1. Adjust chickens to eliminate fewer eggs, stop production chickens, weak chickens, frozen chickens, chickens with severe paralysis, chickens with short peaks of egg production, over- or under-lean chickens, and disease-free chickens . 2. Increase feed nutrition After a long egg-laying period and hot summer season, old laying hens are already very tired. After autumn, they should feed more animal protein feeds and add a variety of vitamins to the feed to prompt the egg hens to resume egg production as soon as possible. . New layer chickens reared in the spring must also provide more nutritious feed to increase egg production. 3. Increase the light time The natural daylight illumination time is gradually shortened after autumn, and layers should be supplemented with light during laying. When lighting is supplemented, the ground light intensity is preferably 3 lux. Turn on the lights 2 times a day. Turn on the lights until dawn at 4~5 in the first time. Turn on the lights to 20~21 hours in the second dark time. Turn on the lights during the cloudy days. 4. Forced moulting Moulting moulting can promote simultaneous moulting of laying hens and production at the same time. Artificial forced moulting can be done by adding 2.5% zinc oxide or 4% zinc sulfate to the layer's diet. During the feeding of high-zinc diets, water is kept on, and the light can be reduced to 6 to 8 hours per day. 5. Insecticide in a timely manner is the best time for laying worms in the laying hens, and levamisole hydrochloride and quercitrine can be used for deworming.
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.

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.
