Sad and Leaf-feeding Insects. —The buds and leaves of horticultural crops often swarm with legions of biting and sucking Insects. A mere enumeration of the dif- ferent kinds of these pests would weary the reader. Some Insects, like the rose chafer, work on several dif- ferent kinds of plants, while many others attack only one or two kinds. In apple orchards, the opening buds are seized upon by the hungry bud-moth and case-bearing caterpillars, by the newly-hatched canker-worms, and by tent-caterpillars, whose tents or " signboards " are fa- miliar objects in many orchards. These pests continue their destructive work on the leaves. The pear slug often needs to be checked in its work of skeletonizing the leaves of the pear and cherry. The pear psylla, one of the jumping plant-lice, is a very serious menace to pear-growing in many localities; the fruit is either dwarfed or drops from badly infested trees, and some- times so many little pumps sucking out its life finally cause the death of the tree. The little blue grape-vine flea-beetle often literally nips the prospective crop of fruit in the bud, or the rose-chafer may swarm over the vines and eat the foliage or blossoms.
