“Many grasshoppers will be seen strike the sheet-iron back, drop into the pans and immediately jump out again. Those farmers who observed the experiments were at first of the opinion that the locusts that jumped out had jumped away ‘to live another day.’ The writer asked those interested to watch the insects and note the actions of grasshoppers that had jumped out. In every case the report was that the insects became sick and soon died. In fact, persons going over fields where a day or so before the hopper dozer had been at work, were impressed with the number of dead grasshoppers on the ground. An examination showed the presence of coal-oil upon the body. This kerosene and water is an external irritant, and my observations have been that the mixture is more effective than the oil alone. “The use of the machine may be best shown by examples. In Ford county, Kansas, a large tract of alfalfa was cut, and the locusts at once began moving into a large field of Kafir corn which had been sown broadcast. The hopper dozer was drawn back and forth across the end of the corn field nearest the alfalfa land until a portion of the field about twenty rods deep had been gone over. Here it was apparent that there were very few grasshoppers; or, in other words, the advance line of the locusts’ march only extended twenty rods into the field. Two days later the same area of ground was covered, but not as many insects were taken. Grasshoppers no longer entered this corn and the hopper dozer was no longer used at this point. “It has been my experience with this machine that after it has passed over vegetation it does not injure the plants, but in some way renders the vegetation distasteful to the grasshoppers, so that they turn their course and seek food elsewhere. I have observed that these native grasshoppers enter a field from one corner or side, and that they are not as a rule scattered over the whole field, but occur in great numbers in patches. This being the case, it is evident that with very little labor with this machine the products of a field can be given full opportunity to mature.” ARMY WORMS In Nebraska the fall army worm has caused considerable damage. It is distinct from the true army worm, having small hairs growing out from small black spots; it has a whitish “Y” shaped mark upon the head. The parent of the worms is a moth of a yellowish, ash-gray color. The female moth deposits her eggs in clusters upon the leaves and stems. With the approach of cold weather the worms pass into the ground and enter the chrysalis stage about one or two inches below the surface. When very numerous the only effective treatment is to disk thoroughly in the spring. BIND WEED
