THE PLUM CURCULIO. 
In Table XXXII are brought together from the preceding tables 
the totals showing the time spent in the fruit at the several localities. 
The horizontal bars mark weekly periods from time of deposition 
of eggs, beginning with the second week. The percentage of the 
total number of larvae emerging weekly is also shown. From the 
Illinois, District of Columbia, and Georgia records it will be noted 
that there was a considerable emergence of larvae in the localities 
in question during the second week. This was highest in the District 
of Columbia, where almost 30 per cent of the total larvae emerged 
during the second week. In Georgia, 18.7 per cent of the larvae 
came out during the second week in 1906, and during 1910 the pro- 
portion was 20.77 per cent. In all localities a notable majority of 
the larvae emerged during the third week, and with the exception of 
the Georgia material during 1910, emergence from the fruit was 
practically over by the close of the fourth week from deposition of eggs.
