PHEROMONES AGAINST CHERRY WORM
Treatment against the fly responsible for the cherry worm (Rhagoletis cerasi). After spending the winter buried in the ground, the flies emerge from their pupa, mate and then lay eggs. The fly pierces the skin of the cherries and lays one egg per fruit. The larva (maggot) that is born develops, causing damage: soft flesh, browning, falling of the cherry. The principle of the treatment is to use the specific pheromone of the female to attract the male and trap it in order to prevent mating and the laying of eggs that will give rise to future worms. Dosage / surface: 1 to 4 trap(s) + pheromone(s) per tree. The pheromone sachets should be kept cold (refrigerator or freezer). This product contains 2 pheromone capsules. Sold without the trap. These pheromones are used with the mixed trap ref 1204C Shipping in mainland France only. How do pheromones work? Pheromones are volatile substances secreted by living beings (animals, insects, certain plants, etc.). In insects, the pheromone is generally emitted by the female to play a sexual attraction on the male who can detect it several kilometers away. Each insect pest corresponds to a specific pheromone. The principle of the treatment is to attract the male insect by imitating the pheromone of its female to trap it and thus avoid mating and reproduction. 1. the capsule imitating the female pheromone is placed in a trap to attract the male 2. the male detects the pheromone, he thinks he is joining the female 3. the male enters the trap, he is captured, production is stopped. How to set up the pheromones? The pheromone capsule is used as soon as the sachet is opened. It must be placed in the small capsule-holder basket of the pheromone trap. The trap + pheromone assembly must be placed in the tree to be protected. Treatment period: from April to July.
