Abstract
In Hawaii in 1967 and 1968, as many sterile adult Mediterranean fruit flies, Ceratitis capitata (Wiedemann), and melon flies, Dacus cucurbitae Coquillett, exited within 30 minutes from Kraft paper bags that contained X-shaped cardboard inserts and sugar cubes and were loaded with 3000 pupae, as exited from the more costly compartmented and ventilated cardboard boxes (with sugar-water as food) used previously. The bags were dropped 2.5 meters and opened immediately. A smaller percentage of the packaged insects exited bags containing excelsior or bags with the X-shaped inserts with a solution of water and sugar provided as food. A higher percentage of flies of either species exited the containers loaded with 3000 pupae than from those containers with 5000 pupae. Melon flies left the containers twice as quickly as the Mediterranean fruit flies. Also, sunny and/or calm days permitted greater egress of both species than cloudy and/or windy days.
