Many of our orchardists upon find- ing sick and dying trees with the shot hole borer working in them have attribut- ed the cause to the beetles. By visiting many of these places and explaining to the orchardist the true con- ditions, we have convinced them that the trees were suffering from some fungus disease or improper soil condition. The beetles may help to kill the trees and in some cases might cause the death of trees which would have recovered from the disease had the beetles not been pres- ent. In the case of young trees, only one or two years old, this could readily hap- pen, as the burrows extend almost en- tirely around the trees and close to the inner bark. (For example see Pig. 2.). Piff. 2. The Shot Hole Borer. Burrow in yoimg: cherry tree and adults in hibernation In the summer, after the beetles have completed the burrows, such trees can easily be broken off at the point of in- jury. Life History The winter is spent in the adult stage. Both males and females hibernate in the burrows from July and August until the following spring. They emerge during the last of March and first of April and migrate to sick and dying trees, where the burrows of that season are to be made. The entrance hole is usually made about a bud scar or in some roughened place. The beetles have no trouble in picking out the sick trees. The Adnlt The adult bores directly through the bark and into the wood tissue for a quar- ter of an inch or more and then begins the construction of branch burrows ex- tending at right angles to the main bur- row and with the grain of the wood. These channels are all ab
