Description

Technical Field

[0001] The invention belongs to the technical field of insect breeding, and in particular relates to a method for preparing a long-acting inducer for black soldier flies to lay eggs. Background Art

[0002] The collection of black soldier fly eggs is usually achieved through an odor inducer. When the black soldier flies have finished mating and laying eggs, the special smell of the inducer is used to concentrate and induce the black soldier flies to lay eggs on the egg-laying plate.

[0003] At present, most black soldier fly egg breeding manufacturers use odor inducers without a fixed formula. They mainly use the stench produced by fermentation of animal viscera or rotting fermentation of fruits and vegetables as inducers, which pollute the environment and pose serious health risks. The odor composition of the inducer is unclear, the concentration is light, and the duration is short. It cannot effectively attract adult black soldier flies to the spawning plates at designated locations to lay eggs, resulting in eggs not being laid in the designated location, and the eggs cannot be collected, causing losses. Summary of the invention

[0004] In order to solve the problem that existing odor inducers usually use fermented animal viscera or rotten fruits and vegetables, which pollute the environment and pose serious health risks, and have a light concentration and a short duration, and cannot effectively attract black soldier flies to lay eggs on an spawning plate at a designated location, the present invention provides a method for preparing a long-acting inducer for black soldier flies to lay eggs. The inducer has a long induction duration, can induce adults to lay eggs in a fixed position, is environmentally friendly, and will not affect human health.

[0005] The technical scheme of the present invention is as follows: a method for preparing a long-acting inducer for laying eggs of black soldier flies, which comprises an inducement box, dried fine residue, wheat bran, brown sugar, a microbial preparation and corpses of adult black soldier flies;

[0006] The method is as follows: firstly, 50% of dried fine residue, 25% of wheat bran, 10% of brown sugar and 5% of microbial preparation are mixed as powder and stored; then the obtained powder is fully mixed with water in a ratio of 1:1, placed in a space of 25-30°C, and aerobically fermented for 2-5 days; finally, the adult corpses of black soldier flies are added, and the ratio of the powder to the adult corpses of black soldier flies is 1:2, so as to obtain an inducer;

[0007] Place the inducer into the spawning box to induce black soldier flies to lay eggs in a concentrated manner.

[0008] Furthermore, a gauze is arranged on the top of the abortion induction box, and a stainless steel screen is arranged above the gauze.

[0009] Furthermore, the induction box has a length of 60 cm, a width of 45 cm and a height of 15 cm.

[0010] Furthermore, the gauze has a length of 80 cm and a width of 55 cm.

[0011] Furthermore, the stainless steel screen has a length of 80 cm, a width of 55 cm and a diameter of 1 mm.

[0012] Furthermore, the dried fine residue is the dried fine residue from three separations in a food waste treatment plant.

[0013] Furthermore, the microbial preparation is prepared by mixing Bacillus subtilis and lactic acid bacteria, wherein the mass fraction of Bacillus subtilis to lactic acid bacteria is one to two.

[0014] Furthermore, Bacillus subtilis ≥ 6 billion / g.

[0015] Furthermore, the lactic acid bacteria are ≥ 3 billion / g.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] (1) The present invention provides a method for preparing a long-acting inducer for black soldier flies to lay eggs. The raw materials are fermented according to the fermentation principle. The inducer prepared continuously releases the fermentation smell. The high heat evaporation during fermentation is used to release the fermentation smell and the hormone information emitted by the corpses of adult black soldier flies into the air, thereby inducing the adult black soldier flies to lay eggs in a fixed position.

[0018] (2) The effective duration of the inducer prepared by the present invention can be determined, thereby avoiding the situation where the inducer continues to be used even though it has become ineffective.

[0019] (3) In an embodiment of the present invention, an induction box is designed to carry an inducer, the gauze can prevent the eggs that are not collected cleanly from falling into the induction box after hatching, and the screen can prevent the adult black soldier flies from entering the induction box. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] Figure 1 It is a schematic diagram of the overall structure of the induced fertility box of the present invention;

[0021] In the figure: 1-induction box, 2-gauze, 3-stainless steel screen, 4-inducing agent. DETAILED DESCRIPTION

[0022] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0023] A method for preparing a long-acting inducer for black soldier flies to lay eggs, comprising an inducement box 1, dried fine residue, wheat bran, brown sugar, a microbial preparation and corpses of adult black soldier flies;

[0024] The method is as follows: firstly, 50% of dried fine residue, 25% of wheat bran, 10% of brown sugar and 5% of microbial preparation are mixed as powder and stored; then the obtained powder is fully mixed with water in a ratio of 1:1, placed in a space of 25-30°C, and aerobically fermented for 2-5 days; finally, the adult corpses of black soldier flies are added, and the ratio of the powder to the adult corpses of black soldier flies is 1:2, so as to obtain an inducer;

[0025] Place the inducer into the spawning box to induce black soldier flies to lay eggs in a concentrated manner.

[0026] Among them, when the temperature of the space is 30℃, the aerobic fermentation days are 2 days;

[0027] When the space temperature is 25℃, aerobic fermentation lasts for 5 days.

[0028] In one embodiment of the present invention, the dried fine residue is generated by a three-phase kitchen waste centrifuge.

[0029] See also Figure 1 In order to better use the prepared inducer, in another embodiment of the present invention, a gauze 2 is provided on the top of the induction box 1, and a stainless steel screen 3 is provided above the gauze 2. The induction box 1 is used to carry the inducer 4. The gauze can prevent the eggs that are not collected cleanly from falling into the induction box after hatching, and the screen can prevent the adult black soldier flies from entering the induction box.

[0030] See also Figure 1 In a specific embodiment of the present invention, the induction box has a length of 60 cm, a width of 45 cm, and a height of 15 cm; the gauze has a length of 80 cm, a width of 55 cm; the stainless steel screen has a length of 80 cm, a width of 55 cm, and a diameter of 1 mm.

[0031] When working, in the bright room of the breeding insect room, the attractant is used, and an attractant box is placed every 3 meters. Almost all the black soldier flies are concentrated on the egg-laying board to lay eggs. The egg-laying is concentrated and the breeding insects are vigorous. The random laying of black soldier flies is reduced and the yield is significantly improved. The attractant can be kept for 7 days without changing it once, reducing the number of times the egg-laying board is recovered and the use of manpower.

[0032] In one embodiment of the present invention, the dried fine residue is the dried fine residue of three-stage separation from a food waste treatment plant.

[0033] In one embodiment of the present invention, the microbial preparation is prepared by mixing Bacillus subtilis and lactic acid bacteria, wherein the mass fraction of Bacillus subtilis to lactic acid bacteria is one to two.

[0034] Based on the previous embodiment, the Bacillus subtilis in the microbial preparation is ≥ 6 billion / g.

[0035] In one embodiment of the present invention, the lactic acid bacteria in the microbial preparation are ≥ 3 billion / g.
