The data recorded in Table XV only indicate the possibilities in 

 lengthening larval life. Except at temperatures from 58° to 62° F., 

 none of the larvae would have been able to mature had they been 

 kept at the temperatures recorded. The data merely bring out the 

 fact that upon the examination of the host fruits after so many days 

 the larvae recorded were found alive. A very large percentage of the 

 larvae within the same fruits were dead, but this mortality, due to 

 exposure to cold for prolonged periods, is discussed elsewhere.
