[Sawfly diversity along an altitude gradient in Mao'er Mountain of Guangxi].
The sawfly diversity was investigated at seven sampling sites along an altitude gradient in the Mao'er Mountain National Nature Reserve of Guangxi in spring. A total of 803 sawfly specimen belonging to 121 species, 58 genera and 3 families were collected, and the dominant and widespread species were Claremontia sinobirmana Malaise and Nesoselandria southa Wei. The maximum values of the species richness index, Simpson index and Shannon-Wiener index of sawfly communities occurred at the altitude of 1000-1500 m, being 12.293, 0.971 and 3.830, respectively, while the dominance index was the highest at high altitude. The sawfly species at the seven sites were divided into two groups, i.e., high altitude group ( > 2000 m) and other altitude group ( <2000 m). Precipitation and vegetation type were the main factors affecting the sawfly diversity.
