Superworms on all diets were able to complete their life cycle to pupae and imago, although superworms reared on polystyrene had minimal weight gains, resulting in lower pupation rates compared to bran reared worms.


In this study, we assessed changes in the gut microbiome of superworms ( Zophobas morio) reared on bran, polystyrene or under starvation conditions over a 3 weeks period. Polystyrene, including extruded polystyrene (also known as styrofoam), is among the most commonly produced plastics worldwide and is recalcitrant to microbial degradation. Plastics are inexpensive and widely used organic polymers, but their high durability hinders biodegradation.
