Hibernating Bud Borers were found at x, x, x, often at the base of a leaf stem. (Delaware Experiment Station.) The bud borer has a wide distribution. It seems to be held in check, however, by a natural enemy in the form of a small fly. Apple Twi^ Borer Amphicerus hicaudatus, Say Attacks apples, pears, cherries, and other trees, and bores into the twig just above a bud for food and shelter. The beetle which does the damage is about one-third of an inch long, cylindrical in form, brownish above and black under- neath. Remedies The remedy that is recommended is to look for the infested twigs, cut them off and burn them. See also page 505. Branch and Twig Borer Polycaon confertus Lee. H. F. Wilson Although apparently never doing any amount of damage this insect is often found attacking the stems and branches of pome fruits and even grapes. Nothing is known of its life history in Oregon, but in California the larvae work in live oak trees and it is very likely that they do the same here. The adult beetles start in to burrow above the buds and excavate a shallow burrow downwards, rarely deeper than the length of the body. This burrow is about one-fourth inch in diameter and why it is made is not known unless it is for the purpose of feeding, as they apparently never deposit eggs in them. They have never been abundant enough to cause any great alarm, but the bur- rows offer excellent opportunity for the entrance of fungi and decay organisms. There is no known method of preven- tion..
