Resum
The space-time distribution of L. botrana was analyzed in Rioja Alta recording catches in sex pheromone traps. The mean number of weekly catches in traps was impacted both by year as by generation. Mathematical models were drawn up for the weeks of highest population density and revealed space dependence, which varied between 4.5 km and 28 km. The total number of captures per year and per trap as well as the week of the first catch were subject to the impact of year and location. The peak population for the first generation was influenced by the catch of the first week. The contour maps for the number of catches are useful for the identification of the main zones of infestation of the pest, and those generated for the time variables “week of the first catch” and “week of first generation peak” allow us to estimate the pest population peaks.
