Lai Conglong (Sichuan Agricultural University) Qiu Xianmeng Luo Xiufen Fan Wenan (Research and Conservation Center For the Giant Panda, Wolong Nature Reserve, Sichuan Province. China)  
From Nov.1985 to Dec.1988,We analyzed feces from 2680 defecation sites in 28 counties(includ- ing nine nature reserves)in Sichuan Province,and Baishuijiang Nature Reserve (Wen county)in Gansu Province.Ten grams were taken from each samples and examined by the method of sedimentation and flotation.Ascaris schroederi eggs were discovered in 1505 of the 2680 samples,corresponding to an in- fection rates of 56.15%.Corresponding frequencies and infection rates for species were:Toxascaris sele- nactis eggs 121 (4.51%);Ogmocotyle so.eggs 13 (0.48%);Strongylata eggs3 (0.11%);lunsworm larvas 1 (0.04% ).Thus Ascaris schroederi was the dominant internal parasite in the samples collected. The infection rates in different areas,elevations and age groups were not significantly different.
