The problem

Palm beetle problem

Monitoring adult insects and confirmation of their presence by placing pheromone traps with synthetic attractants (pheromones, synergetic, plant-based substances or kairomones).

Heavily infested or dead palm trees have to be removed and burnt in order to prevent the hatching of adult animals and avoid their distribution.

Our solution

red palm weevil treatment

The insecticide is sprayed generously onto the upper part of the trunk and the crown of the tree, in order to reach the inner tunnels built by the animals.


The pesticide or fertilizer is introduced into the vascular system of the plant through the tree sap (mainly the xylem).

+ info

The red palm weevil is the most worrying pest in the palm trees of Majorca. It has been in Majorca in:

Phoenix dactylifera
Phoenix canariensis

It is a weevil from the Curculionidae family, very showy, with long curved face, from 2 to 5 cm long , 1.2 cm wide and a rusty brown colour.

Larvae have no legs and have yellow and ivory colours with a red head (5 cm is the maximum growth) and equipped with powerful jaws.

Females do the laying in the crown of the palm trees. The eggs hatch into larvae which live from 2 to 4 months in the pupa, in a cocoon made with interwined fibers. Adults come out from there and continue feeding on, from the inside part of the palm.

The larva enters by the capital, directly to the trunk, carving galleries up more than 1 meter length. The galleries depart from the crown and branch out with the trunk. The central leaves go yellow and whiter, so in a few weeks, practically the entire crown is affected, causing the death of the palm.

If the galleries damage the apical yolk, the palm dies.

The symptoms are manifested with kinks of the most external leaves, on the central nerve, acquiring a straw color or they fall down.

The damages caused by the larvae are visible very late, and when he first symptoms of infestation appear, they are so serious that they generally result in the death of the palm.
