1. Construction of locust breeding sheds and arranging of sheds Before the construction of sheds, ants and crickets on the ground are first cleaned up, and trapped, trapped, and fired, etc. are used. These types of animals are natural enemies of locusts and can prey on locusts. Destroy the eggs, so these animals must not be allowed in the shed. The floor of the shed is 10-15 cm higher than the surrounding ground, in order to facilitate drainage during the rainy season. Sandy loam is best used for soil. This soil is not easy to be agglomerated, and it is easy to spawn and pick eggs. It is planted on the ground to plant single-leaf crops such as wheat.
The construction area of ​​the shed is determined according to the number of breeding locusts, raising 10,000 and using only 15 square meters. The vacant places inside and outside the hospital can be used, and iron, big sticks, and bamboo pieces can be used to construct a shed support according to their own conditions. . According to the size of the scaffolding, a mosquito net-like tent covered with cold cloth was hung on the scaffold and the bottom was buried in the ground, leaving the doorway and a zip at the entrance. This device was designed to prevent the locusts from running. Out and easy to enter the shed for feeding and management. The height of the shed can be 1.5 to 2 meters. In order to keep warm or prevent rain, the shed can be covered with plastic sheeting. When the temperature is high and the locusts are relatively large (above the third age), they are not afraid of rain and may not cover plastic sheets. If the use of natural conditions for fly fleas, the construction of sheds must be completed by the end of April. Choose a sunny place.
2. The hatching and management of Hida eggs can be hatched when the temperature reaches 25 to 30°C, and the natural temperature will arrive in early May. Prepare non-toxic soil first, sawdust 2:1, moisture content 10-15%, store 2 to 3 centimeters of utensils, place the eggs on the soil, cover the eggs with 1 cm thick soil, and then on the utensils Upper film. Check once every half-day and after finding the cubs, use a soft-bristled brush to transfer the larvae to the food in the shed. After 12 to 15 days of incubation, all pups hatched. The young cubs like to eat fresh wheat seedlings,
Corn seedlings, weeds and other monocotyledons, but the food intake is small, 1 ~ 3 cubs should pay attention to rain. The best temperature can be controlled between 25 ~ 30 °C, light in more than 12 hours, the humidity to maintain about 15%, because in this condition the most active aphids, like to eat, is conducive to growth. The three-year-old Feifei likes to live in groups.
3. Feeding and management of adults over 3 years of age to adults The young pups take off the skin 5 to 7 days after spawning. Once the skin is removed, it is a first-year old, strong peeling fast, weak peeling slow, and unearthed during the incubation process. Minute. More than three years of age fly very fast, food gradually increased. At this point, we must ensure that there are enough foods in the shed. First of all, the worms will not affect their normal growth. In addition, there will be strong eating and weak eating, especially if the worms that are being peeled off cannot move, the physique is very soft, and there is a danger of being bitten by eating. More than three instar aphids can be added wheat bran. 1 to 2 days to clear the shed, keep the shed clean. After five rounds of peeling, the aphid grows into an adult. This time is about June 15th. After 10 to 15 days, the migratory locust enters mature sexual maturity and begins to mate. At this time, the migratory locust is very fat. Some locusts are spawned, others can be sold on the market, and the time is appropriate at the beginning of July.
4. Management before and after spawning of migratory locusts After copulation, the abdomen gradually became thick and long, yellow and brown darkened, and the male pheasant was bright yellow. At this time, the ground of the shed should be neatly made and photographed so as to facilitate the spawning of the female crickets, such as the sheds flying in the shed. For spawning concentration, the occupants can use the plastic tarpaulin to cover some of the ground, so as to facilitate the retrieval of eggs in the future. Part of the ground under the sun, as the spawning area. The humidity in the shed is maintained at about 15%. At this time, the worms have a large amount of food and should be supplied in full. The females began spawning around July 10, and the female ovipositor was short and curved, and two pairs of hard spawning flaps were used to lay eggs in the soil. While spawning, it secretes a jelly liquid, forms a protective layer of water resistance on the outside of the egg after solidification, and surrounds the egg into an egg mass to protect the egg from overwintering.
The egg mass of the East Asian corniculturist is brown, slightly cylindrical, slightly curved in the middle and generally 40 to 70 mm long. Each quail egg has 35 to 90 granules of egg, and a very small number of more than 100. This is Xia Xi. The quail eggs are produced in the soil inside the shed and used to hatch the eggs of the second generation of “Autumn Grasshopperâ€. They can not be moved in the shed. When the temperature, humidity, light and other conditions reach the hatching conditions, the second generation of autumn quail cubs will naturally Unearthed, time is around July 20-25, ready to sell or temporarily not used for the second generation of quail eggs, should be promptly removed, with a humidity of 10 to 15% of the soil, an earth layer of eggs, the last layer is The soil is installed in large cans, sealed and placed in a 5-degree refrigerator. The feeding conditions before and after spawning are basically the same as those of the third-instar aphids. The difference is that the light should be up to 16 hours a day. The feed should be sufficient and some more concentrated feed should be added.
The overwintering management of the quail eggs is very simple. We can let the quail eggs in the shed live in the field for the winter. After the winter, the locust breeding area will be covered with some weeds, which can serve as a heat preservation purpose.
About breeding technology of locust
Oriental migratory locusts are Orthoptera, Orthoptera, and Polygonidae. According to statistics, there are 223 genus and 859 species of Smilax. It is one of the better varieties of locusts. Oriental migratory locusts are stout, have a wide range of feeding habits, and have strong adaptability. After hatching into pups, they can be adults after 35 days of feeding, and can be sold after 50 days of fattening. The East Asian cornfielder has a wide range of food intake. Like feeding sheep, he likes to eat reeds, thatch, pennisetum, Lianliancao and Pancao. Feifei does not like to eat grassy corn, wheat, sorghum, millet and so on. When collecting food for fly hoppers, great care must be taken to avoid foods with pesticides. If you are not sure about the collected food, you can wash it in water and feed it. In addition, it is necessary to pay attention and remind that the origins of the first-time households can be purchased from the farms or farmers, and both leech and eggs can be introduced. Special reminder: The grasshopper is a special breed, and it should be prudent when there is no order and reliable sales.
