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.
