Pooja Meena, Shashi Meena
Edible orthopteran insects are a potential source of nutrition as food and feed for humans and livestock with a great promise of food security. Worldwide, consumption of insects belonging the order Orthoptera is known since prehistoric time, but lack of knowledge of their nutritional quality and occurrence limit their utilization for consumption or inclusion into other food sources. Orthopteran insects are well distributed all over the world due to the frequent acquiescence in the terrestrial environment. Owing to orthopteran’s large size and easy rearing process contribute their essence in a nutritional means for both humans as well as other animals. The family Acrididae plays an incredibly key role in orthopteran entomophagy having elevated variations in grasshopper and locust species and their well distribution in all type of the habitats. This review aims to provide the database of the distribution of edible orthopteran insects in different geographic regions (Nearctic, Neotropical, Palearctic, Oriental, African and Australian) of the world and their nutritional contents based on the published literature. The information on the distribution, nutritional advantage and food security of various edible orthopteran species for the future generation is very well highlighted. The paper explored the use of individuals of the order Orthoptera for livestock feed, contribution to economic development and livelihood improvement.
