Abstract: Starting from the key point of insect degradation plastics, this paper focuses on the review of insect species and the mechanism of eating degradation plastics. It is found that there are 14 types of insects eating plastic in the world, and the degradation of plastics by some insects is due to their intestinal microorganisms. At present, the research methods of insect degradation plastics include product analysis, stable isotope tracing, bacterial culture and metagenomics. Some problems in this field and future research directions are put forward. It is hoped that this paper can provide an overview of insects based strategies on degradation of environmental plastic pollution.
