How many days does it take to raise grasshoppers before they can be marketed?Grasshoppers grow very fast and can come out in 20 days. 3. Can you please give me a detailed guide on how to raise grasshoppers?2. Construction of breeding shed Grasshoppers have the habit of flying, so they must be raised in a shed. The breeding shed should be built in a ventilated and sunny place, and the ground should be 10 cm higher than the surrounding ground for drainage. It is best to use sandy loam that is not easy to clump, so as to facilitate the picking of grasshopper eggs. Plant monocotyledonous plants such as wheat or corn in the breeding shed for grasshoppers to eat. Every 10,000 grasshoppers requires an area of 15 square meters. You can use the vacant space inside and outside the yard to build the support of the shed with angle iron or wooden sticks, bamboo poles, bamboo strips, etc. According to the size of the shed, use a gauze to make a shed cover, bury the bottom edge in the ground, and leave a door. Install a zipper at the door to prevent grasshoppers from escaping. The height of the shed is 1.5 meters to 2 meters, and the outside of the shed can be covered with plastic film to prevent rain and keep warm. The shed must be built before the end of April. 3. Breeding and management The starting temperature for grasshopper development is 15℃, the highest temperature for development is 40℃, the suitable temperature for development is 25℃~32℃, the relative humidity of the air is 85%~92%, and the moisture content of the soil is 15%~18%. If the temperature is lower than 14℃ or higher than 40℃, grasshoppers will stop eating and die. Grasshopper eggs hatch when the temperature is 28℃~30℃. First, prepare non-toxic soil and sawdust in a ratio of 1:2 and mix well, with a water content of 20%~30%. Spread 3~5 cm of soil in the container and pat it down, evenly spread the grasshopper eggs on the soil, and cover with 1 cm thick mixed soil. Cover the container with a film and check it once every half a day. After finding the baby grasshoppers, use a soft brush to move them to the food in the shed. Hatching is completed in 10~15 days. Baby grasshoppers like to eat fresh and tender monocotyledonous plants such as wheat seedlings, corn seedlings, and weeds, and their appetite is very small. Grasshoppers aged 1 to 3 should be protected from rain. They grow into adults at 27~35 days old. During this period, they shed their skin once every 5~7 days, for a total of 5 times. Each grasshopper lays 70~100 eggs. Grasshoppers like to live in groups and migrate in order to feed, reproduce and lay eggs. Therefore, grasshoppers should be properly disturbed from the time they emerge to before they lay eggs, so that they can migrate in the shed to increase the number and quality of eggs. The eggs should be covered with wheat bran, weeds, etc. before freezing to keep them warm and moist. Adult grasshoppers should be sold in time if they are not used for breeding. Beginner breeders can purchase breeding grasshoppers or eggs from farms (households). Grasshoppers are a special breed, and breeding should be done with caution if there are no orders and reliable sales channels. 4. Can’t sell farmed grasshoppers?Grasshoppers can be raised and sold. Grasshoppers are mainly composed of high protein, and they are a pure natural and pollution-free food. Many places have the custom of eating grasshoppers, so grasshoppers can be raised and sold. 5. When will artificially bred grasshoppers be available?About 40 days, The grasshopper breeding cycle is generally about 40 days, and four batches can be raised in a year. In addition, the suitable temperature for grasshopper development is 25℃-32℃, relative humidity is 85%-92%, and soil moisture content is 15%-18%. When the temperature is lower than 14℃ or higher than 40℃, grasshoppers will gradually stop eating and die. The minimum temperature for hatching eggs is 17 degrees Celsius, the suitable temperature for development is between 26-32 degrees Celsius, and the highest hatching rate is when the soil moisture content is 18-22%. It usually takes 50-60 minutes for the entire egg mass to hatch from the beginning to the end, and the maximum hatching time is from 8 am to 1 pm. There are also differences in the order of emergence during the hatching process. |
