The European corn borer (Ostrinia nubilalis), also known as the European corn worm or European high-flyer, is a moth of the family Crambidae. It is a pest of grain, particularly maize ( Zea mays ). The insect is native to Europe, originally infesting varieties of millet , including broom corn .
The Asian corn borer, Ostrinia furnacalis, is one of the biggest pests of maize in Asia, causing 10%-30% of yield losses in the field, and in some cases up to 80% yield loss. [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 is perhaps the best known; introduced to the United States in the early 1900s, it is now widespread in all but the westernmost states.
Corn line MON802 was developed through genetic modification to be tolerant [3] to glyphosate herbicide and protect the plant from the European corn borer (Ostrinia nubilalis) (the Bt trait). [4] MON 809 is an Insect Resistant maize under license from Monsanto. [5]
Late in the year 1917 the widely distributed European and Asiatic pest Pyrausta nubilalis Hubn., a moth whose larva is a borer, was discovered to have become established in an area approximately of 100 square miles (259 km 2) in several counties in eastern Massachusetts, where it caused serious injury to corn and particularly to sweet corn. The ...

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 ...
Like the European corn borer, this moth is susceptible to Bt corn, a crop which has been genetically modified to produce Bt toxin that harms the moth. This corn has been introduced to the Philippines, where it has been monitored to gather data on its relationship with the moth. It has been successful, producing higher yields than conventional ...
