When the temperature reaches 28 to 30°C, the eggs of the leech start to hatch. Prepare non-toxic soil and sawdust powder to stir 1:2. The water content is 20% to 30%. Shop 3 to 5 centimeters of soil in the vessel. , and then the grasshopper eggs on the soil, covered with about 1 cm thick mixed soil. Finally, the container is covered with a layer of film, checked once every half-day, and after the small grasshopper is found, it is brushed onto the food in the shed with a soft brush, and a small grasshopper is hatched after 10 to 15 days. The newly emerged grasshopper eats fresh wheat seedlings, corn seedlings, weeds and other monocotyledons, but the food intake is very small. 1 to 3 years old leech should pay attention to rain, leech from the unearthed to adult about 27 to 35 days, this period every 5 to 7 days, 1 times the skin, a total of 5 times; 5 grasshopper after the gradual start Mating eggs, each leech about 70 to 100 eggs. In order to feed and reproduce the eggs, the grasshoppers like to live in groups and migrate. Therefore, after the emergence of the grasshoppers, they should be given appropriate disturbances before spawning to allow them to migrate in order to increase the quantity and quality of spawning.
