Summary The experiment was carried out in order to analyze the results of interspecific competition which were mentioned in the previous reports ( Sasaba 1964, 1965). The following definite tendencies were obtained and an account was given with regard to the process of competition. (1) T. minutum had a higher reproductive rate than T. japonicum at a lower density of the parent wasps. (2) The parasitic efficiency of T. minutum was high as compared with T. japonicum . (3) T. japonicum was consistently superior to T. minutum in the interspecific competition at larval stage.
