THE IMPORTANCE OF USEFUL ARTHROPOD FAUNA IN LIMITING WHEAT PESTS IN THE CENTER OF TRANSYLVANIA

Abstract

The important role of entomophagous present in the trophic network of biocenoses, is widely debated in numerous papers. Throughout the vegetation period, field crops are invaded by a host of entomophagous, their role being important in limiting pests. Due to the importance of useful arthropod fauna for limiting wheat pests, during 2016-2017, its monitoring was carried out on the winter wheat culture, in two locations: at Turda, open field and in Bolduţ, field with agroforestry curtains, from ARDS Turda. The entomophagous collection was performed decadally with entomological net, a hundred double threads for each sample, in two variants: untreated with insecticides, and treated with insecticides. The data obtained indicates the fact that in the field with agroforestry curtains, the abundance of entomophagous it was higher, and in the variant where vegetation treatments with insecticides have been applied, the number of entomophagous was lower, compared to the untreated variant.
