. The American farmer. A hand-book of agriculture for the farm and garden ... Agriculture. G68 farmer's hand-book. that is, she pierces the roll, lays an egg in the opening-, and pushes it in with her rostrum in such a manner that it remains on the inner surface of the leaf. When she has thus introduced five or six eggs, between the different folds, she rolls the remaining part of the leaf entirely together, so that it is impossible to. discover, from the outward appearance, in what manner the eggs were deposited. This beetle also finds the leaves of the pear-tree suit- able for its purpose, rolling up the leaves of the leaf-buds. In a few days the eggs are hatched in the rolls, and a whitish small worm comes out of each egg, with black oblique stripes over the back, and a reddish head. In four or five weeks it is fully grown. In the mean time, the petiole and the roll have become so dry that they are easily torn off by a moderately high wind, and fall to the earth. If this does not take place till the worm is fully grown, it leaves the partly-consumed roll, buries itself in the earth, and appears again in spring as a weevil. This beetle, therefore, is the real weevil of the vine, defoliating it, and preventing the grapes from ripening. As it is toler- ably large, it may easily be perceived, and may consequently be destroyed, particularly as it allows itself to be taken without flying away. When it is numerous in orchards, it should be taken off, and the leaf-rolls pulled off, and burnt or crushed. Vine Scale Insect. — This insect forms a longish, marbled-brown scale. In old age the scale becomes blackish-brown, hemispherical and wrinkled. The eggs, which are laid under the body of the female, are covered with long white wool. They are found on vines, particularly in gardens. Theii destruction is best effected by dry-brushing in autumn or spring Fig. Please note that these images are extracted from scanned page images that may have been digitally enhanced fo
