Hibernating arthropods’ complex in the plum tree orchard under the influence of green manures and nectariferous plants [Articol]

Abstract

The work represents the highlighting of the arthropod complex, which populates and hibernates in the cardboard trap belts of the plum orchard influenced by green manures and nectariferous crops. This complex is composed of phytophagous, saprophagous, predators and parasites. In the trapping belts, polyphagous species of five families of spiders dominated, which constituted an average of 33.5% of the total individuals highlighted, and coccinellids (seven species) - an average of 6.5%. The parasitoid Scambus inanis achieved a degree of parasitism of moth larvae in average 29.4%. The highest percentage was recorded in the standard and experimental variants (46.0% and 35.3%) respectively.
