CODLING MOTH IN NORTHWESTERN PENNSYLVANIA. 103 
In 1908 the band-record experiments were carried out at Westfield, 
N. Y., in an unsprayed orchard consisting of large apple trees belong- 
ing to Mr. George Walker and kindly placed at the disposal of the 
Bureau of Entomology. The bands were examined once a week, and 
Fia. 26.—Band-record curve of 1907, at North East, Pa. (Original.) 
the larve were counted and removed to the laboratory for further 
observations. As is evident from figure 27, the bands were placed on 
the trees about one week too late, so that no record was obtained of 
the earliest maturing larve. The two broods are here clearly dis-

tinguishable, overlapping but slightly at the end of August. The 
great drop in the number of larve in early October (fig. 27) was due 
to cold weather. In Table XX XIX is given the full record of the band 
collections for 1908, with a summary in Table XL.
