THE CODLING MOTH IN THE OZARKS. Tf 
when a large number of moths were caged on the same date, eggs were 
obtained on the third day. A record of first-brood moths confined in 
a cage is given in Table IX.

In 1907 no first-brood moths were obtained until June 25. In 1906 
Mr. Moulton records the issuing of a moth on June 19 from apples 
sent from Bentonville, Ark. 
LENGTH OF LIFE CYCLE OF FIRST GENERATION. 
The interval between the emergence of the first adult of the win- 
tering brood and the earliest first-brood moth was 69 days. Starting 
with a spring moth emerging after the weather became warm, the 
life cycle would be much shorter. A moth emerging May 5 might 
lay eggs May 10. Eggs laid on the latter date required 74 days to 
hatch. This, together with 24 days in the fruit and 18 days in the 
cocoon, gives a total of about 54 days as an average time for the latter 
half of the first generation. 
THE SECOND GENERATION. 
SECOND-BROOD EGGS. 
The earliest of the first brood of moths began depositing eggs on 
the night of June 13. In 1907 second-brood eggs were not laid in cages 
until July 5. All eggs of this brood required a nearly uniform period 
of 5 days for incubation. In Table X is given a record of the incuba- 
tion of some of the earlier eggs of this brood.
