Two or three applications several days apart will be necessary to get the plants clean; 
avoid shade, dryness and crowding. 
Usually appear quickly in large numbers; quick work is necessary to save the plants. 
Hide in leaf axils; if only a few appear kill with match stick and alcohol. 
Avoid dry atmosphere; apply water with as much force as possible several times a 
week to foliage. 
Use hand picking into can of kerosene and water in connection with spray. 
Dipping is most effective treatment; rinse carefully afterwards. 
Very small; they eat the leaf epidermis leaving the skeleton. 
Avoid any sudden shock, such as a cold draft from a window, etc. 
Before spraying remove and burn all affected leaves or plants carefully.

Spray must reach under side of leaves, especially of melons; several applications three 
or four days apart. 
Late in summer all vines^ should be cut and burned. 
Use BM in connection with LA; tobacco dust as preventive. 
Make a poisoned bran bait by mixing 1 qt. wheat bran, one teaspoon white arsenate, 
one teaspoon cane molasses. 
Especially injurious to seedlings of cabbage, turnip and radish; tobacco dust as 
preventive. 
Especially injurious to eggplant; hand pick as well as spraying. 
Tobacco dust as preventive as soon as plants get above ground; kerosene emulsion for 
young bugs. 
Tobacco dust as preventive as soon as old flies appear; injury is done by the young 
Nymphs. 
Keep vines sprayed after middle of July with BM as preventive. 
For cucumbers, same as above; for potatoes, begin spraying when about six inches high, 
and keep new growth coated. 
Keep covered with BM after the middle of July; on celery late spraying should be 
done with AC, which does not stain the foliage and stalks.

Three times; b B O; a B F; f 14 d. 
Spray thoroughly in late fall or early spring. 
Twice; when leaves appear; b B O. 
Burn nests before caterpillars begin to spread. 
Same as for Codlin-moth. 
In addition to spray use burlap bands on trunk for trap during July. 
Spraying not very effective; jar trees every cool morning and catch beetles on sheet; 
spread beneath for several weeks after B F. 
At first appearance, usually before blossoming, spray at once. If a second brood ap¬ 
pears after fruit forms, use hellebore. 
Be careful to cover under side of foliage. 
Spray during winter or early spring, covering every part of trunk and branches. 
KE, medium strength, applied in May or June, when young scale which appear like 
small, whitish lice, hatch out. 
BM until middle of July; after that, AC. For one or two vines cover each bunch 
when half grown with manila “store” bag. 
Keep fruit thinned so it will not touch. Gather cherries before quite ripe and spread 
out in a cool, airy place. 
In using LS, be sure not to get it too strong. 
Keep plants pruned to open form to allow free circulation of air. 
Keep plants sprayed during first season and until a B second season.
