As you know, we have been monitoring armyworm flights with pheromone traps across the valley since 2018. This year, the first set of traps were put out on 4/10 near Princeton, and today we put out a few more. We checked the first traps today, and we got an average of 2 moths per night per trap. That is high for this time of year; in 2018 and 2019 we were not catching any moths until the first week of May. We will start updating our website, UC Rice Online, once a few more traps are established. Remember you can subscribe to receive email alerts every time the numbers are updated on the website.
