from hibernation in the spring and lays masses of orange eggs on the under side of the leaves. The larvae are known as "slugs" and "soft-shells" and cause most of the injury to the vines. Spray with Paris green, 2 lb. in 100 gal. of water, or arsenite of soda combined with bordeaux mixture. It may sometimes be necessary to use a greater strength of the poison, particularly on the older "slugs."
The small black flea-beetles riddle the leaves with holes and cause the foliage to die. Bordeaux mixture as applied for potato blight protects the plants by making them repellent to the beetles.
