Abstract


Human life is short, the whole civilized disappeared giving way other new ones, all the while human existence was based on food. Nature provides an extensive base of nutrients, but by the intelligence of man and selection managed to
exploit only time just is for real usel, so while it came to the development of agriculture, which currently is the branch of civilization socio-economic development. Through agriculture we get the best to put on our children table. The increasing demand for high quality protein from livestock forage base imposed development of ruminants, so the best results are obtained by cultivation of perennial legumes such as alfalfa (Medicago sativa), - plant that is known as,, QUEEN "of forage - ; clover (Trifolium pratense) - plant often used in treatment for various diseases -; sainfoin (Onobrychis viciifolia) and trefoil (Loturs corniculatus). Because of the importance of these plants and the benefits that underlie the culture, but also that pests can significantly reduce crop production and seed, it was established the main object of this study evaluating entomofauna present in the crops soil of alfalfa, clover, sainfoin and trefoil. To achieve the objective, it was done by placing the four cultures, traps supply units. The experimental field was located in the Rîciu area, Mures County, experiences surfaces were 2ha each. After removal traps, biological material was analyzed to identify present species in crops. Among the phytophagous species were present, we identified: Agriotes lineatus L.,Agriotes obscurus L., Agriotes sputator L., Agriotes ustulatus Schall., Athous haemorrhoidalis Fab., Athous mollis Reitt., Opatrum sabulosum L., Otiorrhynchus ligustici L., Pseudathous hirtus Hbst., Pseudathous niger L., Selatosomus aeneus Fab., Selatosomus latus Fab. și Phytodecta fornicata Brugg. Biological material collected from the four stationary are significant differences in the number of specimens collected at the culture level.
