This small insect constitutes a headache in our gardens, below we are going to explain the problems and our solutions against the red weevil.
The red weevil is a beetle commonly known as a beetle. The main problem that this type of red beetle represents is that it devours palm trees, takes advantage of their wounds to attack from the inside to the outside and once it ends with one palm tree, it attacks another and so on. successively.
This type of reddish beetle is a great danger to palm trees , becoming one of their biggest predators.
The Red Weevil is currently the most worrying pest in the palm trees of Mallorca. It has been seen in Mallorca in:
It is a weevil of the Curculi & nidae family, very showy, with an elongated and curved face, 2 to 5 cm long and 1.2 wide, brown in color. n rusty. The larvae are legless and ivory-yellow in color with a reddish head (5 cm at maximum growth) equipped with powerful jaws. The females do the laying in the crown of the palm trees. Larvae hatch from the eggs, which live for 2 to 4 months and pupate in a cocoon made of interlaced fibers. Adults come out of there and they continue to feed on the inside of the palm tree.
The larva penetrates through the capital directly into the trunk, carving galleries up to more than 1 meter in length.
The galleries start from the crown and branch out inside the trunk. The central leaves turn yellow and wither, so that in a few weeks, almost the entire crown is affected, causing the death of the palm tree. If the galleries damage the apical bud, the palm tree dies.
Symptoms manifest with twisting of the outermost leaves on the midrib that turn straw-colored or fall off.
Damages caused by larvae are visible very late, and when the first signs of infestation appear, they are so severe that they generally result in the death of the palm tree.
In addition to the treatments once we have suffered the problem, we also advise taking control measures. Conduct flight monitoring of adults and confirm their presence using traps baited with synthetic attractants (aggregation pheromones and plant synergists or cairomones).
Very affected or dead palm trees should be uprooted and burned to prevent the emergence of adults and their dispersal.
It consists of applying the insecticide product on the upper part of the trunk and on the bud with plenty of product so that it penetrates the interior galleries that the insect has been able to make.
It consists of the injection & nbsp; of the phytosanitary product or nutritive substance (fertilizer) to the vascular system of the palm tree (basically the xylem) through its sap. In this way it directly attacks the beetle while feeding on the plant.
