UPDATE

Hi!
I’ve read your article about the paysandisia archon. There is a solution that has been found out by a professor Peltier at INRA school in Montpellier. This year he sold it in big containers and next year, hence 2011, it should be commercialised in small containers in shops.
I copied pasted the email he sent to all of us that were interested. I hope you speak French because it’s all in French.
It’s a glue that you put on your palm tree and then 24hours later you put a layer of fat. It prevents the butterfly from laying eggs. On top of that I discussed with other people having the problem. Before spreading this glue, you should use an insecticide. Any kind will do. I bought an organic one, it’s powder and then mingled it with water and poured it from the top of the tree, so that it would go into the heart and kill larva. Then once dried, I put glue on the palm tree.

It’s easy, quite cheap but for this year you need to live near Montpelier. Next year it should be easier to buy everywhere.

Paysandisia archon moth The article below originally appeared in our Local News section in August 2008. One of our readers, Anne, has since had the dubious pleasure of seeing these moths in action.
She tells us……

“This summer we saw 2 of these very pretty moths in our garden. In November we had to chop down 5 of our palm trees which had been infested.

It seems there is nothing that can be done for the moment to prevent this happening apart from netting the palm trees to stop the moths from attacking.”

 

The Paysandisia Archon

 

The Paysandisia archon, a moth believed to have been Paysandisia archon maggot accidentally imported from Argentina and first reported on the north  Catalan coast in 2004, is responsible for munching through palm trees in Toulouges, and is gradually killing them. Palm trees have been chosen by many communes as attractive southern life ornaments to enhance village and town centres and replace the ‘platane’ or plane tree (although they are not proving to be completely suitable to the Catalan climate).

This beautiful moth, which can be easily mistaken for a butterfly, is large,with dark green front wings with brown streaking, and bright red back wings with bold black and white markings.. The adults fly from June The palm tree! to September and these moths are causing increasing concern in Europe due to the sometimes fatal damage to exotic palms. In fact, since arriving in the south of France in the mid-1990s, the species has spread along the Mediterranean coast to Spain and Italy and it is likely to continue spreading without effective preventative measures.

 Detection and control are difficult, as larvae cannot be seen or reached easily within the ‘stipe’. The larva bore through the stem or through the young leaves of the palm tree, until the palm becomes weak and can die from this. Unfortunately since this moth is not a pest in its native country, where its spread is limited by natural predators, no control method has yet been developed and it is believed that it could spread to a much larger region in the future if measures are not taken..
