PHEROMONES AGAINST APPLE, PEAR AND WALNUT WORM
Treatment against the codling moth responsible for the apple, pear and walnut worm (Cydia pomonella). The codling moth is a lepidopteran (butterfly) whose larva penetrates inside the fruit where it develops, causing damage. The codling moth has several generations per year: first generation: spring, from May to the end of June. Lays eggs on leaves, stems, flowers. second generation: summer, from July to mid-August. Lays eggs on healthy fruits in which the caterpillar penetrates to the seeds. In the south, there may be a 3rd generation. The principle of the treatment is to use the specific pheromone of the female to attract the male and trap it in order to avoid mating and laying eggs which will give the future worms. Dosage / surface: 1 to 4 trap(s) + pheromone(s) per tree. The pheromone sachets are 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 to 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 has 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 prevent 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 bag is opened. It must be placed in the small capsule holder basket of the pheromone trap. The trap + pheromone assembly is to be placed in the tree to be protected. Treatment period: from April to August.
