Abstract

Egg masses of corn borer ( Pyrausta nubilalis (Hbn.)) and/or inoculum of Fusarium graminearum Sehw. were introduced into artificial tunnels in corn stalks of single crosses WF9 × M14 and Oh43 × Oh51A growing in the field. The amount of necrotic tissue in stalks infested with corn borer larvae was always greater than when stalks were not infested. The presence of F. graminearum in tissue infested with corn borer larvae resulted in more rapid development of the larvae. Artificial inoculation of tunnels with F. graminearum had no apparent effect on numbers of corn borer larvae in the tunnels or the ability of the larvae to colonize the tunnels.
