Habitat-centric versus species-centric approaches to edible insects for food.
The current paradigm of the edible insects for food and feed industry uses a species-centric approach in which an insect species is chosen first and development of rearing practices follows. The goal is to optimize production to maximize the yield of that species in that facility. In contrast, the habitat-centric approach first chooses a habitat, either natural or artificial, then develops harvesting or rearing protocols within that habitat. The goal of this approach is to maximize the yield derived from that habitat. The habitat-centric approach eliminates potential threats from invasive species, and can repurpose local food and agricultural waste into protein derived from local insect species. This approach can increase food security by increasing the diversity of insects that are mass-produced. The species-centric and habitat-centric approaches address different issues and offer advantages in different situations. Further development of the edible insect industry will likely use a combination of both approaches.
