Economic entomology for the farmer and the fruit grower, and for use as a text-book in agricultural schools and colleges; . \;^ Cranberr>-fruit worm, Mineola vaccinii.— a, cranberry on which (b, c) the eggs are laid ; , . r ^< '^rva; e,/, pupa and its tip ; g, cocoon ; It, berries there is no way of moth, getting at them, and, practi- cally, the only method of reducing their numbers is to pick the berries as early as may be, being careful to get in all that are infested. By sorting promptly these can be destroyed before the larvae leave them, lessening greatly the number of moths for the following year. The insect is much more troublesome in New England than in New Jersey or in the northwestern marshes. Nearly allied, but with totally different habits, is the Mineola indighiel/a, or "rascal apple-leaf crumpler," so called from its habit of making irregular, crumpled cases on the apple leaves upon which the insect feeds. It is rather easily reached, where it becomes troublesome, by the arsenical sprays, and in orchards where spraying is generally practised it is incidentally destroyed. Many other of these little species are found on our cultivated crops, but, as a rule, in such small numbers as to be hardly no- ticeable, and only occasionally a species becomes locally injurious. One of the largest of our Eastern species is the Melitara pro- denialis, which feeds inside the leaves of the prickly pear or common cactus of the sandy regions south of Long Island, while its near ally, M. dentata, is found in an allied cactus in Kansas
