Summary

"Researchers compared two wax moth species as plastic-degrading agents, finding that Galleria mellonella degrades a broad range of plastics including LDPE and polystyrene, while Achroia grisella excels specifically at breaking down HDPE, suggesting co-deployment of both species could maximize bioremediation of diverse plastic waste."

Excessive plastic waste pollution is a critical environmental challenge. Traditional plastic waste management methods, such as landfilling, incineration, and recycling, are often inadequate and environmentally harmful. Among environment-friendly bioremediation strategies, the degradative potential of insects, particularly greater wax moth (Galleria mellonella) and the lesser wax moth (Achroia grisella) larvae are promising. This review provides a comparative assessment of plastic degradation capabilities in G. mellonella and A.grisella, aiming to refine bioremediation strategies. A systematic search of PubMed yielded eightrelevant studies published between 2015 and 2024. Analysis revealed distinct degradative profiles foreach species; G. mellonella exhibited broad-spectrum activity, effectively degrading diverse plastics likelow-density polyethylene (LDPE) and polystyrene, as evidenced by substantial mass loss and physicaldeterioration; conversely, A. grisella demonstrated exceptional efficiency in high-density polyethylene(HDPE) degradation with rapid breakdown initiation, but showed lower efficacy with LDPE. Thesefindings suggest G. mellonella’s suitability for managing a wider range of plastic waste, while A. grisella offers a targeted solution for HDPE. A potential synergy through co-deployment of these species couldmaximize the degradation of diverse plastic pollutants.
