螳螂Manual rearing and utilization of new technologies

Aphid, which is the collective name for insects of the order Mothidae, is a relatively large species of insect, commonly known as the knives and crickets. It has more than 1,550 known species, and the common species in the north are large swords, small swords, and thin bills. Morphological characteristics The large iliac crest has irregular transverse veins on the hind wings, with large black markings at the base and slightly longer ends than the forewings. There are many small particles on both sides of the middle longitudinal groove in the first half of the Chinese burrow, and the lateral edge teeth are obvious. The particles on both sides of the middle ridge of the second half are not obvious, and the dentition on the side edge is not obvious; the hind wings are dark brown with transparent markings. Thin-winged dorsal hind wings exceed the fore wings. Occurrence of the regular egg period in mid-July each year, most species that gradually enter the adult period. In late August, males and females mated. The females chose to lay eggs on branches or walls, fences, stones, and stone seams. Females generally produce 1-4 oocytes. At the time of spawning, first secrete a layer of adhesive and then produce a layer of eggs. The first-produced egg sheath is white or milky white and is soft. After 5-10 hours, it becomes yellowish-brown or yellow-brown. In early June of the following year, the wintering eggs began to hatch until the beginning of July. The nymph stage egg is developed into a nymph by an embryo in the sheath, and then it is released from the egg membrane, and the egg shell and the body of the insect are adhered by means of the secreted colloidal filament on the tenth web, sometimes it can be drawn into more than 10 Long strings. Soon, the individuals who hatched early, that is, swaying through the breeze, used their feet to seize the surrounding objects to go their separate ways. The habit of self-inflicted larvae of 1-2 instar nymphs is strong, usually 10%-30% in natural environment, and up to 70%-90% under artificial breeding conditions. Adult stage 7-10 months each year is the adult stage. Adult emergence time is generally in the morning and morning. After emergence into adults, mating can be carried out for 10-15 days, and mating can be repeated several times during the life of the mandarin, and the mating time is 2-4 hours. Mating often occurs when females attack the male and bite on the male's head, but this does not affect mating. People call it the phenomenon of "partners and husbands." The common species of life habits are one generation per year in North China and East China, and they use eggs as an ovum for wintering. Usually eggs hatch in May and June. Incubation period: The female nymph is generally 7-8 years old, and the male nymph is 6-7 years old. Adults begin to emerge in mid-August, and mating begins 10 days after emergence of the adult. The average duration of mating to the first spawning period was 23 days for Chinese swordshoe crabs and 18 days for broad-leaved ducks. Outdoors, adults usually lay eggs in the middle of September and begin to die in late September. Individual adults can live until the end of October to the beginning of November. There are more than 30 kinds of mature artificial breeding technology for artificial and efficient scale breeding technology. Collection of provenances A variety of earthworms spend winter on egg branches, tree trunks, grass stems, walls, or stones. Oviposition can generally be started from September to February. When picking eggs, choose large egg masses, thicker surface protective layer, strong brilliance, high-quality, robust eggs with no breaks, abrasions, or wormholes by parasites, together with a section of sticking twigs of egg masses, insert and put a little Water cans in a bottle. Before hatching eggs begin to hatch (before the temperature rises to 20°C), preparations before feeding should be done. Feeding insects are predatory insects that like to capture live insects, especially on sport insects. Young nymphs before the third instar are difficult to feed if they have no live insects. Therefore, live worm feeds, such as aphids and house flies, should be prepared before hatching of quail eggs. Aphids are highly fertile and easy to raise. The cruciferous plants can be planted in flower pots or small plastic impregnated plants in advance, and after being emerged, they are inoculated and served for propagation. Other feed insects include wax mites, corn borers, cabbage white butterflies, earth elements, and yellow mealworms. After the 3rd instar of artificial ingredients, if the amount of insects is large, it is difficult to meet the needs of the limited live feed. Therefore, artificial feed must be prepared. Here are three successful artificial feed recipes: Formula 1: Pour 250 ml of fresh water into the container, take a small amount of water, mash 5 g of yeast flakes into water, and dissolve 50 g of egg yolk and 20 g of yeast. Honey, 20 grams of sucrose, all poured into, after mixing well, into the pot and boil, cool and reserve. Formula 2: 100 grams of fresh pork liver (other animal liver can also be), washed and chopped mash into a paste, add 50 grams of sucrose, mix well and spare. Formula 3: 100 ml of water, 40 g of fresh pork liver, 20 g of aphid powder, 5 g of soy flour, 20 g of sucrose, 20 g of agar, and 1 g of yeast tablets. When using the above three formulas, great attention must be paid to sanitation. After the prepared feed is cooled, it can be stored in the refrigerator for a short time and used as needed. If a large number of feeding, it is best to prepare once a day based on the amount of use. Because of the habit of fratricidal killings, the breeding cages have a certain degree of difficulty. Outdoors are housed in 12-meter-meter-meter-two-meter-wide cages, and cages such as dwarf trees and cotton are planted and transplanted in cages, and habitats are provided for them to reduce contact and avoid mutual killings. At the same time, feed artificial paste. The insect research institute of Shandong Agricultural University uses feed insect Tenebrio larvae and flies to feed quail, which can complete the growth process and lay eggs. Environmental control Artificial anti-season cultivation, breaking dormancy, simulation of temperature and humidity, artificial creation of natural conditions, 250 watts of infrared light per day, plus additional ultraviolet light. Harvesting and processing are harvested in the fall to the spring of the following year. Post-harvest clean-up of impurities, immersed in boiling water or steaming for 30-40 minutes to kill the eggs in the ovary sheath, steamed dried or dried is a Chinese medicine mulberry, spare or sale. Note that the eggs must be killed. Otherwise, after the larvae hatch, the efficacy decreases and the quality is affected. Concocted: Take the protozoa clean, with 2% -5% saline solution, mix well, moisten, steam for 2 hours to remove, dried or slow fire dry. Economical use of medicinal value Chinese medicinal mulberry is the ovum sheath of the insect family. Mulberry contains 18 kinds of amino acids, 8 of which are essential amino acids and 7 types of phospholipids. Mulberry has anti-frequency and convergence effects. Phospholipids reduce atherosclerosis, and can promote the development of red blood cells and other cell membrane synthesis, mulberry sweet, salty, warm, non-toxic, into the liver and kidney. There is a kidney yang, solid fine urine function. Indications of enuresis, nocturnal emission, frequency, kidney back pain, neurasthenia, also applies to women with menstruation, blood dystonia embolism. The market price of mulberry has reached 60-80 yuan/kg. In addition to mulberries, wolfberry can also be used as a medicine, which is to dry the adult worms into medicine. There are nourishing and strengthening the body, strengthening the kidneys and benefiting the essence, and stopping phlegm. Indications physical weakness, impotence, nocturnal emission, child convulsions, enuresis, acne and neurasthenia. The main clinical application is compatibility with other drugs for the treatment of rheumatoid arthritis and rheumatoid arthritis. The biological defense value can be used to prey on more than 40 kinds of pests, such as flies, mosquitoes, cockroaches, mires, bitter moths, moths, eggs, larvae, exposed cockroaches, small insects such as adults, cockroaches, planthoppers and other large insects. Food value is a highly nutritious, high-protein food insect. Ornamental value is cultivated by artificial anti-seasonalism, which can make people appreciate the embarrassment of the anniversary. It is also a good material for building a small zoo and a wild insect garden.
