Abstract

To determine relation of functional diversity with species richness, we investigated insect diversity of a pecan stand in Jiande, the sweep sampling and the route survey method were applied. Then, based on nine biological traits including ecological characters, four indexes of species diversity （Richness，Shannon，Simpson and Evenness） and six indexes of functional diversity （Functional richness, Functional attribute diversity，Modified FAD，Functional dendrogram，Convex hull hyper-volume，Functional specialization）were obtained. Also, two dimensions of insect diversity （species diversity and functional diversity） and the relationship between both dimensions were studied using the MSR index. 589 insect specimens collected in the survey, which were identified 160 species belonging to 11 orders. Results of the analysis by DPS 14.10，FDiversity and Excel 2003 revealed that: 1） advantage of orders were Homoptera, Coleoptera, and Lepidoptera; and the greatest species diversity and functional diversity were in an insect sub-community. 2） Also, the selected functional traits easily distinguished the functional diversity among the community. 3） FAD, MFAD, and FD indexes increased with increasing species diversity. belonging to MSR index （Monotonically increasing with Species Richness）, in this case community will be more stable and the pests in the pecan stand will easily be suppressed in low density. Also, FAD and MFAD were similar. Thus, functional diversity in the pecan stand could be used as guidance for pest control.［Ch, 6 tab. 30 ref.］
