Without blindly taking medicine without analyzing the weather, water quality, temperature, and the condition of the fish, it is very easy to cause fish poisoning and death. Therefore, before using disinfectants and pesticides, we must first pay attention to water quality and water temperature. The occurrence of most fish diseases is related to deterioration of pond water quality. After the disease is found, the water quality must be treated first. If blind medications are used in the event of water quality deterioration or lack of oxygen, it is easy to speed up the condition, and when severe, it will cause flooding. In order to prevent the occurrence of fish poisoning, when the water quality deteriorates or lacks oxygen, external disinfection and pesticides should be prohibited. After the water is treated, apply the drug again. In addition, water temperature is an important factor affecting the toxicity of drugs, the general rule is that the higher the water temperature, the greater the toxicity. However, some insecticides are the opposite, such as avermectin, when the water temperature is low, the toxicity will increase, so the use of such drugs should be appropriately reduced.
If ponds cause heavier poisoning deaths after medication, the following emergency technical measures for mitigating fish poisoning can be taken.
1. Immediately change the amount of water and introduce clean water. At the same time, oxygenating agents or aerators should be used to ensure fresh water and adequate dissolved oxygen. If the poisoning is heavy, the fish should be transferred to a new pond to remove the diseased fish from the poisonous environment. When you discover poisoning, you must not use medicine indiscriminately, otherwise it will increase death.
2. After discovering poisoning, it is necessary to correctly determine the source of the poison and take corrective measures to eliminate the source of the poison. Oxidation, neutralization, precipitation and other measures can be used to eliminate toxic substances that remain in the water and prevent further absorption of poison by fish and shrimp.
3. Ease the symptoms of fish poisoning. The right medicine is prescribed and the medicine is promptly administered to restore various functional disorders caused by poisoning of the fish and restore physiological functions. For poisons that have been absorbed, various drugs for detoxification and enhancement of immunity should be taken in time to reduce the concentration of poisons in the blood, block the effects of poisons, and promote the excretion of poisons.
Insect sex Pheromone as a chemical communication tool during the reproductive stage between allogeneous insects. The high complexity and specificity of its chemical structure is an important guarantee for reproductive isolation between insect species. Therefore, sex pheromones between different insects cannot The replacement will not cause confusion, which has great practical value in the regional investigation of insects, plant quarantine, and trap control.
In nature, adult females will release a compound called sex pheromone after sexual maturity. It is released into the air and diffuses with the airflow. It stimulates the chemosensory organs in the male antennae, causing male sexual impulses and lures. The male flies to the release source and mate with the female adult to reproduce offspring. Therefore, insect sex pheromone products are bionic high-tech products, which release artificial sex pheromone through the core.
Insect sex pheromone is a compound that regulates the attraction of male and female insects. It is sensitive and specific. It has a long distance and strong temptation. The use of this product to attract and kill pests does not contact plants and agricultural products, and there is no concern about pesticide residues. It is one of the first methods for controlling pests in modern agricultural ecology.
Currently the most popular insect sex pheromone varieties are: weevil sex pheromone, Asian corn borer sex pheromone, cotton bollworm sex pheromone, diamondback moth sex pheromone, glutenous sex pheromone, pear horde worm sex pheromone , Codling moth sex pheromone, soybean heartworm sex pheromone, cowpea viburnum sex pheromone, horsetail pine caterpillar pheromone.
