South American palm weevil up to Orange County?!


Recommended Posts

Posted

Hello all,

I have been following closely the spread of the South American palm weevil as it invades coastal Southern California. Looking on Google Maps, I noticed a nearly 20 mile stretch of undeveloped coastline from Camp Pendleton South in San Diego County to San Clemente in OC. This is just about the maximum one of the weevils is capable of flying, so I was hoping that this stretch of coast, assuming there are no CIDPs there which there definitely may be, would provide a natural barrier, at least temporarily, as the weevil makes its way north. But looking on Google Maps at the northern end of that coast in San Clemente, right near the OC line, I noticed these 2 CIDP that look suspiciously like they are infested with the weevils, showing the characteristic collapse and "flattening" of the crown, although none of the other CIDP around them are showing any signs of the weevil. You can tell from the trunks that they have a bit of an unusual growth habit sideways, so I was thinking this could just be a result of that, but it definitely looks suspicious. If anyone lives nearby there and can provide more recent pictures of these palms that would be helpful, depending on the feedback I will report these as weevil-infested palms. Evidently if the weevil actually has made its way this far north it is not widespread, I looked at other CIDP nearby on streetview and all looked perfectly healthy. It looks like it is still at a point there where it can be managed, if these are indeed weevils at all. Let me know your thoughts, thanks!

I found a newer streetview image of the palms from March 2023. Still kind of hard to tell if this is weevil damage or just a weird growth habit. The crowns of the palms definitely seem to have flattened a bit, but it looks like they may be flowering(?), or those may just be dead fronds. I would love anyone's input, and if any of you have seen the palm weevil in Orange County let me know. I reported these palms as potentially infested on the online South American palm weevil report form. Thanks and I really hope this weevil does not spread into OC!

I noticed that too.  I look at those palms every time I drive by on the freeway (I-5 south of San Clemente).

Do you think it's from the weevil? I really thought that ~20 mile stretch of CIDP-free coast just south of there would keep the weevils out at least for a little bit, if they have truly made their way up to OC then this is a much bigger problem, they will surely continue on up to LA. Have you noticed any other affected CIDPs around there? It seems odd that those palms appear to have been declining for several years now and yet none of the others around them seem at all affected, but I know the weevil can be selective sometimes. Would love your thoughts.

Camp Pendleton is not free of Phoenix canariensis.   There are not many, but I have seen them as volunteer plants along the I-5 freeway.

Ah got it, I was searching on Google Maps and didn't see any but I was worried that there might be a few there. This weevil poses a huge threat, and as someone who has dreamed of moving to SoCal and growing palms there I am very concerned. I really hope these CIDPs are not infested!

Pretty sure there are numerous old Canary specimens on the base itself as well.. No doubt there are likely plenty of other specimens planted in yards east of the base in Fallbrook / Rainbow, Temecula, etc..

There are definitely lots there, but to my knowledge there are little to no CIDP on this 20 mile stretch of undeveloped coastline from Camp Pendleton South to San Clemente. I would have thought, as that is just about the maximum the weevil can fly, that this would have acted as a natural barrier for the weevil, and to my knowledge the potentially infested palms pictured above are the first CIDP once you reach the northern end of that coastline.

Oh they'll fly farther than 20 miles, ..easily..   Having driven this stretch of coast many times, even if there are no Canary specimens ...Pretty sure i remember some, as Darold mentioned..  the Weevils can easily fly between Oceanside and the south edge of San Clemente in less than a couple hours.

Hop scotching from say Vista to Temecula, at the south end of the Inland Empire, is a very easy feat as well..  I have no doubt they're already there.

Tough to say it is 100% correct, since the two Weevils ( S.P.W. and Agave Snout ) look similar to un-trained eye, but there is an iNat observation of S.P.W. from near Palm Springs..  

Like so many other critters who are already expanding / will soon be expanding their ranges north as things outside the northern edge of their distribution become warmer / more favorable for establishing new populations of...  ..just going to have to get used to it's presence. 

Keep your palms healthy / don't pamper too much / allow anyone to trim / trim obsessively when it isn't necessary, and you'll be less  likely to experience problems.  Insects,  inc. Palm Weevils usually target plants under tremendous stress ..which release some kind of " i'm sick " chemical,  before opting for healthy ones. 

We have giant, terrify the easily scared folks  Palo Verde Borers which occasionally take out trees ( Grubs like dead / dying root material )..  Most often it is those that are sick / treated badly.  Still literally 1000's of Palo Verde planted in town, and growing out in the desert..

I'd rather loose a few palms / replace w/ those that are less appealing to them, and allow nature to control things,  than kill everything  ..inc Bees, Birds, ..other things that treat the Weevils as a bottomless buffet  trying to keep back one specific insect you'll never completely get rid of..

I am big on this school of thought.  mother nature has a way of bringing everything back into equilibrium ... unfortunately i will probably not live long enough to see when this day comes. 

i actually contemplated with my wife about having kids way back because man has scorched the earth of all its beauty and bringing kids to this life to only live in the remnants of man's past greed seemed so unfair.  but alas ... kids have been the most rewarding thing in my life besides gardening so i'll let mother nature takes course for all we have pillaged and raise them to respect and appreciate nature for its infinite beauty.

Last night I was walking down my Dead End  Avenue (cul-de-sac in other neighborhoods) and noticed a Canary Island Date in a neighbors yard on the Dead End behind us.  This morning I  walked down to confirm which of two houses the dying palm was in.  I assume by the way it is dying and rapidity of this, that the culprit is our weevil.  I haven't spoken with the homeowner yet but need to.  His father-in-law lives next door to him and has several old CIDP in his back lot on my street.  I fear for them being attacked soon too.

I walk this almost daily and just noticed it last night.

Devastating! I was also down in San Diego at the end of summer and the weevil damage was tragic to see. I was actually kind of surprised how many CIDPs were still alive and healthy looking though, unlike Portugal where I have family, where the red palm weevil has wiped out nearly every CIDP. Do you think it's just that the weevil hasn't gotten them yet, or are people more aware in SD County of the threat of the weevil and are treating their palms? By the way I drove by and got a picture of the original CIDPs I posted that I thought were infested up near the OC line and it looks like they may just have had a weird growth defect, it looks like they are pushing out new fronds as opposed to the flattening of the crown I thought was happening. The photo was taken August 14th. These palms are helpful because they are the first CIDP after the long undeveloped section of coast between Camp Pendleton South and San Clemente, so they would likely be the first to become infested if/when the palm weevil spreads north into OC. So far though I have not seen/read anything about them having reached there yet.

I think that most owners of CIDP here in San Diego are oblivious to the weevil threat.  There are some that are aware but there are so many CIDP owned by people that may not have planted them in the first place and don't know much about palms and aren't interested until their palm starts dying.  My sense is that the further south in San Diego County one is, the more saturation of Palm Weevils and more damaged CIDP.  As the saturation process moves north, expect the weevil to move further north.  I have not spent much time on base to assess if there is a continuous series of CIDP for them to eat and move forward from without flying longer distances.  However, there is another path for them to travel which is along the i15 corridor.  Up through Bonsall and Fallbrook's eastern edge and Rainbow, up into Temecula, Murrieta, Lake Elsinore and ultimately Corona.  From there they can spread north, east and west.  So even if Camp Pendleton proves a formidable barrier (I doubt it will be), the critters have alternative routes to getting north of San Diego County.

I used to work on Camp Pendleton and there are hundreds of old CIDP all over the interior of the base and also hundreds of them that are introduced in all the stream and wet canyons. So that ends any chances of a natural barrier.

Thank you for sharing your observations about the South American palm weevil's spread in coastal Southern California. It's essential to keep an eye on potential infestations and act swiftly to manage and prevent further spread. Your vigilance can make a significant difference in protecting these iconic palm trees. I hope that someone from the community can provide more recent pictures and confirm the situation regarding those suspicious CIDP palms in San Clemente. It's always better to err on the side of caution and report any potential infestations for proper evaluation and management. Together, we can work towards preserving these beautiful palms and the coastal ecosystem. Your efforts are appreciated!

Here in San Diego County, treatment is up to the property owner.  Last night I spoke to the homeowner that lost the tree on the street backing up to me.  The tree service that removed his infested dead palm advised it would cost $1,000 per CIDP per year for them to "treat" on a preventative basis.   Hearing that even though it is an outlier is a disincentive for most homeowners.   His was already gone, but few homeowners who aren't serious palm enthusiasts will try treating themselves in a more cost effective way to prevent infestation. 

Two doors down from the one that came down I noticed a flattening of the crown...very suspicious.   Not San Clemete but North Coastal San Diego County.

I know that neighborhood.... the "Santa" streets neighborhood, right Bob?  Like Matt's in University City.  I mentioned it somewhere, but I'm proactively treating my Bismarckia now after seeing something strange on the growth point a few weeks ago.  Next quarterly app comes with the winter solstice.  Maybe I'll do a good Druid dance around it while applying the solution for added protection.  The weevils haven't hit all the CIDP yet in that area but are already going after other species.  Bad news for all of us.

Found this in my backyard crawling on the driveway and kicked it, decapitated it apparently.   I suspect it is a weevil but don't know my bugs.  No prime candidates in my Leucadia garden for them but still worrisome with several Pritchardia which might be secondary candidates.

Unfortunately after seeing Bob's photo of the weevil larvae or pupa, I jumped to the wrong conclusion.  I looked up the various stages of the weevil so now will recognize it.  I am sorry little Carpenter Bee, I won't make that mistake again with your brethren. 

Seeing the damage of the weevil so close to home makes one a bit paranoid.

The palm in the first foto in this post is already dead, it will not recover even if you put on it today insecticide. The crown is full of the weevils.

These fotos I am attaching are to help people identify the cocoons and the weevil. You will find them on the ground under or by the palm.

If you have a CIDP and are watching it to see for infection, pay attention to the fronds on the top of the crown. If you see that the youngest fronds on the top appear eaten, as you can see in the foto with the red arrows, then it is probably infected with the weevils. This is the first evidence you may see of infection.

 I have two very nice Jubaea here in Oregon, so I am wondering how far north the weevil will migrate?  If the weevil is from South America and the Jubaea come from Central Chile, Santiago,   how is it that the Chilean Jubaea survive?  Santiago is about same parallel and climate as Southern California, so something does not make sense.

Depends whether or not there is overlap between the two.. If there is, i'm sure plenty of Jubea go untouched..

Weevil is present in Mexico and Baja.. but susceptible native and introduced palms there haven't been wiped from the earth by the beetle..  It would have been wiped out itself if it consumed every last specimen ..of it's main host  for it's kiddos.

So sad to see this. Hopefully the cities of LA and SD will at least treat the CIDPs in more famous locations with some sort of preventative treatment. One of my favorite things about Cali is seeing the large, majestic CIDPs all around.

They seem to have hit Leucadia in full force suddenly.  Last night a friend of ours a few blocks south posted a question if there was anything that could be done to rescue their CIDP which was just diagnosed as being infested.  Given that they can already see the signs, I'm sure it is a goner.

Here in San Diego County, treatment is up to the property owner.  Last night I spoke to the homeowner that lost the tree on the street backing up to me.  The tree service that removed his infested dead palm advised it would cost $1,000 per CIDP per year for them to "treat" on a preventative basis.   Hearing that even though it is an outlier is a disincentive for most homeowners.   His was already gone, but few homeowners who aren't serious palm enthusiasts will try treating themselves in a more cost effective way to prevent infestation. 

Two doors down from the one that came down I noticed a flattening of the crown...very suspicious.   Not San Clemete but North Coastal San Diego County.

Progressively getting worse on the CIDP on the street behind me that I suspected was infested.   

Noticed a third CIDP which appears infested now too.  It is in the backyard of the neighbors 4 houses up the street from me.  The skyline of the neighborhood is beginning to change.

Tracy, I drive down the 1 Leucadia to Solana today and was blown away with the devastation. Almost every CIDP had an issue.

I hope the big old one at Moonlight Beach doesn't get infested.  As you show in your photos,  it is changing the skyline around here.

That thought crossed my mind a while back. That would be such a shame!

This is so sad to see.
 

Makes my ox rhino beetle issue a bit more tolerable since the trees die young (so perhaps less owner attachment) and simple for me to remove. 

I don’t grow Phoenix partly because of photos like these.

I contacted Mark Hoddle recently of university of california in riverside to see if he has received reports of the weevil in orange or los angeles county. He answered that no, but it is only a mater of time before it arrives there. I can report that I have observed sick palms as far south as primo tapia/cuenca lechera, but nothing in Ensenada, where i live. It appears to me that the weevil is expanding slowly since 2011, but when it arrives in an area the destruction to CIDP is at least 50%. In  the areas of Tijuana where i first observed it in 2010, most CIDP are dead.
