Bean. Bean-weevil or Bean-bug (Bruchus obtectus). - Closely resembles the pea-weevil, which see for description and remedies. Holding over the seed will be of no value with this insect. Seed-corn Maggot. (Pegomya fusciceps). - A maggot attacking germinating seeds and roots of young plants.

Treatment. - Avoid stable manure ; practice crop rotation. In the garden use sand moistened with kerosene around the plants to keep the flies from laying the eggs. Birch. Bronze Birch-borer (Agrilus anxius). — A slender, creamy white grub, three-fourths inch in length when full grown, that burrows under the bark of the white birch, ultimately killing the tree. The eggs are laid during May and June by a slender, olive-bronze beetle about one-half inch in length.

Treatment. - After a tree has become thoroughly infested, nothing can be done to save it. As the first indication of the presence of the borer is usually a dying of the topmost branches, such trees should be carefully examined, and if infested should be cut down and burned before May 1, to prevent a spread of the trouble to other trees. Blackberry. Cane-borer. - See under Raspberry, p. 330. Root Gall-fly. - See under Raspberry. Snowy Cricket. - See under Raspberry. Cabbage. Cabbage-worm or Cabbage-butterfly (Pontia rapae). -The green caterpillars hatch from eggs laid by the common white butterfly. There are several broods every season.

Treatment. - If plants are not heading, spray with kerosene emulsion or with paris green to which the sticker has been added. If heading, apply hellebore. Flea-beetle. — See Flea-beetle, p. 303.

Common Cabbage-looper (Autographa brassicae).— A pale green caterpillar, striped with lighter lines. Feeds on the leaves. Treatment. — Arsenicals applied to lower surface of leaves. Cabbage Aphis (Aphis brassicae). — These small, mealy plant-lice are especially troublesome during cool, dry seasons, when their natural enemies are less active.

Treatment. - Before the plants begin to head, spray with kerosene emulsion diluted with 6 parts of water or whale-oil soap, 1 pound in 6 gallons of water, or use one of the concentrated tobacco extracts. Destroy all cabbage stalks and other cruciferous plants in the fall. Dip infested plants in soap solution before planting. Harlequin Cabbage-bug (Murgantia histrionica). — Bug about a half-inch long, gaudily colored with orange dots and stripes over a blue-black ground, feeding upon cabbage ; two to six broods.

Treatment.— Hand-picking. Place blocks about the patch, and the bugs will collect under them. In the fall make small piles of the rubbish in the patch, and burn them at the approach of winter. Practice clean culture. Destroy all cabbage stalks and other cruciferous plants in fall. Early in the spring plant a trap crop of mustard, radish, rape, or kale. When the overwintering bugs congregate on these plants, destroy them with pure kerosene or by hand. Maggot (Pegomya brassicae). — A minute white maggot, the larva of a small fly, eating into the crown and roots of young cabbage, cauliflower, radish, and turnip plants.

Treatment. — Carbolic acid emulsion diluted with 30 parts of water applied the day following the transplanting of the cabbage plants, and repeated once a week for several applications. Remove a little earth from about the plants, and spray on the emulsion forcibly. It has also been found practicable to protect the plants by the use of tightly fitting cards cut from tarred paper.

In seed beds protect the plants by surrounding the bed with boards one foot wide placed on edge, across which a tight cover of cheese-cloth is stretched. Carrot. Parsley-worm. — See under Parsley, p. 324.

Carrot-beetle (Ligyrus gibbosus). — A reddish brown beetle one-half inch or more long, which attacks the young plants. The larva lives in the ground, where it feeds on humus.

Preventive. — Crop rotation and other remedies for white grub, which see under Corn, p. 314.

Cauliflower. Cauliflower or Cabbage-worm. — See under Cabbage.
