10 DECIDUOUS FRUIT INSECTS AND INSECTICIDES. 
FIRST-BROOD PUP. 
First-brood larve began to pupate May 27, just a week after the 
last stragglers of the wintering larve under observation had pupated. 
Thus first-brood pup appeared before the last of the spring brood 
had given out moths, the extent of the overlap being 12 days. 
Of 42 first-brood pupex observed, the average duration of the stage 
was 10.7 days, ranging from 9 to 13 days. The total period from 
the time the larva left the fruit until the adult issued averaged 17.8 
days, with a range of from 13 to 21 days. As before suggested, larvee 
not confined in vials would probably pupate sooner, thus shortening 
the “cocoon stage.’ Individual records of first-brood pupe are 
shown in Table VIII.

FIRST-BROOD MOTHS. 
The earliest first-brood moth emerged June 8, on which date the 
last belated moth of the spring brood also issued. Sixteen of the 
earliest moths, caged June 8-15, showed an average life of 6.2 days. 
Oviposition began 5 days after the first moth was caged. In 1907,
