Abstract


The lifestyle of people in the passed, present and future is based on food, without which life on Terra is impossible.Human food source is from agriculture, with all its subdivisions, which requires productions agrozootechnical be increasingly more qualitative and quantitative due to population growth on the planet. The main source of animal protein for human need, derived from ruminants, which calls for the development of their forage base. The best food for humans underlying perennial forage crops necessary to achieve Leguina animal feed. The best perennial legume forage species are: alfalfa (Medicago sativa), - plant that is known as ,,qeen of the frage"-; clover (Trifolium pratense) –a plant often used for different as a tratament for diferent diseases and therapy-; sainfoin (Onobrychis viciifolia) and trefoil (Loturs corniculatus). Because of the importance of these plants and the benefits behind the culture, but because pests can significantly reduce crop production and seed too, it was established that the main object of this study is to assess entomofauna present in the soil in crops of: alfalfa, clover, sainfoin and trefoil . To achieve the objective, it was proceed by placing in the four cultures, supply units traps. The experimental field was located in the Rîciu, Mures County,the experiences surfaces were 2ha each. After sampling traps, biological material was analyzed to identify present species in crops. The folloing Phytophase species of the present were identified: Agriotes lineatus L., Agriotes obscurus L., L. Agriotes sputum, Agriotes ustulatus Schall., Athous haemorrhoidalis Fab., Athous mollis Roitt., Opatrum sabulosum L. Otiorrhynchus ligustica L. Pseudathous hirtus Hbst., Pseudathous L. niger, Selatosomus aeneus Fab., Selatosomus latus
Fab. Phytodecta fornicator and Brugg. In Biological material collected from four stationary there are significant differences in the number of specimens collected at the culture level.
