Second, artificial egg retrieval and incubation:
1. Take the eggs:
(1) Artificially assisted retrieval of eggs: Select large and robust male and female crickets into pots, covered with gauze covers, male to female ratio of 2:1 or 3:1, ie 2, 3 females with one male . The total number of cockroaches in the pot should not be too large. If it is overcrowded, it will be unfavorable to mating. Daily feeding will be timely and male-female will meet. The male will flap its wings to sing "playing the piano" and the females will be mated and reported quickly. About two weeks after mating, the females begin spawning. Eggs produced before mid-July can hatch nymphs that year, and eggs produced after mid-July can hardly hatch nymphs in the year and can be left for next year's incubation. At the end of June, the oysters introduced into the production area will be able to produce tens of thousands of eggs at a time if they introduce two or three hundred females and one hundred more males.
(2) Screen eggs and laying eggs: After spawning, the sandy soil in the tile pots will be broken gently, and the eggs will be sieved out with quail, rinsed with water to dry, and then prepare eggs, choose a height of 15 cm, caliber For 20-25 cm about the basin re-released toxic sandy soil, soil and sand ratio still can be 1:1, you can also use only fine sand, 5-6 cm thick, evenly spread the eggs in the soil On the egg, make one grain and one grain evenly, do not stack it, then cover it with a fine sand on the egg. The soil thickness is 4-5 centimeters, and then the water is sprayed onto the soil. The relative humidity of the soil is about 70%. Finally cover the mouth with a cloth and tie it with a rope.
2. Artificial incubation:
(1) Artificial incubation of eggs: The pots and pans that lay eggs are exposed to sunlight, ie "long eyes". Keep the soil temperature at about 30°C. Generally, in July and August, when the sunlight is too strong, we must shade the object to prevent the soil temperature from being too high. Sprinkle water in the basin in time to keep it moist. During the day, it can be heated for more than 10 hours, and in the evening it is exposed to outdoor dew exposure. By mid-September, when the nighttime temperature is lower than 22°C, the pelvis should be moved into the warm room to continue warming and kept at 30°C during the day. Stay at 25°C during the night. A month later, a pair of black eye spots appeared on both sides of the middle. Two months later, the eggs expanded significantly and became thicker. The eye gradually moved out of one end of the egg, and the distance between the two eye points also decreased. One end of the eye will develop into a head and the other end will gradually turn green from yellow-brown, which is the tail of the nymph. After two and a half months, the faster-growing eggs have all become green, and the nymph's dorsal abdomen and six feet have been faintly visible.
(2) Incubation: When the embryo of quail is fully developed, the nymph will break out of the shell. The nymphs will move gently inside the eggs before being hatched. At this time, the egg shells have become very thin and soft. Under the constant creeping of the nymphs, one end of the pores will be broken. When the nymphs first extrude their heads and extend their forelimbs again, the egg shells will come off the back of the body like a skirt. The newly hatched nymph is green and the unearthed larvae take a rest and start crawling and crawling. At this time, the nymphs can be moved to a rearing cage and kept in separate cages. When the newly hatched nymphs are moved into the rearing cages, feathers made from bamboo sticks should be tied with long feathers on the goose or dovetail wings, and the nymphs should be gently swept into the cage by holding the pot leaning at the mouth of the insect cage. In the middle, then cover the cage.
Third, nymph feeding and management:
1. Preparation before feeding: First, prepare a cage and tray. Disinfect with potassium permanganate solution and then flush the solution with water to ensure clean and sterile. The floor, walls, doors, windows, and roofs of the insect rearing rooms should be strictly disinfected with potassium permanganate and a flame sprayer. The disinfection facility of the breeding room is installed after disinfection, and it is estimated that after the hatching time, the temperature will be increased in advance so that the temperature and humidity in the house can reach the requirements of incubation and nymphs.
2. Temperature, humidity and ventilation management:
The temperature of newly hatched nymphs is very strict. The temperature is controlled at about 28°C and the temperature should not be too high. More than three instar nymphs have increased adaptability to temperature changes, generally controlled at 25-28°C, with higher temperature, shorter furrow spacing, and rapid development, but the body is not very robust, and the temperature is low. Some molting intervals are long and development is slower. , strong cold resistance. Strong physique, the so-called "hot" and "cold". Should choose "cold" management. Day and night temperature changes have to be larger, can be controlled at about 5 °C. The nymphs like to dry, made a small amount of water for cooling, generally do not have to spray.
The nymph is afraid of stifling heat, and it is necessary to cooperate with the heating room to cool down and open the windows regularly for ventilation. The window is selected for ventilation at the highest temperature around noon every day. Ventilation time is extended as long as indoor temperature is not reduced to a minimum. The air in the warm room tries to achieve freshness and prevents the intrusion of odors such as smoke, wine, spices and cosmetics to prevent the impact on nymphs.
3. Feed and Feeding: There are three main types of feed for quail feeding: soy beans (or green beans), goat liver, and carrots. Soybeans contain high levels of plant protein, containing more than 36 grams per hundred grams. The goat's liver has a high vitamin A content. Carrots have nutritious and nutritious effects. It is indispensable for nymphs. 2 parts of soybeans, 2 parts of carrots, 1 part of goat livers, and the proportion of dry yeast in a small bag were mixed and ground with a meat grinder. When feeding, fresh cabbage leaves are cut into pieces, and the chopped feed is placed on the top of the jar. In a jar, one can hold a few more pieces, with the upper and lower parts of the can, so that the nymphs can be eaten. Because nymphs eat small, do not apply too thick on each piece to avoid waste. The daily food should be kept fresh, and you should feed it now. Do not feed on the eclipse. Feeding should be done regularly, once a day, and twice.
4. Change cages and sheaths management: With the increase in the number of nymph molting, body shape is getting larger, it is timely to change from a small cage to a large cage to prevent the nymph from moving inside the small cage, affecting the skin, exercise and growth. development. In the cage, the scorpion stalks should be used for their habitat.
The last time the cockroach was commonly referred to as the "large sheath", the height of the raising cans for the large-sheath period should be 2-3 times the length of the cockroaches, giving the new body a greater degree of flexibility. The branches, sorghum stalks, etc., which are usually put into the tanks, are to be taken out. The tee stands or tripods made of sorghum culms are put back into the tanks, and the tops of the stands are slightly lower than the tank mouths, so as to furnish the skins. use. When climbing the skin, it crawls up to the height of the stand, and hangs upside down on the stalks of the sorghum culms with six feet. The claws can be caught in the stalks and are very firm. The crickets that are kept in a cage do not need to be racked. The crickets hold the cage walls and they are strong and generally do not fall out. When the skin is upside down, the new body is pulled out of the sheath by gravity. When you clam skin, you must be frightened by surprise. Do not have big noises and vibrations, so as to avoid falling down. If there is a situation of individual loss, the hind legs will fall and the curved leg section will be straightened within 5 minutes. Wait a moment, limb hardening, so that no "disabled" worry. After the molting is completed, the limb is very soft, can not be disturbed, let it move naturally, and the limb is completely hardened after a few hours. Do not feed it for a while. After one day, remove it from the rearing tank and store it in a gourd or carton for sale.
Its height adjustment,back section adjustment are controlled by remote controller or pedal controller.The low voltage syatem ensures user's safety.Obstetric Delivery Table
