This study estimated poultry farmers’ willingness to pay (WTP) for fly larvae meal as animal protein source to feed local chickens in Benin. A double-bounded contingent valuation approach was used to collect data from 480 poultry farmers, and an interval regression model was performed. We found that 82.10% of poultry farmers are willing to pay for using fly larvae meal. The average WTP was estimated at FCFA/ kg 225.10 (€/kg 0.34), indicating a potential and reliable demand in fly larvae meal. Our analysis suggests that public actions can sensitize poultry farmers and support innovative small companies to produce and market fly larvae meal.
