RED PALM WEEVIL SYMPTOMS IN WASHINGTONIA

(Washingtonia robusta, Washingtonia filifera)

It is common to hear expressions such as: “Washingtonia palms are not attacked by Red Palm Weevil” or “They are not sensitive to the plague” or the most worrisome, “I will remove the palm trees I have and plant Washingtonias.” Nothing is further from reality and the pictures shown below prove it. It is true that the preference of the red palm weevil female when laying the eggs is clear in favor of canariensis and dactiliferas palms, but it is no less true that Washingtonia suffers red palm weevil attacks that cause them to die, and as many of the attacks are basal or lateral, they are responsible for accidents similar to those of dactiliferas palms.

Do not remove the palm trees you have to replace them by Washingtonias, instead, inspect them frequently and treat them to avoid their infestation because it is much more expensive to eliminate a dead palm tree (Cutting, truck crane, transportation to landfill, etc.), than to take care of it and treat it.

Damage has been recorded in washingtonias sp., Trachycarpus, Chamaerop, Coconut trees, etc. In different ways according to the species. In the picture section, you can see some examples of attacks on these species.
