The Page orchard, like the Darnall orchard, was found in 1914 to be heavily infested with roundheaded apple-tree borers. The trees within the orchard and within a strip 300 feet in width sur- rounding the orchard were cleaned of borers. The orchard contained 464 trees from which were removed 290 borers, 254 of which were from eggs of the current season.

The trees within the orchard and within a strip 300 feet in width sur- rounding the orchard were cleaned of borers. The orchard contained 464 trees from which were removed 290 borers, 254 of which were from eggs of the current season. This orchard was surrounded en- tirely by pasture lands over which grew scattering seedling apple, crab apple, and hawthorn trees in which many borers were develop- ing. The second annual examination,, which was made in August, 1915, showed that 55 eggs had been laid in the orchard trees. One. Fig. 3, A.—Saperda Candida.

In another part of the orchard a group of 7 trees contained 42 young borers. This group of infested trees was near the outer border of the orchard, and 275 feet distant another fresh female exit hole was found in a seedling apple growing in the pasture field, the author of which had been overlooked the previous year. It seemed probable that this beetle had flown to the orchard and that the two females overlooked the previous year were respon- sible for all the eggs which, w
