The black soldier fly (Hermetia illucens) is gaining increasing attention for its potential in providing a natural, renewable resource for animal and aquaculture use. With a short life cycle, high fertility, and the ability to treat organic waste, especially from livestock facilities, it offers significant economic and environmental benefits. The larvae are a rich source of protein and fatty acids for livestock and fish, and the pupae shells can be used in pharmaceuticals. The Vietnamese government has legalized the rearing of black soldier flies, and companies like Entobel are investing in large-scale production. The insect's waste treatment capabilities and potential to replace fishmeal in animal diets make it a valuable addition to the agricultural sector.
