Flutuação populacional de Argyrotaenia sphaleropa (MEYRICK, 1909) (Lep: Tortricidae) com emprego de feromônio sexual sintético na cultura da videira
[Seasonal fluctuation of the adults of Argyrotaenia sphaleropa (MEYRICK, 1909) (Lep: Tortricidae) using synthetic sexual pheromone in vineyards]

Abstract: The South American Tortricid Moth (Meyrick, 1909) (Lepidoptera: Tortricidae) is often found damaging vineyards and other temperate fruit orchards, in Southern Brazil and Uruguay. This work was conducted to study the seasonal occurrence of A. sphaleropa adults in vineyards using sexual synthetic pheromone. Based on weekly evaluation of A. sphaleropa adults caught in Delta trap baited with synthetic sexual pheromone (Z11, 13-14Ac + Z11, 13-14Al + Z11-14Al in a ratio of 4:4:1, 1000µg/septum), during 2003/2004 season, it was observed four populational peaks in a Cabernet Sauvignon vineyard. The first populational peak occurred in the beginning of October, the second in the beginning of February, the third occurred in middle of March and the forth in June. There was no significative correlation between medium temperature and pluvial precipitation pluvial on adult catches. Information about seasonal fluctuation can be used for grape growers as a tool to guide insecticide treatments for pest control in vineyards.
