The variability of antioxidant capacity of 14 strains of the edible oyster mushroom Pleurotus spp. was determined, and the effect of selected mushroom supplements on the longevity of the Mexican fruit fly, Anastrepha ludens, was evaluated. The antioxidant capacity of the fruiting bodies was determined by three different methods, measuring the free radical scavenging activity of methanolic extracts, the OH radical scavenging capacity, and the total phenol content. The inhibition percentage of the DPPH radical varied between 32.6 and 85.7 % and total phenols varied between 30.6 and 143.3 mg/g. The strains with the highest (Pleurotus djamor ECS-0142) and lowest (Pleurotus ostreatus ECS-1123) antioxidant capacity were selected to study their effect on the survival, life expectancy, and mortality of the Mexican fruit fly A. ludens. The results demonstrated differing responses between male and female flies. High concentrations of mushrooms (5 and 20 %) in the diet resulted in a decrease in life expectancy. However, flies on the diet with 1 % P. djamor ECS-0142 showed slightly but significantly greater survival than those on the control diet. The possible adverse effect of protein content in mushroom extracts is discussed.
