The rising global demand for protein, driven by population growth, urbanization, economic development, and climate change, underscores the need for sustainable alternative protein sources. Edible insects have emerged as a viable solution to enhance foodfeed and nutritional security while contributing to waste management. This study reviews 128 peer-reviewed publications to assess consumer preferences and willingness to pay (WTP) for edible insects and their derivatives. Findings reveal that studies predominantly focus on Europe and insect-based foods, with limited research on insect-based feeds and derived products. Consumers in Africa, Asia, and Latin America show higher acceptance of insect-based food compared to those in Western nations, where psychological barriers such as neophobia, disgust, and limited awareness hinder adoption. WTP for insect-based foods varies, with some consumers willing to pay a premium while others expect lower prices than conventional options. Integrating edible insects into sustainable food and feed ssytems requires public education, innovative marketing, and scaling up production.
