Effects of Three Pesticides on the Earthworm Lumbricus terrestris Gut Microbiota.

ABSTRACT: Earthworms play a vital role in the terrestrial ecosystem functioning and maintenance of soil fertility. However, many pesticides, for example, imidacloprid, benomyl, and metribuzin that are world-widely used in agriculture, may be potentially dangerous to earthworms. At the same time, standard tests for pesticides acute and chronic toxicity do not reflect all aspects of their negative impact and might not be enough sensitive for effective assessment. In this paper, we studied the effects of non-lethal concentrations of imidacloprid, benomyl, and metribuzin on the gut bacterial community of Lumbricus terrestris using high-throughput sequencing approach. We found that pesticides reduced the total bacterial diversity in the earthworm's gut even at the recommended application rate. Und
