Ocorrência de Cryptoblabes gnidiella (Millière) (Lepidoptera: Pyralidae) relacionada à fenologia da videira em Bento Gonçalves, RS

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 2004RS, during -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 d… Show more

“…Even in the years when Tannat and Gewürztraminer had similar male moths caught and harvest dates, damage was much higher in the latter, suggesting the insect prefers this cultivar. Plant volatiles and/or grape fermentation may act as chemical signals to the pests indicating places suitable for copulation and oviposition ( Bisotto-de-Oliveira et al 2007). In Progreso, Cabernet Sauvignon damage and catches were very low throughout the season, although this cultivar is harvested as late as Gewürztraminer.…”
