Examples are social insects, such as ants, and especially termites, and locusts that migrate in hordes of millions of individuals. Some human societies actually utilize insects as a major source of protein . Locusts (actually grasshoppers) are used by various African groups consistently as food.
Why should insects be used as a food source?
Insects are chock -full of protein and rich in essential micronutrients , such as iron and zinc. They don’t need as much space as livestock, emit lower levels of greenhouse gases, and have a sky-high feed conversion rate: a single kilogram of feed yields 12 times more edible cricket protein than beef protein.
How are insects being used in food?
Edible insects contain high quality protein, vitamins and amino acids for humans . Insects have a high food conversion rate, e.g. crickets need six times less feed than cattle, four times less than sheep, and twice less than pigs and broiler chickens to produce the same amount of protein.
How can insects contribute to food and feed security?
One of the many ways to address food and feed security is through insect farming . Insects are everywhere and they reproduce quickly, and they have high growth and feed conversion rates and a low environmental footprint over their entire life cycle. They are nutritious, with high protein, fat and mineral contents.
