Plastic-eating insect discovered in Kenya

There’s been an exciting new discovery in the fight against plastic pollution: mealworm larvae that are capable of consuming polystyrene. They join the ranks of a small group of insects that have been found to be capable of breaking the polluting plastic down, though this is the first time that an insect species native to Africa has been found to do this.

The abundance of bacteria indicates that they play a crucial role in breaking down the plastic. This may mean that mealworms may not naturally have the ability to eat plastic. Instead, when they start eating plastic, the bacteria in their guts might change to help break it down. Thus, the microbes in the mealworms’ stomachs can adjust to unusual diets, like plastic.

Certain insect species, such as yellow mealworms (Tenebrio molitor) and superworms (Zophobas morio), have already demonstrated the ability to consume plastics. They’re able to break down materials like polystyrene with the help of bacteria in their gut. This regional focus is important because the insects and environmental conditions in Africa may differ from those in other parts of the world, potentially offering new insights and practical solutions for plastic pollution in African settings.
