This study aimed at elaborating a forecasting tool of the phenology of the serious pest Lobesia botrana in Southwestern Spanish vineyards, by analysing data on male catches in sex pheromone traps recorded over a 12-year period. Our data confirmed the minor importance of the first generation which appears during flowering time, both in terms of male trap catches and damage of L. botrana to the inflorescences. Therefore, data related to the first flight were not further processed, although they were considered for the computation of degree-days of the following generations. The outcome of the elaboration of temperature accumulations and data on male captures for the second and third flights was a statistically acceptable linear behaviour obtained by properly transforming the variables. The models established proved to be efficient and may represent a useful tool to improve the efficacy of integrated pest management strategies targeting L. botrana in the studied region.
