Elm Leaf-Beetle (Galerucella Luteola)

A small beetle, imported from Europe, which causes great devastation in some of the eastern states by eating the green matter from elm leaves, causing the tree to appear as if scorched.

Remedy

Arsenate of lead, six pounds to one hundred gallons, just as the eggs are hatching.

Elm Saw-Fly Leaf-Miner (Kaliosysphinga Ulmi)

A greenish white larva feeding between the two layers of the leaf, causing large blotches; when abundant, the leaf dies and falls. They sometimes kill the trees in two or three years.

Treatment

While the blotches are small, spray with Black Leaf 40," tobacco extract, one gallon in 800 gallons of water, adding four pounds of whale-oil soap to each hundred gallons.

Leopard Moth (Zeuzera Pyrina)

White to pinkish caterpillars boring at first in the smaller twigs and branches. Later the nearly mature caterpillars attack the larger branches and trunk, doing very serious injury. The white moths, beautifully marked with black and blue, have a wing expanse of about 2 1/3 inches.

Treatment

Cut off and destroy all infested branches. The spread of the pest is very slow if the branches of the trees do not interlace.

Willow-Worm

See Salix.

Violet. Aphis

Fumigation when grown under glass.

Gall-Fly (Contarinia Violicola)

The adult is a minute mosquito-like fly. The whitish or yellowish maggot feeds in folds of the opening leaves, which become deformed, turn brown, and die.

Treatment

Fumigation is practically of no value. Thorough hand-picking as soon as any sign of injury is noticed. Do not let the pest become established in the house.

Red-Spider (Tetranychus Bimaculatus)

Minute mites which cause the leaves to turn paler and become yellowish.
