Thelice are equipi)ed with tiny beaks and feed upon the stalk ofthe plant, hanging to the roots in clusters, robbing the rootsof the food necessary to sustain the stalk and leaves of theplant. Their presence can be determined by pulling or diggingup the plant, a careful inspection of which will reveal thebluish-green particles. The affected plants appear yellowand sickly and grow very slowly, or not at all. The lice dotheir greatest injury during May and June, and their attacksare usually in spots throughout the field adjacent to the ant 27 hills. The mjiiry done by these insects is variable andirregular, and they may be found in one locality whileanother quite close is entirely free from them. This is. CORN ROOT LOUSE. Winged and wingless varieties of the corn root louse.(Greatly enlarged.) due, doubtless, to the fact they have many enemies whichprey upon them, and they cannot thrive if these foes are The Corn Plant Louse The corn plant louse is closely related to the corn rootlouse, which it resembles. Its work is confined entirelyto the plant above ground, and it is less injurious than theroot louse. The general appearance and habits of the twoare so very similar that it is unnecessary to go into moredetailed description. 28 PART TWO DISEASES ;. Corn lias been generally considered less subject toattacks of fungous disease than other grain crops becausethere have been no widespread epidemics as with wheat,in the case of which rust sometimes destroys the entire cropover an extended area. However, such attacking diseasesas corn smut and other bacterial diseases of corn are wellknown and have always caused serious damage. Stalk F
