Grasshopper production in Nigeria: Prospects, challenges, and future directions: A reviewed

The growing demand for sustainable protein sources has intensified interest in edible insects, particularly grasshoppers (Orthoptera), in Nigeria. This review aims to evaluate the potential of grasshoppers as an alternative protein source for food and feed systems. A comprehensive synthesis of existing literature was conducted, focusing on grasshopper biology, nutritional composition, production systems, economic relevance, and environmental sustainability. The findings indicate that grasshoppers are rich in high-quality protein, essential amino acids, lipids, and micronutrients, making them suitable for both human consumption and animal feeding. However, production remains largely dependent on seasonal wild harvesting, which limits scalability and commercialization. Key constraints identified include the absence of standardized domestication technologies, inadequate policy frameworks, and socio-cultural barriers affecting widespread adoption. Despite these challenges, significant opportunities exist for integrating grasshopper farming into Nigeria’s agricultural systems to enhance food security, generate income, and promote environmental sustainability. In conclusion, the development of a sustainable grasshopper production industry in Nigeria requires targeted research on mass rearing techniques, supportive policies, and increased public awareness to facilitate acceptance and commercialization.
