MORTALITY OF APPLE MAGGOT IN FRUIT IN STORAGE 3 



EQUALIZATION OF FRUIT AND AIR TEMPERATURES 



It is well known that the time required to lower the initial tempera- 

 ture of the fruit to the point where it is nearly as low as that of the air 

 in the refrigeration room is a variable. Lloyd and Decker, 3 among

others, have shown this to be influenced by such factors as the velocity 

 of air movement in the chamber, the type of fruit container, the loca- 

 tion of any given fruit in the container, and the presence or absence 

 of paper as lining or compartments in the container or as wrapping for
