Embodiment 1

[0025] A kind of artificial feeding method that increases black soldier fly biomass comprises the following steps:

[0026] S1) The preparation steps of the mulberry flavonoid aqueous solution are as follows: Weigh 0.5 g of the mulberry flavone and dissolve it in 1 L of water to prepare a flavonoid aqueous solution with a concentration of 0.5 g / L.

[0027] S2) The artificial breeding method of black soldier flies comprises the following steps:

[0028] A. Connect 0.1g of black soldier fly eggs to the mixture of bran and corn flour: in a mixed system with a special feed of 1:3 (mass ratio), hatch at a temperature of 27.0°C and a humidity of 60%;

[0029] B. After the hatching is completed, continue to feed the black soldier fly larvae in the system, and use a 5-mesh sieve to separate the 5-day-old larvae from the insect sand (that is, the mixture of material residue and insect excrement) after 5 days;

[0030] C, air-dried chicken manure is carried out 16 order sieves;

Abstract

The invention discloses an artificial breeding method for increasing the biomass of hermetia illucens larvae. The method comprises the following steps of inoculating hermetia illucens eggs into an incubation material of bran corn flour and special feed, incubating, and continuously culturing in a system to obtain larvae; and then transferring the larvae into a larva material, added with flavonoidcompounds, of chicken manure and the bran corn flour, and continuously culturing until prepupae appear and harvesting the larvae. According to the method, the flavonoid compounds are added in the hermetia illucens breeding process, more nutrient substances in the materials are converted into self substances, and therefore hermetia illucens larva biomass accumulation can be remarkably increased. The method is simple, effective and easy to operate, the problem of conversion rate limitation in the current hermetia illucens composting technology is solved, and favorable conditions are created forpopularization and application of the hermetia illucens technology.

Description

technical field [0001] The invention belongs to the field of insect breeding / biotechnology, and in particular relates to an artificial breeding method for increasing the biomass of black soldier flies. Background technique [0002] The black soldier fly belongs to the Diptera Soldier Fly family, also known as the bright-spotted flat-horned soldier fly, which originated in tropical, subtropical and temperate regions of America, and is now widely distributed in tropical and warm temperate regions. In my country, the distribution of black soldier flies is more in North China, South China and the southeast coastal areas, and less in other areas, and the regional distribution is uneven. Since the black soldier fly can effectively convert organic waste into its own biomass, which reduces environmental pollution and improves resource utilization, the resource advantages of the black soldier fly have been gradually tapped in recent years and more and more applications have been made...
