Abstract
Two types of egg-collection devices for rearing Ceratitis capitata (Wiedemann) were compared for effects on egg production by adults and on egg hatch. Significantly higher efficiency was obtained from females in cages with perforated bottles than in cages with screen as oviposition sites. Consequently, a bottle oviposition cage was modified for large-scale egg production by incorporating a new egg collection method that precludes the escape of flies during egg harvest. The modified cage was equal to or better than the standard plywood cage used for the past 10 years in Hawaii. Specifications were described for a cage and operations system capable of providing 1 × 109 eggs per week.
