Description

Artificial synthetic diet of a kind of 2 committee noctuids and preparation method thereof
Technical field
The present invention relates to a kind of artificial synthetic diet and preparation method thereof, be specifically related to a kind of synthetic diet on probation during for 2 of artificial propagations committee noctuid and preparation method thereof.
Background technology
2 committee noctuids (Proxenus lepigone Moschler) belong to Lepidoptera Lepidoptera Noctuidae Noctuidae, committee's Noctua.2 committee noctuids are as research and controlling object on corn, especially carry out the research work such as biology, chemical prevention, steriliation by irradiation, study its artificial synthetic diet and mass rearing reproduction technique, solve examination worm supply problem, to Maize Production, be very important, because 2 committee noctuids are new hair style insect, its captive breeding technology feed is also immature, available technology adopting maize leaves is as natural feed, but maize leaves is subject to the impact in season and remains agricultural chemicals, research and the preventing and controlling of 2 committee noctuids have so just been hindered.
Two select committee noctuid, and in field, mainly to take Wheat Straw, corn root be food, to cellulosic, be in great demand, in the disclosed technical scheme of Chinese patent publication No. CN102835596A and CN102919563A, all ignored 2 committee noctuids to cellulosic wilderness demand, the cellulose components adding in feed is less; Chinese patent publication No. CN102578432A discloses a kind of man-made feeds of 2 committee's exigua larvaes, in this feed using Amaranthus retroflexus leaf powder for 2 committee's exigua larvae feeds as primary raw material, and Amaranthus retroflexus is weeds in field, only be distributed in China small part area, and be subject to seasonal restriction, in most areas or the time be difficult to obtain, cause difficulty to 2 committee's exigua larvaes of raising, be not easy to implement, and the normal enrichment nitrate of this plant, larva is excessive may cause after edible poisoning.Chinese patent publication No. CN102630829A discloses a kind of 2 committee's exigua larvae feeds and preparation method thereof, in this feed, containing casein is a kind of albumen condensate, add to and in feed, feed 2 committee's exigua larvaes, be difficult for being digested and assimilated by 2 committee's exigua larvaes, affect the immunity of its larva; And adopt the mode of boiling when prepared by this feed, its weak point is that one time to produce is more, and unnecessary feed re-uses after refrigerator storage, be heated and easily produce a large amount of globules, cause the death of 2 committee's exigua larvaes very high.
Summary of the invention
For existing 2 deficiencies that committee's noctuid man-made feeds exist, the invention provides artificial synthetic diet of a kind of 2 committee noctuids and preparation method thereof, it is main component that this feed be take wheat bran powder, mushroom powder, with other auxiliary materials such as wholemeal, peptone, form, adopt the feed of certain proportioning to raise 2 committee noctuids, its survival rate, percentage of pupation, eclosion rate, single female egg laying amount all significantly improves; And feed can not be subject to the impact in season, can not contain the residual components such as agricultural chemicals yet; Meanwhile, this feed adopts micro-wave oven to be prepared, and simple to operate, amount of preparation is controlled, is used while allocating, and has improved efficiency of feed utilization, has solved the more problem that is stored in refrigerator of feed one time to produce.
Concrete technical scheme of the present invention is:
The artificial synthetic diet of a kind of 2 committee noctuids, its proportioning is counted by weight: wheat bran powder 25-35 part, wholemeal 8-14 part, mushroom powder 4-10 part, peptone 2-6 part, soy meal 4-8 part, corn flour 4-10 part, vitamin C 0.9-1.4 part, dusty yeast 3-9 part, formaldehyde 0.5-1 part, sorbic acid 0.5-1 part, agar powder 6-8 part.
Inventor finds after deliberation, contains multiple nutritional labeling in this feed, can meet the needs of 2 committee's noctuid growths completely.Because wheat bran powder contains abundant dietary fiber and B group vitamin, 2 growing of noctuid of committee are had to important function, reduced the autotomy phenomenon of 2 committee's exigua larvaes, therefore the consumption of wheat bran powder is limited to weight portion 25-35 part.
Described mushroom powder is the fresh mushroom without agricultural chemicals of buying, as mushroom, straw mushroom, flat mushroom and mushroom etc., preferred flat mushroom, its low price, be conveniently easy to get, after rinsing with clear water, control solid carbon dioxide divides, being placed on electric drying oven with forced convection 80 degree dries 24 hours, after oven dry, obtain mushroom dry, adopt again pulverizer by the dry grinds of mushroom, cross 160 mesh sieves, the mushroom powder obtaining is like this fine and smooth, the Impurity removal some can not being ground, make quality of the fodder better, put into drying bottle after finally mushroom powder is cool standby.Raw material of the present invention, except special instruction, is commercially available gained.
Because mushroom nutritional labeling is abundant, it is rich in high protein, low fat, each seed amino acid, mineral matter, the nutritional labeling such as vitamin and polysaccharide, and can promote well the absorption of larva to other food nutritions, therefore the quick healthy growth that is conducive to 2 committee noctuids, during concrete use, can adopt conventional use mushroom, as mushroom, straw mushroom, flat mushroom and mushroom etc., and in use, whole thalline of whole mushroom all can be processed into mushroom powder and use, reduced production cost, in use mushroom to take the weight of its dry weight be use standard, prevent in fresh mushroom moisture more and cause the deficiency of nutriment.If the content of mushroom powder is too low, or cause nutritional labeling not enough, and cause the development time of 2 committee noctuids to extend, lose weight, pupate, eclosion rate reduces; After the same consumption when mushroom is too high, can produce toxicity, thereby cause 2 committee's noctuids food poisonings and death, so the consumption of mushroom powder is 4-10 part.
Described peptone is rich in organonitrogen compound, also contains a large amount of vitamin and carbohydrate.Compare with protein, the molecular weight of described peptone is less, more easily by 2 committee noctuids, is digested and assimilated, and has improved the immunity of organisms of 2 committee noctuids; Described peptone is enough to provide sufficient nutriment for the growth and breeding of 2 committee noctuids, and after adding peptone in described feed and feeding 2 committee noctuids, its larvae pupation rate, eclosion rate all improve.
Described wholemeal is rich in the mineral matters such as protein, carbohydrate, vitamin and calcium, iron, phosphorus, potassium, magnesium; Described soy meal contains rich in protein, unrighted acid, Soluble Fiber and several amino acids; Described corn flour can provide carbohydrate, protein, fat, carrotene, riboflavin and natural complex C, vitamin E; Described vitamin C provides 2 committee's noctuids required vitamins of growing; Described dusty yeast has rich in protein, amino acid, vitamin and trace element, and contain digestive ferment and some unknown growth-stimulating factors, and can promote insect metabolism, be conducive to digest and assimilate, accelerate growing and the performance of production performance of insect, can also improve defending and fighting against diseases ability; Described formaldehyde and sorbic acid are all anticorrisive agents, sorbic acid is the food additives of generally recognized as safe, efficient corrosion resisting, be mainly used in killing fungi, mould, and formaldehyde all has good inhibition to bacterium, fungi, adopt micro-anticorrisive agent to make the freshness during 2 committee noctuids are edible, guarantee growing of 2 committee noctuids; Described agar powder is as stabilizing agent, and its Main Function is that each component in feed formula is frozen into piece, makes feed be easy to use.
Although what each component in feed formula provided is mainly cellulose, protein, amino acid, mineral matter etc., but amount contained in each composition is different again, nutrient balance is the key problem of development man-made feeds, the imbalance of food nourishment composition affects growing of 2 committee's exigua larvaes, because the imbalance of nutritional labeling need to increase metabolism and excretion activity, delay the growth of larva and the conversion efficiency of reduction food, finally have influence on the g and D of larva.For life habit and the feeding habits of 2 committee noctuids, inventor has provided the best proportioning of the artificial synthetic diet of 2 committee noctuids, counts by weight: 30 parts, wheat bran powder, 12 parts of wholemeals, 8 parts of mushroom powders, 4 parts of peptones, 6 parts of soy meals, 8 parts of corn flours, 1.2 parts of vitamin Cs, 6 parts of dusty yeasts, 1 part, formaldehyde, 1 part of sorbic acid, agar powder 6-8 part.
In addition, it is main component that the present invention be take wheat bran powder and mushroom powder by described feed formula, and this is not only because contained nutritional labeling is high in wheat bran powder and mushroom powder, and has well controlled viscosity and the sugariness of feed.If viscosity and sugariness are too large, newly hatched larvae is easily stuck and death.
