preserved. The best can be found on “The Face of the City Area”, Cornejti village where there are grass lands covered with Stipa sp. Others are placed in the north of Cetatea de Balta, including steppe slopes from Craiejti, where there also vegetate numerous steppe plants. Biia-Оспцоага Zone. This is the most droughty zone, almost completely without forests, similar with those from Transylvania Plain and Seca§ Plateau, characterized by the presence of numerous “glimee” type landslides among which there are natural lakes, called by natives “täuri”. The southern slopes are steep with steppe vegetation, but in higher areas from the north of the areal are subjected to grazing frequently, which has deteriorated the vegetal carpet. Sighi§oara-Cri§ Zone (placed in Nature Site 2000 Sighi§oara-Tarnava Mare). This is an area characterized by high ground, with extended forests composed of beech on the shadowy slopes and oak — holm on the sunny slopes. The meadows are mesophilic and xerophilic as well on the southern slopes, with steep slope, very frequently in the place called Spinarea Cáinelui.
