The purpose of these research is to identify the useful entomofauna from the agricultural crops which were taken for the study: maize and wheat. The researches were carried out in the Ezareni station, which belongs to “Ion Ionescu de la Bradˮ University of Applied Life Sciences and Environment of Iasi, Romania. The biological material was sampled by the mean of the Barber soil traps from April 30th of June until 7th of August 2018. The samples were carried out at the following dates: 30.04, 03.05, 07.05, 12.05, 15.05, 18.05, 22.05, 25.05, 05.06, 08.06, 13.06, 21.06, 05.07, 12.07, 18.07, 25.07, 01.08, 07.08. One with another, 18 samples were made for every crop. The traps were placed every six in a row. To prevent the maceration of insects, a conservative liquid was used (water+ washing powder) in proportion of 16%. After finishing the experiments, the insects were bringing to the laboratory of Entomology in order to be counted and determined. From the Coleoptera order, the most dominant species are: -within the crop of maize: Carabus nemoralis (Carabidae) - 48 samples; Dermestes maculatus (Dermestidae) - 27 samples; Coccinella septempunctata (Coccinellidae) - 33 samples; -within the crop of wheat: Pterostichus cupreus (Carabidae) - 52 samples; Dermestes maculatus (Dermestidae) - 21 samples; Coccinella septempunctata (Coccinellidae) - 30 samples.
