Abstract Summing up all that has been studied thoroughly, we found that there is a significant effect of the type of feeding media used to feed the larvae on the biological rates of the insect, the longevity of adults, the sex ratio between males and females, and the number of eggs laid by each female. The duration of the larvae was not affected by the type of food used, and the best feeding media here was the media (D), the environment of organic kitchen waste free from any source of animal protein. The effect of the type of feeding media on the bacterial community of the larvae’s intestines was also extended, as there was a difference between the types of bacteria that were isolated from the larvae’s intestines among the four groups of larvae. While the fungal community inside the intestine of the larvae had a great deal of similarity among the four different groups of larvae, despite the different feeding media on which the larvae fed. Likewise, these fungi were useful and important for the insect to digest and break down the pathogenic bacteria present in the food environment that the larvae fed on, as well as digest and break down the toxic substances secreted by harmful fungi and bacteria in feeding media that are considered organic waste. Also, analysis of the nutrients of the bodies of the black soldier fly larvae proved that they are rich in protein, fats, and fiber important for human and animal health, as well as the ability of the larvae to rid the environment of huge amounts of organic waste that pollutes the environment and is a fertile source for bacteria, fungi, and emissions harmful to the environment, which in turn affects human, animal, and soil health. . Finally, when calculating the food conversion rates and growth performance of the black soldier fly larvae, it became clear that the wealth we possess without sufficient awareness of its importance in treating organic waste and converting it into a rich source of protein and other nutrients needed by humans and animals at the lowest possible costs. Finally, the following can be recommended: • In conjunction with the fodder crisis that Egypt is going through recently, which strongly affects poultry trade and prices, we recommend the establishment of farms for the production of black soldier fly larvae on a large scale. • We recommend the existence of production units for black soldier fly larvae inside poultry farms feeding on the organic waste of the farm to reduce environmental pollution and maximize the use of all farm outputs by recycling these wastes. • We recommend the use of black soldier fly larvae as food for fish by establishing larvae rearing units inside fish farms, as mentioned in the previous point. |
