Insect pheromones are compounds used by insects to represent various information such as aggregation, foraging, mating, and alerting. They are the chemical molecular language of insect communication. At present, the basic control measures for pests in agricultural production mainly rely on chemical pesticides, but the long-term uncontrolled use of chemical pesticides has brought many side effects. The first is the emergence of pest resistance, which causes the use of drugs and drug concentrations to increase, the cost increases year by year, and the prevention and control of increasingly difficult; the second is to disrupt the ecological balance, while controlling a large number of natural enemies were killed, causing the pupae of secondary pests; Third, it pollutes the environment. A large amount of pesticides remain in crops, soils, rivers, lakes, and seas, and they are enriched in the human body through the form of food chain, causing another harm to humanity. Therefore, relevant research departments in many countries are currently working hard to explore and study new approaches and technologies for pest control. These studies include: the development of new, efficient, environmentally friendly, low-toxic, low-residue chemical pesticides; natural enemy insects and microorganisms The use of pesticides; insect sterilization technology and the application of insect hormones; among them, the research on the use of insect hormones, especially insect sex pheromones for pest control, is receiving increasing attention and attention.
Research on insect pheromone has been developing rapidly. Since the first insect pheromone Bombykol, has been isolated and identified, more than 2,000 insect pheromones and their analogs have been identified and synthesized worldwide, of which more than 100 insect pheromone To achieve commercial production, the production and research of Lepidoptera sex pheromones is the most extensive and comprehensive.

Nanxia Loach Powder
Nanxia loach powder is a traditional delicacy that demands great attention to detail, from the selection of ingredients to the entire preparation process. The first and most crucial step is choosing live loaches that have been caught from uncontaminated rice paddies. These fish must not be handled directly by hand, as this can damage their delicate skin and affect the final texture. Once caught, the loaches are placed in clean water for 1-2 days to allow them to expel any mud or impurities from their bodies.
Before cooking, the loaches are treated with a small amount of salt, distiller’s grains, and monosodium glutamate for about 1-2 hours. This helps infuse the flavors into the fish, enhancing its taste and aroma. When it's time to cook, cold water is added to a pot, and the cleaned loaches are gently placed inside. They are allowed to swim in the cold water before the heat is turned on, ensuring they are cooked while still moving. This technique helps keep the mud soft and the texture smooth.
After the loaches are fully cooked, hot dried powder, along with ginger, pickles, and red wine, is added to the soup. The result is a dish that is dry, tender, and full of flavor, known for its delicate and smooth texture. It's no surprise that Nanxia loach powder has gained a reputation that spreads far and wide.
Beyond its delicious taste, loach is also considered a nutritious food. According to modern nutritional analysis, fresh loach contains 18.4 grams of protein, 3.7 grams of fat, 38 milligrams of calcium, 72 milligrams of phosphorus, 0.9 milligrams of iron, and a variety of vitamins and niacin per 100 grams. Its nutritional value even slightly surpasses that of lean pork, making it an excellent choice for those seeking a healthy and flavorful meal.
Pheromone is a collective name for compounds that play a role in chemical communication between organisms, and which is the chemical molecular language of insect communication. Including sex pheromone, collection pheromone, alert pheromone, tracking pheromone, altruin, altruin, synergistic pheromone, evacuation pheromone. Pheromones are chemical substances that interact with each other and can affect each other's behavior, habits, and even development and physiological activities. Pheromone is produced by the glands in the body and is directly discharged to the outside. The pheromone is transmitted to other individuals by means of air, water and other conductive media. Pheromones are found in lower animals and higher mammals. Because the pheromone is transmitted by the external environment, it is also called pheromone. Chemical substances that interact between different species are called interspecies pheromones or heteropheres.
