Aphididae are representative species of Polygonaceae insects. Adults are also known as blackbirds. The nymphs are commonly known as turtles. In many parts of our country, there are customs of eating aphids and their nymphs, which are particularly prevalent in Shandong. The most common way of eating is “oil. Fried golden oysters." The nymph (know turtle) has a very high nutritional value and unique taste of the medicinal diet, and it can be considered as a leader in edible insects. Now it has become a famous dish for various occasions. However, due to environmental damage, the deforestation of trees, the living environment of crickets and nymphs (known turtles) were severely damaged, resulting in a sharp decline in the natural production of nymphs (known turtles) year after year, and the market prices have also increased year after year and remained high. Due to the continuous increase in social demand, relying solely on collection, far from meeting market requirements, many localities have begun to shift the way natural resources are collected to artificially large-scale rearing under our guidance. Shannong University Jinchan breeding base promotes Grade A golden larvae and egg branches T18 varieties. The quality and quantity are guaranteed. The survival rate is over 80%. The use of poplars, fruit trees, under the canopy and other trees to raise the leeches quickly does not affect the normal growth of the trees. Can also increase income. Wild gold resources are now exhausted, from May to June the hotel snapped up, the market prices soared. There is a large experimental practice base, to seek breeding bases and large models, to provide eggs, free technical training. Acquisition. Artificial gold aquaculture mainly has the following advantages: (1) Abundant resources: There are a large number of tree resources such as poplars and fruit trees in rural areas. (2) High-quality eggs: The golden quail eggs can be purchased from professional breeding farms. This base supplies golden quail eggs as grade A eggs. Each twig contains 200-500 eggs. It is important to survive mating eggs. The rate is 80% and the wild egg rate is 20%. (3) Shortening the time: Breeding of the breeding time The breeding eggs can be sold for 1.5 to 2 years after breeding. (4) No management: Without the need to feed and feed food, the golden crickets suck up root juice from the soil. (5) High efficiency: 2000 eggs per square meter, each calculated at 0.1-0.2 yuan, 200-400 yuan per square meter of income, if the culture does not affect the growth of trees, the income per mu will also be more than 10,000 yuan. . (6) Best-selling products: Small and large restaurants, hotels, and refrigerated food factories will all come to the market.

Morphological characteristics Adult body length 40 to 48 mm, 125 mm wingspan. All black, shiny, with a metallic luster. Compound eye light auburn. There is a yellow-brown patch on the center of the front edge and on the cheeks. The middle thoracodorsal plate is large, with a tan-colored "X"-shaped ridge in the center. Before and after the wings are transparent. The front wings are yellowish-brown at the front, black at the base, black at the front of the front wing, 1/3 black at the base of the forewings, and the base of the wing is black with a light yellow-brown spot; the base of the hind wings is 2/5 black, and the veins are light yellow and dark black . Feet pale brown. The first and second quarters of the male's abdomen have mas- ters, females have no sirens, there are hearing devices, the ventral valve is not well developed, and ovipositors are prominent and well developed. Eggs long and elliptic, slightly curved; ca. 2.5 mm long and 0.5 mm wide; milky, shiny. The nymph is yellowish-brown, with winged buds, capable of crawling. The forefoot of the first instar is clearly digging; the last-instar nymph is 35 mm in length and yellowish-brown. The front foot is digging and the wing buds are well developed.
The value of economic resources is the value of food. According to scientific analysis, wolfberry is rich in amino acids, proteins and trace elements, and essential amino acids account for 46.63% of total amino acids.
In addition to having food value, it also has medicinal functions. When the mature nymph is changed to adult, the outer shell of the eclosion is called quail, also known as è‰ è‰ â€ or è‰ è‰ , ,. Its main components are chitin and protein, sweet, salty, cold, into the lungs, liver Jing, is an important Xin Liang Jie table Chinese medicine. Fresh nymphs and adult nymphs, especially nymphs are not only nutritious and delicious, but also have very high medicinal value.
The natural habits of crickets are generally completed in 1 to 3 to 5 years, and there are also records of 1 to 5 to 6 years or 12 to 13 years. The overwintering states are nymphs with two different eggs and sizes, and the overwintering sites are divided into two kinds: above ground and below ground. The overwintering states are wintering on young shoots of the same year or two years old and young nymphs of all ages. surroundings.
The wintering eggs begin to hatch in mid-May of the following year, and the incubation period is from late May to early June, and the hatching activities are completed at the end of June. Eggs hatch more during the day and afternoon, accounting for about 80%, and there is less hatching at night, about 20%. The egg period is close to 300 days. The activities of overwintering nymphs are most affected by the temperature and the host plant sap. When the temperature is higher than 10°C-15°C, the sap of the tree begins to flow, and the overwintering nymphs begin to suck and feed.
The nymphs hatched from the wintering eggs (called ants) are immersed in the soil and suck sap at the roots of the host plants, which is less active. As the age grows, earthenware chambers of different sizes and shapes are created and inhabited. The surface of the earth is rough, and the inner wall is smooth and moist. A part of the wall adheres to the root of the plant for feeding. After the fall, the temperature dropped, and the soil was drilled into the deep soil. After spring, it migrated upwards to the activities near the roots. The number of nymphs in the soil in May is the highest in the year. In this case, a large number of overwintering eggs are hatched into the soil, and it is a time when the last-instar nymph is about to emerge into adult moths.
After completing the whole life process of the nymph in the soil, the mature nymphs drilled from the soil from late May to late August, and crawled to shrub branches, weed stems, etc., and fixed to the tree with claws and forefoot stabs. On the branches of the skin, moltings become adult. From mid-June to mid-July, the emergence period of adults is high, and early October is the final period. About 20 days after adult emergence, the oviposition spawned, and spawning began in late June. The end of June to late August was the fecundity of adults, and the end of spawning was from early September to early October. The final stage of the adult is early November. That is, the adult's spawning period can last from late June to early October.
Adults mostly emerged at 8 to 10 o'clock in the night and 4 to 6 o'clock in the morning, and the male to female ratio was maintained at a ratio of 1:1. Adults often inhabit the branches of trees and have the habit of fighting fire at night. Adults spawn in one or two years old, 2 to 7 mm thick branches, the eggs are produced in the xylem branches, nests close together, mostly single, double, straight line, a few curved or spiral . There are 6 to 8 eggs in each nest, and there are 12 to 479 eggs in a spawning branch, usually 20 to 200, and an average of 146 eggs. There are 6 to 146 ovary points on each branch. Each female has more than 500 to 1000 eggs in its abdomen, up to 1500 and at least 20, with an average of 800. Adult life is about 3 months, and the occurrence period is generally from July to September each year. Adults have wings and can fly. They suck on the nutrient sap from the young shoots of trees. After mating, female ovipositors use an ovipositor to insert into the xylem of the first year or two years of mature branches before laying eggs. At the same time, the twigs are dehydrated and dried to death, causing damage to the trees.
As a result of environmental damage and the felling of trees, the living environment of the nymphs has been severely damaged, and excessive human-caused arrests have led to serious depletion of nymphs (known turtles). In terms of demand, the demand for large cities such as Beijing, Shanghai and Guangzhou is more than 100 tons. The market gap is quite large, and the market price is getting higher and higher. The artificial breeding of goldfish has a bright future.
