Pests harm plants, causing great losses to agricultural production. After careful study and repeated trials, some people found a cheap, cost-effective, simple and easy way to treat living insects with dead insects. The method is: After capturing some pests, dilute with water and dilute them with water, and spray them on the plants that are damaged by the same pests. The live insects will all die. For example, if 100 g of armyworm is caught, minced and diluted with appropriate amount of water and filtered, then 60-80 kg of water is added to the filtrate, and then sprayed on the rice where the armyworm occurs. The armyworm will die in large numbers and even disappear. Catch or collect dead insects such as cabbage caterpillars 100 grams from the field, grind them to rot, add 200 ml of water, soak for 24 hours, filter out worms, add 40 kilograms of water, and add 50 g of detergent and mix well. This dilution is sprayed on crops such as vegetables where the same kind of pests occur. According to reports, using this method to control cabbage caterpillars, tigers, armyworms, tapeworms and other pests, the effect is very satisfactory. Why can dead pests kill and live pests? Originally, pests were riddled with germs, viruses, and other pathogens. After spraying a diluted solution of dead insect pests on living pests, the pathogens would spread, causing live pests to become infected. At the same time, after spraying the solution of dead pests, the smell of this pest in the field is more concentrated, which attracts a large number of natural enemies to kill. In addition, dead pests also produce a volatile substance called a terrorist hormone that can be terrorized by similar insect pests. The result is not to be starved to death by intimidation, or to death by infection.
