Follow on Google News | Pheromone and Pest Control-Alfa ChemistryBy: Alfa Chemistry In 1967, Harry Shorey, an entomologist from the University of California, followed Porozza's research direction and first demonstrated that pheromones can be used to interrupt the mating of an insect. At that time, the experiment subject of pheromone was cabbage butterfly. But it is not clear how these pheromones work. Researchers speculate that in practice, large doses of pheromones can not only confuse male insects, but also camouflage them as female pheromone divergent sources and cause some male insects to ignore all pheromone divergent sources. The method of mating disruption has now become a technology that benefits farmers. These farmers have suffered heavy losses due to pests, because those pests are already immune to many types of pesticides. In Mexico, where about half of the tomatoes consumed in the United States are grown there, tomato pinworms have destroyed nearly half of the harvest in a year. Growers began to set tomato pinworm sex pheromones in tomato fields. These pheromones were spread through plastic pipes tied to tree stumps, tomato stems and plants. According to research statistics, only about 4% of female tomato pinworm were able to mate with male tomato pinworm in this situation. In contrast, about 50% of female tomato pinworm successfully mated in fields where no pheromone distribution source was set nearby. Pheromones can also be used as bait for pest traps. In 1980, large-scale capture of bark beetles in the devastating beetle disaster saved large areas of forests in Norway and Sweden. Researchers use pheromones as bait to spread disease to target pests, which can cause them to become infertile. After being temporarily captured, these pests are released to infect other pests. Farmers also use pheromones (https://www.alfa- End
