this study was to investigate the potential diets of high nutritional valuewithin local plant organic matter (MOVL) and test their effects on the growth performance ofthe different larval stages of H. illucens fly. For that, five types of MOVL-based diets wereformulated, added to the two-day-old larvae and replicated five times. As results, diet blend ofbrewery malt and Mix (soya bean, oil cakes, groundnut) registered the best growthperformances of fly larvae (weight gain, specific growth rate and daily growth) followed by diet formulation of brewery malt mixed with yeast. These two diets also enabled the larvae tocomplete their development stage in only 8 days of follow-up and achieved a balanced sexratio compared to the other diets at the end of the experiment. These results showed that MOVL-based diets could optimize rearing and mass production of H. illucens larvae for theirsubsequent use in animal feed.Keywords: Black soldier fly, plant organic matter, growth, emergence, sex ratio compared to the other diets at the end of the experiment.
