Hosts were multiparasitized at 2nd instar. One hundred hosts (n = 100) were used for each experiment, except for the competition with M. pulchricornis (n = 50). Two types of statistical tests are performed: (1) two-tailed binomial test by F-distribution approximation for the superiority of C. floridanum (male or female) against each competitor, where a indicates significant at p = 0.00000 and (2) Fisher's exact probability test for the effects of C. floridanum (male or female) on the success of each competitor, where b indicates significant at p = 0.00000.
