description Asian Corn Borer Moth Overview
The Asian corn borer, Ostrinia furnacalis, is a crambid moth and an agricultural pest associated especially with maize in Asia and the western Pacific. Its larvae feed in the plant's whorl and later tunnel into stems, where the injury can kill growing tissue, stunt plants, weaken stalks, and cause breakage; they may also enter corn ears. This larval boring habit makes the species important to maize growers and entomologists studying crop damage.
help Asian Corn Borer Moth FAQ
What is the Asian corn borer?
The Asian corn borer is the crambid moth Ostrinia furnacalis. It is a major maize pest associated especially with Asia and the western Pacific.
How do Asian corn borer larvae damage maize?
The larvae first feed in the plant's whorl and later tunnel into the stem. This can kill growing tissue, stunt plants, and weaken the stalk.
Which part of the Asian corn borer causes the crop damage?
The larval stage causes the important crop injury. Adult moths reproduce, but the feeding and stem tunneling are carried out by the caterpillars.
Why is Ostrinia furnacalis important in maize production?
Its larvae can move from surface feeding into the stalk, making the damage harder to see and weakening the plant internally. The species is therefore an important agricultural pest in regions where maize is widely grown.
