Management of Red Palm Weevil

Save Palm Trees from Weevil Devils

1. Preventive methods: The prophylactic or preventive methods are meant to delay or prevent the entry of the palm weevil into new gardens, locations, or regions. For this purpose most vulnerable stages of the palms are treated with pesticides, cultural practices like leaf cutting are modified, phytosanitation, plant quarantine besides use of pheromone trapping system to attract and kill the adult weevils.

2. Curative methods: After detection of infestion, most suitable method of control should be applied. Detailed discussion is given elsewhere.

Please see the link http://blog.redweevil.com/2008/04/introduction/#comment-13 for advise on the useful pesticides to control red palm weevil. It is not surprising that many times, the pheromone traps may not capture any weevils, and this may be due to two reasons. One reason could be that there may not be any weevils in the vicinity or the range of attraction. The second and most common thing is improper use of the live pheromone trap. If there is a recommendation by any local expert on the pheromone trap use, you may follow that. Otherwise, I have given some suggestions and tips under the topic pheromone trapping. As a preventive measure you can apply pesticide to other ornamental palms also. I hope you will be able to save your palms. Your feedback is highly appreciated for the benefit of others.

I read with interest your very good site on the RED PALM WEEVIL. It was a terrible shock today to discover that we had our canary Palm in our garden infested with this dreaded pest.

Our gardener drilled holes, after removing the weevils and pupas which we burned, and then inserted into the holes the chemical called CONFIDOR which they use here. The tree looks very healthy and green, so I was very surprised to find it infested. It seems that the weevil has only infected one side of the tree. I plugged the holes that were injected with a cotton cloth.

I cannot see in your article any mention of named insecticides. please can you let me know which ones to use, and in what concentration. I desperately want to save my beautiful tree. I have an additional 8 WASHINHTONIA palms, which I understand are also vulnerable, so am terribly worried that I might loose them all. I have a feromone pill inside the buckets sold for this purpose, near the tree, but no weevils as yet.

I would appreciate your answer to the above at your soonest convenience, and thank you in anticipation of same.
