Exotic or Native? Interspecific Competition in the Parasitization of the Fruit Fly Ceratitis cosyra

摘要: Fopius arisanus Sonan and caudatus Szepligeti (Hymenoptera: Braconidae) are two solitary endoparasitoids of tephritid fruit flies that parasitize eggs infesting the same fruits. We studied intraspecific competition between these parasitoids species in mango fly Ceratitis cosyra (Walker) (Diptera: Tephritidae). Based on previous documentation equal chance survival F. ceratititvorus Wharton while co-parasitizing (Bokonon-Ganta et al., 2005), we hypothesized would not find a superior competitor parasitoids.
