The harvesting of the material has been done by means of entomological mesh and Barber soil traps from some wheat crops in the Dele?ti - 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 ...

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.

The paper is aimed at estimating the abundance of polymetallic nodules in the Pacific area is administered by the Interoceanmetal Joint Organization (IOM) using statistical and geostatistical methods. Polymetallic nodules occurring in the Clarion-Clipperton zone in the Eastern Pacific Ocean contain numerous metals, of which the most important are Co, Cu, Ni, and Mn. In the area administered by the IOM, the four genotypes of nodules are marked with the following symbols: D and D1 (diagenetic), H (hydrogenic), and H...
