Abstract:On whorl-stage com. mast of the larvae of Diatraea graudiosella Dyar moved from the site of hatch to .the inner whorl where they fed for about 10 days on Immature leaves. Then the larvae left the whorl zone, moved down the stalk, bore(l into the stalk, and tunneled. On tassel-stage corn. most newly hatched larvae moved into the middle (ear) zone of the corn plant and fed 7-9 days between the husk layers of the primary ears and ear shoots. Later, they fed on the kernels, cob, and shank of the car. Their movement from the primary cars and ear shoots to the stalk occurred mostly between 15 and 20 days after egg hatch.
