Abstract Soil microbiotic crusts are widespread in arid and semiarid regions, they are one of the major components of desert ecosystems, and their importance has been demonstrated by numerous researches. However, little research has been carried out on the relation between soil microbiotic crusts and the diversity of insect species. In this study, with the psammophilous Caragana Korshinskii-Artemisia ordosica communities on semifixed dunes and fixed dunes in Shapotou region at the southeastern fringe of the Tengger Desert as the observation sample plots, the survey quadrats were arranged in the vegetation community areas with different types and coverages of soil microbiotic crusts. The insects were surveyed in 100 m×100 m quadrats and caught by sampling frame and net-trap methods. The insects number was recorded and samples were collected for indoor identification. The surveyed results show that as compared to the uncovered vegetation area, the existence of soil microbiotic crusts in the Tengger Desert region significantly increases the diversity and abundance of insect species, especially the diversity and abundance in the quadrats mainly covered by moss and lichen crusts are significantly higher than those in the quadrats mainly covered by cyanobacteria and algal crusts. The contribution of soil microbiotic crusts to the diversity of insect species may be attributed to the facts that it stabilizes soil surface, improves soil environmental and there by provides suitable habitats and some food sources for the insects.
