Mortality of the Mexican Fruit Fly from Carbon Dioxide Generated in Buried Mangos and Oranges1

Abstract
Infested oranges buried 8 days under 25–30 cm of soil produced concentrations of 34% CO2 in the air in the burial pits and 85% mortality of the Mexican fruit fly, Anastrepha ludens (Loew); infested mangos handled in the same way produced concentrations of 60% CO2 and 97% mortality. In fruits buried under 10 to 25 cm of soil and left undisturbed for longer periods, the mortality in oranges was 99.7 to 100% and in mangos from 98.7 to 99.7%.
