It is often practicable to hand - pick or dig out insect pests. This is largely prac- ticed in coun- tries where cheap labor is available. No cheaper and ef- fective method has yet been found for com- bating borers and many pests (a s cutworms and white grubs) working in gardens and on other small areas. Children have done very effective work in collecting eggs of tent-caterpillars and tussock- moths on shade trees. A box-like covering of wire- screen or mosquito - netting is often placed over hills of squashes, melons and cucumbers to protect them from the ravages of the striped beetle and stink-bug. Seed-beds of cabbages, radish beds and various choice or rare plants can be thus protected from insects at slight expense. Bushels of young grasshoppers and swarms of small leaf-hoppers are often collected on the western prairies by drawing large iron pans smeared with tar or containing ker- osene, and called ' hopper-dozers.' (Fig. 59.) Thous- ands of grape leaf-hoppers can be collected on sticky shields held near while the vines are jarred. Fig. 61. Canker-wonn moths stopped by sticky band in their pi ogress up a tree. FiE. 62. Ridge formed by Marcy implement for protection agamst chinch-bugs. Post-holes are dug beside the ridge about fifty feet apart. This barrier is smooth and compact, and very little affected by the rain. The line of coal-tar along the top has been successful in all weather conditions. 'Kansas Experiment Stati
