Description:
We have shown in research work also presented in this meeting that insecticidal controlled atmospheres at high temperatures are very efficient in causing in vitro mortality of eggs and third instar larvas, and in vivo mortality of third instar larvas of Anastrepha ludens and A. obliqua. In this work we are reporting on their effect on the quality of mango fruit. Fruit of the cultivar `Manila' were exposed to 0% O2 + 50% CO2 at 40, 42, 43, 44, 45, 46, 47, 48, and 49°C and 50% relative humidity for 160 min, after which they were stored at 10 °C for 20 days and evaluated at different intervals. Fruit exposed at 44°C or more had heat injury, while those exposed at 43°C or less did not show any injury and had similar or better quality than the control. On the basis of our previous results on insect mortality and on the resulted fruit quality reported here (heat injury, color, texture, weight loss), we conclude that 0% O2 + 50% CO2 at 43°C or less for 160 min can be used for the control of A. ludens and A. obliqua in mangoes.
