Description

Breeding method of larva of Protaetia brevitarsis}

The present invention relates to a method of breeding white-spotted radish larva, and more particularly, to a method of breeding white-spotted radish larva using a fermented sawdust medium.

The white-spotted flower is a herbivorous insect with a body length of 17 to 22 mm and a width of 12 to 15 mm, and its body is dark copper-colored, glossy, and scattered yellow-white patterns. It lives in Korea, China, Japan, and eastern Siberia, and is known to occur once every 1-2 years from April to October. The larvae of the white-spotted flower radish are classified into 1-3 instars according to their size, and the average head width of the 3rd instar larvae is around 43~45㎜ and the body length is 25~37㎜. The body of the larva of this period is milky white, and there are densely yellow short hairs on the whole. Compared to the size of the body, the head is small and the legs are not developed, so when moving, it is moved using a light. Protaetia spp other than white-spotted flowers include fine flowers, true flowers, black flowers, white flowers, grass-colored flowers, broad-brimmed flowers, pan-flowered flowers, true broad-colored flowers, spotted flowers, and first green flowers. There are ignorance, Manchurian spotted flower ignorance, and large purple tiger flower ignorance.

The white-spotted flower radish winters in the state of 3 instar mature larvae, and adults are active during the day and feed on mature fruits such as peaches and pears, or juice from corn and oak trees, and are always clustered. In addition, their larvae live in corrosive soils rich in organic matter such as compost and haystacks.

The white-spotted flower is one of the insects that are completely transformed into adult insects after the adult insects lay eggs and hatch, pass through the 1st to 3rd instars, and then become the pupae after the pupae. The growth period from 1 to 3 years of age takes about 4 to 5 months. The most important influence on the growth rate of young larvae is the breeding environment, which includes factors such as temperature, food, and humidity. The first instar grows until about 10 days elapsed and molts to become a second instar larva. The body becomes enlarged and enlarged, and after about 20 days, it becomes a 3rd instar larva after another molting. The 3rd instar larvae eat and grow hard for about 3-4 months and prepare to become a pupa as they begin to become a species. The species can be classified by the color of the larvae of the 3rd instar, and the one that has changed to golden color is the Jongryeong.

Recently, as attention has been focused on the medicinal properties of white-spotted flowers, many people try to collect large amounts of white-spotted flowers, but there are many difficulties in collecting wild flowers. As a prior art for feed for breeding white spotted radish, sulfur fermented sawdust for slug culture including oyster mushroom mycelium extract produced from cottonseed, rice bran, beet pulp and sulfur-containing oak sawdust medium, and a method for producing the sulfur sawdust (Public Patent No. 2018-0117837) is disclosed, and as a prior art for a method of artificial breeding of white spotted radish, a method using fermented rice straw, etc. (Korea Patent Registration No. 10-0228541), using oak sawdust.

1 is a flow chart for a method of breeding white spotted flower radish larva according to the present invention.

Referring to Figure 1, the method of breeding white-spotted flower radish larvae according to a preferred embodiment of the present invention comprises the steps of forming a mushroom fruiting body (S10); Harvesting the mushroom mycelium powder containing sawdust (S20); Manufacturing a fermented product (S30); Germinating barley from the fermented product to grow sprout barley (S40); And it may include the step (S50) of rearing the larvae of white spotted flowers.

The step of forming the mushroom fruiting bodies according to step S10 is to inoculate the mushroom mycelium in a sawdust medium to cultivate the mycelium to form a mushroom fruiting body.

The mushroom may be any one of oyster mushroom, reishi mushroom and cordyceps mushroom, preferably oyster mushroom, but is not limited thereto.

Oyster mushroom is a mushroom belonging to the pine mushroom family, and in Chinese characters it is called Cheonhwasim·man. In autumn, it grows in large numbers of dry trunks of broad-leaved trees such as oak, alder, cottonwood, willow, etc., fallen tree trunks, and cut stumps, and is distributed not only in Korea, but also in China, Japan, Europe, North America, and Siberia. . Fruiting bodies occur in October-December and March-April, and the caps are grayish white or light grayish brown, forming a semicircle or fan shape. Artificial cultivation is done by cultivation of logs or bottle cultivation of sawdust. When seeding is inoculated in spring on logs, fruiting bodies are formed in autumn.

To inoculate the oyster mushroom mycelium, first prepare the oyster mushroom spawn. To this end, oyster mushroom progenitors were transplanted into PDA, MEA medium, etc. in a sterile phase, and then hyphae cultured for 10 to 15 days in an incubator at a temperature of 25 to 28°C, and preserved at -20°C and used.

The sawdust medium is prepared by mixing 65% by weight of silver sawdust, 23% by weight of dermis, and 12% by weight of rice bran, which are the main materials, followed by mixing and kneading water.

Here, the tree used as the main material of the medium is aspen (scientific name: Populus tomentiglandulosa), and the silver aspen is a natural hybrid formed between aspen (P. davidiana) and Eunbaekyang (P. alba). As a biological classification, plant family (Plantae), pizza plant (Angiospermae) dicotyledonae (Dicotyledoneae) willow tree (Salicales) willow tree family (Salicaceae). It is beautiful and can be used as a tree planting, guidance planting, and buffer planting. In the present invention, silver ash is used as sawdust. Logs are harvested from around November when the sap stops moving to February of the following year, and is naturally dried in the shade after logging. When the moisture content is 35 to 45%, the solid wood is cut to about 12 to 15 cm in diameter and 20 cm in length, and is prepared by pulverizing it into a 40 mesh particle size with a sawdust maker.

The dermis (Citrus Unshiu Peel) refers to the dried peel of the mature fruit of Citrus unshiu Markovich. As a scented tendon placebo, it is used for gastritis and indigestion, and as an antitussive, antitussive, and expectorant. In the present invention, the dermis may be purchased commercially, or may be harvested or cultivated in nature.

Rice bran is called rice bran when it is milled from brown rice to white rice. Brown rice is the rice hull that is peeled off the outer husk of rice by threshing the rice, and white rice (white rice) is the rice hull and the inner husk (rice bran) after grinding the brown rice.

The substance called "GABA", which lowers high blood pressure in the rice snow, has the function of preventing adult diseases by reducing triglycerides in the blood and enhancing liver function. Rice bran improves blood circulation and activates the natural healing power of humans. It boosts immunity and turns a weak acidic constitution into a healthy constitution. Rice bran is rich in vitamins such as hemicellulose, dietary fiber, inositol, choline, niacin (B3), tocopherol (E), thiamine (B1), and pantothenic acid (B5).

After adjusting the moisture content of the medium to 65% to 70%, put about 1 kg each in a heat-resistant polypropylene bag and close the cap to perform 7 hours at normal pressure sterilization (100°C) and 90 minutes for high pressure sterilization (121°C). . Cool the autoclaved medium to about 15℃ before seed inoculation.

Oyster mushroom spawns cultured in a sterile room or sterile bed are inoculated into the sterilized and cooled sawdust medium in an inoculation room maintained at 15°C. Inoculation method is to add about 100g of seed per 2kg of sawdust medium. At this time, the work of opening and closing the heat-resistant plastic bag should be performed as soon as possible with the shortest exposure time to prevent contamination by various germs. The sawdust medium after inoculation is cultured for 25 to 30 days in a culture chamber maintained at a temperature of 20 to 25°C. At the beginning of cultivation, the temperature is maintained at about 20 to 22°C for 7 days, and then culture is performed at about 25°C after the oyster mushroom spawns are settled on the sawdust medium.

The cultivation of fruiting bodies in the sawdust medium in which the cultivated oyster mushroom spawns are established is to form fruiting bodies by moving the bottle medium in which the mycelium cultured at 25°C for 30 days is cultured to a cultivation room at 18°C and 95% relative humidity for 10-15 days do.

In the step of harvesting the mushroom mycelium powder containing sawdust according to step S20, the fruiting bodies of the mushroom mycelium are cultivated in a bottle medium and then pulverized using a crusher to harvest the mushroom mycelium powder containing sawdust.

The fruiting bodies of oyster mushroom mycelium are cultured at 25℃ for 30 days in a solid bottle medium, dried to a moisture content of 4-5% at 60℃, and then pulverized to a particle size of 100 mesh using a crusher. Finally, a medium containing sawdust. To obtain a mycelium powder containing oyster mushroom.

The step of preparing the fermented product according to step S30 is to ferment the sawdust medium in a fermenter to prepare a fermented product.

As in the case of step S10, the sawdust medium is prepared by mixing 65% by weight of oak sawdust, 23% by weight of dermis, and 12% by weight of rice bran, as in the case of step S10, followed by mixing and kneading water. At this time, preferably, when the fermented product of the present invention is manufactured using the waste sawdust medium discarded after cultivation of oyster mushrooms, there is an advantage of reducing production cost.

A fermented product can be prepared by fermenting a mixture of Streptococcus thermophilus, Bifidobacterium longum, and Lactobacillus reuteri in the sawdust medium.

Here, the Streptococcus thermophilus, Bifidobacterium longum, and Lactobacillus reuteri are mixed at a weight ratio of 1:1:1.

The fermentation microorganism may be introduced in the form of an EM (Effective Microorganisms) stock solution. EM (Effective Microorganism) is an abbreviation of a useful microbial group. It is a complex microbial preparation in which 80 groups of 10 kinds of microorganisms that are beneficial to humans are combined and cultured among many microorganisms existing in nature. Protobacteria constituting EM bacteria are generally yeast, lactic acid bacteria, yeast, photosynthetic bacteria, Actinomyces, and mold fungi, which have been used by humans for a long time in food fermentation, etc. It is a group of microorganisms that lead in the direction of revitalizing nature by microbial coexistence, producing antioxidant or antioxidant substances, and suppressing spoilage.

The EM (Effective-Microorgarnisms) fermentation broth used in the present invention can be either an EM stock solution or an EM active solution distributed on the market. The EM active solution is mixed with 0.1 to 2 parts by weight of saccharides (at least one selected from fructose, sugar, honey, and oligosaccharides) to 100 parts by weight of water, and 5 to 20 parts by weight of the EM stock solution in water in which the saccharides are mixed After mixing, it can be made by incubating in an anaerobic state for 1 to 5 days at a temperature of 29 to 35°C. More preferably, 100 parts by weight of water, 1 part by weight of sugar, and 20 parts by weight of EM stock solution are mixed at a temperature of 32°C. It can be prepared by incubating for 3 days.

More preferably, the EM (Effective-Microorgarnisms) fermentation broth used in the present invention is Streptococcus thermophilus, Bifidobacterium longum, and Lactobacillus reuteri in the EM stock solution. By mixing, each strain may be included in an amount of ^{3.0x10 6 cfu/g or more.} In this case, the nutrient content, fermentation properties, and microbial phase of the mushroom waste medium are further improved, and the effect of preventing the occurrence of mold in the feed composition for white spotted radish larvae can be further improved by further improving the harmful bacteria inhibiting effect. .

The step of growing sprout barley by germinating barley from the fermentation according to step S40 is to grow sprout barley by adding the fermented product to a breeding box and then germinating barley from the fermented product.

The step of rearing the white-spotted radish larvae according to step S50 is to breed the white-spotted radish larva after putting the mushroom mycelium powder containing the sawdust into the breeding box. The white-spotted radish larvae are bred while ingesting the mushroom mycelium powder containing the sawdust and sprout barley grown from the fermented product.
