The Sag town, village resident of the same name, is located in the south-west of Timis county, at a distance of about 12 km from Timisoara.

Investigated area was made up of five pieces of a 100 m2 plot (25 x 4m) arranged in series next to one another; and samples were collected periodically with an entomological net. Study the evolution of the beetles in alfalfa crops undertaken in this work made contributions to knowledge through original research of the entomofauna harmful and useful beetles of the alfalfa crops in the west of the country - the Banat Plain. At the end of these studies, it was found that in terms of coleopteran pests, the most abundant were shown to be species belonging to the family Curculionidae. During the period studied, a high abundance showed a species Sitona, Apion, Phytonomus and Phytodecta subcoccinella.
