The integration of the sterile insect technique (SIT) in the management of the South American fruit fly Anastrepha fraterculus (Wiedemann) (Diptera: Tephritidae) is a promising alternative to chemically-based control in those areas where it is sympatric with Ceratitis capitata (Wiedemann) (Diptera: Tephritidae) or other tephritid species for which the SIT is being used. Implementation of the SIT requires the development of a cost effective mass-rearing protocol. In this work, we present demographic and quality control parameters for the A. fraterculus strain reared at the Estacion Experimental Agroindustrial Obispo Colombres, Tucuman, Argentina. Considering the rearing cage as the reproduction unit, we observed that fecundity is optimal during the first 3 weeks after the onset of oviposition. Fertility was constant during this period. During 2003 and 2004, some improvements were made to the existing rearing protocol, which resulted in increased larval viability, pupal weight, and adult emergence. Current weekly egg production is 1 million per week. These eggs are used to maintain the colony and to assess quality parameters. Finally, research needs leading to improved yields and fly quality are discussed.

La implementacion de la TIE requiere del desarrollo de un protocolo de cria masiva que sea costo-efectivo. En este trabajo presentamos parametros demograficos y de control de calidad de la cepa criada en la Estacion Experimental Agroindustrial Obispo Colombres, Tucuman, Argentina. Considerando a la jaula de cria como unidad reproductiva, se observo que la fecundidad es optima durante las tres primeras semanas de iniciada la oviposicion y que la fertilidad se mantiene constante durante ese periodo. Durante 2003-2004 se implementaron mejoras en el protocolo de cria existente lo que resulto en un incremento de la viabilidad larvaria, del peso de pupas y del porcentaje de emergencia de adultos. La produccion actual semanal es de un millon de huevos. Los mismos son utilizados para mantener la colonia y realizar distintos estudios de calidad de esta cepa. Por ultimo, se sugieren necesidades de investigacion para alcanzar mejores rendimientos. (author)
