In this study, the biodegradation of low-density polyethylene (LDPE) by Galleria mellonella larvae was evaluated under controlled thermal conditions, using a quantitative experimental design with 160 larvae distributed in a completely randomized design with AxB factorial arrangement. The treatments included two temperature levels (26.3°C and 20.5°C) and dietary combinations of LDPE alone and LDPE with beeswax, evaluating the influence of these variables on the weight loss of the larvae and the degradation of the LDPE area. . Larvae exposed to a temperature of 26.3°C demonstrated an average weight loss of 0.02667 grams and consumed an average of 1.26 cm² of LDPE. In contrast, larvae kept at 20.5°C lost an average of 0.01681 grams and consumed only 0.24 cm² of LDPE. These data indicate that higher temperature facilitates more intense metabolic activity, resulting in significantly greater biodegradation of the plastic. Furthermore, the addition of beeswax as part of the diet led to an increase in biodegradation efficiency. Larvae fed the mixture of LDPE and beeswax at 26.3°C consumed an average of 1.48 cm² of plastic, while those on a similar diet but at 20.5°C consumed only 0.10 cm². These results underline the relevance of thermal and dietary conditions in the optimization of biodegradation processes using living organisms as degradative agents.
