Attack of the Red Palm Weevil Beetle

Arriving in Andalucia, southern Spain, in 1994, the red palm weevil (Rhynchophorus ferrugineus) is causing the destruction of thousands of affected palm trees throughout Spain.

So far, no effective remedy has been found except chopping the infected trees down and burning them.

Insecticides work against the red palm weevils (Sp. picudo rojo) when tested under laboratory conditions, but out in the field they are failing miserably. Various methods have been used to spray, inject or otherwise treat trees with insecticide, but the life cycle of the red palm weevil gets slowed but not halted.

Historically, these insects belong to Southern Asia where it causes severe problems for coconut producers, but they have been advancing to the Western hemisphere since the mid 1980s, reaching Saudi Arabia in 1985, then spreading throughout the entire UAE and to Oman, reaching Iran in 1990. It was first discovered in Egypt in 1992 where it spread through the exportation of infected palms to Spain in 1994.

By 1999 it had been found in Israel, Jordan and Palestine.

Lifecycle of the red Palm Weevil

The female weevil lays about 300 eggs inside crack and fissures in the palm tree.

In 2 - 5 days these eggs hatch into larvae that look like maggots.

They bury themselves deep inside the tree eating fibrous tissue along the way.

One to three months later the larvae mature into pupae, each coccooned in a basket of fibrous strands.

They remain in the state until they emerge as fully fledged adult weevils 2 to 3 weeks later.

L*A*T*E*S*T  N*E*W*S

Last year my Phoenix palm showed visible evidence of the weevil, i.i. badly chewed fronds and a few of the grubs; subsequently, it was condemned by two experts. I was quoted €300 for its removal. However, prior to going ahead I sought the advice of my local garden centre who prescribed a certain course of treatment, although without any guarantee. The treatment required to have an insecticide called IMAXI (3 capfuls in 9 litres of water)sprayed into the crown of the palm every 20 days for 4 months and monthly thereafter. Additionally, a further 9 litres poured around the base of the palm. In my case, it has been 9 months since there was any evidence of the weevil and I am just about to prune the last two chewed fronds. All of the new growth is green and strong and the tree produces copious amounts of healthy flowers. It may not work for everyone, but it's certainly worth a try - it certainly worked for me!

Ken Turner, Urb La Marina

Quoted from Round Town News Letters Page 11 - 17 February, 2011.

Identifying Infected Trees

Because the larvae are buried deep inside the tree, it is impossible to tell if a tree is infected or not until the first signs of death appear, which may only be the yellowing of one or two leaves. By that time it is too late and the tree is dying, because it has been eaten from the inside out.

The only option left is to cut the tree down to the ground, and burn it immediately.

The trouble with burning is that it is a slow process, and many weevils escape to infect another tree.

It has been suggested that cutting then burying the tree remains in the ground may be more effective, as the insects cannot make their way up through the soil to escape.

Containment Measures

There have been attempts to control this red palm weevil by chemical means, and while this seems to work under laboratory conditions, it is a procedure that is failing miserably out in the open. Various insecticidal sprays have been used.

Israel imposed strict chemical measures to be undertaken (and the immediate burning of any infected trees) when their first outbreak appeared, and it seems to have had no effect on the rising numbers of infected trees.

Spain in 1996 banned the importation of trees from affected areas, but 4 years later relaxed this ruling because the rate of infections was continuing to rise, mainly because there was no universal control placed on all European Community member states, so there was nothing to stop people importing them from other European countries.

The importation/exportation of mature palm trees is big business. There is a lot of money to be made, or lost if this insect destroys all the palm trees.

Out of Control

No-one has yet found out how to stop this weevil spreading once the first outbreak has been reported in any country.

Just this month it has been reported that the red palm weevil has now spread to Elche, Alicante, where their palm grove was declared a UNESCO World Heritage Site in the year 2000.

Elche is the main palm growing centre in Valencia. It has the largest palm grove in Europe if not the world! I was there myself a few months ago, and it was a pleasure to drive along the wide palm-lined route from Alicante city. I am told these palms have all had to be removed.

This site here about the City of Elche even describes in its first paragraph how you know you are going into Elche because of the palm tree-lined highways!

They will need to update their website :(

The main type of palm tree affected in Spain has been the Canary Island Date Palm, phoenix canariensis

It is a mistake to say that infested palms must be eliminated. We have established a method that allows the recovering of the palms if the infestation has been detected in time. In fact we propose now an integrated strategy to eradicate the pest and save the palms. Because of the effectiveness of this strategy, many municipalities in Spain and other european countries have requested our asssistance to train professionals for the apllication of this strategy.

It is a relief to see that this pest problem may be resolved it is an awful thought that the trees might be destroyed by the pest. As it would change the landscape of the countries so dramatically. I hope the UK will make sure any plants that can carry the diseases are checked here. Although it is not as common to see Palm trees here they do grow in sheltered situations with a milder 'climate'. Thanks Izzy.

The U.S. is experiencing a similar situation with another Asian beetle affecting hard wood trees. Drastic measures are being taken to stop the spread of these tree killers. I certainly hope the actions being taken in Spain does in fact resolve the problems y'all are having! Just as I hope we have success with our situation here.

You have palm trees in the US too, Cathi. No probs with the red palm weevil there, yet? Do you know the name of this other beetle?

@2uesday - yes the palms in the UK will be under threat soon unless someone takes extra care. There are many companies in the UK who import exotic palms.

A friend of mine in India has a business selling a natural insecticide from the U.S. which is used on a variety of insect pests. It is called Garlic Barrier and is used extensively in coconut groves near Bangalore. I bet it would work in this case as well. The Indian Government and several universities have apparently tested it extensively.

The weevil is killing the palms in my garden. Three trees are infected. Do I have to report it to the town hall? I live in Catral which is fairly close to Elche.


IzzyM profile image

IzzyM 6 years ago from UK Author

Yes I think you do Maria. They may help you get rid of the weevils too, though I fear they might do so by chopping your trees down. Maybe you should try phoning the palm centre in Elche to ask what advice they have? Michel Ferry said they were trying out a new system of treating the trees, but I've got a feeling that by the time you see an outbreak in the trees, it is too late. Not too late to save the unaffected trees though.

Great read, i have been researching all day.

I have 20 or so date palms in my garden, of which 8 have been affected. Some worse than others. My gardener is constantly treating all the palms by spraying the crowns and drilling holes and injecting an insectaside solution. But at 50 euros a tree its getting very expensive.

Im currently looking to buy some traps, which ive seen in videos and articles online, but not having any joy finding the product. I assume i would have to make them myself.


IzzyM profile image

IzzyM 6 years ago from UK Author

Josh you don't say where you are, but if you are in the south of Spain, it might be worth getting in touch with the palm centre at Elche (or even your local ayuntamiento)to see if they have traps. I am so sorry to hear about your trees and hope the treatment worked.


Brian / Mojacar 6 years ago

Just caught 3 Adult Red Weevil in my 30 year old date palm tree, they came to the surface after I had watered the tree, got them cold (and dead)will inform Elche palm centre and local town hall. hope to save the tree its almost one of the family.


IzzyM profile image

IzzyM 6 years ago from UK Author

I think Elche have developed a listening device to listen for activity after the eggs have hatched. I would treat your tree NOW...I actually don't know what chemical is working against them. Maybe the council will know. By the way, the title of this hub is "Attack of the Red Palm Weevil 'Beetle' because I found that was what people were searching for.(in case you were wondering). It is really important that everyone knows what they are. I hope you can save your tree. Post back and let me know :)


Brian / Mojacar 6 years ago

I have put diluted DACOPRID on the palm and can not hear the chomping, will let you know the results after treating for a few weeks. If the palm survives this attack, is it likley to get attacked again ?. Thanks for reply.


IzzyM profile image

IzzyM 6 years ago from UK Author

I would say it is likely to get attacked again, unless all the palm weevils in your whole area are killed off. That is why it is necessary to involve the Town Hall and hope they have a program put in place to treat all the trees. Keep me updated!


Brian/Mojacar 6 years ago

The Weevil won, the palm is eaten from the middle and the new groth has died away, what a pitty nothing was found to kill it off, DACOPRID was to late and did not work in time.


IzzyM profile image

IzzyM 6 years ago from UK Author

This is my understanding of why the red palm weevil is so hard to eradicate. By the time you see an insect or evidence of attack, it is too late. I am so sorry for the loss of your tree. Might be a good idea to treat ALL the trees in the neighbourhood, even those that look healthy now. I believe the insecticide will work to prevent infestations but treatments will need to be repeated often. Who is going to pay for all this? The ayuntamientos don't have the money...neither does the Elche centre. It might be time to ask the EU for grants? We could end up losing all the palm trees if a treatment isn't found and sustained.

I've been trying to research natural predators of this insect. The trouble seems to be that while they do have natural predators, not enough study has been done on them (we are looking at S Asia nations here). I will maybe add an appeal in the main article for help from S Asian countries to identify the predators. Trouble with using insecticides is that they tend to kill all insects, even beneficial ones, as well as poison the air we have to breathe. I'm so sorry to hear about your palm trees, Lesley.

do you have any further news on natural predators i have been reading up lots on this lately and some sites do indicate that there is a worm that can be injected into trees but it is not clear and there is no info on where such a thing might be available


IzzyM profile image

IzzyM 6 years ago from UK Author

I don't Jane. The trouble with natural predators is that they won't live in Europe - they'll live in Asia where the weevil came from. We need the scientists to work on that one and then apply for the necessary permissions etc to import them. I don't know if you heard about the Harlequin ladybird - this is an ecological disaster because it was imported to deal with another insect and ended up causing even more problems itself. http://hubpages.com/living/The-Harlequin-Ladybird I'll keep an eye out for natural predators all the same. There may well be one that fits the bill without causing damage itself.

thanks for advice izzy what about traps i have emailed a few companies that are advertising but then again unclear about purchasing, without reply, we are using the insecticides but would prefer to explore other options thanks

IzzyM 6 years ago from UK Author

From what I have read, pheromone traps have worked successfully in reducing their numbers but where you buy them I have no idea. I am assuming you are in Spain, and I don't know how well you speak the language, but if you search for them in google.es using Google Chrome, when you open a page in Spanish you get the option to translate the page into English at the top underneath the taskbar. The red palm weevil is 'picudo rojo' which is a good starting point. All the websites I have come across (in English) talking about traps are outside of Spain. It would be better if you could find a local company.

I have just found an adult Red Palm Beetle on my 2 meter high Canary Palm. The palm has no apparent damage. I have purchased Dacoprid from the garden centre but do not understand the dilution instructions (they appear to to be given in percentages). The Probete brand pack comes with a little measuring spoon. Can anyone tell me how many spoonfuls per litre I should use for a first spraying of the crown and trunk?


IzzyM profile image

IzzyM 6 years ago from UK Author

Found this on a Dacoprid website : "Ornamental palm trees: control of red palm weevil and other drills, 50 cc / hl, apply spray the bud and the stipe of the plants in the indicated doses, or in the case of palms in the nursery applied through drip irrigation at a dose of 8 -10 l / ha with a maximum of 2 applications spaced 30-40 days. It can also be applied by specialized companies under the supervision of the Plant Health Service of the Autonomous Communities, through trunk injection every 45-55 days from March to November, with a dose of 4-10 cc / 1.5-2 application m in the crown of leaves. These products can be used in the control of red palm weevil and other holes in even established plants in the field of parks and gardens".

I don't know what an 'hl' is. Maybe someone will read this and correct us. The above was translated from http://www.terralia.com/vademecum_de_productos_fit...


eeny 6 years ago

Thank you for the translation IzzyM. I asked Google what the Spanish abbreviation hl meant and got the following answer: hectoliter, hectolitre, hl a metric unit of volume or capacity equal to 100 liters. So my 2.5L spray is a fortieth of 100L. So I calculate that 1/40 of 50cc=1.25cc, which I guess is 1 and a quarter measuring spoonsfull. Thank you, I am off to spray!


IzzyM profile image

IzzyM 6 years ago from UK Author

Wouldn't it make more sense for the manufacturer to just say "Use 1.25 spoonfuls per litre"? Sounds like they don't want to make it easy for people to self-treat the problem. Typical Spain - jobs for the boys!

Anyway, good luck with the spraying and come back and let us know whether or not it has been successful.

To anyone reading here with problem with red palm weevils, further research tell me that there is a nematode available to control them. There is an article here about them - http://nematodeinformation.com/biological-control-...

and the nematode can be bought here - http://www.gardenandplants.co.uk/nemasys-caterpill...

They might not ship to Spain, but you could get it sent to a UK address and then go and collect it yourself.

Remember, that if you do decide to use nematodes, please stop using chemical insecticides which will kill the nematodes too.

IzzyM 6 years ago from UK Author

I am so sorry to hear this Barrie - it looks very much as if the whole situation is out of control and we can kiss bye-bye to most of the palm trees in the whole Mediterranean basin. Try the nematodes to save the rest of your trees and stay well away from insecticides which by all accounts are failing miserably.


jane 6 years ago

hi izzy you say that the nemotode can be bought at that site, is that the catapillar killer as it dosent actually say anything about the weavil, i am keen to buy but it will be the logistics of getting them here before they expire, sorry to bring the conversation back to insecticides after they have been deemed useless but as i have started using them i will need to cont till i get another solution, when we first applied we were told to re apply after 3mths but i was told yesterday that the insecticide only kills the adults so i should re apply after 7 days when the larve becomes adult, is this true, i sprayed both directly with the insecticied and they both died i am tempted to put more chemicals on the worst affected trees in case we didn't get far enough in, will it do any harm to the trees and is it worthwhile doing dont want to waste money or uneccisarily polute the air, also a couple of trees had died b4 we started treatment i need to get these down and burn them is there any advice on the best way to do this, do the roots need burning i think the town hall said so, my spanish isn't great


IzzyM profile image

IzzyM 6 years ago from UK Author

The roots don't need burning, but while you're having the bonfire you may as well burn them too. I don't know the best way to take them down, but beware that when you do any bugs in them may escape to infect yet more trees. Just keep an eye out for them and kill any you see.

Yes the tree will need repeated and frequent insecticide applications, preferably straight into the centre of the tree where the larvae are (drill holes in the stem), unless the insecticide is systemic in which case the roots will suck up the insecticide and spread it throughout the tree so that when the weevils eat they get poisoned. All laboratory tests they have done on the palm weevil using insecticides worked in the lab but not in the field. It won't harm the trees or you to use heavy and repeated applications, but its hardly worth it if the trees still die. Still worth a try though.

Back to the nematodes,if you can get them delivered to someone's house who is visiting Spain soon, they can keep the container in their fridge until such time as they travel here and they should be OK. Yes it is the same one that kills caterpillars.

IzzyM profile image

IzzyM 6 years ago from UK Author

Jane I had to do a lot of research this morning to try and answer your questions! (wish an expert would come along and help). What I have learned is that nematodes are tiny worms that carry a bacteria that kills the host. The nematodes enter the body of their host and infect them with the bacteria, the host dies and the nematode eats the bacteria that has multiplied on the host. There is more than one type of bacteria that can be carried on the nematode. Each bacteria targets a separate species of insect. Most pesticides will not harm nematodes. They are immune. Nematodes are killed by UV rays of sun. They need to be applied on dull days or after dark. They are applied in fat-soluble solution. The hope is that the nematodes find their way into dark crevices before the sun gets up. I have not been able to determine how long a nematode can live on a tree without any host weevils to feed on. Weevils fly from tree to tree April/May and September/October. It is only during this time that pesticides and/or nematodes can affect them. Nematodes can and will kill a newly landed weevil on an uninfected tree. Pesticides do the same job. Nematodes can destroy a nest - 80% of them which still leaves 20% alive to destroy the tree or spread to neighbouring trees. I found a site that said healthy trees should be treated with a fresh application of nematodes every 3 weeks. This makes preventative measures VERY expensive.

I also learned that the red palm weevil is now infecting British palm trees and that DEFRA want to know about any new outbreak in the UK.

In short, there is no magic solution yet. It is still spreading but there are plenty of scientists working on the problem now.


jane 6 years ago

thankyou izzy for going to so much effort to answer my questions its good news that the nematodes are imune to the insecticides that will allow me to apply them to the infected trees and carry on using the insecticides on those uninfected, at the the moment, can only experiment, and if i can get myself some traps im covering all options, shame i was really excited this morning and thought the magic solution had arrived, good news to here plenty of scientists on the job lets hope they move quickly, thankyou again izzy

Read somewhere that one day to slow down the spread of the weevil is to not prune the trees at all. Even when the lower leaves have turned brown, only cut off the ends of them leaving a long stalk. They will dry up and drop off in their own time. It is one less route for the weevil to enter the tree, so it makes sense.


jane 6 years ago

not been on for a few days been other wise engaged, still not received my nematodes, or had a chance to sort out traps so no news on these, do as always though have questions, we first appiled insecticides end sept/begin oct and was advised to re apply after 3 mths, every 6 mths thereafter, which would be end dec/begin jan for nxt application, however from reading up weavil should be dormant at this time, will insecticide still be effective, is there a point, my main concern is that if i do treat them then, the nxt treatment will be may/june which will be after their other most active time of march/april, am i better to wait and nxt treat in march, also i was told recently that a big issue was a lack of water, i have to confess, i like many others, do not put much enphasis on watering palms, but was told that the problem with the weavil has been intensified this year due to the lack of rain, i was told that the weavil is not comfortable in a damp enviroment, if this is true, then extra watering is a cheap aid to discouraging this pest, in the mentime i have started to water palms more thanks for any info jane

Jane sorry didn't get back to you sooner.

IzzyM profile image

IzzyM 6 years ago from UK Author

By the way, I have learned it is better not to cut the leaves off as is normally done to 'tidy up' in the winter. Cutting the leaves off close to the bark is allowing the palm weevil to enter the tree. If you must cut off dead or dying lower leaves, leave a long stalk about 12 - 18" long if possible. It will dry and fall off in its own time.

That is so sad, Evie! Unfortunately if affected trees aren't treated,it is only a matter of time before ALL trees are lost - everyone of those grubs will be looking for a lace to lay eggs within a year or so.

Try to keep your remaining trees damage free so that the adults can't find a way in to lay eggs. Don't allow anyone to cut dead or dying lower leaves off (annual pruning). I know its in your village and not your garden, but try and spread the word.

OMG Barrie! This is shocking news indeed! Well I just have to hope that Americans have better luck trying to eliminate this pest than those in other parts of the world.

I am devastated to be removing the 4th and largest palm from my garden... fortunately I have a nursery nearby where they store all their palms, plus grow their own, so they are able to help me remove safely and spray hopefully preventing any further spread of this dreaded weavil. Frustratingly they all appear to be dead, and wondered have I acted to soon, as no rotting was present, but the leaves were drooping slightly!! It was over 8 ft and a central feature of the pool area plus I paid onver 800 euros for it so it is proving costly not only buying it, but removing it and spraying all over the garden to prevent further outbreaks... and who knows how successful this is? My home was featured on the Grand Designs Program and people will remember lorry loads of palms being delivered in fact every border of my property and paths ways are lined with these palms.. I am, as you can imagine, very anxious to hope they find a defense for this insect asap as it is having a devastating effect on the surrounding area, notwithstanding the loss of income to these palm farms, who have a crop, that no-one wants to buy. Fortunately we have a bulldozer and are burying all the affected leaves and stump and removed it with a chainsaw. I really appreciate your information and please keep up us to date with any further information to eradicate this pest. On advice from the gardeners I am planting other palms namely Washingtonia and a Date Palm in their places, but worringly on your site it appears that they can be affected as well....I am a loss at the moment to what to do...

Jenni I am so sorry to hear how badly you have been affected by the red palm weevils and am sorry I have no more information on updated treatments at the moment. The real expert here is Michel ferry, the scientific director of the Palm centre in Elche. He can be contacted through this article http://www.palms.org/palmsjournal/2002/redweevil.h...

Please check back here as the new season is starting again and maybe some new info will come to light to save the palm trees.

I have now removed my dead palm tree, by a process of sawing rings of the trunk (with a bow saw) and chopping down (with a sharp hand axe) small amounts of the trunk.

A slow but cheep process, plastic bags into the bin. Its a lot easier if you let the tree dry out over time.

The roots are a bit of a struggle, being long and thin (stong like a rope with lots of stands) my question is "the ground infected" ?, it looks OK,

Thanks Brian, "a frustrated gardener"

So far as I am aware, it shouldn't be, but it is a good idea to deep dig over the whole area anyway. That way any live grubs get buried. Sorry about your tree.
