How do locusts manage?

Construction of locust breeding shed

The breeding shed should be built in a ventilated and sunny place, the ground of the shed should be about 10 centimeters higher than the surrounding ground to facilitate drainage, the soil had better be sandy loam to facilitate the laying of locust eggs, and grow Monocotyledon plants such as wheat or corn on the shed ground to prepare for locusts to eat. The construction area should be determined according to the number of locusts, and it takes about 15 square meters for every 10,000 locusts. Angle iron, wooden sticks and other supports are used to build the shed, and then according to the size of the shed, the screen is used to make the shed. The bottom edge is buried in the ground, leaving the door with a zipper to prevent locusts from running out and people from getting in and out of the shed. The height of the shed is 1.5 to 2 meters. For heat preservation and rain protection, plastic sheeting can be covered outside the shed. To raise locusts under natural conditions, the construction of the shed must be completed by the end of April.

Feeding and management of locusts

The suitable development temperature of locusts is 2532 ℃, the relative humidity is 85% 92%, and the soil water content is 15% 18%. When the locusts are less than 14 ℃ or higher than 40 ℃, locusts gradually stop feeding and die. When the temperature reaches 2830 ℃, locust eggs begin to hatch, first prepare non-toxic soil and sawdust according to 1 ∶ 2 mixing, water content of 20% 30%, spread 3-5 cm of soil in utensils, and then spread locust eggs on the soil, cover with about 1 cm thick mixed soil. Finally, the utensils were covered with a film and checked every half day. When small locusts were found, they were brushed onto the food in the shed with a soft brush. After 10 to 15 days, the small locusts hatched.

Newly unearthed locusts like to eat fresh and tender wheat seedlings, corn seedlings, weeds and other monocotyledonous plants, but the food intake is very small. Locusts at the age of 1 and 3 should pay attention to rain protection. It takes about 27 to 35 days from unearthed to adult, and during this period, locusts molt once every 5 to 7 days for a total of 5 times. Locusts after 5 years old gradually begin to mate and lay eggs, and each locust lays about 70 eggs. In order to feed and reproduce eggs, locusts like to live in groups and migrate, so locusts should be given appropriate interference from Eclosion to before spawning, so as to improve the quantity and quality of eggs. Before freezing, the eggs laid should be covered with some wheat bran, weeds and other heat preservation and moisturizing to prevent frost cracking. Adult locusts during the growing period should be sold in time if they are not seeded.
