JALDO, Héctor E.; WILLINK, Eduardo  and  LIEDO, Pablo. Demographic analysis of mass-reared Anastrepha fraterculus (Diptera: Tephritidae) in Tucumán, Argentina. Rev. ind. agríc. Tucumán [online]. 2007, vol.84, n.1, pp.15-20. ISSN 1851-3018.

The life cycle of a lab-adapted mass reared strain of Anastrepha fraterculus at 24°C constant temperature was 41 days, including the preoviposition period. Mortality rates of 8%, 22%, 22%, 5%, and 43% were recorded for eggs, larvae, pupae, adults (preoviposition stage) and adults (reproductive stage), respectively. The intrinsic rate of increase was 0.065, the net fecundity rate was 120.4, and the gross fecundity rate was 328.4. In a stable population, 22% would be eggs, 53% larvae, 18% pupae, 4% preoviposition adults, and 3% reproductive adults.

Keywords : South American fruit fly; Mortality; Fertility.
