Knowledge, Attitudes, Perceptions and Consumption of Edible Insects at the University of Venda: A Descriptive...

Background: Edible insects constitute a highly nutritious, environmentally sustainable and culturally significant food resource with considerable potential to contribute to food system transformation within academic and broader societal contexts. Although global interest in entomophagy continues to increase, there remains limited research exploring the knowledge, perceptions, attitudes and consumption practices of university populations within rural South African settings. Methods: Three concurrent cross-sectional quantitative studies were conducted at the University of Venda (UNIVEN), located in Thohoyandou, Vhembe District, Limpopo Province, South Africa. Study 1 evaluated the knowledge, attitudes and consumption patterns of edible insects among 200 students. Study 2 examined knowledge and utilisation of edible insects among 390 students. Study 3 investigated knowledge and perceptions regarding edible insects among 200 university staff members. Structured questionnaires covering socio-demographic characteristics, knowledge, perceptions, attitudes and food frequency practices were administered across all studies. Data analysis was performed using SPSS version 28 through descriptive statistics, frequencies and percentages. Analyses were descriptive only; no inferential testing, factor analysis or regression was undertaken, and the three studies are compared as a descriptive synthesis rather than pooled into a single dataset. Results: Findings across all study groups demonstrated high levels of awareness regarding edible insects, with awareness reported by 85% of participants in Study 1 and 100% in Study 2, and 98% of staff members acknowleded the ecological importance of insects. Mopane worms (Gonimbrasia belina), termites and grasshoppers emerged as the most recognised and frequently consumed edible insect species. Consumption prevalence was notably high, reported at 91% in Study 1 and 69.2% in Study 2 and 66.3% among staff in Study 3. General attitudes towards entomophagy were largely favourable, with 41% of students expressing excitement about edible insect consumption and 91.1% of staff supporting the commercialisation of edible insects. Key barriers influencing consumption included religious restrictions (25.1%, reported in Study 2 only; participants with religious dietary prohibitions were excluded at sampling in Studies 1 and 3, limiting cross-study comparability of this barrier), cultural taboos (3%), inadequate market availability and limited awareness regarding nutritional benefits. Staff members further demonstrated positive environmental and sustainability perceptions, with 84.1% recognising edible insects as environmentally beneficial and viable future food sources. Conclusions: Across three independent cross-sectional studies conducted at the University of Venda, broadly similar patterns of awareness, attitudes, perceptions and edible insect consumption were observed. Although the studies differed in sampling and measurement, they consistently suggest that edible insects remain culturally accepted among many students and staff. Nevertheless, challenges relating to nutritional literacy, market accessibility and policy integration continue to limit broader adoption. Strengthening nutrition education initiatives and incorporating edible insects into institutional food systems may enhance the contribution of edible insects towards food security, sustainable protein provision and nutrition sustainability within Limpopo Province and beyond.
