Liang Tao of Shinan Town, Xingye County, Guangxi, stocked turkeys in his contracted and cultivated 40-acre citrus grove. Because of its strong herbivorous power, high food intake, and high urinary excretion, his citrus garden is not used throughout the year. For weeding, the amount of fertilization was also reduced by one-third. Citrus trees grew normally, fruiting smoothly, fruiting, and vigorous tree vigor. After a large number of flowering results, the fruits did not decline, and the fruits grew well, the size was uniform, and the color was bright.
Because of the large amount of feces excreted by herbivorous turkeys, the high content of organic matter and trace elements is indispensable for the growth and development of citrus. It has a significant role in promoting the growth and flowering of citrus trees.
It is understood that stocking turkeys in citrus orchards can be stocked in three batches each year. Each batch of orchards can stock 15 to 20 plumages. If they are too few, they cannot completely eat the weeds, and the excreted feces cannot satisfy the growth and development of fruit trees. Needs; too much, the weeds in the orchard are not enough for turkey to eat, affect the normal growth of turkeys, and even if they do not have enough weeds to feed on the leaves of fruit trees, it will affect the normal growth of fruit trees.
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.
