In all thefields examined, however, the work of the adult root-worms was muchmore common than the work of the cut-worms. In general, farmers do not distinguish clearly between the work ofthe adult corn bill bugs on young corn and the work of the southerncorn root-worm. The work of the corn root-worm is most conspicuous2 16 The Bulletin about tlie time the corn is sprouting. At this time the .seed leaf isvigorous and green and the unfolding leaves (bud) are withered anddead in those stalks that have been attacked by the root-worm. (Fig. 9.)On the other hand, in stalks attacked by the corn bill bugs all the leavesremain fresh and green at this time and later the whole plant dies if itis severely attacked. These young stalks usually show the character-istic rows of holes acoss the leaves. (Fig. 10.). Figure 7. Portion of a corn leaf showingcharacteristic arrangement of feedingpunctures.
