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), 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 .

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 ...

[11] Under biological control practices, a variety of methods can be used against the borer at one time. This would include the introduction of predators or parasites. [12]

A 2018 study found that Bt-corn protected nearby fields of non-Bt corn and nearby vegetable crops, reducing the use of pesticides on those crops. Data from 1976 to 1996 (before Bt corn was widespread) was compared to data after it was adopted (1996–2016). They examined levels of the European corn borer and corn earworm. Their larvae eat a ...
