Fruit-culture. INSECTS INJURIOUS TO APPLES. 131 The Apple-worm, (Carpocapsa pomonana,) attacks the fruit, oy entering at the blossom, and feeding at the core. In some. Fig. 106. years, it has been so common, as seriously to injure the quality of the crop. The best preventive is to allow swine to pick up the wormy fruit as it falls, thus destroying the enclosed insect, and preventing its spread. The above figures, (106,) exhibit the apple-worm in its different stages; a, the larva; b, the same magnified; c, the cocoon ; d, the pupa within the cocoon; e, f, the perfect insects; g, the young larva, just hatched, after having been deposited within the calyx ; h, i, Jc, I, the progressive work of the larva within the apple, till it escapes.* The Wooly Aphis, {Aphis lanigera,) a European insect, falsely termed American blight, is a species of aphis or plant-louse, covered with long, white, cottony hair. In England it has proved very destructive; and on young trees in this country it has done some injury. It is destroyed by whale-oil soap, and by lime-wash. Other species of aphis often infest the 3'oung leaves; they are easily killed by a solution of whale-oil soap, which may be applied by a syringe or by immersing the branches. * The curculio or plum weevil, when very numerous, attacks the apple, and its pe- culiar crescent-shaped incisions may be perceived on the skin of tender varieties. The larva, however, rarely reaches the core. But the apple worm never attacks the plum, which has no permanent calyx for the lodgment of its Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the or
