Diamondback moth monitoring program

We have set up several sex pheromone traps along the Salinas Valley to record the population fluctuation of the diamondback moth. Corteva Agriscience has provided partial funding for the insect trapping network.

The graphs below summarizes the overall moth captures. The data is broken by 1) the Castroville location and 2) the other locations along the Valley. Castroville is shown separately from the rest of the locations since it was the only one that has always had moth captures since the beginning of this monitoring program.
