摘要

The global “insect apocalypse,” characterized by a rapid decline in species richness and abundance, poses a significant threat to life on Earth, as insects provide critical ecological services, including their role as food and feed. Consumption of edible insects contributes to the attainment of the sustainable development goal of eradicating hunger, ensuring food security, enhancing nutrition, and advancing sustainable agriculture. Globally, about 2000 edible insect species are consumed by humans but only a few are domesticated. However, a lack of understanding of the rearing regimes of edible insects hinders their domestication. Developing a reliable, cost-effective, and sustainable technology for the mass rearing of edible insect species could alleviate environmental strain caused by the overharvesting and foraging of the species in the wild. The study hypothesizes that transitioning from wild collection to farming can contribute substantially to the sustainability of edible insect consumption in Africa. The study reviewed aspects of the history and importance of edible insect farming. Thereafter, the study provided insight into sustainable methods for mass production of selected edible insects (The African palm larvae, grasshoppers, mopane worm, crickets, and termites), and highlighted the research needs of these insect species. Finally, the study reviewed information on the prospects of edible insect domestication and identified research gaps for future studies.
