【 摘 要 】

Seasonal fluctuation of male Grapholita molesta (Busck, 1916) (Lepidoptera: Tortricidae) was evaluated in two commercial peach orchards cv Chiripá in Bento Gonçalves, RS, from June of 2000 to July of 2002. The insects were evaluated weekly using Delta traps (two/orchard) baited with commercial synthetic sex pheromone (E-8-dodecenil-acetato + Z-8-dodecenil-acetato + Z-8-dodecenol). Four peaks were observed during peach production period: last week of August, first of November and December and second of January. Medium temperature seven days before evaluation was positively correlated with catches of male G. molesta in the traps. Information about seasonal fluctuation can be used for growers as a tool to guide insecticide treatments for pest control in peach orchards.
