LIFE HISTORY AND CONTROL OF HOP FLEA-BEETLE. 51 greatly simplified the operation and has made banding much more l)ractical. Since the beetles can not crawl over the bands the vines are per- fectly protected. In case the beetles are numerous when the vines are first trained, the tanglefoot may be applied at that time, or if the beetles are not troublesome during the first generation it may be ai)plied after the vines are stripped so it will be ready for the second brood. In that case, however, the poles must be banded as well as the vines, for the beetles have a habit of climbing the poles and crawd- ing along the wires, where they do much damage to the hop cones. Effect u-pon the beetles.—The tangle- foot bands not only keep the beetles off of the vines but a large number of them are caught in it. In places Avhere the beetles were very thick, hundreds of them became entangled in it and in some instances so many got caught that they formed a bridge over which the others crawled. Beside being killed by coming in contact with the tanglefoot, many are starved to death by being kept away from the hop-leaves. This was espe- cially true in the yards that were kept well cultivated and all suckers cut awa3^ If the weeds are not allowed to grow in the yards and the vines and poles are well banded, most of the beetles will either be caught in the bands or starved to death, the remainder going into win- ter quarters in such poor condition that there will be few beetles the next spring. AppUcatiori.—It is necessary to get the tanglefoot well into the spaces be- tween the two vines, the simplest way to accomplish this being to apply it with the hands. A section about G inches long should be coated with the tanglefoot, care being taken that no parts are missed and that no leaves are left to form a bridge across it. A strip around each pole about 3 feet from the gTound should be trimmed off with a
