CODLINC! MOTH IN CENTRAL APPALACHIAN REGION. 



15 



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 numbers, ceasing to appear altogether after June 23. 

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

 entering fruit 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- 

 sent fairly well the occurrence of the summer or first brood of moths 

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

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

Fig. 8. — Diagram to illustrate emergence of spring-brood moths of the codling moth at Smithsburg, 

 Md., and first-brood moths at Hagerstown, Md., in 1912. 



winch probably accounts for the relatively small number of second- 

 brood larvse that appeared under the bands later in the summer (see 



fig. 9).
