Researches regarding the entomofauna of coleopteras (coleoptera) from some crops of N-E Moldavia

Abstract

The purpose of these research is to identify the useful entomofauna from the agricultural crops which have been taken for the study: maize and cabbage. The researches were carried out in the Adamachi station which belongs to “Ion Ionescu de la Brad” University of Iasi, Romania. The biological material was sampled by means of the Barber soil traps from 3rd of June until 13th of September 2016. In total, 15 samples were made for every crop. The traps were placed every five 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: Amara aenea (Carabidae)-5 samples; Coccinella septempunctata (Coccinellidae)-15 samples;-within the crop of cabbage:Brachinus crepitans(Carabidae)-9 samples.
