Abstract

The vine moth Lobesia botrana Den et Schifff. Is one of the main pest of the Dealurile Craiovei vineyard, the damages produced by this pest can reach 25-30%. The integrate management of the vine moth is an alternative to the excessive chemification in order to control the viticultural ecosystem during the past years, this paper frame within this curent. During 2004-2006, the climatic conditions has been favourable for the develop of the Lobesia botrana species, in 2004 there has been recorded 4 maximum flights coresponding to 3 complete generations and the fourth one incomplete, in 2005 and 2006 there has been recorded 3 maximum flights coresponding for same number of generations. The attack medium frequency, of the vine moth, recorded in 2004 has been of 20,66%, 19,0% in 2005, and of 17,83% in 2006. The attack medium frequency during 2004-2006 has been of 19,2% . The efficiency of the control treatments has been ranged between 94,6% and 89,4%. The highest efficiency of 94,6% has been recorded at the V2 variant, there has been used only chemical products, followed by the V3 variant (91,4%) there has been used chemical products for controling the first 2 generations I and II of the vine moth and an biological product for the third generation III, and the fourth variant V4 (89,7%) there has been used the pyretroid product Bulldock 025 EC for controling the first generation, and the biological product Foray 48B (Biobit XL) for controling the second generation II and 8 pheromonals traps (atraBOT/ha) for controling the third generation III. For the fifth variant V5 there has been used the product Calypso 480 SC, an metamorphosis inhibitor for the arthropods, for controling the first generation and then the biological product Dipel 2xWP for the second generation II and 8 pheromonals traps (atraBOT/ha) for the third generation, at this variant there has been recorded the lowest efficiencyt 89,4%.
