The mortality of three life cycle stages of red flour beetle (Tribolium castaneum (Herbst)) was assessed in sealed 500 g packs of golden-coloured, sultana raisins, with or without the addition of a commercial O2 absorber, Ageless®. Assessments were undertaken at 30°C for 9 days, or 22.5°C for 20 days, or 15°C for 45 days. Allfruitsamples treated with O2 absorbers produced 100% mortality, with no occurrence of a second-generation population, when incubated post-treatment at 27°C for 60 days.Fruitstored in an hermetically sealed bag produced 100% adult mortality at 22.5°C and 30°C but eggs and pupae survived; at 15°C mortality was not significantly different to the control culture. The effect of a low O2 atmosphere generated by Ageless® onfruitcolour was assessed using the same temperature regimes over a 28, or 56, or 84-day storage period.Fruitcolour changes were measured using the CIE tristimulus L*, a*, b* measuring system. Low storage temperature (15°C) and low O2 atmosphere both maintainedfruitcolour during the experimental storage regimes. There were significant negative effects onfruitcolour at the higher temperature (30°C) and longer storage period without amodified atmosphere.
