Scurfy Scale (Chionaspis Furfurus)

This whitish, pear-shaped scale, about 1/8 inch in length, often incrusts the bark, giving it a scurfy appearance. It hibernates as purplish eggs under the old scales.

Treatment

Spray as recommended for oyster-shell scale.

Tent-Caterpillars (Malacosoma Americana And M. Disstria)

Larvae nearly 2 inches long, spotted and striped with yellow, white, and black; feeding upon the leaves. They congregate in tents or in clusters on the bark at night and in cool weather, and forage out upon the branches during the day.

Treatment

Arsenicals, as for codlin-moth. Burn out nests with torch, or cut them out and crush the larvae. Pick off egg masses from twigs during winter and spring.

Tussock-Moth (Hemerocampa Leucostigma)

A handsome, redheaded, yellow and black tufted caterpillar, about an inch long, which devours the leaves and sometimes' eats into the fruit.

Remedial

Collect the frothy egg-masses in fall and winter and band the trees to prevent a reinfestation by migrating caterpillars. Spray with arsenicals as for codlin-moth, taking care to cover the under side of the leaves.

Twig-Borer (Schistoceros Hamatus)

Beetle, 3/8inch long, cylindrical and dark brown, boring into twigs of apple, pear, and other trees. The beetle enters just above a bud.

Treatment

Burn the twigs. The early stages are passed in dying wood, such as prunings, diseased canes, and in upturned roots. Burn such rubbish, and thus destroy their breeding-places. This is also a grape pest.

Twig-Girdler (Oncideres Cingulatus)

Small branches are often girdled by a handsome ash-sprinkled reddish brown beetle, about 1/2 inch in length. The girdled twigs soon fall and the grubs develop in the fallen branches.

Treatment

Collect and burn all fallen branches.

Woolly Aphis (Schizoneura Lanigera)

Small reddish brown plant-lice covered with a conspicuous mass of white, waxy fibers, found on the branches, sprouts, trunks and roots.

Treatment

For the form above ground drench the infested parts with 15 per cent kerosene emulsion; for the underground form remove the earth beneath the tree to a depth of 3 inches, and apply 10 per cent kerosene emulsion liberally, and replace the earth. In the case of nursery stock the emulsion may be applied in a shallow furrow close to the row. Do not set infested trees.

Yellow-Necked Apple Caterpillars (Datana Ministra)

Apple branches are often defoliated in late summer by colonies of black- and yellow-striped caterpillars about 2 inches in length when mature.

Treatment

Same as for Red-humped Caterpillar, which see.
