"Evaluation of Expanded Polystyrene and Low-Density Polyethylene Consumption by King Worm Larvae (Zophobas Morio)"
AI summary Read the abstract
This study evaluated the ability of Zophobas morio larvae (king worms) to consume expanded polystyrene (EPS) and low-density polyethylene (LDPE), finding that larvae fed oats combined with EPS showed the highest consumption efficiency, averaging 534 mg over the experimental period. Results suggest these larvae are more effective at degrading EPS than LDPE.
To analyze the process of evolution of the consumption of expanded polystyrene (EPS) and low-density polyethylene (LDPE) by larvae with an average of 5 cm of Zophobas morio, the design of completely randomized blocks with 8 treatments and 3 replications, measurement of weight and consumption time, in different types of substrates, compared with a control of diet alone during the degradation process of (EPS) and (LDPE). According to Tukey’s test at 99% probability of consumption efficiency, more effective were those containing (EPS) and better treatment of oat substrate, being (oats + EPS) the most effective with an average of 534.33mg. In general, in terms of the mean by time, the highest value was observed at 24 days with an average of 333.98mg. However, in the highlighted treatments (EPS) it was higher than 50% according to the consumption efficiency percentage formula.

Researchers conducted a laboratory experiment to determine the optimal feed composition of polystyrene foam (PSP styrofoam) combined with concentrate for Tenebrio molitor larvae, measuring survivorship, body length growth, biomass, and waste degradation rate across seven treatments with three replicates. Results showed that lower PSP ratios combined with higher concentrate proportions improved all four parameters, with 1 kg of larvae degrading 0.25 kg of styrofoam waste over 60 days.

Biodegradation of Pristine and Post-Consumer Extruded Expanded Polystyrene Packaging by Zophobas atratus Larvae: Influence of the Larval Stage and Physiological Response
AI summary Read the abstract
Researchers evaluated Zophobas atratus larvae (superworm beetles) as biodegraders of expanded polystyrene packaging, finding that larger larvae consumed more material while smaller larvae showed greater enzymatic activity, with both life stages reducing molecular weight and causing oxidative chemical changes. The study demonstrates that Z. atratus can biodegrade both pristine and post-consumer polystyrene, with degradation efficiency depending on larval developmental stage and substrate type.
