The curve of figure 16 represents the total emergence of moths and is based upon the records of Table L. It will be noted that there existed a striking similarity in the rate of emergence and that the time of emergence. Fig. 1G.—Emergence curve of moths of the summer brood in 1911, at Douglas, Mich. (Original.) was practically the same for the different band records. Tliis may be due to the peculiar climatic conditions of 1911, when the spring opened up uniformly over the entire fruit belt—a rather unusual occurrence. It may also be that during the middle of the summer the seasonal conditions became equalized over the different sections, and produced a corresponding equalizing tendency upon the develop- ment of the codling moth. The emergence records for the summer moths are remarkable both in respect to time and r;ite of appearance of the moths. The earliest moths issued July 8, which emergence was 21 days earlier then that of the more normal season of 1910. During the early part of the emergence period, from July 10 to July 14, moths appeared in abundance. During the later half of July, however, they were less.
