Guo Guo, called "Ge", belongs to Orthoptera, Tettigonidae. Produced in Hebei, An Wei, Shandong, Shaanxi and other places. It is about 4 cm long and nearly 1 cm wide. It has a strong body and a green body. Due to different producing areas, the colors range from light green to dark green. The head has tawny, slender filiform antennae, which is one of its sensory organs. Strong hind feet, big belly and good at jumping. Born in the grass, bushes and bushes in Yuan Ye, it usually hides in the grass or crawls and lives, and feeds on plant stems. It mainly eats the stems, leaves and fruits of plants, and has a large appetite, which is one of the pests that harm crops. But because of its good singing, farmers caught it and put it in cages to sell in cities, which was very popular with citizens, especially children.

First, the variety of fruit:

The varieties of fruit are Jingtie fruit, Tianjin green fruit, Sanqing fruit and white grass fruit.

Second, artificially assisted egg retrieval and incubation:

1. Take the egg:

(1) Artificial egg retrieval: select large and robust male and female slugs, put them in clay pots, and cover them with gauze. The ratio of male to female is 2: 1 or 3: 1, that is, two or three females are matched with one male. The total number of slugs in the basin should not be too much. If crowded, it is not good for mating. If the male bird is fed in time every day, when he meets the male and female, the male bird will flap his wings and sing "playing the piano", and the female bird will reciprocate and mate soon. About two weeks after mating, females begin to lay eggs. Eggs laid before mid-July can hatch nymphs in the current year, while eggs laid after mid-July are difficult to hatch nymphs in the current year, so they can be reserved for hatching in the next year. Among the slugs introduced into the producing area at the end of June, if two or three hundred female slugs are introduced at a time and more than one hundred male slugs are added, tens of thousands of eggs can be laid.

(2) Egg screening and egg separation: after laying eggs, gently break the sand in the clay pot, screen out the eggs with a basket, wash them with clear water and dry them, and then prepare to lay eggs. Choose a clay pot with a height of 15cm and a diameter of 20-25cm, and re-release the sterilized sand. The soil-sand ratio is still 65,438. Do not overlap, but cover the eggs with fine sand with a thickness of 4-5 cm, and then spray water on the soil, and the relative humidity of the soil is about 70%. Finally, cover the spout with a cloth and tie it tightly with a rope.

2. Artificial incubation:

(1) Artificial incubation of eggs: Put the clay pot with eggs in the sun, that is, "long eyes". Keep the soil temperature at about 30℃. Generally, in July and August, when the sun is too strong, objects should be used to shade the sun to prevent the soil temperature from being too high. Spray water into the basin in time every day to keep the soil moist. It can be heated for more than 10 hour during the day and exposed to night dew outdoors at night. By mid-September, when the temperature is lower than 22℃ at night, the egg basin should be moved into the greenhouse to continue heating and kept at 30℃ during the day. Store at 25℃ at night. A month later, a pair of dark circles appeared on both sides of the middle. Two months later, the egg swelled and thickened obviously, the eyes gradually moved out of one end of the egg, and the distance between the two eye points also narrowed. One end of the eye point will develop into a head, and the other end will gradually turn green from tan. This end is the nymph's tail. After two and a half months, all the rapidly developing eggs turned green, and the transverse abdomen and six feet on the nymph's back were faintly visible.

(2) Incubation: When the slug embryo is fully mature, the nymph will break out of its shell. Before the egg leaves the eggshell, the nymph will move gently in the egg. At this time, the eggshell has become very thin and soft. Under the constant peristalsis of nymphs, one end with pores will break. If the worm sticks out its head first and then its forelimbs, the eggshell will come off behind the worm like a skirt. The newly hatched nymphs are emerald green, and the unearthed larvae take a break and start crawling around. At this time, the nymph can be moved to the insect cage and raised separately. When the newly hatched nymph is moved into the insect cage, the feather brush made of bamboo sticks should be tied with the long feathers on the wings of geese or pigeons, the pot should be tilted to the mouth of the insect cage, the nymph should be gently swept into the cage, and then the cage mouth should be covered.

Three, nymph feeding management:

1. Preparation before feeding: First, prepare insect cages and trays. Soak in potassium permanganate solution for disinfection, and then rinse the solution with water to ensure cleanliness and sterility. The floor, walls, doors, windows and roofs of insect houses should be strictly disinfected with potassium permanganate and flame sprayers for later use. After disinfection, install heating facilities in the insect house for standby, and heat the temperature and humidity in the insect house in advance after the estimated incubation time to meet the requirements of hatching nymphs.

2. Temperature, humidity and ventilation management:

Newly hatched nymphs are very strict about temperature. The temperature should be controlled at around 28℃, not too high. Nymphs above the third instar have strong adaptability to temperature changes, generally at 25-28℃, with higher temperature, shorter molting interval and faster development, but less robust constitution, lower temperature, longer molting interval, slower development and stronger cold resistance. Strong physique, that is, the so-called "hot slough" and "cold slough". You should choose "cold flow" management. The temperature difference between day and night is also large, which can be controlled at about 5℃. Insects like to be dry and generally don't need to spray a little water to cool down.

If the insect is afraid of sultry heat, it should cooperate with the greenhouse to cool down and open the window regularly for ventilation, and choose to open the window for ventilation when the temperature is the highest around noon every day. When the indoor temperature does not drop to the minimum, the ventilation time should be extended as much as possible. The air in the greenhouse should be fresh to prevent the invasion of smoke, wine, spices, cosmetics and other smells, so as to avoid nymph being affected.

3. Feed and feeding: There are three main kinds of feed for feeding slugs, namely soybean (or green beans), sheep liver and carrot. Soybean contains a high content of plant protein, which is more than 36 grams per 100 grams. Sheep liver contains a high content of vitamin A, among which carrots and crude fiber have excellent defecation function besides comprehensive nutrition. It is indispensable for nymphs. Mix 2 parts of soybean, 2 parts of carrot, 1 part of sheep liver and a small bag of dry yeast, and grind them into mud with a meat grinder. When feeding, cut the fresh Chinese cabbage leaves into blocks, coat the twisted feed on them and put them in the jar. A few more pieces can be put in a jar, up and down, so that nymphs can eat. Because nymphs eat a small amount of food, don't draw each piece too thick to avoid wasting it. Keep food fresh every day. Now feed it. Don't feed it every other day. Feed regularly, once a day 1 time, twice is better.

4. Cage changing and management during the big sheath period: With the increase of molting times and the growth of nymph size, it is necessary to change from small cage to large cage in time to prevent nymph from moving in the small cage and affecting molting, movement and growth and development. In the cage, put the millet broken off from the sorghum stalk for it to inhabit and jump.

The last molting of the slug is commonly called "big sheath", and the height of the feeding trough in the big sheath period should be 2-3 times of the slug's body length, so that the molted new body has more room for maneuver. Branches and sorghum stalks usually placed in the pot should be taken out, and T-frames or tripods made of the pulp of sorghum stalks should be put back into the pot, with the top of the frame slightly lower than the mouth of the pot, so as to shed their skins. When molting, the slug climbs to the height of the scaffold and hangs upside down on the pulp of sorghum stalk. Six feet and claw flowers can be sandwiched in the pulp, which is very reliable. Slugs kept in sarong don't need to stand up. Slugs are strong when they catch the cage wall, and generally don't fall off. When molting, the new body falls off upside down under the action of gravity. Don't panic when molting, and don't make a loud noise and vibration, so as not to let slugs fall. If an individual falls off the bar and his hind limbs bend, the bent leg joints can be slowly straightened in 5 minutes. If you wait a little longer, your limbs will harden, so you don't have to worry about "disability". Limbs are soft after molting. Don't disturb them. Let them move naturally. After a few hours, the limbs were completely hardened. Don't feed them yet.
