12 DECIDUOUS FRUIT INSECTS AND INSECTICIDES. 
SECOND-BROOD LARVZ. 
Period of hatching—According to records of oviposition,: the first 
larvee of the second brood would have hatched June 18. They began 
hatching in numbers in the cages June 21. Reared larvee entering 
fruit as late as August 3 were undoubtedly of the second brood, as 
they pupated on reaching full growth. Some of the brood probably 
hatched later still, making a total period of entrance to the fruit of 
perhaps 55 days for such larvee of this brood as pupated. 
Maturing of larve.—The band record (p. 24) indicates that second- 
brood larve began to leave the fruit by July 15. The first of the 
reared larve left July 13, and were from eggs laid 4 days later than 
the earliest, so mature second-brood larve may have appeared by 
July 10. The band records of both 1907 (p. 23) and 1908 (p. 24) 
indicate that the last of the second brood left the fruit early in Sep- 
tember. 
Period in fruit.—A large number of second-brood larve hatching 
during the night of June 22 were transferred to bagged fruit June 25. 
Seventeen of these reached maturity after an average time in the fruit 
of 24.6 days, the time ranging from 21 to 31 days. The individual 
records are given in Table XI.

Several of the same lot of larve were put on picked fruit and kept 
in jars out of doors. Most of these spun cocoons in the fruit, and had 
pupated before the fact was noticed. Three of them, however, left 
the fruit after periods of 21 and 22 days. The fact that these larve 
had been kept in jars instead of on bagged fruit seems to have 
hastened development, as the average time from oviposition to emer- 
gence of adult of 11 individuals of this lot was 42.3 days, as against 
49.5 days for the 17 individuals on bagged fruit. Nine second-brood 
larve hatching July 28 to August 3 were reared in picked fruit in jars, 
and reached maturity in from 16 to 20 days, the average being 17.7 
days. Individual records of this lot are given in Table XII.
