Description

The production method of aseptic fly and fly maggot

At insect world, the fertility of fly ranks first place, and a pair of fly can breed 2,660 hundred million fly maggots in four months, and weight can reach more than 600 tons.With aseptic fly and aseptic fly-maggot is the feedstuff that animal albumen powder that primary raw material is made is made poultry and livestock, can promote and quicken growth, the growth of poultry and livestock.Contain because of aseptic fly and fly maggot and plant trace element, lower fat surplus 18 seed amino acids and ten of more animal protein and needed by human body, thereby also can develop human good food, health products or medicine.Yet do not see the production technology of announcing aseptic fly and fly maggot so far as yet, influence the development and use of aseptic fly and fly maggot.

The objective of the invention is to invent the production technology of a kind of aseptic fly and aseptic fly-maggot.

Step of the present invention is as follows:

1, select housefly for cultivating the fly kind of culturing: the fly kind that China has found at present has kind more than 1500, population quantity maximum wherein, and fertility is the strongest, and movable season, the longest fly kind was a housefly, and therefore selecting housefly is the fly kind of cultivating and culturing.

2, cultivate no bacterial classification fly from the housefly of occurring in nature.Method is that the egg-incubating box that will be placed with egg-incubating material is placed on the place that the natural world housefly multiplies, after treating that housefly lays eggs, it is 25-38 ℃ that egg-incubating box is placed on temperature, relative moisture is to hatch into larva under the environment of 60-80%, larva is put into thimerosal soak a moment, pull the back out and use normal saline flushing, use distilled water flushing again, pupate then, be placed on the cage back warp again and spend the adult stage and cultivate into second generation housefly.Cultivate third generation housefly with the second generation housefly that cultivates with said method again.Instrument that nurturing period is used and equipment are wanted to use after the strict sterilization again.The third generation housefly that evidence is cultivated in this way guarantees aseptic.

3, the kind fly that will cultivate is raised in breeding cage and lays eggs.Breeding cage is made up of gauze, the framework that supports gauze and airtight base plate.The hole of feeding is left in the side of breeding cage.The hole of feeding is stitched with cloth sleeve.Be placed with trough, drinking trough and the groove of laying eggs in the breeding cage, be placed with kind of a fly feed in the trough, be placed with a clear water and a small piece of foam in the drinking trough, stop the suction that falls, put egg-incubating material in the groove of laying eggs so that plant fly.Material of trough, drinking trough and lay eggs groove and the inside and water are changed once every day.The hole of feeding is to put fly, get ovum, change the import and export of raising tool and feed.It is 25-38 ℃ that breeding cage is placed on temperature, and relative moisture is in the environment of 60-80%.For the ease of environment is controlled, breeding cage preferably is placed in the receptacle, so that can both produce throughout the year.Receptacle can be installed fluorescent lamp, so that promote the nocturnalism of kind of fly.In order more effectively to utilize the receptacle space, be preferably in the raising frame of putting multilayer in the receptacle, breeding cage is placed on raises on the frame.Temperature adjustment, damping equipment and temperature and humidity monitoring instrument are arranged in the receptacle.

4, fly blow cultivated into larva in egg-incubating box, be fly maggot.Ovum and egg-incubating material in the groove of laying eggs that will every day takes out in the breeding cage are poured in the egg-incubating box, add the egg-incubating material of appropriate amount again, and making fly blow is that 25-38 ℃, relative moisture are to hatch into larva under the 60-80% environment naturally in temperature.For the ease of temperature and humidity is controlled, egg-incubating box should be placed in the brood chamber equally.Egg-incubating box is made by airtight material, above opening.In order to prevent that larva from climbing out of, egg-incubating box is placed on by educating in the outer box of ovum that lubricious material is made, and the outer wall of egg-incubating box is nibbled to be merged into the inwall of educating the outer box of ovum and is slidingly matched, and educates the outer box of ovum and is higher than egg-incubating box.

5, the larva in the egg-incubating box and egg-incubating material are poured in the Seperating box separate.Seperating box is sieve shape thing, and the side is airtight sheet material, upper shed, and the bottom is a net.Connect the larva of putting an airtight upper shed below the Seperating box and collect box.According to the characteristics of larva, larva specially climbs in dark, falls into larva and collects the box so can be automatically get out from the mesh of Seperating box bottom.Disengaging time is approximately 0.5-1 days, will constantly stir larva and egg-incubating material in the Seperating box around here, to accelerate separation.

6, isolated larva is carried out drying and handle, make dried maggot.

7, the kind fly in the breeding cage is replenished.Because the life-span of housefly was generally about 20 days, when the kind fly quantity in finding breeding cage reduces, then need to replenish.Method is that isolated larva is placed in the box of pupating, and the box of will pupating is again put in the breeding cage and pupated, sprouts wings into fly.

This method is that living condition, habit and the characteristics according to housefly are invented.Can guarantee and promote growth, growth and the breeding of housefly.It is aseptic to adopt cage system to guarantee, and it is concentrated to lay eggs.The setting of educating the outer box of ovum can guarantee that fly maggot do not flee.The separating method that adopts can guarantee to separate clean, thorough, and is automatic separation.If temperature and humidity is controlled at optimum state, can makes kind of fly egg laying amount reach incubation rate maximum, fly blow and reach 100%

The inventor has used two houses, an intercropping kind fly receptacle, another intercropping brood chamber, every be of a size of long * wide * high=5 * 3 * 3 meters.Receptacle is used and is raised frame and place long * wide * high=40 of breeding cages of 1 * 0.8 * 0.7 meter.Each breeding cage is raised ten thousand kind flies of 3-4, the indoor fluorescent lamp that has 100 watts.Educate the outer box of ovum and make with glass, that inwall is of a size of is long * wide * high=0.8 * 0.5 * 0.3 meter, and egg-incubating box, Seperating box, larva are collected box and all make with timber, and that the inwall size is all is long * wide * high=0.78 * 0.48 * 0.2 meter.The upper limb of educating the outer box of ovum is controlled at 38-40 ℃ with temperature controller with the upper limb local temperature, stops action when fly maggot surpasses 40 ℃, guarantees further that with this way fly maggot do not flee.The prescription of planting the fly feed is sugar, milk powder, egg liquid, and proportioning is 1: 1: 1.The amount of giving of feed is 1.5 milligrams of every every days.The prescription of egg-incubating material is wheat bran, milk powder, egg liquid, and proportioning is that wheat bran 100 gram, milk powder 3-5 gram, water are an amount of, and to hold water outlet but flowing water does not drip and is as the criterion, and this amount is supported 500 fly maggots.The temperature of receptacle and brood chamber is controlled with the electric heater of automatic temperature-control, monitors with thermometer, and humidity is controlled with electric moistening device, monitors with moisture meter.

The inventor has made test of many times to the scope of temperature and humidity, learn when temperature at 35 ℃, humidity during at 65-70%, the egg laying amount of planting fly is the highest, the incubation rate of ovum can reach 100%, 20 day and produce 17 tons of dried maggots.When temperature respectively at 25 ℃, 38 ℃, relative moisture is respectively at 60%, 80% o'clock, the egg laying amount of planting fly is minimum, the incubation rate of ovum is also minimum, dried maggot output reduces by 50%.
