KnoA'lton, associate professor of entomology at tne Utah State Agricultural college, slates. The paper should extend from below the surface of the ground up the stalk of the plant a few inches. Unee the paper is plao-.d ...und the plant, no further attention at-tention need be paid to it. As tne plant grows it Will be able to re-s re-s st the attack of the cutworm and t.ie expand. ng stem will push .ne paper out of tne way. Cutworms may best be killed Aith gra.-.sli upper bait consisting ef bran and sodium arsinate. Cultural Cul-tural control measures include chan cultivation, irrigation, rotation ro-tation of crops, and fall and early s-pr.ng pbw.ng to kill the worms in their hibernating stages and 10 d.scourage egg laying. Other methods oi control include running run-ning poultry and hogs over the ields to destroy the worms and pupae, and the use of light traps or capturing adults. T.ie many species of injurious cutworms all are the caterpillars of night flying ,moth, known as "milieis" and owlet moths. The female moths of many species lay .heir eggs during the early spring eiiher upon the ground or upon a host plant. In many species, maturity is reached during late rsummer or fall with pupation ccurring in the soil over the winter. Still other cutworms .urvive th? winter under the surface of the ground, as partly-srown partly-srown or nearly mature caterpillars. caterpil-lars. The heavy outbreak of ar,my cutworms now damaging alfalfa, vheat, and pasture and range plants, is one of the species which passes through the winter as a partly grown cutworm. |
