. Annual report of the New York State College of Agriculture at Cornell University and the Agricultural Experiment Station. New York State College of Agriculture; Cornell University. Agricultural Experiment Station; Agriculture -- New York (State). 192 Bulletin 396 Northern Spy apples punctured b}' the feeding bugs between June 12 and June 14 were photographed when examined on July 8, at which time the characteristic splitting of the skin was well developed about the wounds (fig. 25). The condition of the larger apple shown in figure 25 is almost an exact duplicate of the condition on July 8 of the Northern Spy apple shown in figure 26. The mature apple (fig. 26) shows how the scars have run together and healed to such an extent that no de- pressions have been formed. The Baldwin apples punctured between June 10 and June 18 were examined on July 3, at which time they showed the characteristic splitting of the skin about each of the punctures. This condition is well illustrated in figure 28. It is at this stage that the scars very much resemble certain developments of apple scab (fig. 29). In figure 30 are shown two mature Rhode Island Greening apples with the rus- set scars produced from the type of in- juries illustrated in figure 28. These look very different from the Rhode Island Fig. 28. BALDWIN APPLES (JULY 3), SHOWING HOW THE SPLITS Gfeefiins SiGxAes, il- AND SCARS SPREAD FROM THE REDBUG PUNCTURES ° ^^ lustrated in figure 31, which show the scars resulting from the early-feeding punctures of the bugs. Very soon after the adult bugs emerge, or by June 25 to 27, the apples have attained such a size and the growth is so gradual that the punctures made by the bugs do not split and enlarge as was the case earlier. In figures 32 and 33 is shown the effect of late feeding of adult bugs, which may result in mere dimples or in tiny russet spots, depending much on the variety affected. The spots in the left-hand apple in figure 33 resemble very closely the dimples caus
