Abstract For the quantitative determination of pest population dynamics and in order to establish the necessity of control treatment , an investigation regarding the harmful arthropod fauna in the vineyard from the winegrowing center Banu Mărăcine has been made in the years 2007 and 2008. Within the viticultural ecosystem from the S.D. Banu Mărăcine a number of 68 species of harmful has been identified, sistematically framed in 9 different orders. The most numerous order has been Coleoptera with 21 species, followed by the order with 16 species and order with 11 species. From the total of 68 harmful arthropods species a number of 47 species represent species harmful for grapevine and 21 indifferent species.

Key words: harmful entomofauna, key pests, potential pests, migratory species

Introduction The classification of pests after Smith and Van der Bosch (1967) comprises, besides the key species, the group of the secondary pests, which can produce damages in certain areas and conditions, also being known as occasional pests. Although they do not produce damages year after year, they must be monitorised and controlled, thus, they will not become key pests as a consequence of missing human activities. Usually these species are under the economically treshold (P.E.D.) due to their natural control. However, these occasional pests are represented first by the potential pests, which do not produce significant damages from the economically point of view, but in some cases they can fall into the group of secondary or key pests, and second by the migratory species, which proceed from other crops and can became dangerous for grapevine under certain conditions. Depending on the area, pedological and climatic conditions, key pests may occur in varied densities, leading to an determination of different damaging tresholds in different years, so that a standard integrate management can not be applied.

Material and methods For the quantitative determination of pest population dynamics and in order to establish the necessity of control treatment , an investigation reagarding the harmful arthropod fauna , in the vineyard from the winegrowing center Banu Mărăcine has been made in the years 2007 and 2008. The aim of this work was to evaluate the structure of the biocoenosys and the critical damaging treshold. In order to evaluate the harmful entomofauna from the vineyard of the S.D. Banu Maracine during the research period (2007-2008), entomological material was collected using different means and methods: collecting with the entomological net, tests in the soil or on the soil surface (on the interval between the rows), lightning traps, coloured traps, visual

The material was collected at different vegetation phases of the vine. The collected species were analysed and identified according to the determinators published in the Romanian Fauna (Panin 1951) and European Fauna (Chinery 1998).

Results and discussion Within the viticultural ecosystem from the S.D. Banu Mărăcine, 68 species of harmful arthropods have been identified (table 1), sistematically framed in 9 orders.

The most numerous order has been Coleoptera with 21 species, followed by the Lepidoptera order with 16 species, and Heteroptera order with 11 species. From the total number of 68 harmful Arthropods species, 47 species represent species harmful for grapevine and 21 indifferent species, for which the relationship to grapevine is not clear (table 2).

The structure of the damaging entomofauna in the viticultural ecosystem from S.D. Banu Mărăcine expressed as percentage is the following: damaging species for the grapevine represent 69%, and indifferent species for the vine represent 31%.

Conclusions Following the recorded results we can conclude that the major groups of vine pests from the viticultural ecosystem at S.D. Banu Mărăcine are: Key pests: vine acarians (Eriophyes vitis Page., Tetranychus urticae Koch., Panonychus ulmi Koch., and Calepitrimerus vitis Nal.) and the vine (Lobesia botrana Den et Schif., Eupoecilia ambiguella Hb., and Sparganotis pilleriana Den et Schif.). Secondary pests (occasional): Genul Anomala Sam., Pulvinaria vitis Targ., Melolontha melolontha L., Polyphylla fullo F., Potential pests: Phylloxera vastatrix Planch., Vespa spp. L., Otiorrhynchus ligustici L., Agriotes spp. L., Byctiscus betulae L. Besides these species, there are series of other species frequently encountered and considered to be migratory: Haltica ampelophaga Gue., Ceresa bubalus L., Dolycoris baccarum L., Lygus pratensis L., Amphimalon soltitialis L., Rhyzotrogus aequinoctialis Herb. Zeuzera pyrina L., Hyphantria cunea Drury. etc.
