The female of the red palm weevil performs the placing inside cracks and wounds. Deposit about 300-400 eggs in a few days and hatch in 3-4 days. The larvae feed on the stem (stipe) of the palm tree practicing galleries. When they complete their development pupan at the base of the leaves (palms). The adult can fly and travel up to 5 km., And does not leave the palm tree until it is completely destroyed.
Symptoms / Damage
Galleries up to 1 meter long inside the palm tree. Symptoms to detect infection
Normally the infection in the affected palms is usually detected approximately one year after its infection. It is then when the warning signs become more evident and when we must apply the treatment against the red palm weevil to be able to save them in time. Some of the symptoms presented by the affected palm trees are?
-Decaimiento of the leaves.
-The eye of the palm tree is weakened.
- Presence of galleries excavated at the insertion point of the leaves.
- Appear cocoons of the insect.
- Healthy and green leaves appear hanging, (as if they had been half cut).
When the attack affects the apical bud the palm has no chance of regrowth and dies.
During the laying period (from April to the end of October). The objective is to destroy the newly hatched larvae before they penetrate inside the head. To do this you should wet the eye of the palm tree and children if they had.
When the palm tree has already been invaded by Rhynchophorus ferrugineus and the larvae are inside, it is useless to pulverize the leaves, it is necessary to go on to a curative treatment by means of imidacloprid injections to the trunk. It takes place at the same time and with the same frequency as the previous one.
