Thus the first larvse of the second brood appeared August 31. Similarly, the first-brood and second-brood larvae in the Lake Shore and New Richmond experiments have been determined, with due consideration given to the seasonal conditions of each locality. The results from three band experiments may be appreciated by an examination of the curves in figure 10. A difference in the time and rate of maturity of larvae will be noted in considering the height of the curves representing the first brood. In the Lake Shore orchard.
