It has used the technique of endo in 99 trees to clear a eucalyptus psyllid insect called red
The Department of Parks and Gardens is working on a new pest elimination, recently discovered by technicians, which affects the red eucalyptus gardens.
This is a small insect called a psyllid Australian Red gum (Glycaspis brimblecombei), who came to Spain in 2008, being first seen in some western provinces of Andalusia and then getting some Levantine provinces.
To remove the City Council has used the new technique of endo, which is the application to the trunk of the tree of low-pressure injections of insecticide product, what happens to the vascular system (xylem) through which the sap flows, it is distributed throughout the tree by translocation in no time.
This system is gaining ground in modern urban forestry, and offer many advantages over traditional methods of fumigation, which are:
- The speed of action, the speed with which the tree assimilated the insecticide product.
- The greater persistence, as the product exerts its action phytotherapy for a period of 12 months or more.
- The cleaning, because the product is injected in a clean and controlled, without pollution, the application can be made, therefore, in any urban area.
- The most effective of the active ingredients of the insecticide, to be distributed by the system to a larger area of tissue of the tree than traditional fumigation.
The chemical that was used is a commercial pesticide whose active ingredient is abamectin, a substance that acts primarily by ingestion, being suitable for sucking insects and leafminers, which are fixed in the intake.
The amount of eucalyptus treated by this method were 99, distributed as follows: 12 in and around the Malecon Garden, 4 in the Garden and Plaza de la Seda, 16 in the Garden of Salitre, 28 in the Chinese Garden, one in the Palace of Justice, two in the Garden of widowers and 36 in the artillery barracks.
The adult psyllid is between 2.5 and 3 mm in length and is green with orange spots and yellow.
The nymphs originated from the eggs of their eggs, which are yellow and usually placed in scattered groups, are covered by a protective substance white, cone-shaped appearance of scale, which increases in size as the nymphs grow ; they remain inside until they emerge transformed into adult insects.
As a sucking insect, bites on the leaves produce partial or total defoliation and weakening of the tree, exposing the attack of other pests or diseases.
If the attack is severe may even kill the tree.
Another effect is the production of honeydew by the insect, causing the surface of the soil around the infected tree is sticky, making it nearly impassable some sidewalks.
