THE INSECT RECORD FOR I9OI 35 be expected, the comparatively few apples set were badly in- jured by the attacks of the Codling Moth and the Plum CuRCULio, while in some parts of the state, notably Cheshire county, the Apple Maggot or Railroad Worm was extra- ordinarily destructive. For the first two of these pests spray- ing every year with arsenate of lead or other arsenical poison is a good remedial measure, but for the third the only method yet devised is that of keeping the fallen apples cleaned up by means of sheep or hogs. And to be efiective this must be practised by a whole community. The apple trees also suffered an unusual attack from a pest which I have not before known to be destructive in this state —the Apple Leaf-Hopper. This is a small greenish-white " fly," which ap- peared early in the spring upon the under surface of the leaves, sucking out the sap and causing the upper surface to be spot- ted with white. The drain upon the vitality of the trees must have been quite serious, and is likely to show at least in the smaller size of the fruit the coming sea- son. When adult these leaf-hoppers can fly freely. Their appearance in the stage preceding the adult is shown in the two small creatures on the leaf below the caterpillar in Fig. 4. In the southern part of the state Cankerworms have con- tinued to do serious injury to many orchards. I noticed in those which came under my observation that as usual the birds were doing what they could to check the outbreak. Robins, bluebirds, cedar-birds and many others fed freely upon the pests. A discussion of remedies for these cater- pillars has been given in Bulletin '$>^ of this Fig. 4 Young Apple Leaf-Hoppers on leaf below the Caterpillar.
