The harvesting of the material has been done by means of entomological mesh and Barber soil traps from some wheat crops in the Deleşti - Vaslui area. In the Barber traps, consisting of plastic containers height of about 10-12 cm and 8-10 cm in diameter were placed a solution of about 4% strength formalin. Six traps were used for each experimental variant, with a total of 18 traps. For entomological mesh collection, periodically, with the harvesting of the material picked up to the soil traps were made 100 threads for each variant. The material collected periodically at intervals of 10-15 days from May until harvest of wheat crop was brought to the laboratory where each sample was analyzed. The collected species were identified, which they were then grouped into groups of taxa, saturably resulting in the structure, abundance and dynamics of existing species. The most frequently collected species were: Formicomus spp Rossi, Conosoma bipunctatum Gravenhorst, Drasterius bimaculatum Rossi, Dermestes laniarius Illiger, Opatrum sabulosum Linnaeus, Gryllus spp. Linnaeus, Epicometis hirta Poda, Pterostichus marginalis Dejean, Anthicus spp. Paykull, Phyllotreta spp. Linnaeus, Tanymecus dilaticollis Gyllenhal, etc. [ABSTRACT FROM AUTHOR]

The species have been harvested from straw cereals by Barber soil traps.The gathering has been made during the growing season from spring until harvest. In the Barber traps, which consisted of plastic containers height of about 10-12 cm and 8-10 cm in diameter it was placed a solution of about 4% strength formalin. Six traps were used for each experimental variant, with a total of 18 traps. There were done many collection of materials at intervals of 10-12 days, the samples were labeled on each sample specifying: the collection time, the trap number, the number of the variant. From the collected material after it had been previously cleared of plant debris, soil particles, etc. It was washed with a jet of water more or less intense. There were then selected carabide species (Coleoptera, Carabidae) then they were determined. Finally, on the variants there were established the structure, abundance and dynamics of the collected species. Of the coleopters species the most frequently collected were: Pterostichus marginalis Dejean, Amara aenea De geer, Metabletus truncatellus Linnaeus, Harpalus distinguendus Duft., Pseudophonus rufipe De Geer ,Zabrus tenebrioides Goeze, etc. [ABSTRACT FROM AUTHOR]
