OBSERVATIONS ON THE STRUCTURE, DYNAMICS AND ABUNDANCE OF EPIGEOUS ARTHROPODS IN SOME GRAPEVINE PLANTATIONS IN VRANCEA COUNTY

Abstract

The observations were made in a vineyard plantation in the Vrancea region using Barber soil traps in 2023. Two variants were used:
• Variant 1: a vineyard plantation located on a hill where chemical treatments were applied to control pathogens and pests.
• Variant 2: a vineyard plantation located on a hill where no chemical treatments were applied to control pathogens and pests.
The material collection from the traps was carried out periodically from June to August on the following dates: 21.06, 30.06, 10.07, 16.07, 26.07, 02.08, 14.08. The material collected from the traps was then cleaned of plant debris, preserved in 40% alcohol, and identified, focusing solely on epigeous arthropod species from the order Coleoptera.
The highest number of specimens and species collected belonged to the family Carabidae. Among the species collected were: Harpalus distinguendus, Harpalus tardus, Harpalus binotatus, Carabus scabriusculus, all belonging to the family Carabidae.
Other species from the order Coleoptera were also collected, belonging to the following families: Tenebrionidae, Staphilinidae, Elateridae, Curculionidae.
