Life habits of Eupolyphaga:
Eupolyphaga sinensis is an important medicinal insect, which lives in dark, humid and humus-rich loose soil. It is afraid of the sun, lurks in the daytime and moves at night. The optimum growth temperature is 28 ~ 30℃. If it is lower than 0℃ or higher than 38℃, it will cause a large number of deaths of adults and nymphs. When it drops to 8℃, it will stop moving and enter the dormant period.
Eupolyphaga sinensis needs to go through three stages: egg, nymph and adult. It takes about 8 months for males to grow wings from nymphs, and 9 ~11month for females to mature without wings. The male insect died 5-7 days after mating. Female insects can lay eggs one week after mating, and they can lay eggs once for life.
Source of food varieties of Eupolyphaga Seu Steleophaga:
Eupolyphaga is an omnivorous insect, and its feeding characteristics are that it likes fresh food, especially bran and rice bran, followed by corn flour, broken grains, peanut cake, soybean meal, miscellaneous fish, meat and various coarse materials such as grass leaves, melon and fruit peels, chicken and cow dung. If the growth is slow by feeding grass and other feeds alone, the complete feed can be 72% wheat bran, 20% corn flour, 5% bean cake and 3% animal feed (cooked feed). Boil it with boiling water when feeding, and add 30% ~ 40% vegetables or melons and fruits. Individuals can grow into adults after being fed with complete feed for 5 ~ 6 months.
Soil element shape structure
The adult Eupolyphaga mother is about 3.4 cm long and 2 cm wide. The body is oval, some Eupolyphaga are gray in the back, some Eupolyphaga are white in the back, flat from top to bottom, reddish brown in the chest, with a small head hidden in the chest, a pair of tentacles and a pair of compound eyes. Chewing mouthparts, with transverse joints on his back and tiled arrangement, has 3 pairs of feet and 2 pairs of wings on his chest, which is relatively developed. The front wing is leathery, the rear wing is translucent, folded on the back, and has the ability to fly for a short distance, flying up to 5 ~ 6 meters from top to bottom, with a pair of tails. Eupolyphaga lays eggs after male and female mating, which looks like rice. It is1~1.5 times larger than rice, about one centimeter long and reddish brown in color. There are longitudinal stripes on the surface of the egg mass. There is a larva in each longitudinal stripe, arranged in two rows, and an egg block contains 8 ~16 larvae.
Eupolyphaga culture-how to control temperature and humidity
Adjusting the temperature and humidity can be solved by the following methods: (1) heating: when the required temperature cannot be reached in the feeding environment, the indoor temperature can be increased by using a stove, etc., and the local temperature of the pit and pool can be increased. (2) Cooling: If the temperature in the pit and pond exceeds the suitable temperature of Eupolyphaga Seu Steleophaga in summer, indoor ground sprinkling can be adopted, indoor ventilation and ventilation in the pit and pond can be strengthened, exhaust fans can be installed, or water basins and ice trays can be added in the pit and pond. When the temperature continues to be high, when dead insects are found, they should be screened in time to screen out old nymphs or some adults, and then treated as medicine, so as to reduce the population density in pits and ponds and reduce the food intake. (3) Humidification: When the humidity in the breeding ground or pit or pool is lower than15%, the articles with large evaporation surface after water absorption should be placed by spraying and sprinkling on the ground, such as wiping the absorbent soft foam, cotton fabric, soaked clothes and quilts, etc., to disperse the moisture. (4) Humidity reduction: When the humidity in pits and pools exceeds 30%, timely measures should be taken to reduce humidity, such as opening doors and windows and exhausting fans, and strengthening ventilation. If the outdoor atmospheric humidity is too high to last, calcium chloride wooden boxes and lime boxes should be placed in the corners of pits and pools to achieve the purpose of local humidity reduction.
Medicinal value
Eupolyphaga is distributed in the vast areas of north and south China. Eupolyphaga, the medicinal name of Eupolyphaga japonica, is distributed in North China, Northeast China and Northwest China. Eupolyphaga Phnom Penh, the medicinal name of Eupolyphaga Phnom Penh, is distributed in the south of the Yellow River in China, especially in the southeast coastal provinces and cities.
According to Compendium of Materia Medica, Eupolyphaga Seu Steleophaga is a traditional Chinese medicine, and it is a kind of precious cool Chinese medicine. It tastes salty, cold and toxic, and can dispel blood stasis, break accumulation, dredge collaterals and heal injuries. It is effective in treating amenorrhea, postpartum abdominal pain and traumatic injury. In addition, the anticoagulant and anti-hypoxia effects of Eupolyphaga Seu Steleophaga are used in modern clinical medicine to treat coronary heart disease, hypertension, rheumatism and bone pain, and also have high therapeutic effects on leukemia, acute hepatitis B, cerebral infarction and malignant tumors. There are more than 200 kinds of Chinese patent medicines compatible with Eupolyphaga Seu Steleophaga, such as Dieda Pill, Zhishang Powder, Qilisan, Xiaozhong Ointment, Baiyao, Ginseng-turtle Beetle, Zhuifeng Pill, Chushangxiao, Chinese Eupolyphaga Seu Steleophaga Capsule, Chinese Eupolyphaga Seu Steleophaga Wine, Tongxinluo Capsule, Naosetong, Yaotongpian, Yaotongning and Dieda Zhentong Ointment. At the same time, with the development of the times, insect food is becoming more and more popular. Eupolyphaga Seu Steleophaga contains high protein and low fat, which can prevent many diseases and has good edible value. Eupolyphaga Seu Steleophaga tonic wine and other products are also made.
Driven by the breakthrough of consumer market and varieties, the current market price of cultivated Eupolyphaga is stable at 23 ~ 26 yuan per kilogram, and the price of edible insects (frozen) is at10 ~15 yuan per kilogram. The following four points are put forward to promote and improve the economic benefits of Eupolyphaga culture.
(1) Feeding facilities can be built indoors or in greenhouses according to their own conditions. The size of the feeding pool depends on the amount of breeding. The feeding pool is built in a three-dimensional frame with bricks, sealed with 4.5 cm plastic strips around it, and the bottom of the pool is treated with cement to prevent escape. Eupolyphaga can also be raised in plastic boxes or plastic pots. The pots and boxes are set up layer by layer for three-dimensional culture, so as to make full use of indoor space and improve yield.
(2) Habits Eupolyphaga is an omnivorous insect. It likes to live in dark, humid, loose and fertile soil with rich humus, and mostly comes out for activities, foraging and mating at night, fearing direct sunlight.
(3) The temperature requires that the artificially cultivated Eupolyphaga must be cultivated in a constant temperature and three-dimensional manner. The suitable temperature for activities is17 ~ 38℃, and the optimum temperature is between 23 ~ 32℃. At this temperature, Eupolyphaga can grow and lay eggs in four seasons. It takes 7 ~ 8 months to scientifically and reasonably raise Eupolyphaga from larvae to adults, and the shortest time is 6 months. One feeding room can produce two batches of adults every year.
(4) Feeding technology No matter whether the feeding equipment is a pond or a box, loose and fertile feeding land must be laid on the bottom with a thickness of 5 ~15 cm. The thickness of feeding soil depends on the age of the insect, and the smaller the insect age, the thinner the soil layer is. The water content of the feeding soil should be kept at about 20%, and the relative temperature should be kept at about 70%. The feeding time of Eupolyphaga should be chosen in the evening, and it should be fed/kloc-0 times a day. The feeding materials are mainly bran and washed vegetable leaves. Moderately add water, stir evenly and sprinkle on the surface of the feeding soil, so that the fed bran can be eaten completely, and it is better to have more leafy vegetables.
