American Blight, the apple-bark plant-louse, or woolly aphid, which forms a cottony film on neglected apple-trees. It is said to have been imported into Britain from America in 1787, but this is doubtful. Cleaning the trees, choking the parasites with anything oily or sticky, treatment with tobacco-water and other washes, are among the suggested remedies. See APHIDES; also see Injurious Insects (1885), by E. A. Ormerod.
