In China, edible locusts have a long history. People are accustomed to washing locusts and frying them, sprinkle with salt and pepper powder, etc.; some hotels and guesthouses cook fried locusts on locusts and make delicious foods such as "Flying Storks" and "Land Flying Shrimp"; Aphid deep processing can also be made into canned foods, dehydrated dried products, frozen foods, pickled foods and other flavor foods. At present, the market demand for locusts is more than 100 tons per year, but the yield of artificial breeding locusts is less than 10 tons, and there is still much room for development. Locust farming has low input and large output, and once purchased eggs, it can be used for a long time. The author has been breeding locusts for several years and has developed a set of breeding techniques and experiences for reference by the general insect enthusiasts. First, the early preparation for raising maggots: raise maggots to build breeding sheds. It is advisable to choose a place where the ventilation is sunny. After the house, the idle courtyards and plots can be used. The ground of the breeding shed should be 10 cm to 15 cm above the surrounding ground in order to drain the rainy season. The scaffolding can be constructed with bamboo, bamboo poles, wooden sticks, etc., and then use gauze as a greenhouse cover, the bottom is buried in the ground, leaving a doorway, with a zip lock on the door or sticking . The height of the shed is 1.5 to 2 meters and it must be completed by the end of April. The area of ​​the shed is determined by the number of locusts. Generally, it can raise 600 to 800 adults per square meter. In the beginning, raising 10,000 locusts can be 15 square meters. Each female eel can lay 60 eggs to 90 grains. With the increase in the number of aphids, it will continue to expand the greenhouse. After the cultivation of the greenhouses, the dense wheat plants were planted on the ground in the shed to prepare the larvae for consumption. Second, the management of locusts: first prepare non-toxic soil, the new sawdust and soil by 2:1 mix well, the water content of 20% to 30%, in the appliance or board shop 3 cm to 5 cm thick, eggs and then covered 1 cm thick soil. After 10 to 15 days of incubation, before and after the "May 1st", the locusts can all be hatched. After hatching, the pups dehydrated the skin 7 days later, removed the skin once for 1 year, removed the skin 5 times and became adults, and 50 days later, the adults could be sold (500 to 700 per kg of aphids) or Keep spawning. In the 1st to 3rd instars, the larvae feed intake is very small. After 35 days, the feed intake is doubled. In addition to collecting part of wild weeds, it is also possible to harvest artificially cultivated Mexican jade feed. Hey. Third, culture locust precautions: 1. Aphid feeding time in the morning 9:00 to 5:00, 2 to 3 times a day. When feeding aphids, evenly spread the forage in the shed. 2. Rainy weather should cover the breeding shed, because the ground is too humid and locusts will die without eating. 3. The density of feeding is generally 600 to 800 per square meter. It is advisable to raise the density of strong food, eating small foods, or being scavenged and being eaten. 4. When the summer temperature is above 35°C, the culture shed must be shaded, and some water should be sprinkled on the gauze net or shed to supply water. If the shed is too dry, it will cause locusts to die. 5. If the locust eats poisoned forage, it will die immediately. So if you do not know if the forage is poisonous, it is best to wash it before feeding. 6 The life cycle of aphids is 75 days. Females will normally die after they have laid eggs. Males will die normally after mating. Fourth, the relevant knowledge: locusts a year in the summer and autumn. From the beginning of May to the beginning of July, it grows into a clam and lays its eggs in the shed to complete the first generation. From July 15 to 25, the second generation locust, namely the “Autumn Grasshopper†will be naturally unearthed until the beginning of September. Spawning in the ground and then dying of the eggs can naturally overwinter. Until the coming May 1st, young cubs will naturally hatch as the temperature gets warmer and come out.
