The adultmoth usually emerges in the fall, gener-ally beginning about the middle or latterpart of October; although a considerablenumber come out of the earth in thewinter during warm weather and in thespring. The moths of both sexes lackthe abdominal spines characteristic ofthe spring canker-worm. Remedies.—The two species of canker-worm are so much alike in their habitsthat the same remedies will do for both. The wingless female moths should beprevented from climbing the trees to fig. 3. canker-worm Moth 150 REPORT OF STATE BOARD OF HORTICULTURE. deposit their eggs in the fall. This can be done by placing a wirenetting trap, as shown in Fig. 3. First place around the tree a pieceof cotton batting, and then a strip of wire netting of No. 16 mesh,six or eight inches wide. Tie at top with cord or wire. See that thenetting does not touch the tree at bottom. The insects will collect underit and go up as far as they can, being attracted by the light through thenetting, and there perish. After the female has ceased crawling orhatching, the traps should be removed and scalded, as eggs depositedon them will hatch and the minute larvae will get through the trunks of the trees below the trap should also be scrubbed or coatedwith a thick whitewash. Remedy against the Larva.—Spray the infested trees with one poundof Paris green to 200 gallons of cold water. To prevent
