Abstract: Comparisons among different calculation methods were conducted in order to analyze the species associations of fig wasps associated with Ficus racemosa in Xishuangbanna,SW China.The results indicated that interspecific associations were highly significant(P <0.01).Pollinator(Ceratosolen fusciceps)had the highest significant associations with other species, negatively with Platyneura testacea and P.mayri,while positive with P.agraensis .There were highly significant negative associations among 3 species within genus Platyneura,whereas,a highly significant positive association occurred between the 2 species of genus Apocrypta .The interspecific association relationship was not clear yet for pollinator and Apocrypta species.Semi-matrices diagrams and constellation diagrams were applied to show species associations of fig wasps.The causes and evolutionary effects of species association status of 6 fig wasp species were also discussed.
