Abstract:

Objective To study the community structure and diversity of mites breeding in tobacco storage in Anhui province, China. Methods Samples (tobacco leaves and tobacco dust on the ground) were obtained from four different habitats (simple storage, open storage, tenemental storage, and alcoholizing storage) of tobacco storage, and mites were collected, isolated, identified, counted, and analyzed. Results Twenty-three species of mites belonging to 16 genera and 5 families were collected. The species number, species richness, and species diversity of mites were the highest in simple storage, followed by open storage, tenemental storage, and alcoholizing storage. The species evenness of mite community was the highest in simple storage (J'= 0.959), while the species domination of mite community was the highest in alcoholizing storage (D=0.150). The Jaccard similarity index between the mite communities in open storage and alcoholizing storage was the lowest (Q=0.238). Conclusion The community structure and diversity of mites breeding in tobacco storage in Anhui province are closely related to the habitat conditions, and there are relatively few mites breeding in alcoholizing storage.
