Structure and biodiversity of insect community on syconia fruits of Ficus racemosa in tropical rainforest of Xishuangbanna, China

Abstract

Abstract: Ficus racemosa is a keystone plant in tropical rainforest of Xishuangbanna, Yunnan.The structure, dynamic and biodiversity of insect community on its syconia fruits were investigated in different plots located in Menglun nature reserve, ravine rainforest in the botanical garden, and secondary forest by Luosuo River.The results showed that the total number of collected insects were 184 264, belonging to 5 order, 19 families, 36 genera, and 51 species.Hymenoptera was the most dominant group, accounted for 37.3 % of the total collected species.The pollinator of Ceratosolen fusciceps had huge individual quantities among Hymenoptera, and its successful pollination influenced the stability and development of F.racemosa population.In addition, the proportion of Lepidopter inspects was 31.4%, and the other 31.3% species belonged to Coleoptera, Homopter and Diptera.Through calculating diversity index, evenness index and richness of three plots, it showed that these three indexes were the highest in Menglun nature reserve, secondary in ravine rainforest, and low species diversity and richness in secondary forest by Luosuo River.The experimental results reported here showed that the insect species decreased, the individual number of common species increased, and special species reduced.

Key words: Tropical rainforest, Ficus racemosa fruits, Insects community, Diversity
