There are sex pheromone traps for Diamondback moth set up across the Salinas Valley. This pheromone only attracts males of this pest. These traps were first put out on February 20th, 2019. Traps are located in Castroville, Marina, Buena Vista, Chualar, Gonzales, by the Prison (near Soledad), and Soledad. Thanks to the PCAs who are helping me with this project.
Basically, numbers of moths per day per trap have been zeros, with the exception of the trap located in Castroville. Interestingly, moths were captured in all traps last week. The actual values of those captures are presented in the below figure as yellow dots. The bigger the dot represents a larger moth capture.
It seems like a new flight for the diamondback moth is about to begin across the Salinas Valley. Additionally, there has not been a break on the life cycle of this pest in the Castroville area. Population of this moth are persistent throughout the year in that area. The trap in Castroville has always captured moths since it was set up. Populations of this moth are residents of brassica weeds, as noted in previous scouting trips.
But, what does it mean to have less than one moth per trap per day, compared to 5 moths per trap per day? Is 5 moths a high value? How is that translated to caterpillars in the field? The next step will be to pair moth trap captures with actual scout data for caterpillars found in the surrounding areas of the traps. In the meantime, the information from these traps could help us to potentially predict when caterpillars might be present in the system in larger numbers. It is more likely that we will be able to see an increase of diamondback moth caterpillars in the next two weeks. It may be good to pay attention to cole crop fields, with the goal to early detect potential damaging populations of this pest in scouted fields.
I will be updating this map with moth captures at least every other week. Stay tune!
