Background: Insects such as black soldier fly, Hermetia illucens are being considered as a new protein source for animal feed. Integrated development of innovative technologies for insect production using locally available agro-industrial wastes is necessary at present. Objective: To investigate the use of locally available agro-processing wastes namely palm kernel cake, maize bran, sorghum spent grain, soya bean waste and their combinations for maggots production. Method: Randomized complete blocs design with four repetitions was used. Statistical analyses were performed using SPSS Statistics 17.0 software. ANOVA was used to compare different parameters means and significant differences between the various treatments were set at P<0.05. Results: From 10 to 14 days after incubation, the percent length gained by the larvae varied from 15.34 % (palm kernel cake) to 35.2% (maize bran). There were significant differences in total weight and substrate productivity among the treatments. At 14 days after incubation, the average production of black soldier fly larvae from simple substrates varied from 152.25g (sorghum spent grain) to 446.87g (palm kernel cake). Conversion rate of the substrates to dry matter varied from 8.8% (sorghum spent grain) to 27.01% (soya beans waste). Conclusion: It can be concluded that soya bean waste, palm kernel cake and a mixture of the latter and maize bran could be the best substrates for producing H. illucens maggot for small scale producers.
