Show Fall Army Worm Advancing North On Annual Raid ino tail, army worm, wnlch is marching northward from Toxus and Louisiana. Is leaving a wake of stripped strip-ped cornstalks and bare sorghum fields. Before wlntor sets in and effectually ef-fectually destroys the pest for the 3'ear, the fall army worm may be expected ex-pected in all the northern states. It is on of tho most destructive of posts the farmer has to contend with. The fall army worm, when vory young, is nearly black It grows rap-Idly, rap-Idly, ultimately obtaining a length of about 1' 1-2 inches. At this Btago the body is striped on a ground varying in color from a pale yellowish brown to black, more or less streaked and intermixed with dull yellow. On each side thero Is a broad, yellow, undulating undulat-ing line, moro or less strongly mottled with red It closely resembels the common army worm and owes Its namo to the fact that, originating In the south, It makes its way northward as tho season advances, attacking fresh vegetation of almost every sort that it encounters on its way. Ordinarily thero are from three to four or even five generations of tho fall array worm In the course of a year. The worms, when full grown, descend an inch or two Into tho ground in order to pass into the pupal state preparatory to emerging as the adult moths which lay the eggs for the noxt generation of worms. This habit of descending Into the ground to enter pupation is of great import ance in tho control of the pesL Shallow Shal-low cultivation will destroy from 50T to 00 per cent of the Insects pupating at any time, tho efficiency of the measure depending upon tho thoroughness thorough-ness with which tho work is dono. In alfalfa the use of tho spiked-tooth harrow or tho alfalfa cultivator Is best unless it Is known that disking Is not Injurious to tho plants. Cultivation of tho ground between the rows of corn has been found to destroy nearly all of the pupao, thereby preventing the development of another generation. genera-tion. When fields are threatened with in-vnslon. in-vnslon. but have not as yet become actually infested, a deep fuddow should bo plowed out around "tho entire circumference of the field. Into this furrow tho advancing worms will fall. Thoy may then be killed by dragging a heavy log through the furrow, or, in sections where irrigation is possible, tho furrow may bo filled with water and a small quantity of kerosene sprinkled over the surface. This will kill tho worms almost Instantly. |
