comment:
The solitary endoparasite, Cotesia rubecula, was superior to the gregarious endoparasite, Cotesia glomeratus, in tests of intrinsic competition for their host Artogeia rapae. When an egg of C. rubecula was oviposited in the host prior to those of C. glomeratus, C. rubecula always won the ensuing competition. When an egg of C. rubecula was laid in the same host within 48 h after oviposition by C. glomeratus, C. rubecula was successful in more than 90% of the interactions. Even when the egg of C. rubecula was oviposited in the same host 72 to 96 h after oviposition by C. glomeratus, C. rubecula won the competition approximately 33% of the time. The implications of intrinsic competition are discussed in relation to the establishment of C. rubecula in an ecosystem containing A. rapae and C. glomeratus. none
