Abstract
Parasitoids of the Mediterranean fruit fly, Ceratitis capitata (Wiedemann), and the oriental fruit fly, Dacus dorsalis Hendel, were monitored on ripe loquat and wind-fallen peach fruits in the Kula area of Maui, Hawaii, from 1979 through 1985. The percentage of parasitization ranged from 31 to 52% annually. Biosteres arisanus (Sonan), an egg and larva parasitoid, accounted for 74% of the total parasitization, but on several occasions, the larva parasitoids, Biosteres longicaudatus Ashmead and Biosteres tryoni (Cameron), each exceeded 30% parasitism. In most cases, the parasitoid male/female sex ratio was 1:1. The results suggest that opiine parasitoids are important factors in regulating fruit fly populations in Kula, Maui.
