[0018] Example 1
[0019] After the horse dung is cleared from the horse farm, the horse dung is crushed with a crusher to make it thicker to 2 mm, and then an appropriate amount of nutritive auxiliary materials (see Table 1) are added, mixed evenly, and prepared as a culture material. Pour the culture material into the corresponding container, the height of the culture material is 4cm, and insert an appropriate amount of black water fly eggs on the surface of the culture material, the density of the eggs is: 0.2g black water fly eggs / kg culture material. The culture temperature was 30°C, and the black water fly eggs hatched into larvae on the second day, and began to decompose and transform the culture material. On the 18th day, put a larger container outside the culture container and sprinkle dry rice bran powder into it to facilitate the collection of mature black water fly maggots. After 20 to 30 days, the black horsefly larvae have reached the mature state, and they have cr...

[0023] Example 2
[0024] After the horse manure is cleared from the horse farm, the horse manure is crushed with a crusher to make it thicker than 3mm, and then an appropriate amount of nutritive auxiliary materials (see Table 2) are added, mixed evenly, and prepared into a culture material. Pour the culture material into the corresponding container, the height of the culture material is 6cm, and insert an appropriate amount of black water fly eggs on the surface of the culture material, the density of the eggs is: 0.6g black water fly eggs / kg culture material. The culture temperature was 25°C, and the black water fly eggs hatched into larvae on the second day, and began to decompose and transform the culture material. Properly supplement water during the cultivation process to prevent excessive temperature rise. On the 18th day, put a larger container outside the culture container, and sprinkle dry rice bran powder in it to facilitate the collection of mature black fly larvae...

[0027] Example 3
[0028] After the horse manure is cleared from the horse farm, the horse manure is crushed with a crusher to make it thicker to 5mm, and then an appropriate amount of nutrient auxiliary materials (see Table 3) are added, mixed evenly, and prepared as a culture material. Pour the culture material into the corresponding container, the height of the culture material is 8cm, and insert an appropriate amount of black water fly eggs on the surface of the culture material, the density of the eggs is: 0.8g black water fly eggs / kg culture material. The culture temperature was 25°C, and the black water fly eggs hatched into larvae on the second day, and began to decompose and transform the culture material. Properly supplement water during the cultivation process to prevent excessive temperature rise. On the 18th day, put a larger container outside the culture container, and sprinkle dry rice bran powder into it to facilitate the collection of mature larvae of the black...
