Picking the fruit would of course put an end to the band record. It will be noticed in the curve (fig. 2) that the second brood is many times larger than the first. But the third brood, instead of showing a further increase, is scarcely larger than the first. This is not to be taken as evidence of only a partial brood, but is due to the fact that the fruit was harvested before the bulk of the third brood had Fig. 2.—Curve showing record of larvse ami pupae of the codling moth taken from bands in 1907. The 1908 band record (Table XXXI and fig. 3) was influenced by the very smal' size of the apple crop in that year.
