Abstract：We had investigated the biodiversity of Heteroptera insects in Yaoluoping Nature Reserve, Anhui province, China from 2006 to 2007 The numbers of species and individuals were sampled in different habitats, time and altitudes. The species were listed, and Margalof index, Simpson index, ShannonWiener index, Pielou index, and Whittaker index were used to analyze the true bugs community. A total of 102 species of Heteroptera belonging to 77 genus, 13 families are reported in which 33 pecies are reported in Anhui Province for the first time. The results of the fauna indicate that Oriental species were dominant ones, Palaearctic species second, while the common species of Oriental and Palaearctic regions are least. The result of the community’sαdiversity shows that the order of community diversity from highest to lowest are: the habitats range from broadleaf bush, broadleaf forest, grassland forest, bamboo forest to farmlands; time range from May, July, June, April, September and August; altitude belts range from 1 100, 800, 700, 600, 900,1 000,1 200, 500 to above 1 300 m.The correlation analysis on the indices of diversity, the indices of Pielou and the indices of Margalof show that the relevance among the ShannonWiener indices, the Simpson indices and the Margalof indices is remarkable, but the ShannonWiener indices and the evenness are not correlative in different habitats, time and altitudes. The results of the community’s β diversity shows that the habitat is the remarkable factor on component of Heteroptera community.
