Notes on the Codling moth

The Codling Moth (Carpocapsa pomonella) is attracting so much attention at present that I hope I may be excused for making some remarks upon the subject.
This insect belongs to that family of the Lepidoptera called Tortricidae (in French, "Tordeuses"), on account of the general habit of their larvae of "twisting" or rolling up the leaves of plants of their abode, usually those leaves enclosing a young shoot or bud. They then devour such leaves, shoots or buds, to the great detriment of the plant attacked. A few take up their abode in the interior or fruits, especially the apple, pear, and plum.
