It will be seen from figure 8 that emergence began on May 30, and 

 reached its maximum on June 11, after which time the moths de- 

 creased in numbere, ceasing to appear altogether after June 23. 

 It would probably be safe to say that the first-brood larvae were 

 entering fi'uit by June 1, or very soon thereafter. 



FIRST-BROOD MOTHS. 



The emergence records of 148 moths given in Table X were obtained 

 from the material collected in the orchard at Hagerstown and repre-

 in the field. The 148 moths accounted for in this table comprise all 

 that transformed during that season of the 1,706 larvae reared, a fact
