TRAPS AGAINST RED PALM WEEVIL

Trapping is a widely used technique for monitoring and capturing insects.

The trap is made up of the container that work as a container of the captured insects and of the sexual (Pheromones) and food attractants (Proteins, Kairomone, etc)

The shape of the trap is very important, since it is designed by studying the behavior of each species to be captured. In the case of Coleoptera such as the red palm weevil, its clumsy and heavy flight makes the truncated cone shape very effective, with its rough surface that makes it easier for the beetle to climb, since, in most of the cases, it walks inside the trap. The design of the traps allows them to be placed on the ground, without the need to be semi-buried, facilitating the inspection, cleaning and replacement of the pheromone and Kairomone. The interior design prevents captured weevils from escaping.

USE OF THE TRAPS AGAINST RED PALM WEEVIL

*We place the basket with the pheromone, that lasts more than 3 months, in the upper lid.

*In the inner bucket you can place 2 liters of water with pieces of palm trees (natural KairomonE) or a synthetic KairomonE bottle that makes the job easier.

IMPORTANT: Do not open the lid of the pheromone basket as it will spread very quickly. The same for the case of the Kairomone bottle, remove the cap and do not manipulate the diffusion film.

INSTRUCTIONS FOR PLACING THE RED PALM WEEVIL TRAP

The basic recommendations for mass capture are:

* Do not bury the traps and place them as far as possible from the palm trees. Being a high infestation area, this is less important, since we have the pest already installed in the area.

* In small plots it is recommended to place a minimum density of 4 traps per hectare, depending on the pest pressure.

* In nurseries or plantations, this density is higher (minimum of 8 traps per hectare), also reinforcing the perimeter.

 

* When possible, install traps as a protective belt to minimize the number of weevils that come in from affected neighbouring areas.

* In large areas place 1 trap per hectare.

It is convenient to keep the traps in place throughout the year, although in general, 3 flight periods are detected.
