The present study evaluated the effect of soil inhabiting suppressive microbial populations on survival of Fruit Fly (Anastrepha fraterculus Wied.). A suppressive effect was observed with one of the soil samples used, although from the data it is not possible to conclusively assert that the effect is due to biological causes (suppressive microbial communities). Additionally, the effect of post-harvest treatments on the quality of mango fruits affected with Colletotrichum gloeosporioides (Penz.) Sacc. and Anastrepha fraterculus Wied. was evaluated. The effectiveness close to 100% of thermal treatment by immersion in water at 46°C for 60 minutes was confirmed for the control of A. fraterculus. The same treatment slowed down the loss of quality of the harvested fruits due to C. gloeosporioides. Finally, it was determined that the modified atmosphere packing (MAP) treatment with a 200-µm thickness plastic has potential to control the same disease without negatively affecting the quality of the fruits.
