The use of these combined technologies in tropical fruits does not present satisfactory results yet, most of the time because of the fruits injury by chilling. This injury could be intensified under atmospheric control conditions. There are evidences that the controlled atmosphere has fungistatic effect. Therefore, the objective of this work was verifying, in vitro, the influence of controlled atmosphere and temperature on the two pathogenic fungi from papaya fruit: Colletotrichum gloeosporioides and Cladosporium cladosporioides. These fungi had been storage under two temperatures, atmospheres and period of incubation patterns (10ºC and 25ºC; ambient and controlled - 3% O2 and 6% CO2; 7 or 14 days. After this period of storage, the contaminated plates had been incubated at 25ºC under environment atmosphere for seven days more. It was verified a small growth of Colletotrichum gloeosporioides under refrigeration, also after additional period at 25ºC. At 25º C, the growth of this fungus was also reduced when stored under controlled atmosphere. On the other hand, it was not verified significant inhibitor effect of the controlled atmosphere at 10ºC on the growth of C. gloeosporioides. The growth of Cladosporium cladosporioides was reduced at 10ºC in both periods of storage. After seven days at 25ºC, C. cladosporioides showed a small growth in the plates that had been stored for 14 days, because the influence of the refrigeration and the controlled atmosphere. Finally, the controlled atmosphere reduced the growth of the C. cladosporioides at 25ºC. This effect was not observed at 10ºC for C. gloeosporioides.
