The time of appearance of larvae and their relative abundance in the respective localities have been graphically shown by curves in figures 18 and 19. It will be noted here that there is practically no differ- ence in the time of appearance of the first larva? in the five localities; nor is there any difference in the time of appearance of the earliest second-brood larvae, so far as this could be determined. In account- ing for this uniformity in time of maturity of larvae it should be remembered that the seasonal conditions during 1911 were quite.

The spring opened up suddenly and uniformly over the entire fruit belt, and the prevailing high temperature must have started the development of the insects more or less at the same time in the different sections. During 1910, it will be recalled that in these localities a slight difference was observed in the time and rate of appearance of the first brood of larvae and practically no difference in the time of appearance of the second brood of larvae. We may deduce from these observations that the seasonal development may in years become more uniform in the different sections of the fruit belt than is generally the rule, and that these differences are more in evidence during the early spring than during the rest of the season, while at midsummer conditions are more or less uniform for the whole Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original United States.
