In southernMexico, four native and one introduced species of Opiinae (Braconidae) attack larvae ofAnastrepha spp. fruit ßies. There is a substantial overlap in thehosts of the parasitoids, and every species has been collected from fruit ßies attacked by at least one or two other species. The ovipositors of these braconids have a broad interspeciÞc range of lengths, some are less than the length...

Four new species of opiine Braconidae are described from Mexico. These are Diachasmimorpha martinalujai Wharton reared from Rhagoletis infesting fruits of Crataegus spp., Diachasmimorpha norrbomi Wharton reared from Euphranta mexicana infesting fruits of Ribes pringlei, Eurytenes (Stigmatopoea) norrbomi Wharton reared from Trypeta concolor mining leaves of Barkleyanthus salicifolia and Eurytene...

opiine braconid parasitoids of tephritid pests have augmentative biological control potential, but there are no synthetic attractants to monitor their survival and dispersal following release. adults feed on fruit juices and these could be sources of attractive compounds. While orange juice (Citrus sinensis l.) is nutritious, guava juice (Psidium guajava l.) is toxic. the behavioral responses t...
