Soldier flies as protein source for animal food

11 July 2019, Mecklenburg-Western Pomerania, Dummerstorf: At the Leibniz Institute for Farm Animal Biology (FBN), biologist Mielenz shows a "bioball" in the fly cage of the first soldier fly colony in which the flies lay their eggs. The scientists are investigating whether and how the up to two centimetre large black soldier flies and their protein-rich larvae can be used as a high-quality protein source for animal feed.
