The adult insect is a fly. The fertilised female lays her eggs just under the skin of the fruit. The larva that hatches feeds and develops, causing very serious damage: gnawed flesh, rot, fruit drop.
Treatment with pheromones is a 100% ecological solution to eliminate this harmful insect.
The principle is to mimic the volatile substances emitted by the female insect (female pheromone) in order to play a role of recognition and sexual attraction on males.
These are attracted and get trapped and eliminated. This prevents mating, reproduction and thus egg-laying.
Pheromones are used with a special trap and must be applied to the appropriate adhesive refills.
Position the traps when the olives have reached about 8 mm and leave them until harvesting. Use 1 trap per tree, facing north, at the beginning of the season, then thereafter up to 4 traps per tree in late August-early September.
The box contains 2 pheromone capsules. Each capsule is packaged in an airtight bag.
Pheromone sachets can be stored cold (up to 3 years in the fridge – up to 5 years in the freezer).
Dosage: 1 to 2 traps per tree
Treatment period: April to August
Duration: 4 to 6 weeks
Apply when the temperature is above 14°C.
