摘要： Cadmium (Cd) is a common environmental heavy metal pollutant known for its toxic effects on various plants and animals. Cd contamination also poses a threat to Pardosa pseudoannulata, a predator in rice paddies. Results indicate that Cd pollution significantly reduced the levels of Metallothionein, phenoloxidase, and Ca2 +. Furthermore, through metabolomics and 16S rDNA sequencing, alterations in the gut microbiota and immune-related metabolites of P. pseudoannulata were identified. The abundance of harmful bacteria such as Staphylococcus increased significantly, while levels of l-Tyrosine, glutathione disulfide, l-Dopa, among others, decreased markedly. Pearson correlation analysis revealed significant associations between various gut microbes and immune-related metabolites, suggesting that Cd may alter the immune system of P. pseudoannulata by modulating its gut microbiota.
