We released 85,000 mass-reared Fopius arisanus (Hymenoptera: Braconidae) at a central location in a papaya orchard at Kalapana, Hawaii Island. We monitored the released parasitoids at eight directions and five distances from the release site using two METHODS: yellow sticky spheres and "sentinel fruits" containing oriental fruit fly eggs. With strong northeastern winds at the time of release, initial dispersal was greatest to the south at 15 meters, but movement to 30-60 meters was greatest to the southeast and southwest, and to a lesser degree to the east and west. Little movement was observed at greater distances (120 and 240 meters). Results will be helpful for designing future augmentative parasitoid releases for the suppression of tephritid fruit flies.
