trioderob Posted October 5, 2010 Report Share Posted October 5, 2010 (edited) this looks like it could be really bad news. this weevil has been spreading around the world the last 2 years , not just california see this web page : http://www.redpalmweevil.com/newlook/index2.htm look at the section 'news" and see the reports of "first sightings" here is the story of how they got to north america: http://www.redpalmweevil.com/newlook/RPWReport/Caribbean.htm Edited October 5, 2010 by trioderob 1 Link to comment Share on other sites More sharing options...
trioderob Posted October 5, 2010 Report Share Posted October 5, 2010 (edited) from the same site: "The larvae are responsible for damaging the palm, and once they have gained access, the death of the palm generally ensues. The larva normally never comes to the surface, since it begins its life inside the palm. Therefore, neither the damage nor the larva can be seen. However, the trunk of the palm can be infested in any parts, including the crown. The damage caused by a few larvae of the weevil is astonishing. Even one larva may cause considerable damage, and, sometimes the death of the palm." more good info and a list of palms that they are known to eat: http://www.fera.defra.gov.uk/plants/publications/documents/factsheets/redPalmWeevil.pdf Edited October 5, 2010 by trioderob 1 Link to comment Share on other sites More sharing options...

mlovecan Posted October 5, 2010 Report Share Posted October 5, 2010 (edited) Sorry to hear the Weevil has made it your way - we've had it here for about 5 years. CA palms are very important - my interest in palms greatly matured in my few years in California. Appetite-wise, these things seem to have a real sequence of preferences. We had only CIDP's getting destroyed - it was like a wave that moved through areas of the island. A few CIDP somehow seem immune - and a few were chemically-treated well and never got hit twice. But the majority succumbed - now they are looking elsewhere for food. This year I lost a Majesty to them, they attacked my CIDP X Roeb ( which has been cured for now ) and now they have found their way into my P. Dact. I haven't seen any Wasingtonias affected by RPW and am surprised they've hit queens in Italy - the local hotel owners buy queens and are under the impression they are not sought by our RPW - for now. Confidor from Bayer is what I used. After injecting an infected Palm with it ( it's a systemic and the injection occurs over a four week period ) they seem to be pretty scarce for a 10 meter or so radius from the injection. I wouldn't recommend the traps because they are VERY attracted to the vacinity by them.

trioderob Posted October 5, 2010 Report Share Posted October 5, 2010 (edited) I wonder what sort of economic impact this will have for the palm nurseries in california ? for example will there be a quarantine against palms from the entire state ? the finacial implications could be huge. also the palms that are hit by the weevel cant just be cut up and haulded away. the tree cant even be burned, it must be buried in a pit to prevent the approx 300 weevils per tree from getting away so the growth pattern of the infestation does not grow logarithmically.

DoomsDave Posted October 6, 2010 Report Share Posted October 6, 2010 Good heavens! That control regimen is a joke. No one will be able to keep up with that with palms of any size. Unless of course, the insect can be eradicated, but, I have to warn you all, remember the eradication of the infamous Medfly? (Mediterranean Fruit Fly) That was a bad pest, too. They even resorted to aerial spraying from helicopters, which nearly sparked a war between State and County Ag Commissioners and local cops. (The Ags won, more or less.)

We need to find out what that is. . . . . Dave, the problem isnt the insect , its man. In its habitat the insect stays in balance with nature, the palm is adapted to attacks and if healthy doesnt die. It is programmed to attack sick and injured palms. Freshly trimmed CIDP,s with all that sap oozing out is irresistable. The insect goes into a feeding frenzy and eats a palm not adapted to cope with the attack. Man has introduced this pest to new unadapted species and man is cutting the leaves to release the sap that sends them into feeding frenzys. 1 Resident in Bristol UK.

PalmGuyWC Posted October 6, 2010 Report Share Posted October 6, 2010 I hope Ag can get all these guys. Laguana doesn't get any freezes, so that could be trouble and allow a foot hold. I can remember when Lethal yellowing first showed up in Miami near the airport. Paul Drummond who was an expert on Coconuts reported it to the Fla. agg people. They ignored him and their attitude was, "who the hell are you to report lethal yellowing"? They allowed the disease to spread and it wiped out most of the Coconuts in S. Fla.and a lot of other species too. I hope California takes this weevil outbreak more seriously. Dick Richard Douglas Link to comment Share on other sites More sharing options...

PalmGuyWC Posted October 6, 2010 Report Share Posted October 6, 2010 Perhaps this is a time when all of us palm lovers should contact the Calif. agg people and scream.

John in Andalucia Posted October 6, 2010 Report Share Posted October 6, 2010 And it's not only about the infected palms that have to come out. Authorities will eventually revert to "damage limitation" and start looking to plant other species in their place. Nothing against Queens, but they will start popping up everywhere. In communal settings, you have to "maintain" palms by pruning, but for CIDP at least, I don't think it makes much difference. I've seen dead ones in places where it's obvious pruning hasn't taken place for several years. It's a future scenario, but one that is already happening here in Europe. I destroyed 14 RPW in one of our two Washingtonias, in an area where there are maybe less than a dozen palm trees in a square mile. Good luck to California. You need to be vigilant, and walk right up to any young CIDP or Washie if the opportunity arises, and check it over starting from mid April through to early June. RPW are slow in the air, like bumble bees, so catching them is not out of the question. In your own garden, I found that swinging a garden rake was pretty effective, as they tend to veer all over the place when taking off. THWACKK!! Advantage Wilson!

Patrick Posted October 7, 2010 Report Share Posted October 7, 2010 Interesting link with the microwave solution, Dean. Certainly a unique idea- I didn't know they made that attachment for backhoes so I'll certainly keep my eyes out for it in the near future! This looked like an Italian company so I wonder if there are any companies in the US selling the same product. This could be a money making "opportunity" for some entrepreneur out there . So what I gathered based on Dave's and Nigel's comments are that the 'recommended' containment methods are just pretty much impractical based on what we do and the volume we work with and the best way to avoid the weevils is to not prune your palm trees unless the fronds are completely dead, correct? Confidor made by Bayer is a decent treatment for affected palms. I wonder what this is called in the U.S.? Sounds simple enough. I have nothing really against Syagrus, and I guess we're a bit lucky up here in the 38th parallel because we actually do get freezes in the winter- so that may help with containment. But I'm almost certain that there is more to be concerned about than I assume. I'm interested to hear more from people who actually have dealt with the buggers. I like the tennis racket idea, too! Too bad most people like 'Joe Homeowner' don't pay enough attention to figure out why his CDIP is dying. I find it interesting that the weevil originates in Laguna Beach. I wonder why there? I suppose I could speculate for a lifetime on why the weevil wound up there first...

I think that too many people will continue to prune creating a population explosion as occurred in Spain and then they will turn to healthy unpruned trees as well. Those Egyptian plants were responsible for the scourge in Europe and now it seems in America too. I dont understand why the distribution of those contaminated plants was not stopped long ago. 1 Resident in Bristol UK.
