The feeding of Unicorns is very simple, as long as you prepare a pet box of suitable size, put a pair of Unicorns into the humus with decaying leaves and organic matter, add a rotten wood for Unicorns to perch on for mating, and feed them fruits or jellies, then you will have Unicorn babies born soon. Generally speaking, the life history process of Coleoptera insects belongs to "complete metamorphosis", that is, they must go through four stages: egg, larval stage, pupal stage and adult stage, and each year is one generation. The larvae of Unicorn Fairy feed on the organic matter in the soil. As the age increases, the larvae eat more and more, and the final instar larvae are almost as thick as an adult's thumb. The construction of the cage is mostly made of wood, generally 80cm×60cm×100cm, surrounded by iron or copper yarn, the lower part of the cage is made of white iron with a drawer of 79cm×59cm×30cm, and the top of the cage is made of a live cover, which is easy to change the food, and such a specifications of the cage can be used to raise 50 pairs of Unicorn Fairy. Adult rearing The captured unicorn fairy, quickly put into the cage beforehand to feed, feeding cage below the tin drawer to put 10cm of soil (for larvae pupation), in the soil on top of the larval feed for adult spawning and larvae to feed on, in the cage to put a feed tray, the tray to put some watermelon rinds or pumpkin slices for adult feeding on, generally captured in August unicorn fairy, can be day and night large numbers of spawnings, to the middle of November, the larvae reached 3 age, the larvae to the third age, the larvae to the third age, the larvae to the third age, the larvae to the third age, the larvae to the third age, the larva to the third age, the larvae to the third age. In the middle of November, the larvae reach the age of 3, and can be soaked into commodities for sale. Larvae rearing Compost breeding method: in the field or field with 50% of the weeds, 50% of the wood chips, mixed heap growth 5 to 10m, wide unicorn fairy pictures (5) 1 to 3m, high 1m or so, and then watered, and covered with plastic paper tightly, so that its fermentation, generally wait until there is no temperature inside the compost can be fermented mixture of temperature is basically constant, the unicorn fairy larvae reside in the compost, you can accelerate the growth of this method is a simple and easy way for every farmer. This method is a good way for every farmer to raise the larvae of Unicornia in a simple and easy way. Pool culture method: build a pool on the flat land, the size of each pool varies from 5 to 10m2, 60cm deep, the pool is covered with fermented feed, 50cm thick, and then put the eggs or larvae of Unicorn Fairy, but we should pay attention to the top of the pool should be equipped with rain cover and sunlight shielding equipment. Wooden box breeding method: wooden boards nailed into wooden boxes, the size of the box should be based on the number of larvae rearing Unicorn Fairy, but should not be too large, otherwise it is more difficult to move, before rearing in the wooden box to put a good larval feed, and then put the eggs or larvae into the box, this method is conducive to the stacking of multi-layer and easy to move indoors and outdoors. Winter management Overwintering management of the larvae of Unicorn Fairy: Unicorn Fairy larvae have hibernation habits, generally around the time of frost every year, when the temperature drops to about 10 ℃, Unicorn Fairy larvae activities weakened, feeding is reduced, hibernation signs, with the continuous decline in temperature, the Unicorn Fairy larvae have to enter the winter hibernation, living in groups in the lower layer of the mixture, do not eat and do not move, in the state of dormancy, Unicorn Fairy larvae dormant about half a year or so until the next year, the temperature rise to more than 10 ℃. The larvae will be dormant for about half a year until the following year, when the temperature rises to above 10℃, they will recover and forage for food. Control the temperature of the mixture: measure the amount of cold resistance of an animal called "overcooling point", that is, the animal body fluids can tolerate the critical temperature below 0 ℃ without freezing, due to the unicorn fairy larvae form and structure and biological characteristics of the other animals are different, and at the same time on the ability to resist the cold is also different, according to our preliminary test, the unicorn fairy larvae's According to our preliminary test, the "over-cooling point" of unicorn larvae is at -1℃, that is to say, at -1℃, the body fluids of unicorn larvae will not freeze, and they will not freeze to death in a short time, if the unicorn larvae are under -1℃ for a long period of time, even if the temperature rises back up, the weak ones can not be resuscitated, according to our experiments, the optimal temperature for controlling the unicorn larvae is between 3℃～5℃, and the minimum temperature should not fall down to 5℃, and it should not fall down to 5℃. 5 ℃ between the lowest do not fall below 2 ℃, the highest do not exceed 6 ℃, too high to reach the full dormancy, and will be nutrient consumption, and can not be supplemented easy to die, such as the temperature control in 2 ℃ ~ 6 ℃, the overwintering larvae survival rate of 100%. Mastery of the mixture of dryness and humidity: first of all, we should master the unicorn larvae mixture can not be too dry or too wet, the water content should be controlled between 65% and 67%, too dry to the mixture in time to spray or spray a small amount of water, such as too wet is not conducive to the overwintering of the unicorn fairy. Strengthen the cold-proof measures: 1) In-situ anti-freezing: in the breeding of cages, barrels, boxes, etc., surrounded by straw, and tied with plastic film, appropriate to engage in a few ventilation holes. 2) The over-wintering Unicorn Fairy larvae caught into the altar, and put some of the mixture, and put it in the back of the wind to the sun, moisturizing and anti-freezing. 3) In-situ digging a pool as the Unicorn Fairy larvae winter hibernation holes, holes to put some of the mixture, the size of the holes should be based on the Unicorn Fairy larvae, the size of the hole should be based on the number of how much to decide. 4) The Unicorn Fairy larvae put into a pond as a winter hibernation hole. The size of the hole should be decided according to the number of larvae, and after the larvae are put into the hole, the top is covered with 10cm of straw, which is a very effective method. It should be noted that the winter hibernation hole should be about 50cm deep, should not be too deep or too shallow, and often check whether there is water. Prevent rats from harming: when the unicorn fly larvae enter hibernation, the temperature of the mixture is higher than the outside world, rats like to break in and stir up the hibernation of the overwintering larvae, and even drag away the unicorn fly larvae, and sometimes they will also play holes to settle in it, so in the winter hibernation period of the unicorn fly larvae, we should prevent rats from harming the unicorn fly larvae, first of all, take precautions in the unicorn fly larvae overwintering place to block rats from entering, and also can use the rat traps to trap and kill, and the lead wire cage to trap and block the access of the rats. We can also use rat traps, lead wire cages to trap and block rats from entering and exiting the holes, but we can't use drugs to exterminate rats, in order to prevent the death of unicorn fly larvae from poisoning. Advantages of rearing 1. Less, no risk: the larval feed of the Unicorn Fairy is readily available to the initial decay of various types of weeds, wood chips, etc., almost do not want to invest in any; Unicorn Fairy adults eat some people eat the rest of the watermelon rinds, pumpkin slices, etc., so that the rearing of the Unicorn Fairy is less investment, and there is no risk. 2. Fast results, high profits: generally in August, the capture of the Unicorn Fairy have been mated, can be a large number of spawning, to the middle of November, the larvae up to 3 age, the body is fat, usually into the C-type, about the size of an egg, up to 25-30g, can be made into a commercial gun for sale. Medicinal value of the Unicorn Fairy in addition to ornamental, can also be used in medicine to treat diseases. It is used as a medicine for its male insects, which are captured in summer, scalded to death with boiling water and then dried or dried for spare. In Chinese medicine, it has the function of suppressing fright, breaking blood stasis, relieving pain, attacking poison and laxative. In 1976, some people extracted dicotastin from Dicotyledon, which has certain anticancer effects, with high activity against solid tumor W-256 ulcer tumor and marginal activity against P-388 lymphatic leukemia. Dicotastin is rich in resources and is worth doing in-depth exploration and development.
