Apple. Aphids Or Plant-Lice

There are three species which commonly attack the opening buds and leaves of apple, - the leaf aphis (Aphis pomi), rosy aphis (Aphis sorbi) and bud aphis (Siphocoryne avenae).


These small, soft-bodied insects may be controlled by thorough spraying with "Black Leaf 40 ' tobacco extract, three-fourths of a pint, in one-hundred gallons of water, adding four pounds of soap. Make the application before the leaves curl. Apple-Curculio (Anthonomus quadrigibbus). - A soft, white grub, about 1/2 inch long, living in the fruit.


Clean cultivation. Rake the small apples that drop early out into the sun where they will dry up.

Catalogue of Insects, continued.

Apple Flea-Beetle (Graptodera Foliacea)

Brassy, green beetle, 1/5 inch or less long, feeding upon leaves.


Arsenicals. Lime-sulfur or bordeaux mixture as a repellent.

Apple Leaf-Hopper (Empoasca Mali)

A slender pale yellowish green bug; the nymphs are pale greenish and usually found on the under side of the leaves. The winter eggs are laid in blisters under the bark of the smaller branches; summer eggs, m the leaf veins and petioles. Four generations annually. The insect feeds by extracting the juices from the leaves, causing them to turn pale and curl. It is most injurious to nursery stock.


The young nymphs may be killed by spraying with "Black Leaf 40" tobacco extract, three-fourths of a pint in one hundred gallons of water, adding three to four pounds of soap. Nurserymen often catch the adults by the use of sticky shields.

Apple Leaf-Roller (Archips Argyrospila)

A green caterpillar with a black head, 1 inch or less in length when mature, attacks the opening buds rolling and Webbing together the leaves, flowers and young fruit into a nest. Holes are eaten in the young apples, deforming them. Eggs are laid in June in small, flat masses on the bark and are covered with a smooth varnish-like coating. They do not hatch till the following spring.
