Background technology
" engineering fly " refers to employing engineering, utilize manufactured feed, housefly through raising, domestication, directive breeding, screening for many years, and in feeding process, " ovum, maggot, pupa, adult " four vegetative stages have been carried out to relatively strict aseptic process, finally formed and can be suitable for the mass-produced housefly experimental population of batch production, nontoxic to human body and environment.
Engineering fly is utilized oneself as a kind of nutrient protein of high-quality long history.In bright, clear epoch and the existing record that eats fly maggot in modern age of China, < < A Dream of Red Mansions > > is referred to as " meat bamboo shoot " using fly maggot and enters to fete as delicacies.China In Nanjing still has the custom of edible fly maggot so far, and in the formula of traditional famous and precious cake " children's's eight-treasure cake ", fly maggot is one of eight delicacies.According to the analysis to fly maggot nutrient component both at home and abroad, fly maggot (butt) contains crude protein 59% ~ 65%, fat 10% ~ 14%, and chitin 8% ~ 10% and vitamin, trace element etc., nutrient component is comprehensive.
Engineering fly is not only a kind of up-and-coming cheapness, high-quality animal protein source, and its deep processing also has larger development potentiality, can be developed into medicine, health products, biochemical preparation, chemical products and feed product.Fly maggot body contains the chitosan up to 20%, in food industry, as flocculant, is able to extensive use.Chitosan can stop absorption of human body as food supplement and help the materials such as excretion triglyceride, cholesterol, and chitosan can be used as thickener, fruit juice or the vegetable juice deacidification agent of food, the carrier of immobilized enzyme and prevent that vinegar from producing the antisettling agent of precipitation simultaneously.
Fly maggot is rich in protein not only, essential amino acid A wide selection of colours and designs, also contain agglutinin, lysozyme, antibacterial peptide, antibacterial protein and chitin isoreactivity material, it is a kind of good feed of new protein sources, not only enjoy the good reputation of " Animal nutrition treasure-house ", and the compositions such as antibacterial peptide wherein can also efficiently be killed multiple pathogens, also be a kind of new type natural antibiotic simultaneously, can strengthen immunity of organisms, in addition to have reproduction speed fast for fly maggot, the advantages such as the low and nontoxic pollution-free of production cost, promote the use of fly maggot activated feed and traditional conventional feed and coordinate the poultry of throwing something and feeding, the biologies such as aquatic products have feed and run off few, fast growth, survival rate is high, cost is low, social economy and the advantage such as profitable on ecology, become the focus of current research.
But the technology content of engineering fly cultivation is at present lower, be mainly extensive cultivation, this cultivation advantage is easy grasp, input cost is low, workable, is the mode that current most engineering fly culturist adopts.In practice, fly maggot breeding, mostly as the supplementing of the aquacultures of certain livestock and poultry, by utilizing feces of livestock and poultry to produce fly maggot, adds in feed and reduces feeding cost, seldom has and only relies on single fly maggot breeding to develop into industry.The research of at present engineering fly cultivation mainly concentrates on fly maggot cultivation aspect, and emphasis is the research to fly maggot culture and condition of culture, about the research of fly pupa formation aspect, have not been reported.
Summary of the invention
The object of the present invention is to provide a kind of quick formation method of fly pupa, adopt the method not only nymphosis fast, simple, easy operating, and the activity of fly pupa keeps, pupa incubation rate is high.
To achieve these goals, the technical solution adopted in the present invention is:
A quick formation method for fly pupa, comprises the steps:
(1) design of nymphosis basin: the plastic basin of the specification of selection 80cm*60*cm*15cm is as nymphosis basin;
(2) urge the design of pupa material: pupa material is urged in preparation, and its formula is: rice bran 60-75%, wheat bran 5-10%, starch 20-30% prepare rice bran, wheat bran and starch in proportion, stir, and makes and urges pupa material;
(3) dehydration: fly maggot and urge pupa material to put into nymphosis basin, stir gently, allow fly maggot Quick uniform dehydration under best material environment, both reached the object of quick nymphosis, keep again the biologically active of pupa;
(4) nymphosis: the condition of controling environment is carried out nymphosis, and stir gently fly maggot once in every 6 hours, stirs in process, become auburn translate into as far as possible above, require in 48 ~ 60 hours all nymphosis;
(5) separation: all become maggot to become after dark brown in nymphosis basin, sieve urging pupa material and pupa to carry out sieving separating by 30 objects immediately;
(6) preserve: the pupa of separator well is proceeded in pupa conservator, preserve.
The described nymphosis basin color of step (1) is white, and because pupa is sepia, maggot is white, is convenient to observe pupation progress.
Step (2) is described urge pupa material good by formulation ratio after, be crushed to 60 ~ 80 orders.
Step (3) is described urges pupa material and fly maggot to add in nymphosis basin by weight the ratio of 1:2, after putting well, stirs gently, reserves the height of 6 ~ 7cm in basin simultaneously, prevents into maggot and climbs out of.
The described condition of controling environment of step (4) refers to controls 33-38 ° of C of temperature, has enough oxygen supplies simultaneously.
The invention has the beneficial effects as follows:
(1) this scheme nymphosis is quick, whole nymphosis and simple to operate in 48 ~ 60 hours, and input cost is low.
(2) adopt the method, by the special pupa material of urging, by fly maggot Quick uniform dehydration under best material environment, the activity of the fly pupa obtaining is kept, and pupa incubation rate is high.
