Many field crops may suffer for a season or two. Fig. 64. Jarring peach tree for curculio. from wireworms or white grubs if planted in fields, as pastures or old meadows, that have been in sod for several years and are the favorite breed- ing grounds of these pests. But thorough cultiva- tion of such crops will soon discourage the insects. Clean culture, or the destroying of weeds and clearing away of rubbish, will often help in the warfare against insect pests. Many insects find favorable hibernating quarters in rubbish, old stone walls, near-by clumps of bushes or forest lands. One fruit-grower has largely eliminated the plum curculio from his peach orchard by planting it away from such favorable hibernating quarters. The removal or burial of old cabbage stumps, old squash or cucumber vines, and other garden refuse, so as to leave the ground clean in the fall, will help much in controlling garden insects, like the cabbage, radish- and onion-maggots, cutworms, and other serious pests. Sometimes an attractive plant is used early in the .season as a decoy, to be de- stroyed when it has served its purpose and become well infested with the pest. Then the main crop to be protected is planted later and often escapes serious infestation. A strip of mustard or early cabbages may be sown early in spring to attract the hibernated harlequin-bugs, which can then be killed with kerosene before the main crop of cab- bage is put out. A strip of wheat sown in August will often attract a large proportion of the autumn brood of the hessian fly. This infested strip can then be plowed under in September, or just before the whole field is prepared for the main crop, which should be delayed in planting as long as local conditions will permit.
