A: the fly cage that utilizes nylon gauze to process is set in constant temperature, constant humidity, sterile workshop; To plant fly is placed in the fly cage and utilizes the milk powder feeding; And the basin that water is equipped with in placement in the fly cage is to adopt ovum; Every batch of kind fly is raised and eliminated at once in 15～20 days, utilizes hot water or steam will plant fly and kills, and the oven dry abrasive dust is made animal and fowl fodder;

B: after treating that fly blow is hatched into larva, larva is put into the plastic processing frame or the pallet in constant temperature, constant humidity, aseptic workshop and raise, the feed of larval stage is: wheat bran, rice bran, milk powder, brown sugar, dusty yeast;

C: take out the utilization to be further processed of part larva, and let remaining larva pupate naturally, water washes out the fly pupa; Perhaps when remaining larva is supported flavescence in about 5～6 days, its taking-up is put in the dry powder, impels and pupate;

D: after treating that nymphosis is adult, adult is placed in the fly cage raises again, the feed in adult stage is: wheat bran, rice bran, milk powder, brown sugar, dusty yeast, bean dregs, vinasse develop into maturation kind fly until adult;

E: the kind fly that carries out the A step is again raised, breeding work.

The fly maggot that utilizes said method to culture does not carry disease germs, and is nontoxic, can deep processing be the organic feed additive behind the taking-up adult, can be further extracted into organic food and albumen powder raw material through biochemical technology.

The temperature of said constant temperature, constant humidity, sterile workshop is 25～30 ℃, and relative moisture is 60%～70%.According to experiment confirm, fly maggot is grown the fastest under room temperature 25-30 ℃, the condition of relative moisture 60%-70%, and the pupa that becomes is also bigger.

Long 100 centimetres of described fly cage, high 80 centimetres, place kind of fly 1.1～1.3 ten thousand in every cage, every cage powder 20 grams of breast-feeding every day.The excessive area deficiency of ingesting that causes easily of cultivation density, output is not high, and cultivation density is too small to cause the wasting of resources easily.

In said A and the D step, feed is placed in the feed basin of pad of cotion face, and feed and water change secondary every day.Feed is placed in the feed basin of pad of cotion face, can let into fly and stand on the gauze and suck.

In the said A step, be used to adopt in the basin of ovum and also be placed with gauze and wheat bran, be easy to the ovum work of adopting in later stage.

Aseptic nontoxic fly maggot breeding method of the present invention is according to the life habit and the characteristics of fly maggot; Built special breed workshop; Be equipped with sterilization, refrigeration, system heating equipment, guarantee safety and sanitation, bring up the fly maggot that comes out and contain the protein content height; Taking out adult can deep processing be the organic feed additive, can be developed further into organic food and albumen powder raw material through biochemical technology; Through being set, the fly cage guarantees that fly maggot do not flee; The main offcuts that adopt agricultural byproducts are as feed, and aquaculture cost is low, and improve fly maggot output through strictness qualification temp. and humidity.
