Checklist of edible insects and their marketability: improving rural livelihood in Imo State, Nigeria via insect consumption and marketing.

Abstract

Introduction: The consumption of edible insects (EIs) as food has been a long tradition for some populations worldwide. They are sold in markets found in the rural and urban areas of Imo State, Nigeria. Data on the economic value, marketing, and utilization of EIs are limited, particularly in Southeast Nigeria where the study was conducted. This study is necessary for the provision of data on effective marketing and utilization of EIs in order to determine their sustainability in relation to the current market system.

Methods: This study investigated the marketability of some EIs as a means of improving rural livelihood in Imo State, Nigeria. Data were collected using structured and validated questionnaires administered interpersonally to 60 respondents/EI marketers in the selected markets. Descriptive and inferential methods were employed in data analysis.

Results: The study revealed that four species of EIs were sold: Macrotermes species (35.0%), Gonimbrasia belina (30.0%), Rhynchophorus species (25.0%), and Anaphae species (10.0%), with more than one species sold by marketers (43.8%). EIs were primarily obtained from the wild (68.3%) and were sold mainly for consumption (91.7%); marketing is dominated by women (91.7%). The supply of insects is irregular and seasonality is a major constraint (51.7%). Macrotermes species (termites) had the highest significant mean quality per marketer (p < 0.05). There was a significant difference in mean quality per marketer of G. belina, Rhynchophorus, and Anaphae species (p < 0.05).

Discussion: The study concluded that EI marketing is a promising venture that needs attention. Policy intervention that will facilitate mass production/domestication of EIs and modern technical skills on harvesting is recommended.
