Many crop pests have characteristics such as greenness, yellowing, phototaxis, and odor. Use these characteristics of pests, take the appropriate method to seduce, you can get together and kill it, destroy it before the oviposition hazard. The worms of the insect pests such as cotton aphids and bridge-building insects on the moth-repelling cotton larvae have tropism. These worms inhabit green groves during the period of March-April each year until they lay eggs, and they come out at night. You can use a willow branch to tie it, use a small wooden stick or bamboo stick about 1 meter long to insert it in the wheat field, and lure it to focus on the branches to hide it. In the morning, use a plastic bag to cover the branches, and then shake and collect the moths. To be eliminated. Need to insert 5-10 per acre. In the cotton growing season, insecticide moths can also be inserted into cotton fields. The grass attracts adult moths like the wheat armyworm and prefers to lay eggs on yellow withered grass. Using this feature, in April of each year, the rice straw is bundled into a bowl-shaped, long, 30-cm straw handle, tied to one end of a small wooden stick about 1 meter long, and the other end is inserted into a wheat field, inserting 5-10 sticks per mu. The moth can be trapped on the grass to spawn. Usually after 5-7 days, the grass handle is collected and burned, which is the effect of killing eggs and preventing insects. The light attracts the moth law rice locust, rice borer and other adult, at night is very sensitive to the light, once sees the light will fly to the light. Before the peak of emergence of these insects and before the moth lays eggs, use a washbasin to fill the water every night, add a few drops of kerosene or diesel to the water, place it on the rice field stems, and place a lamp in the pot. When the moth sees light, it will fall into the water. Each insect kills 4-6 nights. Adults such as the cotton ground tiger and Spodoptera litura by the Syrup Moth method have extremely strong taste sensation and are sensitive to acid and sweet taste. Using this feature, sweet and sour liquids can be formulated to trap these pests. From March to March each year, a solution is prepared at a ratio of 500 ml of water, 50 grams of brown sugar, 250 ml of vinegar, 50 ml of wine, and 40 ml of 80% dichlorvos. Use three small wooden sticks about 1 meter long to form a tripod rack in the middle of the field, place the pots or pots and other utensils on the tripod, and then pour the sweet and sour liquid into the container. Five. The moth moths smoked after smelling the odor of syrup and fell into the pot and died of poisoning. Place the pots every evening and harvest moths in the morning and kill them for 3-5 consecutive days.
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.

There are tricks to lure crop pests
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.
