PHEROMONES AGAINST WIREWORM (POTATOES, SALADS, etc.)

Treatment against wireworms in potatoes, lettuce and transplanted crops. Adults spend the winter buried in the soil. In the spring, once fertilized, the female beetle lays her eggs in the soil. The threadlike larva (wireworm) is born after 2 to 4 weeks. It moves in the soil to feed on the roots of the plants, which it gnaws and perforates. The development cycle of the wireworm is very long, from 1 to 5 years depending on the species: 1 year for Sordidus, 3 to 5 years for Sputator, Lineatus and Obscurus. During this entire time, the worm remains buried in the soil where it moves in search of food. We can therefore find worms of different sizes (from 2 to 25 mm) in the soil, corresponding to different stages of development. In the last year, the worm transforms into a nymph in an earthen dwelling. The adult beetle forms a month later but will not emerge from the ground until the following spring. The principle of the treatment is to use the female's specific pheromone to attract the male and trap it in order to avoid mating and laying eggs that will give the future worms. Dosage / surface: 1 to 2 trap(s) + pheromone(s) per square of garden to be protected. 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 winged trap ref 1205C 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 should be placed near the vegetables to be protected. Treatment period: from March to November.
