Abstract


The purpose of this research is that to identify the useful entomofauna of Coccinellidae (Coleoptera-Coccinellidae) within the maize crop that has been taken into this study. The researches were carried out within Adamachi station which belongs to University of Appled Sciences of Iasi, Romania. The biological material was sampled by the mean of Barber soil traps from June 3rd of 2017 until July 9th. In total, 7 samples were made. Five traps were placed in a row. In order to prevent the maceration of insects, a conservative liquid was used: water+washing powder in a proportion of 16%. After finishing the experiments within the field, the insects were brought into the Laboratory of Entomology, in order to be counted and identified. From the Coccinellidae family, the most dominant species were:  Coccinella septempunctata (63 samples); Adalia bipunctata (28 samples) and Propylaea quatordecimpunctata (25 samples).
