Golden cicada, commonly known as cicada, cicada pupa naturally counts as grasshopper, tree-climbing monkey, cicada turtle, cicada monkey and so on. , belonging to HOMOPTERA, Cicadae.
Habits of Cicada: Cicada usually completes its first generation in 3-5 years, but it is also reported that it completes its first generation in 5-6 years or 12- 13 years. The egg mass overwinters in young branches and plant roots of the same year or two years old in the soil where nymphs of all ages are concentrated, that is, there are two kinds of overwintering insects: eggs and eggs. Overwintering eggs began to hatch in the middle of the following year and ended in late June. Most eggs hatch in the day and afternoon, accounting for about 80%, and fewer eggs hatch at night, accounting for about 20%. The egg period is close to 300 days. The activity of overwintering nymphs is greatly influenced by ground temperature and host plants. When the temperature is higher than 10℃ to 15℃, the sap of the tree begins to flow, and the overwintering nymph begins to move and suck the juice.
Nymphs hatched by overwintering eggs dive into the soil and suck juice at the roots of parasitic plants, with little activity. With the growth of age, earth chambers of different sizes and shapes were built to live in. The outer surface of the earth chamber was rough, the inner wall was smooth and wet, and some walls were attached to the roots of plants for feeding. After autumn, when the temperature drops, it burrows into deep soil for the winter, and after spring, it migrates upward and moves near the roots. In a year, the number of nymphs in the soil is the highest in May. At this time, a large number of wintering eggs hatch into the soil, and the last nymph will soon be unearthed and shed into an adult.
After completing the whole life course of nymphs in the soil, mature nymphs emerge from the soil from late May to mid-late August and crawl to shrub branches and weed stems. , and fixed on the bark branch with claws and front leg thorns, molting and feathering into adults. Oviposition began in late June, with the peak of adult oviposition from late June to late August and the end of oviposition from early September to early June 10. Adult final period165438+1early October. That is, the spawning period of adults can last from late June to early June of 10.
Adults appear at 8- 10 at night and at 4-6 in the morning, and the male-female ratio is basically maintained at 1: 1. Adults often inhabit the branches of tree trunks and have the habit of putting out fires at night. Adults lay eggs on biennial branches with a thickness of 2-7 mm, and the eggs are laid in the xylem of the branches. Nests are closely connected, mostly in a single row, but also in multiple rows, which are arranged in a straight line, and a few are curved or spiral. Each nest lays 6-8 eggs, one spawning branch 12-479 eggs, generally 20-200 eggs, with an average of 146 eggs. Each branch has 6- 146 ovules. There are more than 500- 1000 eggs in the abdomen of each female worm, with a maximum of 1500 eggs and a minimum of 20 eggs, with an average of 800 eggs. Adults are about 3 months old, and the occurrence period is usually from July to September every year. Adults can fly with wings and suck nutrient solution from young branches of trees by sucking mouthparts. Before laying eggs, the mated females insert them into the xylem of the tender branches of the current year one or two years before laying eggs. At the same time, the shoots are dehydrated, withered and dead, which is harmful to trees. Grasshoppers like soft wood and juicy trees, such as hawthorn, peach tree, apple and elm.
The golden cicada was born in the treetops, lived in the soil and grew by sucking the juice from the roots of plants. Set the essence of heaven and earth, which lasted for several years. The newly unearthed cicada pupa has the highest nutritional value, including protein 58.58%, fat 10.23%, total potassium 0.3%, total phosphorus 0.58%, calcium 16.8mg and zinc 82.2mg, far superior to cattle, sheep, pigs, chickens, ducks, geese and fish. It is a rare natural product.
Besides edible value, grasshoppers also have medicinal functions. When the mature nymph of cicada idu becomes an adult, the shed shell is called cicada slough, also known as "cicada slough" or cicada skin. Its main components are chitin and protein, which are sweet, salty and cold. Guifei Liver Meridian is an important Chinese medicine for clearing away heart-fire and relieving exterior syndrome. The fresh and tender nymphs and adults of locusts, especially nymphs, are not only nutritious and delicious, but also have high medicinal value, and are top-grade medicinal diets.
As we all know, golden cicada is a pure natural, pollution-free green wild insect (artificially raised golden cicada only shortens the early incubation time, and the whole growth process is still completely wild, with the same nutritional components as wild golden cicada), which is not affected by feed additives, pesticides and hormones and is high in protein and low in fat. Many consumers are rushing to buy because of this, and the price is also rising year by year. All restaurants, hotels and frozen food factories will come to purchase goods. -copied from "Huangshan Golden Cicada Breeding Base" in www.hsjcyz.com.
