Assessment of delta traps performance by numerical simulation

Abstract: Trap geometry and dispenser position can have a major impact on the characteristics of the pheromone plume exiting the trap which can, in turn, have a strong effect in the attraction and capture of moths. The aim of this study was to assess numerically the influence of changes in the geometry of a delta trap, as well as of the pheromone dispenser position inside the trap, in order to identify ways to improve its performance in terms of pheromone release.
