Description

Technical Field

[0001] This application relates to the field of black soldier fly egg transportation, and in particular to a method for long-distance transportation of black soldier fly eggs. Background Technology

[0002] Black soldier flies are saprophytic insects belonging to the family genus *Strombidae*. They feed on livestock manure and household waste, producing high-value animal protein feed. Due to their rapid reproduction, large biomass, wide range of diets, high absorption and conversion rates, ease of management, low feeding costs, and good palatability to animals, they are utilized as a resource insect. They have become a resource insect on par with fly larvae, mealworms, and superworms, and have been promoted worldwide. They are widely used in the treatment of waste such as chicken manure, pig manure, and kitchen waste.

[0003] Currently, there is a huge demand for black soldier flies in both production and daily life. Therefore, to meet this massive demand, black soldier flies are mainly produced through centralized breeding and then transported to various parts of the country. The black soldier fly process household waste during its larval stage, which lasts only 15 days. Therefore, to improve processing efficiency, the eggs are usually transported to their destination before hatching.

[0004] Currently, in summer, black soldier fly eggs are mainly transported using cardboard boxes with ventilation holes, or foam boxes with ice packs. In winter, foam containers are typically used. However, during hot or cold seasons, cardboard boxes and foam containers are not effective at controlling temperature, causing drastic temperature changes that lead to the death of some eggs and a reduced hatching rate. While a temperature-controlled system could be used, it requires specialized vehicles with temperature-controlled compartments, which is restrictive and significantly increases costs. Summary of the Invention

[0005] To address the problem that black soldier fly eggs are easily killed by drastic temperature changes during transportation, this application provides a method for long-distance transportation of black soldier fly eggs.

[0006] This application provides a method for long-distance transportation of black soldier fly eggs, which employs the following technical solution:

[0007] A method for long-distance transportation of black soldier fly eggs, the method comprising: placing insulation boards against the five inner walls of a foam box; loading black soldier fly eggs and bedding material into the egg box; sealing the ventilation holes on the egg box with breathable gauze; placing the egg box in the foam box; then placing the insulation boards on top of the egg box, forming a receiving space between the insulation boards on the inner wall of the foam box and the insulation boards on top of the egg box; the egg box being located within the receiving space; then closing the lid to seal the foam box before transportation.

[0008] The insulation board is placed in a sealed bag, and the insulation board is composed of 73% to 75% butyl stearate, 18% to 20% ethylene butyl ester, 2% to 3% tripalmitoylglycerol, 2% to 3% trimyristic glycerol, and 1% to 3% 1,3-2,4-di(3,4-dimethyl)benzylsorbitol by weight percentage.

[0009] By adopting the above technical solution, the problem of black soldier fly eggs being easily affected by changes in ambient temperature and thus reducing their hatching rate can be improved. The insulation board prepared in this application has a phase change temperature range of 17-22℃, exhibiting excellent heat insulation effect. It can maintain a stable temperature inside the foam box, thereby protecting the black soldier fly eggs. The insulation board is normally solid, with 1,3-2,4-di(3,4-dimethyl)benzylsorbitol acting as a nucleating agent. The insulation board can isolate heat, reduce heat conduction between the foam box and the outside, and keep the temperature inside the foam box within a suitable range for black soldier fly eggs. When the temperature inside the foam box exceeds the phase change temperature of the insulation board, the insulation board transforms into a liquid state and absorbs the heat inside the foam box. At this time, the liquid insulation material forms a liquid bag inside the sealing strip, which can still play a heat insulation role and still protect the black soldier fly eggs.

[0010] This application utilizes the inherent heat insulation and thermal insulation properties of foam material, combined with the thermal insulation board installed on the inner wall of the foam box, to greatly improve the heat insulation performance of the foam box, giving it a better temperature control effect and slowing down temperature changes within the foam box. In addition, the bedding material in the egg box has good air permeability and cushioning effect, which can significantly improve the hatching rate of black soldier fly eggs.

[0011] Preferably, the bedding material is one or a combination of several of the following: sawdust, shavings, rice straw, rice straw powder, puffed corn flour, alfalfa, wheat bran, and timothy hay.

[0012] Preferably, the bedding material is a mixture of sawdust, rice straw powder, and rice straw. The sawdust and rice straw powder are mixed evenly and used as the lower bedding material. The weight percentage of sawdust in the lower bedding material is 20% to 50%. The rice straw is laid on the mixture of sawdust and rice straw powder as the upper bedding material. The upper bedding material completely covers the lower bedding material. The black soldier fly eggs are mixed in the lower bedding material.

[0013] Preferably, the weight ratio of sawdust to straw powder in the lower bedding material is 1:1.

[0014] Experiments have shown that using this proportion of bedding material is beneficial for improving the hatching rate of black soldier fly eggs.

[0015] Preferably, the weight of the black soldier fly eggs is 1.5 to 4 times the weight of the underlying bedding material.

[0016] By adopting the above technical solution, the lower bedding material has a cushioning and shock-absorbing effect on black soldier fly eggs, which is beneficial to protecting the black soldier fly eggs. When the weight of the black soldier fly eggs exceeds four times the weight of the lower bedding material, the lower bedding material is too little relative to the black soldier fly eggs, the cushioning and shock-absorbing effect is reduced, and if there are too many black soldier fly eggs in the foam box, the oxygen content will be consumed in large quantities, resulting in a decrease in the hatching rate of black soldier fly eggs.

[0017] Preferably, the foam box contains one or two layers of egg boxes arranged in a rectangular array, and the number of egg boxes in the bottom layer is denoted as M. Where [X] represents rounding, A is the length of the long side of the bottom surface inside the foam box, A≤70cm, B is the length of the short side of the bottom surface inside the foam box, B≤50cm, d is the thickness of the insulation board, 1cm≤d≤5cm, and the height of the internal space of the foam box is 22~25cm.

[0018] When the foam box contains two layers of egg boxes, the number of egg boxes in the upper layer is denoted as N. or The upper and lower egg boxes are placed alternately.

[0019] Experiments have shown that controlling the amount of black soldier fly eggs placed in this way can achieve optimal economic benefits in egg transportation while also reducing egg loss during transportation.

[0020] In summary, this application includes at least one of the following beneficial technical effects:

[0021] 1. This application uses a foam box with good heat insulation and heat preservation properties as a transport container, and sets a heat preservation board on the inner wall of the foam box, which greatly improves the heat insulation and heat preservation performance of the foam box, and makes the foam box have a better temperature control effect. It can delay the temperature change in the foam box. Combined with the good air permeability and pressure buffering characteristics of the bedding material in the insect egg box, it can significantly improve the hatching rate of black soldier fly eggs.

[0022] 2. By controlling the amount of black soldier fly eggs placed, this application can achieve optimal economic benefits in transporting the eggs while reducing the loss of eggs during transportation. Attached Figure Description

[0023] Figure 1 This is a schematic diagram of the placement of the insect egg box in Embodiment 1 of this application. Detailed Implementation

[0024] To facilitate a better understanding of the technical solutions of this application, the following detailed description of this application is provided in conjunction with tables and embodiments, but this is not intended to limit the scope of protection of this application.

[0025] Example 1

[0026] Methods for long-distance transportation of black soldier fly eggs:

[0027] Black soldier fly eggs and bedding material are placed into egg boxes, and the ventilation holes on the egg boxes are sealed with breathable gauze to prevent leakage of bedding material or black soldier fly eggs. In this embodiment, rice straw is used as bedding material, and the weight of black soldier fly eggs in each egg box is 35g. The rice straw is laid on top of the black soldier fly eggs and completely covers them.

[0028] Insulation boards are placed against the five inner walls of a foam box, and the insulation boards are placed in sealed plastic bags. The insect egg boxes are then placed inside the foam box in two layers, arranged in a rectangular array. The number of insect egg boxes in the bottom layer is denoted as M. The number of egg boxes in the upper layer is denoted as N. or Where [X] represents rounding, A is the length of the long side of the bottom surface inside the foam box, A≤70cm, B is the length of the short side of the bottom surface inside the foam box, B≤50cm, d is the thickness of the insulation board, 1cm≤d≤5cm, and the height of the internal space of the foam box is 22~25cm.

[0029] In this embodiment, A is 37cm, B is 27cm, d is 1.5cm, the height of the internal space of the foam box is 22cm, M is 6, N is 3, the diameter of the insect egg box is 8cm, and the height is 7cm. The upper and lower insect egg boxes are placed alternately, as shown below. Figure 1 As shown, the lower layer of egg boxes is arranged in a 2*3 matrix, and the upper layer of egg boxes is arranged in a 1*3 matrix.

[0030] Then, place an insulation board on top of the egg box. The insulation board is placed in a sealed plastic bag. The insulation boards on the inner wall of the foam box and the insulation board on top of the egg box abut against each other to form a sealed containment space. The egg box is located in the containment space.

[0031] After placing the insect egg box, close the lid and seal the gaps at the lid of the foam box with tape before transporting it.

[0032] In this embodiment, the insulation board is composed of 73% butyl stearate, 20% ethylene butyl ester, 3% tripalmitic acid glyceride, 3% trimyristic acid glyceride, and 1% 1,3-2,4-di(3,4-dimethyl)benzylsorbitol by weight percentage.

[0033] The preparation method of the insulation board is as follows: mix butyl stearate, ethylene butyl ester, tripalmitoyl glycerol and trimyristoyl glycerol and heat to 85±5℃, stir for 1 hour until the mixture is uniform, then add 1,3-2,4-di(3,4-dimethyl)benzylidene sorbitol, continue stirring for 30 minutes, pour into a mold, cool and solidify, and then demold.

[0034] The resulting insulation board has a phase change temperature of 17-22℃. When applied, it can maintain the internal temperature of the foam box at 17-22℃. When the internal temperature of the foam box exceeds 22℃, the insulation board changes from solid to liquid, but it will not spill out of the sealed plastic bag. The fluid insulation material can still play a role in heat insulation and continuously protect the black soldier fly eggs.

[0035] It should be noted that in the embodiments and comparative examples of this application, the bedding material includes both powdered and straw-based materials, depending on the actual selection. When the bedding material consists only of powdered material, the powdered material is mixed evenly with the black soldier fly eggs, and the total weight is controlled to be 50g. When the bedding material consists only of straw-based material, 35g of black soldier fly eggs are placed in each egg box, and the straw-based material is spread on top of the black soldier fly eggs, completely covering them. When the bedding material includes both powdered and straw-based materials, the total weight of the black soldier fly eggs and powdered material in each egg box is controlled to be 50g, and they are mixed evenly, with the straw-based material covering the mixture of black soldier fly eggs and powdered material.

[0036] It should be noted that in the embodiments and comparative examples of this application, rice straw, alfalfa, and timothy hay are straw-like bedding materials, while sawdust, rice straw powder, puffed corn flour, bran, and wood shavings are powder-like bedding materials. Puffed corn flour refers to starch gelatinized from corn under the combined effects of moisture, heat, mechanical shearing, friction, kneading, and pressure difference. It has a light yellow appearance and a fluffy texture. Puffed corn flour is common knowledge and will not be described in detail in this embodiment.

[0037] Example 2

[0038] The difference from Example 1 is that the bedding material is puffed corn flour, the weight of black soldier fly eggs in the egg box is 35g, the weight of puffed corn flour is 15g, and the puffed corn flour and black soldier fly eggs are mixed evenly.

[0039] Example 3

[0040] The difference from Example 1 is that the bedding material is rice straw powder, which is mixed evenly with black soldier fly eggs. The weight of black soldier fly eggs in the egg box is 35g, and the weight of rice straw powder is 15g. The rice straw powder and black soldier fly eggs are mixed evenly.

[0041] Example 4

[0042] The difference from Example 1 is that the bedding material is wheat bran, the weight of black soldier fly eggs in the egg box is 35g, the weight of wheat bran is 15g, and the wheat bran and black soldier fly eggs are mixed evenly.

[0043] Example 5

[0044] The difference from Example 1 is that the bedding material is wood chips, the weight of the black soldier fly eggs in the egg box is 35g, the weight of the wood chips is 15g, and the wood chips and black soldier fly eggs are mixed evenly.

[0045] Example 6

[0046] The difference from Example 1 is that the bedding material is wood shavings, the weight of black soldier fly eggs in the egg box is 35g, the weight of wood shavings is 15g, and the wood shavings and black soldier fly eggs are mixed evenly.

[0047] Example 7

[0048] The difference from Example 1 is that alfalfa was used as bedding material, the weight of black soldier fly eggs in the egg box was 35g, and alfalfa was used to cover the black soldier fly eggs.

[0049] Example 8

[0050] The difference from Example 1 is that the bedding material is timothy grass, the weight of the black soldier fly eggs in the egg box is 35g, and the timothy grass covers the top of the black soldier fly eggs.

[0051] Referring to Examples 1-8, Examples 9-16 were set up. The only difference between Examples 9-16 and Examples 1-8 is that the insulation board is composed of 75% butyl stearate, 18% ethylene butyl ester, 2% tripalmitoyl glycerol, 2% trimyristic glycerol, and 3% 1,3-2,4-di(3,4-dimethyl)benzyl sorbitol by weight percentage.

[0052] The verification experiment used Examples 1-8 as a reference and set up Comparative Examples 1-8. The only difference between Comparative Examples 1-8 and Examples 1-8 is that cardboard boxes with holes were used for transportation in summer, and foam boxes without insulation boards were used for transportation in winter.

[0053] With reference to Examples 1-8, Comparative Examples 9-16 were set up. The only difference between Comparative Examples 9-16 and Examples 1-8 is that foam boxes were used for summer transportation, and ice packs were placed inside the foam boxes. Winter tests were not conducted.

[0054] Examples 1-16 and Comparative Examples 1-8 were transported for 3 days in summer (August) and winter (December), respectively. Comparative Examples 9-16 were transported for 3 days only in summer (August). The transport test was conducted with Nanning City, Guangxi Province as the origin and Zunyi City, Guizhou Province as the destination. Each example and comparative example was tested in three parallel sets.

[0055] Examples 1-16 and Comparative Examples 1-16 were all synchronous tests, that is, transport tests were conducted on the same vehicle at the same time. The temperature range of the entire test process was: 26-40℃ in summer and -2-8℃ in winter.

[0056] Hatching rate calculation:

[0057] Black soldier fly larvae single-gram experimental egg count determination: 30 portions of eggs of different sizes were weighed, each portion containing 2 mg (accurate to 0.1 mg), placed in a petri dish, and soaked in alcohol to disperse them. After observation, if there was no overlap, the eggs were photographed and counted. It was estimated that the number of black soldier fly larvae per gram was approximately 40,000 eggs / g.

[0058] After the black soldier fly eggs were transported to their destination, one box containing bedding material was taken from each parallel experiment and placed into different large plastic boxes. Chicken feed was added, and the eggs were incubated for 7 days under a constant temperature and humidity environment (temperature controlled at 28℃, humidity controlled at 65%). After the incubation period, the plastic boxes were removed, the number of larvae was counted, and the hatching rate was calculated. The hatching rate was calculated as: number of larvae hatched per box / (mass of eggs per box × number of eggs per gram). Specific data are shown in Table 1.

[0059] Table 1: Bedding composition and black soldier fly egg hatching rate in Examples 1-16 and Comparative Examples 1-16

[0060]

[0061]

[0062] Based on the data from Examples 1-16, Comparative Examples 1-16, and Table 1, it can be seen that the transportation method of this application can significantly improve the hatching rate of black soldier fly eggs. Compared with the method of punching holes in cardboard boxes and placing ice packs inside foam boxes in summer, and the method of using ordinary foam boxes in winter, the hatching rate of black soldier fly eggs in the embodiments of this application is significantly improved. This indicates that the insulation board has a good temperature control effect in both summer and winter, which helps to stabilize the temperature inside the foam box, thereby improving the hatching rate of black soldier fly eggs.

[0063] Comparing the data from Examples 1-16, it can be seen that the hatching rate of black soldier fly eggs in Examples 9-16 is slightly higher than that in Examples 1-8, indicating that the insulation board with the material ratio in Examples 9-16 is more conducive to improving the hatching rate of black soldier fly eggs.

[0064] Example 17

[0065] The difference from Example 9 is that the bedding material is a mixture of bran and sawdust with a weight ratio of 1:1. The weight of the black soldier fly eggs in the egg box is 35g, the weight of the bedding material is 15g, and the bedding material and black soldier fly eggs are mixed evenly.

[0066] Example 18

[0067] The difference from Example 9 is that the bedding material is a mixture of wheat bran and rice straw powder, with a weight ratio of wheat bran to rice straw powder of 1:1. The weight of black soldier fly eggs in the egg box is 35g, and the weight of the bedding material is 15g. The bedding material and black soldier fly eggs are mixed evenly.

[0068] Example 19

[0069] The difference from Example 9 is that the bedding material is a mixture of sawdust and rice straw powder, with a weight ratio of sawdust to rice straw powder of 1:1. The weight of black soldier fly eggs in the egg box is 35g, the weight of the bedding material is 15g, and the bedding material and black soldier fly eggs are mixed evenly.

[0070] Example 20

[0071] The difference from Example 9 is that the bedding material is made of bran and straw, the weight of black soldier fly eggs in the egg box is 35g, the weight of bran is 15g, the bran and black soldier fly eggs are mixed evenly, and the straw is placed on top of the mixture of bran and black soldier fly eggs.

[0072] Example 21

[0073] The difference from Example 9 is that the bedding material is made of sawdust and straw, the weight of black soldier fly eggs in the egg box is 35g, the weight of sawdust is 15g, the sawdust and black soldier fly eggs are mixed evenly, and the straw is placed on top of the mixture of sawdust and black soldier fly eggs.

[0074] Example 22

[0075] The difference from Example 9 is that the bedding material is made of sawdust, rice straw powder, and rice straw. A mixture of sawdust and rice straw powder is used as the lower bedding material, with a weight ratio of sawdust to rice straw powder of 1:1. The weight of black soldier fly eggs in the egg box is 35g, and the weight of the lower bedding material is 15g. The lower bedding material and black soldier fly eggs are mixed evenly, and rice straw is placed on top of the mixture of the lower bedding material and black soldier fly eggs.

[0076] Example 23

[0077] The difference from Example 9 is that the bedding material is made of sawdust, rice straw powder, and alfalfa. A mixture of sawdust and rice straw powder is used as the lower bedding material, with a weight ratio of sawdust to rice straw powder of 1:1. The weight of black soldier fly eggs in the egg box is 35g, and the weight of the lower bedding material is 15g. The lower bedding material and black soldier fly eggs are mixed evenly, and alfalfa is placed on top of the mixture of the lower bedding material and black soldier fly eggs.

[0078] Control groups 1-5 were set up. Control group 1 was the same as Example 4, control group 2 was the same as Example 5, control group 3 was the same as Example 3, control group 4 was the same as Example 1, and control group 5 was the same as Example 7.

[0079] The control groups 1-5 and examples 17-23 were tested according to the test methods and conditions described above. Three parallel tests were conducted for each example and control group. The specific data are shown in Table 2.

[0080] Table 2: Bedding composition and black soldier fly egg hatching rate in control groups 1-5 and examples 17-23

[0081]

[0082]

[0083] Combining the data from control groups 1-5, examples 17-23, and Table 2, it can be seen that the selection of different bedding materials also affects the hatching rate of black soldier fly eggs. Compared with using a single type of bedding material, using a mixture of different types of bedding materials is beneficial to improving the hatching rate of black soldier fly eggs. Among them, the bedding material with the ratio in example 22 is better because sawdust and rice straw powder are powdered bedding materials that can be fully mixed with black soldier fly eggs, reducing the problem of moisture loss from the eggs and thus improving the hatching rate. Rice straw also has a certain heat insulation effect, which can effectively prevent the eggs from freezing or overheating.

[0084] Example 24

[0085] The difference from Example 22 is that the weight percentage of wood chips in the lower bedding material is 20%.

[0086] Example 25

[0087] The difference from Example 22 is that the weight percentage of wood chips in the lower bedding material is 40%.

[0088] Example 26

[0089] The difference from Example 22 is that the weight percentage of wood chips in the lower bedding material is 60%.

[0090] A control group 6 was set up, which was the same as that in Example 22.

[0091] The control group 6 and Examples 24-26 were tested according to the test methods and conditions of the above verification test. Three parallel tests were conducted for each control group and example. The specific data are shown in Table 3.

[0092] Table 3: Bedding ratio and black soldier fly egg hatching rate in control group 6 and Examples 24-26

[0093]

[0094] Wood chips are lightweight and fluffy, which reduces frictional heat between insect eggs, while rice straw powder has a certain weight and contains beneficial microorganisms, which can improve the heat tolerance of black soldier fly eggs. In winter, both wood chips and rice straw powder have a heat-insulating effect, which can reduce cold damage to insect eggs, and the beneficial microorganisms can improve the biological activity of insect eggs during the breeding process.

[0095] As can be seen from the data in Table 3, when the weight ratio of sawdust to rice straw powder is 1:1, it can effectively inhibit the hatching of black soldier fly eggs during transportation and reduce the loss of moisture from the black soldier fly eggs, thereby improving the hatching rate of black soldier fly eggs. Therefore, the weight ratio of sawdust to rice straw powder in the lower bedding material of Example 22 is more optimal.

[0096] Example 27

[0097] The difference from Example 22 is that the weight of the black soldier fly eggs in the egg box is 30g, the weight of the lower bedding material is 20g, and the weight ratio of black soldier fly eggs to lower bedding material is 1.5:1.

[0098] Example 28

[0099] The difference from Example 22 is that the weight of the black soldier fly eggs in the egg box is 33.3g, the weight of the lower bedding material is 16.7g, and the weight ratio of black soldier fly eggs to lower bedding material is approximately 2:1.

[0100] Example 29

[0101] The difference from Example 22 is that the weight of the black soldier fly eggs in the egg box is 38.5g, the weight of the lower bedding material is 11.5g, and the weight ratio of black soldier fly eggs to lower bedding material is approximately 3.3:1.

[0102] Example 30

[0103] The difference from Example 22 is that the weight of the black soldier fly eggs in the egg box is 40g, the weight of the lower bedding material is 10g, and the weight ratio of black soldier fly eggs to lower bedding material is 4:1.

[0104] Example 31

[0105] The difference from Example 22 is that the weight of the black soldier fly eggs in the egg box is 42g, the weight of the lower bedding material is 8g, and the weight ratio of black soldier fly eggs to lower bedding material is 5.25:1.

[0106] A control group 7 was set up, which was the same as that in Example 22.

[0107] The control group 7 and Examples 27-31 were tested according to the test methods and conditions of the above verification test. Three parallel tests were conducted for each control group and example. The specific data are shown in Table 4.

[0108] Table 4: Bedding ratio and black soldier fly egg hatching rate in control groups 7 and 27-31

[0109]

[0110] Combining the data from control groups 7, 27-31 and Table 4, it can be seen that when a 1:1 mixture of sawdust and rice straw powder is used as the lower bedding material and rice straw as the upper bedding material, the weight ratio of black soldier fly eggs to the lower bedding material affects the hatching rate of black soldier fly eggs. As the weight ratio of black soldier fly eggs to the lower bedding material increases, the hatching rate of black soldier fly eggs shows a trend of first increasing and then decreasing. This is because the powdery lower bedding material has a cushioning and shock-absorbing effect on the black soldier fly eggs. When the amount of black soldier fly eggs increases and the amount of lower bedding material decreases, the cushioning and shock-absorbing effect on the black soldier fly eggs weakens, thus causing a decrease in the hatching rate. However, when there are too few black soldier fly eggs and too much bedding material, it will compress the eggs, hindering airflow between the material and the eggs, thus reducing the hatching rate of the eggs.

[0111] When the weight of black soldier fly eggs exceeds four times the weight of the lower bedding material, the hatching rate of the black soldier fly eggs decreases significantly. This is because the lower bedding material is too little relative to the black soldier fly eggs, reducing its cushioning and shock absorption effect. In addition, the excessive number of black soldier fly eggs in the foam box increases the friction between the eggs, leading to a decrease in the hatching rate of the black soldier fly eggs.

[0112] As can be seen from the data in Table 4, the weight ratio of insect eggs to the underlying bedding material in Example 29 is approximately 3.3:1, which is more effective in improving the hatching rate of black soldier fly eggs.

[0113] Comparative Example 17

[0114] The difference from Example 29 is that cardboard boxes with holes are used for summer transportation, and foam boxes without insulation boards are used for winter transportation.

[0115] Comparative Example 18

[0116] The difference from Example 29 is that the black soldier fly egg box does not contain bedding material.

[0117] A control group 8 was set up, which was the same as that in Example 29.

[0118] The control group 8 and comparative examples 17-18 were tested according to the test methods and conditions of the above verification test. Each control group and comparative example was tested in three parallel groups. The specific data are shown in Table 5.

[0119] Table 5: Hatching rate of black soldier fly eggs in control group 8 and comparative examples 17-18

[0120]

[0121] Based on the data from control group 8, comparative examples 17-18, and Table 5, it can be seen that using only the weight ratio of black soldier fly eggs to bedding or the bedding ratio in Example 29 has a limited effect on improving the hatching rate of black soldier fly eggs. It is evident that there is a synergistic effect between the weight ratio of black soldier fly eggs to bedding and the bedding ratio in Example 29 and the foam box with insulation board in the embodiments of this application. The combination of the two can greatly improve the hatching rate of black soldier fly eggs.

[0122] Example 30

[0123] The difference from Example 29 is that in the foam box, there are 6 lower layer egg boxes arranged in a 2*3 matrix, and 4 upper layer egg boxes arranged in a 2*2 matrix, with the upper and lower layer egg boxes placed alternately.

[0124] A control group 9 was set up, which was the same as that in Example 29.

[0125] Three parallel experiments were conducted on control group 9 and Example 30 according to the verification test method described above. The specific data are shown in Table 6.

[0126] Table 6: Hatching rate of black soldier fly eggs in control group 9 and example 30

[0127]

[0128] As can be seen from the data in Table 6, the hatching rate of black soldier fly eggs in Example 30 was lower than that in Control Group 9. This is because the number of egg boxes in Example 30 was greater than that in Control Group 9. Within a limited space, considering the size of the egg boxes and the environment in which the eggs are placed, fewer egg boxes result in less oxygen consumption in the foam boxes, which is better for egg transportation. However, from an economic perspective, fewer foam boxes per box lead to higher production costs, which does not meet actual production needs. Therefore, according to the egg box placement density control of this application, the upper and lower egg boxes are placed alternately. This placement satisfies the egg survival environment requirements while maximizing transportation efficiency.

[0129] In summary, the transportation method proposed in this application can significantly improve the hatching rate of black soldier fly eggs. By using a foam box with insulating material and a specific bedding ratio, and by controlling the number of egg boxes placed in the foam box, the impact of different regions and climates on the black soldier fly eggs during transportation is reduced. This makes the black soldier fly eggs less susceptible to drastic temperature changes during transportation, and shows great promise for application.

[0130] This specific embodiment is merely an explanation of this application and is not intended to limit it. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of this application.
