2019 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.

The chart below summarizes the overall capture. The data is broken by 1) the Castroville location and 2) the other locations. Castroville is shown separately from the rest of the locations since it was the only one that has always had moth captures since late winter.
