Alongside traditional waste management strategies, recent studies have highlighted the potential role of insects in the biodegradation and recycling of organic wastes. One of the most widely recognized candidate species for waste recycling is the housefly, Musca domestica Linnaeus, 1758 (Dip: Muscidae). Due to its high nutritional value, housefly larvae can also be used in poultry and fish feeding as an edible insect. The current study aimed to find the optimal substrate for rearing and compare the effects of five types of waste substrates on developmental time, as well as the weight of larvae and pupae, the sex ratio and adult longevity of housefly under controlled laboratory conditions (25 ± 2°C, 50 ± 10% R.H., and 12:12 L:D photoperiod). The wastes used included brewery waste, slaughterhouse waste, bean canning factory waste, kitchen waste, and wheat bran as a control. The results demonstrated a significant difference in larval duration, larval and pupal weight and adult longevity. Significant differences were found in larval duration, larval and pupal weights, and adult lifespan, whereas pupal period and sex ratio were not significantly affected. The shortest development time and highest biomass were observed in the canned bean waste treatment. Adults reared on canned bean and kitchen waste exhibited the longest lifespans, while the shortest was on slaughterhouse waste. Given the absence of significant differences in all parameters between the control (wheat bran) and brewery waste, it can be concluded that, instead of wheat bran, which is often expensive, brewery waste could be used cost-effectively.
