In 1910, band-record experiments were placed in three separate 

 orchards, located several miles apart, for the purpose of establishing 

 better average results and determining as far as possible the extent 

 of existing variation in the time of development of the codling moth 

 in the selected localities. These were chosen in regard to their rela- 

 tive proximity to Lake Michigan, one near the lake, one 2 miles cast, 

 and the other 7 miles east of the lake. The influence of the lake upon 

 the temperature over the fruit belt of the western part of Michigan 

 is well known by the local fruit growers and horticulturists and is 

 strikingly shown by the difference in the period of blossoming of 

 apples. This period is much earlier in orchards situated inland and 

 later in orchards near the lake. It should therefore be expected that 

 the codling moth is influenced in its development to a similar extent.
