(1) Corn flour: the corn flour is rich in saccharide, glutamic acid and lysine, also contains a large amount of vitamin A, E, B2, and is rich in cellulose and linoleic acid, so that the corn flour is sufficient in nutrient components and easy to digest and absorb, and the corn flour is one of the main components of the feed in most formulas containing wheat germ or soybean flour; one of hosts of spodoptera frugiperda larvae is corn, so that a small amount of corn flour is mixed, and the spodoptera frugiperda larvae has a good promoting effect on the growth and development of spodoptera frugiperda;
(2) soybean meal: the bean substance is one of the main ingredients commonly used in the artificial feed for lepidoptera insect larvae, particularly soybeans are rich in soybean protein and stigmasterol, also contain rich unsaturated fatty acid, soybean phospholipid, vitamin B1, vitamin B2 and other nutritional ingredients, and the soybean meal is rich in saponin, protease inhibitor, isoflavone, molybdenum, selenium and other ingredients and is also an indispensable substance of the artificial feed for insects;
(3) yeast powder: the feed-grade yeast powder specified in the industrial standard of Ministry of light industry of the people's republic of China is a product prepared by taking carbohydrates such as starch, molasses, high-concentration organic waste liquid such as monosodium glutamate and alcohol as main raw materials, culturing saccharomycetes through liquid ventilation, separating yeast thalli from fermentation of the saccharomycetes and drying the saccharomycetes, and belongs to one of single-cell protein feeds; the yeast powder is used as a feed additive protein source, so that the protein content of female pupae can be greatly increased within a certain range, and the fertility of adults is improved.
(4) Agar: agar is widely applied to artificial insect feed, has good forming and moisturizing effects on the feed, and is beneficial to feeding larvae; the edible agar strips are low in price, non-toxic and harmless, particularly have remarkable stability, hysteresis and hysteresis, are easy to absorb water, and have a special stabilizing effect;
(5) ascorbic acid: ascorbic acid, also known as vitamin C, is a water-soluble vitamin. The feed-grade ascorbic acid is used in animal husbandry and aquaculture, can promote the growth of young animals, prevent skin lesions, depilation, skin thickening, scurvy and the like of the animals, and is beneficial to improving the production performance of the animals such as the milk yield of cows, the growth speed of broilers, the egg yield of laying hens and the like;
(6) vitamin B complex: the vitamin B complex is a compound preparation and contains vitamin B1, vitamin B2, vitamin B6, nicotinamide and calcium pantothenate; the vitamin B complex participates in the metabolism process of organisms, and provides coenzyme necessary for various metabolic links in vivo and important coenzyme raw materials for tissue respiration. Nicotinamide is a component of coenzyme I and II, participates in biological oxidation, and plays a role in hydrogen transfer; vitamin B6 produces a physiologically active substance together with ATP in vivo, is a prosthetic group of various enzymes, and participates in the metabolism of amino acids and fats. Calcium pantothenate is coenzyme A precursor, participates in sugar, fat and protein metabolism, and plays a role in transferring acyl in metabolism;
(7) roxithromycin: the roxithromycin is a new generation macrolide antibiotic, and mainly acts on gram-positive bacteria, anaerobic bacteria, chlamydia, mycoplasma and the like; the in vitro antibacterial effect is similar to that of erythromycin, and the in vivo antibacterial effect is 1-4 times stronger than that of erythromycin;
(8) sorbic acid, propionic acid: the good artificial feed for spodoptera frugiperda larvae can not leave the preservative. Sorbic acid is a commonly used preservative, and has particularly obvious effect in summer with high temperature and high humidity; meanwhile, propionic acid is added into the Spodoptera frugiperda larva artificial feed and is mainly used as a preservative and a mildew preventive;
(9) citric acid: citric acid has mild and refreshing sour taste, and is widely used for preparing various beverages, soda water, wine, candy, snack, biscuit, canned fruit juice, dairy products and other foods; meanwhile, the product improves the sensory properties of food, enhances appetite and promotes the digestion and absorption of calcium and phosphorus substances in vivo, and is an acidulant and a preservative for beverage and food industries.
