In regions less moist than in Central New York it is possible that some of the methods, listed above as unsatisfactory, will prove good preventives against this serious pest. Washes should be applied about June 15th in Northern orchards, and must remain in- tact for over two months. The Fruit-tree Bark-beetle or Shot-hole Borer {Scolytus rugulosus).—Th& bark of plum, peach, cherry, and apple-trees may appear thickly " peppered " with holes, as though by fine bird shot (Fig. 261). These are the en- trance and exit holes of a small beetle (Fig. 260 a) whose grubs (Fig. 260 d) excavate narrow galleries in various directions under the bark, and often kill the tree or some of its branches. Usually only sickly or un- thrifty trees are attacked by the insect. It is a very difficult insect to combat. Bad- ly infested trees should be burned at once. Keep the trees in good health and they will. Fig. 261.—Work of the Fruit-tree Bark-beetle in Twig of Apple, natural size. (U. S. Div. of Ento- mology.).
