Résumé Des lâchers de la mouche parasite, appelée vulgairement mouche de Cuba, dans les champs de anne, en Floride, ont limité les populations du foreur de la canne. La tachinaire a parasité 20 à 78% des foreurs. En outre, la descendance des parasites a été retrouvée à plus de 3 km des points de lâcher. Les dégâts aux cannes à sucre furent moindres dans les champs où les lâchers ont été effectués que dans les champs voisins.

Abstract Lixophaga diatraeae (Townsend) parasitized 20 to 78% ofDiatraea saccharalis (F) larval populations within 3 weeks after release. The flies (4 to 6 days old) did not migrate from the release area, but the progeny dispersed as much as 3 km into adjacent untreated areas within 5 generations. Progeny dispersal, apparently during the prelarviposition period, resulted in 100% parasitization ofD. saccharalis larvae in some plots. In 2 of the 3 tests, the host population decreased after the releases. Percentage damaged internodes increased with distance from the release site.
