Abstract: The aim of this study was to record and compare the occurrence of adults and immature stages of honeydew moth, Cryptoblabes gnidiella (Millière), related with grape phenology in two Pinot Noir (Vitis vinifera) vineyards in Bento Gonçalves (29º10'S 51º32'O), RS, during 2004-2005. Fortnightly, immature stages were monitored in the clusters and grapevine branches, while the adults, in delta traps baited with synthetic sex pheromone. There were significant differences in the number of individuals in different phenologic stages of vineyards. The highest catches of honeydew moth were registered in the period of dry clusters. The permanence of dry cluster after harvest, could serve as refuge for C. gnidiella immatures between seasons.
