Current red palm weevil monitoring practices rely predominantly on the use of food baited pheromone traps that include a standard bucket trap baited with an aggregation pheromone lure in addition to water and an attractive food bait such as dates. In addition to monitoring, these traps may optionally be used in protective “pull strategy” safety belt systems which consist of creating barriers along the perimeter of the field as firebreaks to avoid the pest from entering the field.
These types of traps require weekly servicing to maintain their trapping efficacy which makes their use a high maintenance strategy.
Koppert is offering an easy effective trap/lure combination using Picusan trap and a Rhynchophorus ferrugineus lure. This combination irresistibly attracts the male and female adults of red palm weevil,providing an effective tool that works 24 hours a day once installed.
When to use Picusan?
Use Picusan trap in combination with species specific pheromone and kairomone to monitor and capture red palm weevil (Rhynchophorus ferrugineus).
How does Picusan work?
The patented Picusan traps are specifically designed to capture red palm weevil. They successfully capture male and female adults and are easy to handle. Their colour and shape make them more effective than standard bucket traps and can be used without water and food baits, and without being buried.
Once baited with the pheromone and the accompanying kairomone lure, the traps function as a kill source for the red palm weevil. They irresistibly pull and attract the male and female adults towards them. They climb the pyramid of the trap and are captured inside the internal cone. This effectively reduces the reproductive potential of the population.
Pherosan Rhynchophorus ferrugineus lure is a slow release aggregation pheromone dispenser used to bait Picusan traps and is effective even at high temperatures. The dispenser allows a gradual emission providing a guaranteed long-lasting effect of up to 100 days, depending on temperature and humidity factors.
Pherosan Rhynchophorus ferrugineus is a kairomone dispenser containing 50g of ethyl acetate used in Picusan traps as a synergist to strengthen the effect of the pheromone. Its field longevity goes up to 100 days depending on temperature and humidity factors.
The Pherosan lure is available in a PE vial sealed with an aluminium seal and is packed as 2 lures per sachet. The kairomone lure is available in a plastic sealed PE flask and is packed as 2 lures per sachet. Both the pheromone and kairomone lures have a shelf life of 2 years if stored in the freezer at a temperature of -18°C, and 1 year if stored in the fridge between 4 and 6°C .
How to use Picusan
Developed for use in date palm and ornamental palm trees. Picusan traps are placed on the ground at least 5 meters away from the palm trees. Introduce the pheromone dispenser in the top basket of the trap without opening the metallic seal. In the case of the kairomone dispenser flask, remove its closing cap without damaging the plastic membrane, and place it in the white bucket of the trap.
For monitoring: Install 6 traps/ha (2 in the centre of the field spaced by 25m and 4 at the borders of the field spaced by 100 m).
For protective pull strategy safety belt: Install 12 traps/ha along the perimeter of the field with a distance of 25m between 2 traps.
