[7] These pests carry fungal pathogens (such as Bipolaris maydis and Curvularia lunata ) which cause diseases such as maydis leaf blight and curvularia leaf spot in the crop.
The European corn borer (Ostrinia nubilalis) and southern cornstalk borer (Diatraea crambidoides), formerly considered snout moths, are placed in the Crambidae which, as noted above, are usually regarded as a separate family today.

[5] There are also a limited number in the Solomon Islands, Africa, and parts of ...
Vascular infections primarily occur from wounds caused by stalk-boring insects, such as the larvae of the European corn borer, allowing for conidia to infect and colonize the xylem. [12] From this, anthracnose top die back (vascular wilt) or stalk rot can occur. In the fall, C. graminicola survives as a saprophyte on corn leaf residue. The ...
