Abstract: Objective To investigate the community structure and species diversity of ticks parasitized on the domestic animals(goats,cattle and buffaloes) in Qiongzhong area of Hainan provice,and analyze the relationship of them and the diseases.Methods Ticks specimens were collected from the body surface of every domestic animals during April to October 1997 and 1998.Every tick was finally identified into species by microscope.All the ticks parasitized on the domestic animals were defined as one community unit.Richness(S),Shannon-Wiener's,diversity index(H'),evenness(J') and dominance index(C') were adopted to measure the community structure of ticks.Results 2614 ticks were collected from the body surface of 35 domestic animals(20 goates,10 cattle and 5 buffaloes).All the ticks were identified as 4 species which belonged to 4 genera of 4 families.Of 4 ticks species,2 main ticks species(Rhipicephalus sanguineus and Boophihus microplus) accounted for 51.57% and 45.22% of the total specimens,respectively,which were the dominant species.The C',H' and J' of goats were all higher than that of cattle and buffaloes.Conclusion There were 4 species of ticks that parasitized on domestic animals in Qiongzhong area of Hainan provice.R.sanguineus and B.microplus were dominant species.This investigation showed that the community structure of ticks species parasitized on goats were the most abundant.
