Abstract: In order to know the intraspecific and interspecific struggle relation of termites which damaged the landscaping in Sichuan,5 species and 38 nests of termites were collected,parts of the termites from each population were dyed,marked,and fed,then the marked termites and the normal termites from different population were put in one petri dish to observe and record the battle of termites. The results showed that there were no intraspecific and interspecific struggle among Reticulitermes chinensis, Reticulitermes labralis and Reticulitermes flaviceps,there were interspecific struggle, but no intraspecific struggle in Reticulitermes aculabialis; and there were intra-and-interspecific struggle in Coptotermes formosanus. So the struggle among termites depended on the species and the population of termites.
