58 REPORT ON THE FIG MOTH IN SMYRNA. 
The fellowing table gives the rate of rise in temperature of the 
interior of the three figs and the resultant average rise. The average 
for periods of over 74 minutes is taken from two figs only:

Since the rise of temperature was variable in the three figs, to reach 
more nearly the exact rate of rise an average was taken of recorded 
temperatures from all. Thus, for the interior temperature to reach 
90° C. required in the first fig 7 minutes, in the second 5 minutes, 
and in the third 64 minutes. For the interior of the average fig to 
reach 90°, therefore, would require about 6 minutes. 
That 100° C. is necessary to cause immediate death to larve does 
not mean that figs must be boiled 10 minutes to kill the larve in 
them. Larve will as surely succumb to a temperature of 90° C., if 
sustained for a longer period, as to 100° C. in a short period. The 
accumulative heat at lower temperatures of the fig up to the point 
where the “ required ” temperature is reached has a decided devitaliz- 
ing effect upon the larva. In boiling figs, larve will perish some 
time before an interior temperature of 100° in the figs is reached. 
Therefore it must be learned by further experiment what tempera- 
tures below 100° C., sustained for what lengths of time, will prove
