I just spoke to Tony at The California Department of Food and Agriculture (CDFA) pest hotline (800) 491-1899. I asked him what we, as palm people driving around looking at palms all day, should do if we see a damaged palm. He said, obviously, we should call the hotline and report any visually confirmed RPW infestation that we see. But also, if we observe any damaged palm that exhibits some suspicious charactaristics we can email pics and the address of the palm to:
pesthotline@cdfa.ca.gov
and they'll take those reports from that central location, where they can log all calls and emails, and then get them out to the local guys to go out and check the palms reported.
I know of several dead or dying Phoenix canariensis around that I'm going to go ahead and forward the locations of to these guys. They really appreciate the help and value the experienced and vigilant eyes of us in the palm society, and they recognize that it's going to be guys and gals like us who are probably going to be spotting any problems in the early stages.
