DESTRUCTIVE INSECTS. 193 r^^T?r in general to most localities in the United States north of Washington, D. C. In Canada the moths do not begin to fly until about a month later, while in the South they appear a month or more earlier, so that the dates in the above sketch will not apply to these regions. The insect is open to successful attack only in its larva or borer stage, and in its pupa stage; the pupae are reached only by searching for the co- coons and destroying them. After four years of careful experimenting with most of the meth- ods recommended to control this pest, we are led to the following con- clusions : The " digging out" method is the only thoroughly successful and safe way of killing the peach-tree borer. This method is expen- sive in time and labor, but our experience leads us to believe that any other equally as suc- cessful method will cost just as much. To make it a success the " dig- ging out" should be thoroughly done, not only on every tree in the orchard, but also on all " old relics" of peach-trees in the immediate neighborhood. A half-dozen such " old relics" left untreated near by will serve thoroughly to restock an orchard with borers every year, so that the " dig- ging out" method, although practised each year, will never reduce the numbers of the borers below the danger limit. 13. m-^^^>^.^ i\ Fig. 2S9.âWork of a Single Borer in a Peach- tree, natural size, zv b.
