Objective To analyze the diversity of mosquito species at different elevations in the scenic areas of Mount Tai, Shandong province, and to provide basis for mosquito control in this area. Methods From April to October 2016,adult mosquitoes were collected by mosquito light trap during night,and human landing catch during daytime in three different altitude spots chosen as sampling areas. Catches were identified and analyzed by species and elevations. Results A total of 1 762 mosquitoes were collected, of which 1 096 were captured by light trap that were identified to belong to 9 species in 4 genera. In total, 666 mosquitos were captured by human landing that were identified to belong to 3 species in 3 genera. Among all the mosquitoes collected, 1 153 mosquitoes were from the lower altitude that were identified to belong to 9 species, 530 mosquitos from intermediate altitude that identified belong to 5 species and 79 mosquitos from high altitude that were identified to belong to 5 species. The species of mosquitoes from lower altitude were the most abundant(9 species) but Shannon-Wiener index(0.820), Pielou index(0.820) and the meeting rate of species(0.617) in this area were the lowest. The species of mosquitoes from high altitude were the minimum(5 species) and Shannon-Wiener index (1.315), Pielou index(1.881), the meeting rate of species(0.671) in this area were the highest. Conclusion The mosquito species of scenic spots in Mount Tai is obviously different. The species richness, population density and biomass were higher at lower elevation. But Shannon-Wiener index, Pielou index and the meeting rate of species showed the reverse trend. It is helpful to study the diversity of mosquito communities in the studied area.
