The answer to your question is as follows:

Eupolyphaga culture technology:

Eupolyphaga Seu Steleophaga, also known as Eupolyphaga Seu Steleophaga, is cold, salty and toxic, and has the functions of promoting lactation, removing blood stasis and relieving pain. It is an important Chinese herbal medicine.

First, the growth and development of Eupolyphaga sinensis can only be accomplished by oviposition, nymph and adult 1 generation. It takes about 3 months for males to mature; Women need about 9 ~ 1 1 month. June ~ 1 October is1week after mating. The egg mass (called the egg sheath) is about 0.5 cm long. Under the condition of 30 ~ 35℃, after 40 ~ 60 days of incubation, the white nymph molts every 20 ~ 50 times10 ~1time.

Second, the feeding equipment

1, toolbox: there are four kinds of screens: 1 The square hole of the No.1 screen is 8.5mm2, and the square hole of the No.3 screen is 3.5mm3, which is similar to the chaff screen; No.4 sieve square eye1.2mm.

2. Feeding pit: the back of the feeding pit should be against the wall, and the area in front of the wall is 3.5 meters long and 0.5 meters wide. Five pits can be built, and the middle of each pit is divided into five layers with cement boards. There are 25 pits, each with an area of 0.33 square meters, and the pit is filled with soil. The front of the pit is divided into two sections, the lower section is cement board and the upper section is wood. When necessary, the upper and lower parts can be removed. Feeding soil can be sand, clay or loam. After the soil is broken, remove large pieces with No.3 sieve and add a small amount of plant ash to make the water content reach about 20%. The feeding soil thickness of 1 ~ 4 instar nymphs is less than 6.7 cm, and the thickness of 10 cm is suitable for nymphs and adults over 5 years old. In winter and summer, the soil thickness is 20 cm.

Third, feeding management.

1, density: the feeding density can be adjusted with the increase of insect age, and the limit can be 9 kg per square meter. Eupolyphaga sinensis has the habit of eating eggs, so the density of species should not be too high. When Eupolyphaga sinensis is raised in groups, the development process will be 1 ~ 4 years old, so it will be graded when the feeding density approaches a certain number. 1 ~ 6 years old nymphs can be kept together. When the density is too high, they will kill each other and eat the egg sheath. The feeding pit should be dark, leaving only the upper left corner and the lower right corner with a width of 3.3 cm as ventilation holes. When the temperature is above 38℃, the pit door should be opened for cooling, and the pit mud should be thickened to reduce the density.

2. Feed: The best concentrate of Eupolyphaga Seu Steleophaga is bran and rice bran, followed by corn flour and rapeseed cake powder; The leaves of Ailanthus altissima and Elm are the best coarse grains. Secondly, such as sunflower, all kinds of grass, melon skin, vegetable leaves, livestock and fish residues. Feeding methods should be mastered flexibly according to different insect ages, seasons and different development stages. 1 ~ 4 instar nymphs can put some dry soil on the surface of feeding soil and sprinkle concentrated solution on it. Nymphs and adults over 5 years old can sprinkle 1 layer of rice husk with a thickness of 3.3 cm on the surface of the feeding soil, and then sprinkle fine green material. In the low temperature month, you can feed/kloc-0 every other day, and feed every day from June to September, preferably in the morning. During molting, larvae of all ages should be fed with little or no concentrated feed, and then fed normally after molting is basically over.

3. Artificial incubation of egg sheaths: Artificial incubation began in mid-February, and there were 1 aluminum pot and 1 pottery pots in the pots, which were slightly smaller than the pots. Fill the bowl with hatching mud and mix well with the egg sheath. The pot is full of water, the height of which is the same as the soil in the bowl. The bottom of the pot is heated by kerosene lamp, the distance from the bottom of the pot is 1.7 cm, and the water temperature is kept at 32 ~ 35℃. Stir the mud eggs 1 time every few days. All weather, all hatch after 40 ~ 60 days.

4. Keep warm in winter: Eupolyphaga has hibernation habit. When the temperature drops below 8℃, it will dive into the soil, and it will be unearthed again when the temperature rises to 10℃ in April of the following year. Artificial heating can be used in winter and spring in low temperature season, and commercial insects can be produced twice a year in/kloc-0, and fresh insects can be produced 20 ~ 25 kg per square meter. It can be kept in greenhouses in winter, with different styles and sizes, and it can keep warm. For example, the east-west greenhouse is 6 ~ 12 meters long, 3 meters wide and 2.5 meters high. Brick-level double-layer hollow wall. The roof is high in the north and low in the south, with a slope height of 1: 25. The roof is covered with glass. Heating with sunlight, when the temperature is too low, or artificial heating. Put two coal cake stoves in the greenhouse. The furnace is equipped with a heat transfer iron pipe to discharge the gas to the outside. Put the 1 kettle on the stove and adjust the indoor temperature and humidity to keep the temperature at 27 ~ 32℃.

Fourth, pest control.

1, Penicillium: It mainly occurs in the rainy season. The abdomen of Eupolyphaga sinensis (Eupolyphaga sinensis) is dark green with spots, its body is soft, its appetite is poor, and it quickly crawls out of the mud and dies. Once the disease is found, isolate the breeding pests and diseases, replace the dry pit mud and reduce the density. At the same time, spraying worms with 0.5% formalin solution; Or 0.25g of erythromycin is mixed into 0.25kg of wheat bran and continuously fed for 2-3 times until it is cured.

2. Ooaspergillosis: Due to the high temperature and humidity in the tank (bowl), aspergillosis proliferates in large numbers, resulting in the death of eggs and nymphs. The prevention and control methods are as follows: keep the pit soil dry, the humidity does not exceed 20%, harvest the egg pieces 1 time every 1 day, mix 3% bleaching powder and 9 parts lime powder with1part, and sprinkle them on the egg pieces for disinfection. After releasing the worms, the larvae are screened out every three days and fed in the larva pool. Do not feed during the incubation period.

3. acaroid mites: mites are the most dangerous parasites in the production of Eupolyphaga sinensis. When the temperature is above 25℃, the pit mud is wet, which is easy to happen when the material is too much. Juvenile mites parasitize on the membranes of the chest, abdomen and leg base of Eupolyphaga sinensis, which can kill Eupolyphaga sinensis larvae. Control method: scrape the remaining feed on the pit surface together with pit mud to 65,438+0.65 ~ 3.3 cm, and dry it in the sun, or screen out all the Eupolyphaga sinensis and replace it with new pit mud. When changing pit mud, mix 30% dicofol or 20% mite egg fat pesticide with 1: 400 times solution to dry pit mud. 0.037m3 pit mud, 4g medicine,1.6kg water. Rats, ants, frogs and chickens are also natural enemies of Eupolyphaga, so we should take careful precautions.

Verb (abbreviation of verb) harvesting and processing In order to give full play to the feeding function of Eupolyphaga, male nymphs should bask in the sun like female adults. The average adult male nymph is about 6000 per kilogram of dry worms; Full-term female adults, about 1200 dry worms per kilogram. Except for the seeds, the males have to soak in the sun. Screening out 7-8 instar nymphs 1 sieve, picking out males and leaving females to bask in the sun. The female nymph has the highest body weight at 9 ~ 1 1 year, and the drying rate can reach 38 ~ 4 1%. The dry breaking rate of 8-year-old male nymphs is 30 ~ 33%. At this time, harvesting can achieve better economic results. The specific time is from late August to before wintering. Fresh worms are washed and dried, soaked and dried. If the weather is bad, dry it slowly with firepower of about 50℃.
