It manifests itself by weakening the growth and causing the bark of the canes to become marked with many white or grayish, flattened or depressed spots, bordered by a ring of pur- ple; some of these spots may be one-third of an inch in diameter. This disease seldom does serious injury to any but cap varieties of the raspberry, and it is only occasionally noticed to any extent in this state, and then not as being very hurtful. In some of the eastern states it is so abundant as to almost prohibit the growing of cap varieties. The treatment for this disease consists in burning all the in- fected canes and in applying Bordeaux mixture to the new growth occasionally during the growing season, commencing early. Insects.—The rasberry is seriously injured by but few insects. The most common are the following: Raspberry Flat-headed Borer (Agrilus ruficolUs ) Fig. 14. The perfect form of this insect is a beetle which lays its eggs in the growing canes some time during the summer. Where the eggs are laid peculiar gall-like swellings may occur {Fig. 15), having many rough slits in them; but this is not always the case, for sometimes canes may be killed by the insect and no swell- ings at all appear on the canes. The eggs hatch into little yellow- ish-white larvae, having a flattened body, brown jaws, and a tail fur- nished with two dark-brown horns. One swelling may contain many larvae. When full-grown the larvae is from one-half to three- fourths of an inch long, and by burrowing in the wood frequently girdles the canes. The perfect beetles emerge about the time the plants are in full blossom. They have a brilliant copper-colored
