Red Palm weevils found in Laguna Beach, CA

[Cristóbal]

More information about palm # 2 in Tijuana.

They call to me from the fish store yesterday to tell to me they find the eggs of the weevil by the palm, but no weevils. Today I go there and they give these to me:

2 eggs, they are closed 100%. There are weevils in the inside !

I want open them but I think it is more better send email to Mark and Christine Hoddle to ask to them what they think is the best things to do.

[MattyB]

That tree needs to be destroyed immediately!

[Jason Baker Portugal]

There are infected CIDP everywhere here in central and north Portugal. I hope they keep on chewing only the CIDP because I have very few of them (roebelini). The countryside will certainly look diferent without those Phoenix.

I have email from Christine and Mark Hoddle. They asked to me, to open the cocoons and to put them in the frezer what I find for when they come to Tijuana again. Now they are not in north america, but soon they come here for them to take to USA for analises of DNA.

I can now confirm this palm # 2 is dead from rhynchophorus palmarum. NOT red palm weevil, but black palm weevil. Same very bad news for this area.

Here are the fotos.

MATTYB: You are right this palm needs be cut very soon, i put this in email for Christine and Mark, to ask to them to confirm this with the federal and tijuana governments, to cut this palm and destroy NOW. They are in contact with these governments of this problem.

FOTO # 1 - the cocoons, before i cut them.

[Cristóbal]

FOTO # 2 - I open the cocoon and find weevil number 1.

FOTO # 3 - Weevil number 1, is dead.

[Cristóbal]

FOTO # 4 - I open cocoon # 2. Again i find one weevil.

FOTO # 5 - The 2 weevils. Both are dead.

[Cristóbal]

FOTO # 6 - The 2 weevils from close. Yes, they are rhynchophorus palmarum.

California USA, be very careful. If they are here, they are there. One can walk from where is this palm, to USA.

I forgot in previous thread to add also Pritchardia lowreyana aka macrocarpa. I do it now for the same as above reason.

[WestCoastGal]

Cristobal, your reports and photos are always so memorable. Do I understand you correctly in that the weevils were both found dead in their cocoons before being put in the freezer? If so, I wonder why they died before emerging. Bad news that they are there and clearly responsible for taking out that palm but good news that at least those two didn't survive to emerge and travel to another palm.

[MattyB]

I wonder if our cold winter weather has killed them? Are they sleeping? Maybe this is good news that they might not thrive here because we are not so tropical.....wishful thinking maybe.

Bad news from Sicilia (Sicily Italy) too

Matt, bad news I bring to you. RPW survives outside the palm till 5C, but inside the palm can withstand much lower temps due to the increased temperature because of the fermentation produced from destroyed tissues.

Rob, why not explain your post. Where is this? What is this in regards too? It helps for the hundreds that follow this thread.

[trioderob]

the photo shows what one of those weevil grub attacks can do to a Bizzie.

was a little shocked at how bad it can be

(more than a little)

in this case its The "palmetto weevil" (Rhynchophorus cruentatus)

Thanks. So Florida for this picture.

You can see why trees die so fast with infestation.

[Phoenikakias]

And you will find out unfortunately, how quickly palm growing turns to a hobby exclusively for rich people, when the rpw or a similiar borer spreads to a another climate zone without natural enemies.

WESTCOASTGAL, the persons in the fish store, they put the cocoons in the refrigerator with fish before they give them to me. I do not know if they were dead before, but obvious if they are in the refrigerator for long time the cold there kill the weevils.

MATTYB, the first palm i find in december 2010, i do not think it is some problem for them to survive here now that i find palm # 2. The palms are in the downtown of tijuana and not far from the ocean, I do not think in any night of the winter it is more colder then 4-5C.

I have email from Christine Hoddle she says the federal government of USA is worryed about the weevil but the federal government of Mexico thinks it is not some problem ! How many palms are to die from this here and also in USA in the next years, because of this wrong attitude ?

It is important to remember this is black palm weevil, not red palm weevil. But it does same thing.

[Hammer]

Pardon my lack of knowledge, but what is the difference between the red and black species? Or does it even matter for us palm lovers in this part of the world?

In their native habitat, what checks their spread and growth?

[Enzo]

Hi,

in addition to the passion for the palms, are Doctor Agronomist and Forestry.

I'm raising awareness and helping (free) some municipalities around where I live.

I would like to ask you some questions about how it intervenes in the United States:

- someone is using a preventive IMIDACLOPRID on the ground?

- which preventive treatments are realized?

- in case of infestation of an exemplary which active principles (imidacloprid, clorpirifos,....) are used?

Sorry for my english

Thanks in advance

[DoomsDave]

Enzo!

Nice to meet you.

We do use imidacloprid here.

Cristobal's reports are truly alarming.

Bump! Since the topic has come up again. What size of palms can be infected?

[picudodelapalma]

En México el problema es muy grave y continua afectando la industria del coco de agua para fruta asi como las grandes plantaciones de palmas en zonas hoteleras en el Pacifico y Caribe mexicano. Tenemos trabajando con esta plaga desde hace aproximadamente 10 años y en el estado de Chiapas iniciamos proyectos de capacitacion sobre la plaga que ataca la palma de aceitera para produccion de biodiesel, usamos metodo de trampeo con feromonas sexuales e inyectores de alta presión al tronco en la base del cogollo donde se encuentra infestado de pequeñas larvas del picudo y en un periodo de 4 a 6 meses aproximados dependiendo del grado de daño manifestado por las larvas sera su recuperacion.

Dont hope that cold keeps the Rhynchophorus ferrugineus in check,it doesnt. They thrive here in cold Melissia even though it snows annually and we get freezing nights for many days in a row with snow. Annual lows at least -3C.

[Phoenikakias]

It looks like that larvae and cocoons have enough protection from cold in the interior of the palms, where temps are much higher than in the air because of the ongoing fermentation caused by larval excrements. (the therapy protocol for infected palms suggests also the use of fungicide). Nature finds a way...

[Ron Vanderhoff]

CA Dept. of Food and Ag have been trapping the entire area for a few years now, but have not found any more following the initial discoveries. 

[Ferry]

The weevil discovered in Laguna Beach was not Rhynchophorus ferrugineus but R. vulneratus. This last specie, as R. palmarum, is far less invasive than R. ferrugineus in urban areas with Phoenix canariensis. This palm specie constitutes an extraordinary weak host of the RPW. This explains why the situation in Laguna Beach has been so easy to control compare with places invaded by R. ferrugineus where furthermore wrong measures of control have been adopted.

Bump for interested parties

[Jdiaz31089]

Hmm, after reading through the many pages here and seeing pictures, I'm wondering if this has affected palms in the San Joaquin Valley... 

I remember seeing palms show these symptoms (collapsing crown, no new growth). There was a particular, century-old P. canariensis in Los Banos at Espana's Restaurant that showed these symptoms, slowly declining over several months. I thought it was a goner, but much to my surprise, it recovered and now has a full crown. I saw another along Robertson Blvd in Chowchilla, again century-old canariensis, go into decline. over several months with no new growth. That one too recovered after about a year of being in decline.
